RGC..M Mode of Operation (continued)

SSR Over Temperature:

The SSR is equipped with internal temperature monitoring to prevent SSR damage in case of overheating conditions. Upon

detection of such a condition the SSR output is switched OFF and an alarm is issued accordingly. This alarm is visually

indicated by the red LED which is fully ON. Once the temperature cools down, the alarm is cleared and if control is still ON

an attempt to re-start the SSR is made.
