CONTROLS & INSTRUMENTS
GENERAL – The Gardner Denver
Electra–Saver
compressor’s controls and motor are prewired for the
voltage and horsepower specified at the time of the or-
der. It is necessary only to connect the motor to the
customer mounted starter, connect the control box and
the starter to the power supply, connect the compres-
sor discharge air line to the shop air line, and connect
the coolers to the shop water line, if the package is wa-
ter cooled. A standard compressor package consists
of the compressor, oil reservoir, oil cooling system and
oil filter, motor, NEMA 12 control box, and controls as
described below.
This compressor features the programmable control,
which integrates all the control functions under micro-
processor control. Its functions include safety and shut-
down, compressor regulation, operator control, and ad-
visory/maintenance indicators. The keypad and
display provide the operator with a logical and easily
operated control of the compressor and indication of its
condition.
PROTECTIVE DEVICES, ADVISORIES AND SHUT-
DOWNS – The ”AUTO SENTRY–ES” will shut down
the unit following any fault detected in the following de-
vices. Following a shutdown, a message will be dis-
played to indicate the cause. The shutdown light will be
displayed to indicate the cause. The shutdown light will
be on if the cause still exists, or will flash if the cause
has been cleared. To resume operation, the cause of
the shutdown must be corrected and the controller re-
set by pressing the ”STOP/RESET” key.
Motor Protection Devices – Overload heaters are fur-
nished for the fan motor starter in the voltage range
specified. There are three (3) overloads of proper size
for the starter and its enclosure. When replacing or
changing overloads refer to the heater table glued in-
side the starter enclosure.
Main unit starter should be adequately fused and pro-
vided with overload heaters suitable for the application
to provide protection for the unit drive motor.
