Note When using only one control loop, short-circuit the loop 2 input terminals. If
used with the terminals open, “E400” (PV error) will be read into the CPU Unit
for approximately 10 seconds when power is turned ON.
• Do not touch or remove the cold junction compensator. (CQM1-TC001/
TC002)
• Connect to loop 1 terminals and turn ON pin 5 on SW1 when using only
one control loop.
• Use the input sensor set on the function DIP switch.
