■ Heater Burnout Alarms and SSR
Failure Detection Alarms
(E5CN Models with Heater Burnout and SSR Failure Detection
Alarms)
Note: 1. If the ON time of control output 1 is less than 190 ms, heater
burnout detection and the heater current will not be
measured.
2. If the OFF time of control output 1 is less than 190 ms, SSR
failure detection and the heater current will not be
measured.
