1 EX-P0 General The EX-P0 is a high performance ramp/soak controller with a storage capacity of segments in patterns. Each pattern consists of up to segments and patterns can be linked for maximum pattern storage. This instrument can store up to PID memory areas and alarm memory areas so the most suitable PID parameters and alarm settings can be selected for each segment. The EX-P0 has a unique front panel with a program pattern card to simplify program pattern checking. There is also an audible verification of key operation. Standard features include a wide range of inputs and outputs such as digital inputs for control status change between eset, un, Hold and Step, pattern end output, external contact input and control outputs. Optional features include dual alarms, analog retransmission output, heater break alarm, digital communication and position proportional control action. Features Multi-memory area Autotuning learning function Digital communications Three control modes Time signal outputs External contact input At-a-Glance Monitoring The program pattern number and segment under execution can be monitored from the front panel. The program's progress can be more easily followed if a program pattern card is used. This allows the operator to draw the time and temperature profile to see in real-time where the LED's traverse along the program. Multi-Memory Area The EX-P0 ramp/soak controller's PID and alarm memory areas are independent so that you can select the most suitable one for each segment. Each of the PID memory areas can store PID parameters, output limit High, output limit Low, deadband for position proportional control and differential gap for O/OFF control. The alarm memory areas can store ALM, ALM and heater break alarm set values. Pattern under execution (o.) Segment under execution (o.)

Memory X Autotuning Learning Function The PID values obtained may not be ideal for all set points within a given program. The use of the autotuning learning function (AT) allows a maximum of eight optimum PID values to be obtained automatically for use in the program. Three Control Modes The control mode can be easily changed to either ramp/soak, fixed set point or manual mode.. amp/soak control mode. Fixed set point control mode. Manual control mode Conventional model AT key to be pressed AT key to be pressed at each level (shown ) according to program progress EX-P0 Autotuning is executed automatically at each soak level without executing program.

Each pattern can be linked together so that it is possible to have a program with a maximum of segments. An optional communications interface, S-C or S-A, is available for networking to computers, PLCs and SCADA software. Up to units can be interfaced on one S-A communication line. patterns epeat (n times) Pattern o. ESET EX-P0 U FIX MA SET Host computer Time Signal Output o. o. o. Pattern o. Pattern o. Pattern o.

Either the process, set, or manipulated value can be produced in DC voltage or current. Heater Break Alarm The heater break alarm (HBA) function monitors the load via an external current transformer and detects failures in the control circuit such as heater breaks and the failure of a mechanical or solid state relay. When the control output is on and the load current drops below the HBA set value, the heater break alarm is activated. Conversely, when the control output is off and the load current still exists, the heater break alarm is turned on.
