Source Names

The controller uses various designations for the
sources. Source S1 is connected to the Normal side of
the transfer switch. Source S2 is connected to the
Emergency side of the transfer switch. In a typical
application, Source S1 is the utility source, and source
S2 is the standby generator set. Other applications may
use different configurations, such as the gen-gen
configuration which uses two generator set sources and
no utility.
The Preferred Source is the source that will be used if
both sources are available. Typically, this is the normal
utility source, S1. The Set Preferred Source menu
allows the operator to select either source as the
preferred source. Source S2 (connected to the
emergency side of the contactor) can be set as the
preferred source using this menu. See Section 5.11.3
for more information about preferred source selection.
In the load control setup menus, N is the preferred
source and E is the standby source.

Controller DIP Switches

Two DIP switches on the main logic board are assigned
functions. Switches 3 and 4 are not used. The DIP
switches are located on the controller's main logic board
on the inside of the enclosure door. Figure 5-1 shows
the locations of the switches on the controller circuit
board. It is not necessary to remove the logic assembly
cover to see or adjust the DIP switches.
SW1-1, Password Disable. Turning ON the password
disable DIP switch SW1-1 disables the setup password
and resets it to the factory defaults. When the switch is
ON, system setup and programming is allowed without
the need to enter a password.
Note: Disable the setup password only during service
unless the transfer switch is installed in a secure
location.
Turning DIP switch SW1-1 ON and then OFF resets the
password to the default value, 0000.

The test password is not affected by this DIP switch.
Use the Reset Data screen to disable the test password.
SW1-2, Maintenance. The maintenance DIP switch
inhibits transfer. Use it to prevent transfers while
servicing the ATS. When this switch is in the ON
position, sensing, timing, engine start and contactor
functions are disabled. A preferred source failure will be
ignored. The Not in Auto LED flashes red and the
message Maintenance Mode is indicated on the LCD
screen. In addition, a programmable digital output is
turned on and an entry in the event log indicates that the
maintenance mode has been activated.
monitoring and setup are allowed while in maintenance
mode.
Switch SW1-2 should
maintenance or service. It must be OFF during
normal operation.
Close and lock the enclosure door before energizing the
transfer switch.
