• CN2: Main contactor coil output

• CN3: Emergency stop / safety interlock input

• CN4: Auxiliary power distribution output

4. LED Indicators

• PWR (Green): ON when 24 VDC supply is normal

• ON (Green): ON when main contactor is energized (closed)

• ALM (Red): ON for fuse blow, E-stop circuit open, or relay coil fault

5. Installation Instructions

1. Power OFF the controller; wait 5 minutes for internal capacitors to discharge.

2. Wear an anti-static wristband to prevent ESD damage.

3. Insert the board into the designated cabinet slot; secure with 4 × M3 screws.

4. Connect CN1–CN4 per the cabinet wiring diagram.

5. Power ON the controller; verify: PWR = ON, ON = ON, ALM = OFF.

6. Safety & Protection Features

• Dual 5 A fuses: Overcurrent protection for control circuits

• E-stop interlock: Complies with Safety Category 3

• Relay isolation: Electrical separation between low-voltage control and power circuits

• Fault alarm: ALM signal sent to controller for diagnostic logging

7. Maintenance & Troubleshooting

7.1 Maintenance Schedule

• Quarterly: Check connector tightness and fuse condition.

• Annually: Clean dust with low-pressure dry air; inspect relay contacts for wear.

7.2 Troubleshooting

• PWR OFF: Check 24 VDC supply and CN1 wiring.

• ALM ON: Check 5 A fuses, E-stop circuit continuity, and relay coil.

• ON OFF (PWR ON): Check main contactor coil and CN2 connections.

• Intermittent operation: Inspect connector pins and relay contacts for corrosion.

8. Ordering & Warranty
