Connecting Power Wiring
– 24 VDC Powered Units
ELECTRIC SHOCK HAZARD
•
Do not connect the DC power source until you are done with all other installation procedures.
•
Turn off and disconnect power from the machinery SmartPAC PRO Servo is connected to
before making any wiring connections. This includes power to the machine control and motor.
Failure to comply with these instructions could result in death or serious injury.
Run a +24V and return wire from a 24VDC, 2A power supply into the conduit on top of the enclosure
on the right side. Connect the +24V wire to TB2 Pin 257, and the return wire to TB2 pin 258.
Connecting Stop Circuits and Input Check Circuit
You need four wires to connect SmartPAC PRO Servo to your press control stop circuits, two for the
emergency-stop circuit and two for the top-stop circuit. You can wire these circuits at your press
control. Refer to your press control manual or other electrical prints.
You need two wires to connect to the input check circuit. These wires are connected in parallel with
one of the coils on the Dual Safety Valve that controls the clutch/brake. When the clutch is engaged,
12–250 VAC or VDC (50-60 Hz) must be present across terminals A and B, as shown in Figure 2-9.
The connection can be made inside the press control where the circuits to the valve relays are
connected. Refer to your press control manual and electrical prints. It does not matter which wire
goes to terminal A and which to terminal B.
