E. Contact Closure Input Wiring
(Emergency Shutoff Switch, Gas Detector)
Connect wires from remote shutoff switch and/or gas
detector to the contact closure input terminal block
“TB1” shown on pages 11 and 13.
Use 24 AWG
twisted and shielded wire, such as Belden 9501
or equivalent.
Input can be configured for either
normally open or normally closed contacts via the
remote input jumper setting, JP1, on the controller
mainboard shown on page 11 and 13. The controller
default setting is normally open since the supplied
emergency shutoff switch is a normally open switch.
This default setting will cause all attached valves to
close any time the input circuit is closed via switch or
gas detector relay. See more info on pages 16 & 17.
F.
Output Relay Wiring
The standard low voltage relay
output is rated at a maximum of
1 amp @ 24V AC/DC. After the
completion of an emergency
shutoff sequence, this relay will
close for approximately 3 seconds.
The relay can be wired as
Normally Open or Normally Closed
but cannot be configured as
latching.
Optional Relay Interface
Module (P/N 4500.05)
The optional
Relay
Interface
Module (RIM)
when ordered ,
takes the place
of the standard
low voltage
relay. The
Relay Interface
Module provides a dry contact (K1) rated 5A @
250VAC. Relays K2 and K3 on the Relay Interface
Module are not factory configured for use but can be
in the field if required. Contact factory for instructions.
G.
115 / 230 VAC Power
After the controller is mounted and all I/O
connections are made, connect wires for 115 / 230
VAC power. Connect 115 / 230
VAC wires to the terminal block
labeled “115/230VAC”,
“WHT” (L2, low side), “GRN” (G,
ground) and “BLK” (L1, high
side).
See drawing on page 13.
Conduit and fittings should be
rated NEMA 4X to maintain a
gas and liquid-tight seal for the
controller.
H.
Battery
The battery is included, but not pre-
installed in the Gemini controller.
Install battery inside controller,
securing with yellow bracket.
1. Connect the Red controller wire
to the positive terminal of the
battery. Connect the
Black
controller wire to the negative
terminal of the battery.
2. Press the microprocessor
RESET button on the mainboard
inside the controller to insure
initiation of the control program
(see board image on page 11 for
button location).
CAUTION
AC power must be OFF when connecting power
wires to controller. Do not apply AC power to
controller until battery has been connected.
CAUTION
Do not install unauthorized relays or other
devices inside the Gemini controller box. Doing
so may damage the controller and will void the
Warranty.
WARNING
i
Battery MUST be connected for system to
operate.
i
To protect system, always connect battery
first, then AC charging power. Always
disconnect AC charging power first, then
disconnect battery.
i i
Do not connect battery leads until AC power
is also available. This will prevent excessive
discharge of the battery which could damage
the battery.
i
If the polarity of the battery connection is
accidentally reversed, the circuit board will
be damaged.
WARNING
Do not apply any source of power to Input
Terminal Block TB1. Applying power to this
terminal block will damage the system.
