5.12.3 Input Functions

Available input functions are shown in Figure 5-18.
Some inputs will trigger an indicator LED on the user
interface and/or display a message on the LCD screen
when they are activated.
All of the inputs may be assigned to either one or both of
the common alarms.
Note: Some models have factory-set input functions as
shown in Figure 5-17.

Forced Transfer to OFF Input. This function requires

transition model transfer switch.
accessory is not available for bypass/isolation switches.
Activation of this input signals the transfer switch to
transfer immediately from Source E to the OFF position.
The transfer switch then transfers to Source N if it is
available, executing the applicable time delays.
See Section 8.11 for more information about the load
shed (forced transfer to OFF) function.

generator set and transfers to the standby source,
ignoring the engine start time delay. The pre/post-
transfer, delayed-transition time delays, and in-phase
monitor will be active if enabled.
When the peak shave signal is removed, the load
transfers back to the preferred source. The pre/post-
transfer, delayed-transition, and engine cooldown time
delays, along with the in-phase monitor if enabled, will
be executed.
If the standby source is lost during peak shave, the unit
will transfer back to the preferred source.
See Section 5.14.8 for information about the Peak
Shave TD Bypass.
Remote Bypass Time Delay Input. Allows a remote
signal to end an active time delay. The signal ends only
the time delay that is active at the time the signal is
applied. Repeated signals are required to end
additional time
