Detailed Schematic Example
n
The schematic shows an 8-relay LitePak installation that utilizes
all of the options possible. In addition, the switching groups are
altered slightly from the standard factory connections to illustrate
grouping several relays on an output.
n
Relays 1,2,3 and 4 of the main panel are the factory connections.
Relays 5,6,7 and 8 of the main panel are all connected to
controller output #5 and they switch together.
n
The expansion panel has 3 groups of relays that are switched by
controller outputs #1, #2 and #6. Note that 11 conductors connect
the expansion panel to the main panel even though all conductors
are not used. This permits all possible switching combinations and
permits switch stations to be connected to the expansion panel.
n
The WPS-5527K photo sensor connects with 2 wires to the controller.
n
The primary connection of the transformer (wiring not shown) is
wired for a 277V connection. If connecting 120V, connect the
120V wire of the transformer to the terminal block.
Caution: Do not connect 277V to the 120V wire of the transformer
as the over voltage will damage the LitePak controller.
