(loop break detection time)
The loop break detection time is set in
minutes and seconds. By setting 00.00,
the alarm will turned ON only at an
abnormal input (overrange/
underrange, burn-out etc.). (00.00
~99.59)
(heater break detection current value)
The heater break detection current
value is set in the unit of ampere.
(1~50A)
(heater current value)
Displays the current in the heater.
This parameter cannot be changed.
(0~50A)
Supplementary descriptions
1. If during normal operation, the output (MV value) to switch to less 0% or
more 100%, and the input (PV value) not moved more than ±3%FS
elapsed the time defined in
parameter, then the
message will appear and loop break alarm turns ON.
2. This device provides the heater current monitor function (for only the
heater break option-fitted type). The current value is displayed in parameter
. This can be used as reference when determining the heater break
detection current value.
3. The heater current measured value is read only when the control output-1
relay is on. When that relay is off, the value at the point immediately before
the relay is set off is retained.
