B.
Gemini™ Controller
Installation of the controller should be performed
by a professional electrician in accordance with
applicable electrical codes.
Mount Controller
The Gemini controller
enclosure is gasket
sealed and rated for
installation in a
corrosive chemical
environment. The
controller should be
rigidly mounted to a
wall or other
permanent structure
within the length of the
electrical cable and
convenient to the
cylinder or ton valve
and the actuator storage bracket. Installation of the
controller should be performed by an electrician in
accordance with applicable electrical codes.
Maximum distance from actuator to controller must
not exceed 17 ft (5.2m).
See Actuator Cable
Extension info on page 18.
The back of the
Gemini enclosure is
equipped with tapped
screw holes for
mounting tabs. The
tabs and attach
screws are taped to
the inside of the
enclosure door for
shipping. Attach tabs
to enclosure using
screws and tapped holes. Fasten the controller to a
wall or structure using the mounting tabs and proper
anchors for the material. The controller should be
mounted in a location which allows its status lights to
be easily viewed by operators when working on the
ton container or cylinder.
It is recommended that 115 / 230 VAC power to the
controller be supplied from a dedicated circuit with
disconnect switch. Wiring should be through rigid
PVC or liquid tight flexible PVC coated conduit.
Connections and terminations should only be made
in enclosures rated for the corrosive environment
encountered in chlorine facilities (NEMA 4X). All
controller entry fittings should be of the proper size
and type to insure the gas-tight integrity of the
enclosure is not broken at cable or conduit
entrances. Molex Woodhead MAX-LOC® or similar
fittings are preferred.
C. Actuator Storage Bracket
An actuator storage bracket is provided for each
actuator. Install bracket on a wall or other structure in
a location convenient to the cylinder or ton container
and within reach of the actuator cable. The bracket
helps prevent damage to the actuator and cable
when not in use and during tank or cylinder change.
D. Actuator Cable
The actuator is shipped
with an electrical cable
pre-wired to the actuator.
This cable cannot be
disconnected from the
actuator in the field. If
longer cable lengths are
necessary, see
acceptable method for
cable extension on page
18, and consult the factory.
Connect actuator cable to the
actuator terminal block inside the
Gemini Controller (
see image and
drawing on page 11 and 13). For
proper polarity, the actuator wire
color must match the color
labeled on the terminal.
Red =
positive, black = negative .
CAUTION
Do not connect AC power to the controller or
battery leads to battery terminals until instructed
to do so. All other connections should be
completed first. Connecting AC power to the
improper terminal block will damage the
controller.
