Ransburg Evolver MicroPak Controller A10406 - Manual (Page 15)

INTERLOCKS AND I/O
Interlock and I/O connections are made to con-
nector P3 on the rear of the controller. P3 consists
of three, 8-position terminal blocks A, B, and C
(see Figure 3). To wire to these terminal blocks,
perform the following (see Figure 4):
1. Loosen the 2 screws of P3’s connector housing
and remove P3 from the controller.
2. Loosen the 4 screws holding the terminal block
assembly to the inside of the connector housing
and remove the terminal block assembly from
the housing.
3. Feed the I/O / Interlock cable(s) through the
cable grommet attached to the connector housing
and pull out the other side. It may be necessary
to remove the cable grommet to fit the cable(s)
through. If so, slide the grommet connections onto
the cable(s) in the order shown in Figure 4 before
pulling the cable through the connector housing.
† For maximum noise immunity, all wir-
ing should be run in cables having a foil
shield with an overall braided shield. The
foil shield provides 100% shielding, while
the braid provides a means of making
proper 360° shield terminations at the ca-
ble ends.
NOTE
If multiple I/O / Interlock cables are used,
connect the exposed 1.5” cable braids
together using copper tape.
NOTE
4. Strip the jacket off the cable(s) 3” from the
end and remove the braid 1.5” from the end (see
Figure 5).
5. Strip the individual cable wires, install appro-
priate wire ferrules, and connect to the terminal
blocks according to Table 1.
6. Rotate the connector housing to achieve de-
sired routing of the cable bundle (right or left),
then reinstall the terminal block assembly into the
connector housing.
7. Tighten the connector grommet ensuring the
grommet spring makes 360° contact with the
exposed cable braid/copper tape for maximum
noise immunity.
For maximum noise immunity, the shields of the I/O
and interlock cables should also be connected to
earth ground at the end opposite to the MicroPak
controller connections.
If it is necessary or desired to run the interlock and
I/O cable(s) through conduit, an adapter can be
readily purchased that converts the PG21 male
threads of the P3 connector housing to 3/4” NPT
male threads. This adapter is available through
McMaster-Carr as their Part Number 7842K7.
