Power-fail Recovery Modes
The timer facilitates 3 different power-fail recovery modes, viz.,
Continue
,
Re-start
and
Abort
. In
Continue
mode, the timer
resumes to execute the balance soak time once the PV is detected within Hold Band. In
Re-start
mode, the timer executes the
complete set time all over again. In
Abort
mode, the timer stops execution until a start command is issued.
End-of-Soak Events
The output Relay/SSR modules, OP2 and/or OP3, can be configured as End-of-Soak Alarm with a settable alarm duration.
That is, upon completion of Soak Time execution, the Relay energizes (say, to activate a buzzer) for the set alarm duration.
Additionally, the controller provides ‘Output-Off’ strategy that can be enabled to force the control output OP1 off upon End-of-
Soak. The output becomes active again after issuance of Start Command for the execution of a new Soak Time Cycle.
