3-11 Requests during Operation
1,2,3... 1. About four seconds is required for outputs to turn ON when the power is
turned ON. Take this into consideration when the temperature controller is
incorporated into a sequence circuit.
2. Allow at least 30 minutes for warming up.
3. When self-tuning is used, turn the temperature controller and load (e.g.
heater) ON simultaneously or turn the load ON before the temperature
controller. If the load is turned ON after the temperature controller, correct
self-tuning and optimum control are no longer possible.
When operation is started after warm-up, turn the power OFF once after
warm-up is completed, and then turn the temperature controller and load
ON simultaneously. (Instead of turning the temperature controller power
ON again, moving from the STOP to the RUN mode also is possible.)
4. The temperature controller may be subject to the influence of radio inter-
ference if used near a radio, TV or wireless equipment.
