MV AT STARTUP / MV AT STOP / MV AT ERROR
Specific MV values can be set for respective loop status.

With standard PID control, -5.00 is used for any value below -5.00.
With heating-cooling PID control, negative value is applied for cooling control.
With ON/OFF control, cooling control is turned on at -100.00, both cooling and heating is off at 0.00, and heating is on at
100.00.
With MANUAL control mode, the MV at startup is applied at the startup, however, once the Controller transits from AUTO
to MANUAL, the MV value at the moment of the transition is carried on.
The Controller’s action is determined in the following priority order: MANUAL > STOP > Error.
■
MV LOW LIMIT / MV HIGH LIMIT
Specify the lower and the upper limits for the MV.
For example, if the MV range is set to 0.00 − 50.00, setting 50.00 is used for setting 70.00 automatically.

ERROR ACTION
Specify the Controller’s action in case of an input error (burnout) or an error in the remote SP input.
ADDRESS

RANGE
DEFAULT
+205
Loop 1, Error action
0 : Operation continued
1 : ‘MV at error’ output

+461
Loop 2, Error action
With ‘Operation continued’ setting, the Controller continues operating.
With ‘MV at error’ output setting, it outputs the specified output value until the error is cancelled.
With STOP setting, the Controller stops operating. It does not restart automatically even when the error is cancelled.
■
CT ALARM ACTION
Specify the Controller’s action in case of an alarm by CT input (heater wire break, SSR shortcircuit failure or overload).
ADDRESS

RANGE
DEFAULT
+206
Loop 1, CT alarm action
0 : Operation continued
1 : ‘MV at error’ output

+462
Loop 2, CT alarm action
With ‘Operation continued’ setting, the Controller continues operating.
With ‘MV at error’ output setting, it outputs the specified output value until the error is cancelled.
With STOP setting, the Controller stops operating. It does not restart automatically even when the error is cancelled.
