Chapter 2 Installation
Connecting AC and Stop Circuit Wiring
Wiring connections for AC power and stop circuits are made on terminal block TB103, which is
located at the upper right of the AutoSetPAC processor board (see Figure 2-6, page 37, or Figure 2-7,
page 38). To make wiring connections, do the following:
ELECTRIC SHOCK HAZARD
•
Do not connect the AC power source until you complete all other installation procedures.
•
Turn off and disconnect power from the machinery AutoSetPAC 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.
NOTICE
24 VDC VERSION WIRING DIAGRAMS
If you have the 24 Vdc version AutoSetPAC, follow the instructions in the appropriate wiring
diagrams at the end of this manual: Figures 6 and 7 for SmartPAC 2 or Figures 11 and 12 for
SmartPAC PRO.
1.
Determine how you will bring wiring from your 115 or 230 Vac power source to the control
enclosure. For 115 Vac, you need three wires—black (High), white (Neutral), and green
(Ground). For 230 Vac, wires are black (High), red (Neutral), and green or green/yellow
(Ground). No. 16 wire is recommended; use No. 14 if local codes require it.
NOTICE
AutoSetPAC must be wired into the stop circuit on the press. Otherwise, SmartPAC cannot stop
the press if AutoSetPAC detects a tonnage fault.
Wintriss recommends you connect AutoSetPAC to the top-stop rather than to the E-stop circuit of
your press to prevent the press from sticking on the bottom if an overload occurs.
Top-stop circuits are active only in Continuous (automatic) operations on most press controls. If
overload protection is required during Inch or Single-stroke mode, you may have to install an
additional relay so that AutoSetPAC can stop the press.
2.
Determine how you will connect the wires from AutoSetPAC to your press control stop circuit.
You need two wires. No. 16 is recommended; use No. 14 if local codes require it. Wires should
be connected to the top-stop circuit to prevent the press from sticking on the bottom of its stroke
when AutoSetPAC stops the press due to an overload.
3.
Open the control enclosure or console and locate the 115V-230V voltage selector switch (S110)
in the upper right corner of the AutoSetPAC processor board (see Figure 2-6 or Figure 2-7). Set
the switch to 115 V, the factory setting. If your AutoSetPAC will be used with 230 Vac, push the
switch to the “230V” position, using a fingernail or a screwdriver.
4.
Run the power and stop circuit wires through flexible liquid tight conduit to AutoSetPAC. If you
have an enclosure, it is rated NEMA 12 (protected against dust and oil). Use conduit of the same
rating and make proper connections to ensure NEMA 12 protection. Wires go through top right
knockout. Leave a small service loop inside the enclosure.
