Model 9200 Programmable Dual-loop Controller
percent output. The atmosphere data is the high limit point for the atmosphere percent output. This alarm remains active until the program ends.
ID_SET This “opcode” is used to set the ID number to the value specified in the temperature data. The atmosphere and option data are not used. The ID number is provided as a feature to track loads or jobs and is not used by any controller.
ID_INC This “opcode” increments the ID number by one. No data is required.
ID_INQUIRY This “opcode” is used to compare the ID value to the value in the temperature data. The option data is equal, high, or low. The LIMIT “opcode” immediately following this “opcode” sets a time limit on the wait. A BRANCH “opcode” immediately following this “opcode” can be used to change the program flow based on the inquiry results.
JUMP The JUMP “opcode” is used to goto another program when no return is needed. The option data is the program number to execute next.
LIMIT This option is used to place a time limit on a wait or inquiry step. The option data is the time limit to wait in hours and minutes. Should the time run out before the wait or inquiry is satisfied an alarm occurs.
LOW_AL This “opcode” is used to enable a low limit alarm on the temperature process and/or the atmosphere process. The temperature data is the low limit point for the temperature process. The atmosphere data is the low limit point for the atmosphere process. This alarm remains active until the program ends.
LOW_PO This “opcode” is used to enable a low limit alarm on the temperature percent output and/or the atmosphere percent output. The temperature data is the low limit point for the temperature percent output. The atmosphere data is the low limit point for the atmosphere percent output. This alarm remains active until the program ends.
MV_INQ The millivolt inquiry is used to wait for the probe millivolts to reach the value specified in the atmosphere data.
The options are:
•wait, reach within band;
•wait up, reach or exceed the value;
•or wait down, reach or be less than the value.
The LIMIT “opcode” immediately following this “opcode” sets a time limit on the wait.
A BRANCH “opcode” immediately following this “opcode” can be used to change the program flow based on the inquiry results.
PID Select This is a PID select “opcode”. The PID’s stored at PID Select Screen can be implimented for furnace control. The option values are Loop 1, Loop 2 and Loop 3 PID’s.
PO_INQ The percent output inquiry is used to test the actual percent output of the temperature and/or atmosphere controller.
