6. Installation Instructions

1. Power Off: Shut down and lock out the SealPak rack power.

2. Insert Card: Slide 0-50005-R into an empty slot in the rack.

3. Secure: Tighten the front-panel locking screw to secure the card.

4. Connect Wiring:

   • Field I/O: Connect sensors/actuators to the terminal strip.

   • Backplane: Ensure proper seating for +5 VDC, ±15 VDC, and communication bus.

5. Power On: Restore power and verify the Power LED is ON.

7. Calibration & Setup

Analog Input Calibration

1. Apply a precise ±10 VDC signal to the input channel.

2. Adjust the corresponding trim pot on the card for accurate reading at the control card.

3. Repeat for all 4 analog input channels.

Analog Output Calibration

1. Connect a voltmeter to the output channel.

2. Set the control card to output ±10 VDC.

3. Adjust the trim pot for exactly ±10 VDC at the terminal.

4. Repeat for both analog output channels.

Digital I/O Check

1. Apply 24 VDC to each digital input; verify the corresponding LED lights.

2. Trigger each digital output; verify relay click and continuity across contacts.

8. Operation & Fault Diagnosis

Normal Operation

• Power LED: ON (indicates +5 VDC bus power is present)

• Channel LEDs: Reflect input/output status (analog: signal present; digital: ON/OFF)

• Fault LED: OFF

Fault Conditions

• Fault LED ON: Indicates overvoltage, short-circuit, or thermal overload.

  • Action: Power off, inspect wiring for shorts, check for overloaded outputs, reset after cooling.

• No Analog Input: Check field sensor wiring, input signal range, and on-board fuse.

• No Analog Output: Check control signal, output wiring, and load impedance.

• Digital Input Not Responding: Verify 24 VDC supply and input wiring.

• Digital Output Not Switching: Check relay contacts, load wiring, and power.

9. Safety & Maintenance

• Safety: Disconnect all power before servicing. High voltage may be present even after power-off.

• Maintenance: Inspect quarterly for loose connections, damaged wiring, or corrosion. Clean with dry compressed air only.

• Repair: This card is obsolete; contact Reliance Electric or authorized vendors for repair or replacement options.
