Function:
Programmable in 1 s increments. Once the Bypass Function is activated in accordance with the setting in par
24-10, the Bypass Delay Timer begins to operate. If the frequency converter has been set for a number of restart
attempts, the timer will continue to run whilst the frequency converter tries to restart. Should the motor have
restarted within the time period of the Bypass Delay Timer, then the timer is reset.
Should the motor fail to restart at the end of the Bypass Delay Time, the Drive Bypass relay will be activated,
which will have been programmed for Bypass in
par 5-41, On Delay
programmed in , [Relay] or
the relay action is performed.
Where no restart attempts are programmed, the timer will run for the delay period set in this parameter and will
then activate the Drive Bypass relay, which will have been programmed for Bypass in par 5-40, Function Relay.
If a Relay Delay has also been programmed in par 5-41, On Delay, Relay or
this time must also elapse before the relay action is performed.
