APPLICATION
THE GM40 Multi-Volt Series Time Controls are
universal, electromechanical time switches which can
be eld congured for various power supply voltages.
The Voltage options include 120VAC, 208/240VAC and
277VAC-all within the same unit! Selection of the
desired supply voltage is easily achieved by selecting
the DIP to the corresponding input voltage as indicated
on the printed circuit board assembly (refer to “input
voltage DIP switch setting section on page 1). The
mechanism is mounted in a UL TYPE 3R outdoor
enclosure and has been designed for the control of
lighting, heating, air conditioning, pumps, motors, or
general electrical circuits in residential, commercial,
industrial and agricultural facilities. All GM40 models
are available as “Mechanism Only” (-M) for installation
in other enclosures or control panels.
SPECIFIERS GUIDE
Furnish and install an Intermatic GM40 Multi-Volt
Series 24 hour or (7 day) time switch with captive
trippers and quartz or synchronous drive. Input voltage
shall be 120, 208/240 or 277VAC selectable via simple
to set DIP switch. All units shall incorporate both SPDT
and DPDT contacts that shall be rated at 40A, 2 HP @
277V. To set the starting time and to provide time
indication, the unit shall have an authentic clock face
with hour and minute hands. LED indicators shall
provide Power and Status feedback. Enclosure shall be
UL TYPE 3R suitable for both indoor or outdoor
installation. Time Switch shall contain an OFF/AUTO/
ON manual override. For Carry-over: The time switch
shall have a quartz drive with 7 day reserve carry-over.
PROGRAMMING INSTRUCTIONS
SETTING THE TIME: Rotate the program dial
gradually clockwise until the day of the week (7 day)
and time of day on the outer dial is nearly aligned with
the triangle marker at 2 o’clock position. Then set time
to the minute by rotating minute hand clockwise.
CAUTION: Do not rotate dial or minute hand
counter-clockwise.
PROGRAMMING: The 24 hour model has trippers of
15 minute increments, and an AM/PM indication on the
outer dial. The 7 day model has trippers of 2 hour
increments. the outer dial shows the 7 days of the
week and AM/PM for each day. Push the captive
trippers outward for the time period(s) that the load is
to be on (Normally open contacts closed).
MANUAL OVERRIDE: With the manual switch in the
middle position, the GM40 is in automatic mode and
will switch at the programmed times. In the upper
position “I”, the load is permanently OFF.
BATTERY POWERED RESERVE
(Quartz Models):
In case of power failure, the built-in nickel-metal
hydride battery maintains the time of day for 7 days.
During power outage relays are de-energized.
The GM40 is the only electromechanical general purpose time switch that offers multi-voltage selection, SPDT and
DPDT contacts, 40 Amp rating, indoor and outdoor enclosure - all standard in one model.
