Digital Switch Wiring
Each LiteKeeper 8® unit is capable of supporting the
Greengate Digital Switch (GDS) station. The GDS do not
wire directly to the LiteKeeper 8® logic board, but are wired
using a CAN Bus network that connects to the LiteKeeper
8® through a gateway called the GDS-I. GDS stations are
wired using the Eaton's Cooper Controls LCCP or LCCNP
cable, or Belden 1502P or 1502R equivallents.
For best network performance, one of the suggested
cables should be used. If the specified cable is not
used and communications problems occur that require
troubleshooting assistance, additional charges for support
may be assessed.
Digital Switch devices should be networked together in a
daisy chain configuration. No T-Taps/Stars should be used.
The GDS-I device should reside somewhere within the
daisy chain switch network. Total daisy chain network length
should not exceed 1000 feet.
The following instructions describe the GDS-I device
connection to the LiteKeeper 8®. Please refer to the
Greengate Digital Switch installation instructions for
information on wiring the Digital Switch Network to the
Digital Switch Gateway.
1.
Mount the GDS-I next to the LiteKeeper®-8 panel.
A six foot phone style cable has been provided for
connection to the LiteKeeper-8® panel.
2.
Run a length of the Digital Switch LC or Belden cabling
from the GDS-I location to the low voltage section of
the LiteKeeper 8®.
3.
Connect the RED wire in the cable to the +V terminal
on the back of the GDS-I and to the LiteKeeper 8® at
one of the switch input +24 VDC terminals.
4.
Connect the BLACK wire in the cable to the GND
terminal on the back of the GDS-I and to the LiteKeeper
8® remote power connector GND terminal.
5.
Tape back or cap the blue and white wires and shield
wire for the cable. They will not be used for connection
between the GDS-I and lighting controller.
6.
Locate the 6 foot phone style cable included in the
GDS-I box. Run this from the GDS-I into the low voltage
section of the LiteKeeper 8® enclosure plugging the
end with 9 pin head into the GDS-I. Plug the end the
RJ11 phone style plug into the LiteKeeper 8®.
7 .
It is recommended that power be removed from the
logic board when doing initial switch input wiring.

GDS-I Wiring
Applying Power
1.
Once the wiring is complete, make certain that the
enclosure is clean of any wire clippings and that no
fragments are lodged in the relay circuit boards.
2.
Ensure that there are no loose wires or exposed wires
that could short to other wires or components.
3.
Power-up the unit from the circuit breaker.
4.
Once power is applied to the unit, lighting loads may be
operated via the ALL ON/ AUTO/ ALL OFF switch
as necessary.
Manually Controlling Relays
The relays in the enclosure may be controlled before the
logic board is programmed by using the on-board, ALL OFF ,
AUTO, ALL ON switch. In the ALL ON position the relay
coils will be energized. In the ALL OFF position, the relay
coils will be de-energized. The middle, AUTO, position allows
the relays to be controlled by the individual relay switches or
from the logic controller.
System Reset and Clear Commands
Under certain circumstances, you may want to reset the
LiteKeeper 8®. There are two different types of reset
commands available in the LiteKeeper 8® system: a soft
reset command and a clear reset command.
