Setting
range
Set the time from when the deviation falls within the PID output hold
range until the PID output is held.
Set the range in which the PID output is held.
The PID output holding is disabled.
Set the time from when the priming operation starts until the main pump
starts.
The PID priming pump function is disabled.
Set the stirring time.
Set the interval time for the stirring operation.
Increase the set point before the PID output suspension function is
activated.
The PID sleep boost function is disabled.
Set the waiting time for the sleep boost operation.
Set the time from when the deviation reaches the output interruption
cancel level until the output is started.
Set the deceleration time for the check valve deceleration function.
The check valve deceleration function is disabled.
Set the frequency at which the check valve deceleration stops.
The check valve deceleration function is disabled.
Set the time from when the measured value reaches the lower limit pre-
warning level (Pr.1371) until the set point change is started.
As set in Pr.1370.
Set the time from when the measured value reaches the pre-warning
level (Pr.1371) until the set point change is started.
Set the operation range for the PID upper/lower limit pre-warning
function.
The PID upper/lower limit pre-warning function is disabled.
Set the set point change amount for the PID upper/lower limit pre-
warning operation.
Set the set point change rate for the PID upper/lower limit pre-warning
operation.
Set the deviation level for operating the auxiliary pressure pump.
Set the deviation level for stopping the auxiliary pressure pump.
Terminal 1 pressure input
Terminal 2 pressure input
Terminal 4 pressure input
The PID input pressure control function is disabled.
Set the input pressure warning level.
Set the input pressure fault level.
The input pressure fault detection is disabled.
Set the set point change amount when the pressure reaches the input
pressure warning level.
The protective function (E.PID) for the input pressure fault is activated.
A deceleration stop is performed when the input pressure fault occurs.
