6. Write the input shift.
Refer to the above procedure and replace the allocation change code
“C110” with “C660” and write it as the input shift.
7. Return to the original status.
Refer to the above procedure and replace the allocation change code
“C110” with “C070” and execute and then write the set point so that the Tem-
perature Control Unit will return to the original status (i.e., the status when
turning on the Temperature Control Unit).
Note The IOTC(––) instruction can be used with CQM1H CPU Units with lot number
0160 or later. If the ALLOCATE I/O command is sent, up to 250 ms may be re-
quired to received a response just after power is turned ON. Program the CPU
Unit so that this command is not sent within the first 100 ms after power is turned
ON.

Troubleshooting
Error
Control output
Remedy
Watchdog timer error
“EEEE” PV data for
control loops 1 and 2.
Will be OFF for
control loops 1 and 2.
Turn the power supply off and then back on. If
the error persists, replace the Unit.
RAM read/write error
“E100” PV data for
control loops 1 and 2.
EEPROM error
“E120” PV data for
control loops 1 and 2.
Setting range error
“EE01” PV data for
control loops with error.
Control will be normal.
Reset the SV to within the proper range.
Sensor error
“E400” PV data for
control loops with error.
Will be OFF for
control loop with error.
Check the connections to the input sensor and
cold junction compensator. If connections are
correct for both the input sensor and cold
junction compensator, replace the Unit.
