Two sets of SPDT relay contacts are provided on the power supply board. None
of the relay contacts are powered. The user must supply the proper power to the
contacts. For applications that require the same switched operating voltage as
the Q45 (115 or 230 V), power may be jumpered from the power input terminals
at
TB5.
Relay wiring is connected at
TB3
as shown below. Note that the relay
contact markings are shown in the NORMAL mode. Programming a relay for
“Failsafe” operation reverses the NO and NC positions in this diagram.

Sensor Wiring
The sensor cable can be quickly connected to the Q45 terminal strip by matching
the wire colors on the cable to the color designations on the label in the monitor.
A junction box is also available to provide a break point for long sensor cable
runs. Route signal cable away from AC power lines, adjustable frequency drives,
motors, or other noisy electrical signal lines. Do not run sensor or signal cables
in conduit that contains AC power lines or motor leads.
WIRING NOTE
:
The cable for the optical D.O. sensor contains a “black” wire that is
actually a black shrink tube covering both a blue and a pink wire.
These two wires connect to the same point designated by black in
figure 4-1. If the cable is cut to a shorter length, be sure that both
wires are connected to the terminal marked black.
A yellow and a gray wire are contained in the cable and are
covered to avoid shorting. If the cable length is changed, do
not strip these two wires. If possible, leave sensor cable uncut
to avoid problems.
