Making Wiring Connections
To make wiring connections from SmartPAC PRO Servo to your press control emergency-stop, top-
stop, and input check circuits, do the following:
1. Run the stop circuit and input check circuit wires to SmartPAC PRO Servo through flexible
liquid-tight conduit to the enclosure. Because SmartPAC PRO Servo is rated NEMA 12
(protected against dust and oil), you must use conduit of the same rating and make proper
connections to ensure that the enclosure is NEMA-12-protected.
2. Locate connector TB4 on the SmartPAC PRO Servo board (see Figure 2-7, page 37) and unplug
it from its socket. Connect the wires for the stop and input check circuits to TB4 pin locations, as
shown in Table 2-2, below, and Figure 4 at the end of the manual.

3. Plug the connector back into its socket. Double-check connections to make sure that you did not
wire the connector backwards.
4. Connect top-stop, E-stop, and input check circuit wires at the press control or other box into
which you are tying them.
NOTICE
Be sure to number all wires in a way consistent with your press’s electrical prints.
5. Make all the necessary conduit connections to ensure NEMA 12 protection.
Setting the Input Check Voltage Switch
To set voltage for the input check circuit, do the following:
1. Find the input check voltage switch, S101, on the SmartPAC PRO Servo board. It is located on
the right side of the board just to the left of the E-stop relays.
2. Place S101 in the Left or Right position, depending on the coil voltage of the dual safety valve.
For a coil voltage of 60-250V, the switch should be placed in the Left position (this is the factory
setting). For 12-60V coil voltage, set the switch to the Right setting (see Figure 2-12).
