Time Delays
Engine Start
(If emergency source is a generator set).
ON LED indicates that engine-start time delay is timing.
END LED indicates that the engine has been signaled to
start.
Normal to Emergency.
ON LED indicates that the
normal-to-emergency time delay is timing. END LED
indicates that the time delay has completed timing.
Emergency to Normal.
ON LED indicates that the
emergency to normal time delay is timing. END LED
indicates that the time delay has completed timing.
Engine Cooldown.
ON LED indicates that the
generator set engine cooldown timer is timing. END
LED illuminates until the engine has shut down.
Off Position.
ON LED indicates that the time delay off
position is timing. END LED indicates that the time delay
has completed timing.
Accessory Active
Plant Exerciser.
Plant excerciser LED indicates that
the system is in the exerciser mode.
Load Shed.
Load shed LED indicates that programmed
load shedding is active.
Inphase Monitor
(available on ZC type power switches
only). Inphase monitor LED indicates that the sources
are being monitored for phase relationship to allow
inphase transfer. The inphase monitor will permit
transfer from emergency to normal and normal to
emergency when sources are near synchronization.
NOTE
When a programmed transition switch is ordered, the
inphase
monitor
option
is
disabled
by
the
microprocessor.
Area Protection.
Area protection LED indicates that
the controller is in the area protection mode. The
generator will be signaled to START and the contactor
will transfer to the emergency position and remain there
while in area protection.
Programming Mode Switch
NOTE
The programming mode switch keys should be kept in a
safe place to prevent unwanted tampering with the
transfer switch control. Do
not
leave the programming
switch in the LOCAL position with the transfer switch
unattended.
Remote.
Allows both status monitoring and setting of
the transfer switch controls by a connected personal
computer.
Off.
Transfer switch status settings and power source
may be monitored from the local LCD display or
connected computers.
Local.
Allows both status monitoring and setting of
transfer switch control from the microprocessor’s LCD
display and keypad.
Control Switches
Test Switch (Standard).
Move the test switch to the
TEST position to simulate a normal source outage.
Not-in-Automatic system status light will flash.
Bypass N-E Time Delay Pushbutton Switch
(Option).
If the bypass normal-to-emergency time
delay
pushbutton
is
pressed
when
normal-to-emergency time delay is on, time delay will
end.
Bypass E-N Time Delay Pushbutton Switch
(Option).
If the bypass normal-to-emergency time
delay
pushbutton
is
pressed,
when
emergency-to-normal time delay is on, time delay will
end.
Manual Transfer to Emergency Switch (Option).
When the transfer switch control is in the manual mode
of operation and manual to emergency is required,
press the manual transfer-to-emergency pushbutton to
cause the transfer switch to transfer to the emergency
position.
Manual Transfer to Off Switch (Option).
When the
transfer switch control is in the manual mode of
operation and manual to off is required, press the
manual transfer-to-emergency pushbutton to cause the
transfer switch to transfer to the off position.
Manual Transfer to Normal Switch (Option).
When
the transfer switch control is in the manual mode of
operation and manual to normal is required, press the
manual transfer-to-emergency pushbutton to cause the
transfer switch to transfer to the normal position.
Auto/Inhibit Switch (Option).
If the auto/inhibit switch
is in the AUTO position, the transfer switch will operate
normally. If the switch is in the Inhibit position, the
transfer switch will not transfer under any conditions.
