3 1. GENEA DESCIPTION The D64PBH13 is a ground fault relay for use on solidly grounded or resistance grounded systems over a frequency range of Hz. This innovative digital electronic relay measures ground fault current using either, a special Eaton s Cutler-Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1 or, the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1. Either C311CT is connected to the CT input terminals CT1 & CT2 The D64PBH13 reacts to alternating current only and will reject direct current signals. It will maintain accuracy over a frequency range of 40 to 200 Hz., making it suitable for variable frequency drive applications. The ground fault current trip level is set on 5 DIPswitches in 25 discrete steps. The range is 50 Amps Amps when using the 10,000:1 CTs and 2.5 Amps 60 Amps when using the 500:1 CTs. The trip level can be set just above the charging current 1. Any deterioration in the circuit will trip the relay. This also permits scheduled field testing of the relay (by lowering the trip level). 1 The capacitance-to-ground charging current on a system will vary depending on: the overall length of the cables; the types of loads; the quality of insulation on the phase conductors; the surrounding equipment grounding, cable trays, junction boxes, etc.; and, the type of transformer. A "ule-of-thumb" for systems 600 Volts and lower: The charging current is 0.5 Amps per 1000 kva of transformer capacity. The response time on ground fault trip is set on 4 DIPswitches. The range is 25 ms second in 14 discrete steps. The D64PBH13 is suitable for use on Service Protection Equipment applications. The Trip INHIBIT function can be Enabled or Disabled by means of a front accessible DIPswitch. The inhibit level is related to the ground fault trip level setting over a range of 200 Amps to 2000 amps when using the 10,000:1 CTs and 10 Amps 100 Amps when using the 500:1 CTs. With Inhibit Enabled, if the ground fault current exceeds the inhibit level, the output circuit breaker trip will be inhibited until the ground fault current drops below the inhibit level. A voltage-operated circuit breaker with an external toggle handle is used as the output device. It provides a visual indication of the status of its output contacts. The contacts are Form "C" N.O. - N.C. voltage free. They may be used to operate the upstream protective device and indicate a failure of the system. The circuit breaker can be set to operate in the failsafe or the non-failsafe mode by means of a front accessible DIPswitch. The circuit breaker mechanism is trip free (cannot be closed if a ground fault is being sensed by the relay). Manual reset of the circuit breaker toggle will restore the output contacts to the normal state. The circuit breaker toggle in the Tripped position indicates that the D64PBH13 has sensed a ground fault current higher than the trip level for a period longer than the trip time and that the output contacts have operated, or, if in the Failsafe mode, it will also indicate that the control voltage has been removed from terminals + & N-. The D64PBH13 constantly supervises the connection to the external CT. Open circuits are detected and will cause a trip. Please note that the D64PBH13 does not employ any DC injection to implement this since even small DC current sent through the secondary windings of a CT can bias its core enough to shift the trip point outside specification on sensitive settings. For the CT supervision to work, either the special Eaton s Cutler- Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1, or the standard family of Series A2 C311CT zero sequence current transformers with a turns ratio of 500:1 must be installed, as specified in section 3.2. A Cover mounted ESET button is standard. A green UN ED shows correct operation by slowly flashing (1 s on/ 1 s off) when control voltage is applied to terminals + & N-. A red ED shows short 0.25 s flashes as a code indicating the cause of trip: 1 flash every few seconds ground fault; 2 consecutive flashes Inhibit Backup; 4 consecutive flashes CT circuit open; 5 consecutive flashes Control Voltage lost in Failsafe mode (See Section 2.6 for explanation of memory feature); continuous consecutive flashes Trip Failed.

4 Pull-apart terminal blocks simplify connection of field wiring. They have two 12 AWG screw clamps per pole with 90 and 180 orientation. Captive screws secure the blocks to the relay, safe from the effects of shock and vibration. The D64PBH13 operates on a control voltage of Volts ac/dc. 2. OPEATION 2.1 GOSSAY OF TEMS Circuit Breaker Toggle - Normal: It is not necessary to apply control voltage to terminals + & N- before resetting the toggle of the circuit breaker to Normal. However, control voltage must be applied to terminals + & N- in order for the relay to sense a trip condition. With control voltage on terminals +& N- (green UN ED flashing), The Normal position indicates that the D64PBH13 is sensing a normal condition (no ground fault on the system being monitored). In the Normal position the output contacts are in the normal state: Terminals closed, Terminals open. Circuit Breaker Toggle - Tripped: With control voltage on terminals + & N- (green UN ED flashing), The Tripped position indicates that the D64PBH13 has sensed a ground fault current higher than the trip level for a period longer than the trip time and that the output contacts have operated. Also, if the D64PBH13 is in Failsafe mode, the Tripped position will indicate that the control voltage has been removed from terminals + & N-. In the Tripped position the output contacts are in the tripped state: Terminals open; Terminals closed. Manual eset: The toggle of the circuit breaker must be placed in the Normal position to reset the contacts to the normal state after a trip, providing the ground fault has been cleared or the measured values are within the preset limits. Non-Failsafe: The circuit breaker can be placed in the Normal position with or without control voltage being applied on terminals + & N-. Control voltage must be applied to terminals + & N- in order for the relay to sense a trip condition. With control voltage on terminals + & N- (green UN ED flashing), the circuit breaker will trip and the output contacts will change state when the measured values reach or exceed the DIPswitch settings for current and time. The Non-Failsafe mode is recommended for the circuit breaker Trip when being used with shunt trip devices. The circuit breaker should be equipped with a coil clearing contact in its shunt trip circuit. Failsafe: The circuit breaker can be placed in the Normal position with or without control voltage being applied on terminals + & N-. Control voltage must be applied to terminals + & N- in order for the relay to sense a trip condition. The circuit breaker will trip and the output contacts will change state when either or both of the following conditions occur: - The measured values reach or exceed the DIPswitch settings for current and time. - Control voltage is removed from terminals + & N-. The Failsafe mode is recommended for the circuit breaker Trip when being used with undervoltage devices. This includes: contactor coils; starter coils; and circuit breakers equipped with UV trip coils. September, 2009 Page 4

5 Trip Free: The output circuit breaker is 'trip free', meaning that its contact cannot be held closed against a fault by manually keeping the toggle in the NOMA position. Note however that this is only true when control voltage is present on terminals + and N-. Trip Inhibit: Contactors are not designed to interrupt high fault currents. Under these conditions the upstream short circuit protective devices, fuses or circuit breaker, should interrupt the fault. Trip INHIBIT function can be Enabled or Disabled by means of DIPswitch no. 11. The inhibit level is related to the ground fault trip level over a range of 200 Amps to 2000 amps when using the special Eaton s Cutler-Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1. With Inhibit Enabled, if the ground fault current exceeds the inhibit level the output circuit breaker will be inhibited until the ground fault current drops below the inhibit level. However, should the current fail to drop within 1.2 s, then, as a last resort, the unit will trip showing the Inhibit Backup Trip code on its red ED (2 flashes). It is advisable to replace the contactor after this event since it was used to break a current possibly well outside its rating. The inhibit level is related to the ground fault trip level over a range of 10 Amps to 100 amps, when using the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1. With Inhibit Disabled under the same conditions, the output circuit breaker will trip after the preset trip delay time. The INHIBIT function is useful when the D64PBH13 is being used to trip a contactor or motor starter on a solidly grounded system. In this application, there is no defined limit to the magnitude of ground fault current should a bolted ground fault occur. By inhibiting the trip it allows the upstream protective device to clear the fault. MEMOY AFTE OSS OF CONTO VOTAGE When control voltage is removed from the D64PBH13, the AST TIP registration will be memorized (for at least one week). Pressing the eset pushbutton before restoring control voltage will light either the green ED or the red ED, green indicating no trip was registered and red indicating the opposite. The green ED will light continuously, whereas the red ED will give a sequence of short flashes as described in section 2.4 indicating the cause of trip. 2.2 DIPSWITCH SETTINGS efer to the figure on the front page of this manual. There is one 12 - position array of DIPswitches on the front of the D64PBH13. The factory setting of all DIPswitches is EFT (). Position 1-4: These four DIPswitches (1, 2, 3, & 4) are assigned to Ground Fault TIP DEAY settings. Position 5-8: These five DIPswitches (5, 6, 7, 8, & 9) are assigned to Ground Fault TIP EVE and TIP INHIBIT EVE settings. Position 10: This DIPswitch is reserved for use in the D64PBH15 relay Position 11: This DIPswitch is assigned to TIP INHIBIT MODE. Position 12: This DIPswitch is assigned to Output Circuit Breaker OPEATING MODE. September, 2009 Page 5

6 2.2.1 GOUND FAUT TIP DEAY The ground fault TIP DEAY time range is 25 milliseconds second. Table 1 provides a listing of the TIP DEAY settings, which can be made with DIPswitches 1 through 4 on the 12 Position Array. The Trip Delay begins when the ground fault trip level setting is reached or is exceeded. Table 1: Ground Fault Trip Delay DIPSWITCH SETTINGS TIME DEAY IN MIISECONDS =EFT =IGHT * * Factory Setting Set the ground fault TIP DEAY to provide the desired delay before the output relay will trip when the ground fault TIP EVE setting is reached or exceeded. The setting should be selected to co-ordinate with other ground-fault devices connected on the same transformer secondary: set shorter than upstream devices; set longer than downstream devices. If no other ground-fault devices are connected, set for the shortest time GOUND FAUT TIP EVE The ground fault TIP EVE range is either Amps when using the special Eaton s Cutler- Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1 or Amps when using the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1. The following table provides a listing of the TIP EVE settings, which can be made with DIPswitches 5 through 9. The ground fault TIP EVE setting determines the inhibit level (when inhibit is enabled). September, 2009 Page 6

7 Table 2: Ground Fault Trip evel DIPSWITCH SETTINGS EVES WHEN USING C311CTs WITH 500:1 TUNS ATIO TIP EVE INHIBIT EVE =EFT IN AMPS IN AMPS =IGHT (When INHIBIT is Enabled) As indicated in the General Description, it is recommended that the ground fault TIP EVE setting be kept as close to the charging current as possible. This will provide maximum safety for operating personnel and equipment protection. On resistance grounded systems, the TIP EVE setting should be set lower than 20% of the Neutral Grounding esistor let-through current. If the measured ground fault current exceeds the TIP EVE setting, the output circuit breaker will trip after the pre-selected TIP DEAY TIP INHIBIT MODE TIP INHIBIT is described under the glossary of terms. The setting of DIPswitch 11 determines if TIP INHIBIT is disabled or enabled. This is shown in Table 3.

8 2.2.4 OUTPUT CICUIT BEAKE OPEATING MODE CONTACT STATE The two different OPEATING MODES are described under the glossary of terms. The setting of DIPswitch 12 determines the operating mode of the D64PBH13 output circuit breaker. This is shown in Table 4. Use this table when deciding on field connections. The state of the output circuit breaker contacts is shown in Table 5. Also, refer to the CONNECTIONS section. Table 4: Output Circuit Breaker Operating Mode DIPSWITCH SETTINGS 12 =EFT =IGHT OUTPUT CICUIT BEAKE OPEATING MODES * NON-FAISAFE FAISAFE * Factory Setting 2.3 TAMPE POOF DIPSWITCHES Eleven of the twelve DIPswitches are used to program the D64PBH13. However, to discourage unauthorized manipulation, the preselected settings can only be changed by going through the procedure outlined below. When an attempt is made to change the settings without going through this procedure, the green and red EDs start to blink alternately until the switches are returned to their original positions. Should the switches be left in other than the preselected settings, the preselected settings, being stored in nonvolatile memory, remain valid. The proper procedure to change settings is as follows: 1. The dipswitches are placed in the new positions (ignoring the blinking EDs). 2. Within 15 seconds after the last change was made (or control power was applied), the system is brought in test mode using the local pushbutton, causing the new settings to become active. Since the system will trip now, changing the settings cannot go by undetected. See section 2.5 for a description of how to invoke test mode. Note that any trips must be reset before this procedure can be completed. 2.4 INDICATION There are two ED s on the front of the D64PBH13. - A green UN ED shows correct operation by slowly flashing (1 s on/ 1 s off) when control voltage is applied to terminals + & N-. - A red AST TIP ED shows short 0.25 s flashes as a code indicating the cause of AST TIP: - One flash every few seconds means that the ground fault current exceeded the set G/F Trip evel during the G/F Trip Delay time.. In case the G/F Trip Inhibit function is enabled, the ground fault current may have exceeded the Trip Inhibit evel (overriding the G/F Trip Delay time), but in that case the upstream tripping device tripped correctly within 1.2 s and after the current dropped to zero as a result of that, the D64PBH13 activated its output circuit breaker to isolate the faulty circuit. This trip is labelled Ground Fault. September, 2009 Page 8

9 - Two.25 s flashes every few seconds means that the ground fault current exceeded the Trip Inhibit evel but the upstream device failed to trip during 1.2 s. The D64PBH13 then tripped as a last resort. The contactor should be replaced since its contacts may well be damaged. This trip is labelled Inhibit Backup. - Four 0.25 s flashes every few seconds means that the connection of the external CT is open circuited. Note that the trip is latched until reset; therefore intermittent failures will be captured, overcoming the impression that the D64PBH3 tripped without cause. This trip is labelled CT Open Circuit. - Five 0.25 s flashes every few seconds means that control voltage was lost while the D64PBH13 was in the Failsafe operating mode. The ESET pushbutton must be pressed before restoring control voltage to activate this indication. - Continuous 0.25 s flashes indicate an extra trip failed alarm state on top of one of the possible trips described above. Following the operation of the output circuit breaker, measured ground fault current remained at a high level. When the local reset button is first pressed, the trip is not reset, but the trip failed alarm state is. As a result the red ED will now show the original cause of trip. This alarm is labelled Trip Failed. Please note that the red ED is a convenient indicator only. It does not affect the operation of the output circuit breaker. After a fault is cleared, the user may or may not decide to reset the ED. A subsequent fault will cause the indication to be updated in either case. 2.5 G/F TEST - ESET G/F TEST INTENA Double-clicking the built-in ESET TEST pushbutton invokes a test which switches an AC voltage onto the processor s CT sensor input. The voltage is scaled to simulate a Ground fault current of 1.5 times the G/F trip level set point. The output circuit breaker will trip on G/F after the set delay (plus 0.4 s) and the AC test voltage will be switched off. The red ED will turn on solid. This proves that the internal electronics and output circuit breaker are functioning. Optionally, pressing the reset button again will reset the red ED enabling the green UN ED. eclose the circuit breaker (Normal position). No external power supply is required G/F TEST EXTENA Provision is made for external testing if required. efer to Figure 1. Select a momentary contact single pole normally closed pushbutton rated at least 3 Amps at 10 Volts ac. Connect as shown in Figure 1. When pressed the circuit to the external CT is opened. This results in a trip and the red ED will flash four 0.25 s flashes (CT Open Circuit). This proves that the current transformer is connected and the windings are okay, the CT monitor's detection circuit is operating, and the internal electronics and output circuit breaker are functioning. A Test ecord Form is included in this instruction manual. This form provides spaces to record the date the test was performed and the results. Those in charge of the building s electrical installation should retain the form in order to be available to the authority having jurisdiction ESET The built-in ESET TEST pushbutton is used to optionally reset the red AST TIP ED in the D64PBH13. The external pushbutton cannot be used to reset the red AST TIP ED. September, 2009 Page 9

10 2.6 MEMOY AFTE OSS OF CONTO VOTAGE When control voltage is removed from the D64PBH13, the AST TIP registration will be memorized (for at least one week). Pressing the eset pushbutton before restoring control voltage will light either the green ED or the red ED, green indicating no trip was registered and red indicating the opposite. The green ED will light continuously, whereas the red ED will give a sequence of short flashes as described in section 2.4 indicating the cause of trip. Please note that if the D64PBH13 is operated in the Failsafe mode (see section 2.2.4), and there was no trip when control voltage disappeared, the system will still activate the trip register and trip the output circuit breaker at the very moment of losing voltage. If this is what happened, the red ED will show five consecutive short flashes, meaning relay was merely activated because control voltage was lost while operating in Failsafe mode. The AST TIP registration is written to non volatile memory at the moment the D64PBH13 powers down. This way the trip code is accessible -by pressing the ESET button- even without control voltage present, which is particularly helpful when the tripping of the relay also causes control voltage to disappear. However, there is a very limited amount of backup power stored internally to support this, so the number of red flashes must be verified at the very moment when the button is being pressed. The backup power will hold for days as long as it is not exhausted by the pressing of the button. 3. INSTAATION INSTUCTIONS Place the D64PBH13 in a clean dry enclosure. Try to keep the exposure to mechanical shock and vibration to a minimum. The internal electronics have been encapsulated in epoxy to improve the performance in high vibration environments. ocate the relay close to the isolating device (circuit breaker or contactor) which is protecting the circuit being monitored. Provide maximum clearance between both the D64PBH13 and the C311CT and any strong magnetic flux producing devices such as power transformers, autotransformers, control transformers, reactors, and high power conductors and buswork. 3.1 MOUNTING efer to Figure 2 for mounting dimensions of the D64PBH13 relay. It is designed for through-the-door or rear panel mounting THOUGH-THE-DOO Four 4 mm (5/32") holes in the flanged cover of the relay permit bolting to the door using suitable hardware. A 102 mm high (4.0") x 72 mm wide (2.85") cut-out is required in the door. emove the pull-apart terminal block from the relay to permit the relay to be inserted through the cutout. From the front of the door, insert the relay through the cut-out. Mount the relay cover to the front of the door using the customer supplied mounting hardware (four bolts, washers and nuts) EA PANE The relay may be mounted with either mounting screws or 35 mm DIN rail. Two #8-32 x 3/4" (M4 x 20) mounting screws are required for screw mounting. For DIN rail mounting, the rail should be bolted to a flat surface. Install the DIN rail vertically. Allow at least 1" (25.4 mm) of rail to extend beyond each end of the relay. Install a stop block on the DIN rail 1" (25.4 mm) from the bottom to keep the D64PBH13 in position. Secure the relay to the DIN rail ensuring the white release latch at the left side of the relay engages the rail. September, 2009 Page 10

11 3.2 EXTENA C311CT CUENT TANSFOME The D64PBH13 is designed to operate with either, a special Eaton s Cutler-Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1 or, the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1. Each C311CT is epoxy molded for exceptional mechanical properties and has a high-grade silicon iron core for excellent coupling characteristics. C311CTs have built-in back-to-back zeners across the output terminals to provide maximum safety in the event of an open CT secondary circuit. efer to section 4 to select the catalog number of the C311CT current transformer with the opening required for the application.. Each C311CT is epoxy molded for exceptional mechanical properties and has a high-grade silicon iron core for excellent coupling characteristics. C311CTs have built-in back-toback zeners across the output terminals to provide maximum safety in the event of an open CT secondary circuit. Phase conductors must be insulated for the system voltage when it is higher than 660 Volts. efer to Figure 1. Pass the phase conductors through the CT window. If the neutral conductor is being connected downstream, it is to be passed through the window. Do not pass ground conductors through the CT window. In applications that require shielded wires to pass through the CT window, return the shields through the CT window before connecting them to ground. Position power cables in the center of the current transformer opening. Keep cables and buswork clear of the split on split core current transformers. 3.3 CONNECTIONS All connections to the D64PBH13 are by means of screw clamp terminals rated 10 Amps, 300 Volts. Terminals will accept #26-12 AWG solid or stranded conductors. The terminals are pull apart. They have two 12 AWG screw clamps per pole with 90 and 180 orientation. A screw mounted locking block is located at each end of the terminal block for maximum security. Since the relay housing is non metallic, no chassis bond is required. For good EMC behaviour the following wiring practices are recommended: - Connect the FB ( Frame Bond ) terminal to the structure ground as close as practically possible to the component being grounded using the shortest wire. - The D64PBH13 has an isolated power supply. Therefore the N- terminal should be connected to the structure ground at the same point as the neutral of the control transformer. See figure 1. - Avoid looping or coiling any/all wires connected to the component. - Dress all conductors as close as practically possible to the back panel or grounded frame. - Use shielded twisted leads on interconnection between CT and elay. - The shield should extend the full length of the twisted interconnection leads. - Connect shield to structure ground as close as practically possible to the elay. - When stripping conductor insulation care should be taken to avoid breaking any conductor strands. Connect Volt ac/dc control voltage to terminals + & N-. efer to Figure 1 and Table 4. Decide on the connection of field devices to output circuit breaker contact terminals by comparing the desired control of the field devices under various operating conditions. Figure 1 shows a typical connection of a 120 Volt ac circuit breaker shunt trip coil (ST) to the closed contact of the output circuit breaker. Comparing the output circuit breaker contact states, it can be seen that this could be used with the NON-FAISAFE operating mode. The N.C. contact, terminals 11 & 12, (open when the circuit breaker toggle is placed in the NOMA position) would be used for the shunt trip coil circuit. September, 2009 Page 11

12 Connect the external C311CT current transformer to terminal CT1 & CT2 of the D64PBH13, using 14 AWG (minimum) twisted conductors. If a remote Test button is being used connect as shown in Figure 1. CAUTION: Internally these terminals are connected to the FB terminal via a 2.5 V DC voltage source, shunted with a 7 V transients suppressing zener diode. DO NOT connect the external transformer to ground at any other point. 4.

19 PUB FOM 1 - TEST ECOD GOUND FAUT TEST D64PBH13 ESET G/F TEST INTENA Double-clicking the built-in ESET TEST pushbutton invokes a test which switches an AC voltage onto the processor s CT sensor input. The voltage is scaled to simulate a Ground fault current of 1.5 times the G/F trip level set point. The output circuit breaker will trip on G/F after the set delay (plus 0.4 s) and the AC test voltage will be switched off. The red ED will turn on solid. This proves that the internal electronics and output circuit breaker are functioning. Optionally, pressing the reset button again will reset the red ED enabling the green UN ED. eclose the circuit breaker (Normal position). No external power supply is required. Provision is made for external testing if required. efer to Figure 1. Select a momentary contact single pole normally closed pushbutton rated at least 3 Amps at 10 Volts ac. Connect as shown in Figure 1. When pressed the circuit to the external CT is opened. This results in a trip and the red ED will flash four 0.25 s flashes (CT Open Circuit). This proves that the current transformer is connected and the windings are okay, the CT monitor's detection circuit is operating, and the internal electronics and output circuit breaker are functioning. The built-in ESET TEST pushbutton is used to optionally reset the red AST TIP ED in the D64PBH13. The external pushbutton cannot be used to reset the red AST TIP ED. This form provides spaces to record the date the test was performed and the results. Those in charge of the building s electrical installation should retain the form in order to be available to the authority having jurisdiction. Year Jan. Feb. Mar. Apr. May June July Aug. Sept Oct.
