accuracy
Heater burnout alarm 0.1 to 49.9 A (in units of 0.1 A)
setting range *1
Minimum detection ON time: 100 ms
SSR failure alarm setting 0.1 to 49.9 A (in units of 0.1 A)
range *2
Minimum detection OFF time: 100 ms
Heater overcurrent alarm 0.1 to 49.9 A (in units of 0.1 A)
setting range *3
Minimum detection ON time: 100 ms
*1. For heater burnout alarms, the heater current will be measured
when the control output is ON, and the output assigned to the
alarm 1 function will turn ON if the heater current is lower than the
set value (i.e., heater burnout detection current value).
*2. For SSR failure alarms, the heater current will be measured when
the control output is OFF, and the output assigned to the alarm 1
function will turn ON if the heater current is higher than the set
value (i.e., SSR failure detection current value).
*3. For heater overcurrent alarms, the heater current will be
measured when the control output is ON, and the output assigned
to the alarm 1 function will turn ON if the heater current is higher
than the set value (i.e., heater overcurrent detection current
value).
