Step 3: Setting the potentiometer
In this step, the timers for transfer time delays are set using the potentiometer. A screwdriver is required for this.
Procedure
-
Set the position of the potentiometers manually.
Two values are set simultaneously using one potentiometer:
-
The transfer time delay for source failure in seconds (0 to 30 s) and
-
The return time delay to prioritized source recovered in minutes (0 to 30 min)
Setting the potentiometer
Transfer time delay for source failure:
The timer is started when source failure is detected. If the source becomes available again before expiry of the timer, transfer
is not carried out.
Return time delay to prioritized source recovered:
The timer is started when the prioritized source becomes available again. The power supply is transferred to the prioritized
source after expiry of the timer. If the prioritized source fails before expiry of the timer, the transfer is not carried
out and the timer is restarted as soon as the prioritized source becomes available again.
NOTE
When settings are made on the potentiometer, the "Auto" LED remains illuminated without change.
