System Setup/Operational
Considerations 1. Allow at least a 30 minute warm-up period for the system to fully
stabilize.
2. When self-tuning is used, either a) turn the temperature controller and
load (e.g., heater) power ON simultaneously or b) turn the load power
ON before the temperature controller. Note: If the load is turned ON
before the temperature controller, correct self-tuning and optimum
control are no longer possible.
When operation is started after system warm-up, turn the power to the
system OFF once after warm-up is completed, and then turn the
temperature controller and load power ON simultaneously.
Note: Rather than turning the temperature controller power ON again,
moving from the STOP to the RUN mode is also possible.
3. The temperature controller may be subject to the influence of radio
interference if used near a radio, TV, or wireless equipment. Refer to
Appendix on page A-1 for additional information.
