6 --- Remote Control & Load Disconnect
These remote control features require a customer–
supplied normally–closed contact suitable for a 5 V dc
low energy circuit. Refer to the wiring diagram provided
with the ATS. Activate the appropriate DIP switch S3
with the ATS. Activate the appropriate DIP switch S3
actuators as shown in Tables E, F, or G. See Figure 7.
Remote test
Normally–closed input. When opened, it simulates a
utility failure. The generator is signalled to start
immediately and the load transfers to the generator (if
immediately and the load transfers to the generator (if
acceptable). If the generator fails, the load stays on the
generator until the remote test circuit is closed.

Remote test (with automatic retransfer)
Normally–closed input. When opened, it simulates a
utility failure. The generator is signalled to start
immediately and the load transfers to the generator (if
immediately and the load transfers to the generator (if
acceptable). If the generator fails, the load transfers
back to the utility (if acceptable).

Load disconnect feature
Connect external circuits to the terminals indicated on
the wiring diagram. The double throw (Form C) contact
operates prior to a selectable 0, 3, 10, or 20 second delay
operates prior to a selectable 0, 3, 10, or 20 second delay
before transfer of the ATS. The contact resets either
immediately following transfer or after the same delay as
set for presignal before transfer. Time delay between the
set for presignal before transfer. Time delay between the
load disconnect control signal and initiation of transfer is
set on the controller DIP switch S3 (actuators 6, 7, 8).
* Enabling the delay after transfer will cause the control signal to reset
after the same delay as set for the delay before transfer.
