6 3. Product description Delivered items 3.1. Delivery configuration The scope of delivery encompasses: DT1100 xx xx xx PS documentation: this operating instructions certification warranty 3.2. Type designation Area of application 3.3. Principle of operation The DT1100 xx xx xx PS Isolators, Isolator / Power Supplies provide signal transmission and conversion between transmitters and signal processing units. The instruments feature complete 3-way isolation: the input, the output and the power supply are isolated from each other. The DT1100 xx xx PS Isolators may be used for isolating active output transmitters, the DT1100 xx xx TS PS Isolators / Power Supplies - providing a 18 VDC, 25 ma supply on the input - may be used for isolating and supply passive transmitters but it can be used for active output transmitters too. The current output all of the isolators can be active (A) or passive (P) V1

7 Operating principle Power supply The instruments are powered from a V AC/DC supply through a dual output high frequency flyback converter. One output supplies power for the input side and supplies power for the transmitter connected to the input (in case of the TS type), the other output supplies power for the output side. The signal isolation is provided by high isolation optocoupler. The DC signal transmission based on a high precision pulse modulation-demodulation principle. The instrument works from V AC/DC mains voltage. The power consumption is 1.6 VA (max.). The overcurrent protection in installation is 4 A (B) Adjustment A DT1100 xx xx xx PS doesn t need any adjustment. After connecting to the mains the instrument ready to work Indicator The following figure shows the indicator on the DT1100 xx xx xx PS front panel. 1. The power green indicator shows that the instrument is in power on state V1 7

8 3.6. Storage and transport DT1100 xx xx xx PS This instrument should be stored and transport in places whose climatic conditions are in accordance with chapter 8.1 Technical specifications, as described under the title: Environmental conditions. The packaging of DT1100 xx xx xx PS consist of environment-friendly, recyclable cardboard is used to protect the instrument against the impacts of normal stresses occurring during transportation. The corrugated cardboard box is made from environment-friendly, recyclable paper. The inner protective material is nylon, which should be disposed of via specialized recycling companies V1

9 4. Mounting 4.1. General instructions The instrument should be installed in a cabinet with sufficient IP protection, where the operating conditions are in accordance with chapter 8.1 Technical specifications, as described under the title: Operating conditions. Mounting position The DT1100 xx xx xx PS is built in a plastic housing, for mounting on TS-35 rail. The instrument should be mounted in vertical position (horizontal rail position). Horizontal mounting may cause overheating and damage of the instrument Main dimensions of the instrument V1 9

10 4.3. Mounting procedure DT1100 xx xx xx PS The following figure shows the mounting procedures (fixing on the rail): Mounting on the rail The mounting doesn t need any tools. 1. Tilt the instrument according to the figure; put the instrument s mounting hole onto the upper edge of the rail (figure step 1.). 2. Push the instrument s bottom onto the bottom edge of the rail (figure step 2.), you will hear the fixing assembly closing. 3. Check the hold of the fixing by moving the instrument firmly V1

11 5. Connecting 5.1. Preparing the connection Always observe the following safety instructions: Connect or disconnect only in the complete absence of line voltage If overvoltages are accepted, overvoltage arresters should be installed You should take note the data concerning on the overcurrent protection in installation. Use only a screwdriver with appropriate head Select connection cable Preparing cables Take note the suitability of the connecting cable (wire cross-section, insulation, etc.). You may use either solid conductor or flexible conductor. In case of using flexible conductor use crimped wire end. In case of mains connection the wire cross-section should be 1.0 mm 2 (min.). Prepare the cable for the connection. Strip approx. 8 mm insulation. In case of using flexible cable, crimp the cable end V1 11

12 5.2. Connecting the transmitter The following figure shows the wiring plan, connecting the transmitter: Wiring plan, connecting the transmitter (see also Application example ) Be careful the polarity of the cables 1. Loosen terminal screws. 2. Insert the wire ends into the open terminals according to the wiring plan. 3. Screw the terminal in. 4. Check the hold of the wires in terminals by pulling on them firmly V1

13 5.3. Connecting the signal processing unit and the mains The following figure shows the wiring plan, connecting the signal processing unit and the mains: Wiring plan, connecting the signal processing unit and the mains (see also Application example ) Be careful the polarity of the cables 1. Loosen terminal screws. 2. Insert the wire ends into the open terminals according to the wiring plan. 3. Screw the terminal in. 4. Check the hold of the wires in terminals by pulling on them firmly. Checking the connections Put the instrument under supply voltage Check if the cables are connected properly (have you connected all the cables, have you connected to the right place, do not the cable-ends touch each other) Put the instrument under supply voltage. After you have completed the connections, put the instrument under supply voltage. If the connection is correct the green indicator give light and you can measure output current or voltage on the output of the instrument according to the measured value of the transmitter V1 13

14 6. Fault rectification 6.1. Fault finding The green indicator is dark check the mains voltage. If the mains voltage is OK: the instrument is defective. There is no output signal check the input signal. If the input signal is OK: the instrument is defective. There is no input signal check the transmitter supply. If the transmitter supply is OK: the transmitter is defective. When the result of fault finding is that the instrument is defective call the manufacturer service department Repairing There is no user repairable part inside the instrument. In accordance with Point 2.1.: For safety and warranty reasons, any internal work on the instrument must be carried out only by DATCON personnel V1

15 7. Dismounting 7.1. Dismounting procedure Before dismounting take note the warnings written in Chapter 5.1. The following figure shows the dismounting procedures: Dismounting from the rail The dismounting procedure needs a screwdriver for slotted screws. Before dismounting disconnect all wires. 1. Put the screwdriver end into the fixing assembly s hole (figure step 1.). 2. Lift the screwdriver handle until it possible to open the fixing assembly (figure step 2.). 3. Keeping the screwdriver in this position lift the instrument bottom from the bottom edge of the rail (figure step 3.). Lift the whole instrument (you may put out the screwdriver) (figure step 4), the instrument will be free Disposal According with the concerning EU directive, the manufacturer undertakes the disposal of the instrument that are manufactured by it and intended to be destroyed. Please deliver it in contamination-free condition to the site of the Manufacturer or to a specialized recycling company V1 15
