Note 1
Set a negative value as the lower deviation limit (E1). If a positive value is set, a temperature
higher than the SP value will be used as the operating point.
Example:
Enter “-10” to set an operating point of SP-10

Note 2
Heater line break/overcurrent and control device short-circuit alarm.
Models with a current transformer input detect heater line breaks, overcurrent conditions
and control device short-circuit alarms by input from the current transformer.
• Heater line break/overcurrent alarm (operation type: 7)
Heater line break:
This alarm is activated when the current at control output ON is
lower than the event setting (Ex Low). Set Ex High to “9999” to
disable the overcurrent alarm.
Overcurrent:
This alarm is activated when the current is higher than the event
setting (Ex High) when the control output is ON. Set Ex Low to
“1999” to disable the heater line break alarm.
• Control device short-circuit alarm (operation type: 8)
This alarm is activated when the current is higher than the event setting (Ex) when control
output is OFF.
Note
●
The current display (
C
t
) in the operation mode indicates the current value when the
control output is ON. This displayed current value is not updated when control output
is OFF and for 300ms after control output changes to ON.
Detection of the current value is not updated for 300ms after the current output state
changes.
