5. Connect the proper wiring/connector to the
CTR interface module.
The CTR interface module has two 16-
position, compression-type terminal blocks,
as shown in Figure 15-2. To connect a contact
lead wire to any position on the block, turn the
screw counterclockwise, slide the wire
beneath the spring, and then tighten the screw.
You may use up to 14 AWG stranded wire.
Using Figure 15-2 and Figure 15-3 as guides,
carefully connect the wiring for your applica-
tion. Note that each circuit involves two CTR
modules: one at the “sending” end and one at
the “receiving” end. For each circuit, connect
the leads from the contact for which the status
is to be transmitted to the two positions
assigned to that circuit on the terminal block
labeled “P2” (on the CTR interface module) at
the “sending” end. Next, connect the leads
from the device that is to receive the status to
the two positions assigned to the circuit on the
terminal block labeled “P1” at the “receiving”
end. Repeat this procedure for each circuit
you are connecting to this pair of CTR
modules. The inputs and outputs are not
polarity sensitive.
15.3.2 Software Settings
There are no configurable settings for the Contact
Transfer Module, except for the DS0 channel slot
assignments.
