Heater burnout alarm
setting range
*1
*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).
0.1 to 49.9 A (in units of 0.1 A)
Minimum detection ON time: 100 ms
SSR failure alarm
setting range
*2
*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).
0.1 to 49.9 A (in units of 0.1 A)
Minimum detection OFF time: 100 ms
Heater overcurrent
alarm setting range
*3
*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).
0.1 to 49.9 A (in units of 0.1 A)
Minimum detection ON time: 100 ms
