• Altitude: ≤1000 m

• Protection: IP20 (for indoor cabinet use)

Safety Precautions

1. Power Off First: Disconnect all power (24 VDC & main AC) before handling; wait ≥3 minutes for discharge.

2. High Safety Risk: This board is a safety‑critical component; faulty installation may cause death/injury.

3. ESD Protection: Always use anti‑static gloves/wrist strap when touching the PCB.

4. No Live Wiring: Never connect/disconnect cables with power applied.

5. No Modification: Do not alter circuits or components; unauthorized changes void warranty and disable safety functions.

Installation Steps

1. Power Down & Lockout: Cut off 24 VDC and main power; lockout/tagout to prevent accidental re‑energization.

2. ESD Setup: Wear anti‑static gear.

3. Mounting: Insert PCB into standard slot in R‑J3IC/R‑30iA cabinet; tighten screws (0.5–0.8 N·m).

4. Wiring:

   • CN1: 24 VDC power (pin1=+24V, pin2=0V)

   • CN2: E‑stop input (dual channel, per robot wiring diagram)

   • CN3: Safety relay output (to servo drive/controller interlock)

5. Check & Power On: Verify all connectors are seated; restore power and test E‑stop function.

Compatibility

• Robot Controllers: R‑J3IC, R‑30iA series

• Robot Models: Arc Mate 120iB/120iC, M‑16iB, M‑20iA, etc. (matching R‑J3IC/R‑30iA)

• Safety Standard: Complies with ISO 10218‑1/2, ANSI/RIA R15.06

Maintenance

1. Visual Inspection: Quarterly check for burnt components, loose connectors, or discoloration.

2. Function Test: Monthly test E‑stop response (trigger E‑stop; confirm all axes stop immediately).

3. Cleaning: Use dry, soft cloth only; no liquid cleaners.

4. Connector Check: Every 6 months, inspect CN1/CN2/CN3 for corrosion or looseness.

Troubleshooting

1. E‑Stop Not Responding:

   • Check 24 VDC input (CN1 pins 1–2).

   • Verify E‑stop switch wiring (CN2 dual channel).

   • Reseat PCB and connectors.

2. False E‑Stop Trigger:

   • Check for loose signal cables or ground loops.

   • Inspect E‑stop switch for contact wear.

3. Safety Relay No Output:

   • Check relay contacts (CN3) for damage.

   • Verify PCB power and input signals.
