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 AutoSet processor board (see Figure 2-4, page 2-6 for
AutoSet 1500 or Figure 2-5, page 2-7 for AutoSet 1504). To make wiring connections, do the
following:
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; No. 14 wire may be required by local
codes.
2.
Determine how you will connect the wires from AutoSet to your press control stop circuit.
You need two wires. No. 16 wire is recommended; No. 14 wire may be required by local
codes. Wires should be connected to the top-stop circuit to prevent the press from sticking
on the bottom of its stroke when AutoSet stops the press due to an overload.
3.
Open the cover of the control enclosure and locate the 115V-230V voltage selector switch
(S110) in the upper right corner (see Figure 2-4 or Figure 2-5). It should be set to 115 V,
the factory setting. If your AutoSet will be used with 230 Vac, push the switch down to
the “230V” position, using your fingernail or a screwdriver.
4.
Run the power and stop circuit wires through flexible liquid-tight conduit to the enclosure.
The AutoSet enclosure is rated NEMA 12 (protected against dust and oil). You must use
conduit of the same rating and make proper connections to ensure NEMA 12 protection.
Wires go through the top right knockout. Leave a small service loop inside the enclosure.
ELECTRIC SHOCK HAZARD
• Do not connect the AC power source until you are done with all other installation procedures.
• Turn off and disconnect power from the machinery AutoSet 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.
Wintriss recommends that you connect AutoSet 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.
Remember that 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 AutoSet will stop the press.
