HB and HS Alarms (for Controller with Heater Burnout and HS Alarms)
Note (1) When the control output 1 ON time is less than 190 ms, heater burnout detection and heater current
measurement are not performed.
(2) When the control output 1 OFF time is less than 190 ms, HS alarm and leakage current measure-
ment are not performed.
