• Chassis: All CardPak DC drive chassis (VS Series, MaxPak compatible)

Installation & Adjustment

Installation

1. De-energize the entire drive system.

2. Insert 0-49067 into a free CardPak slot; tighten front-panel screws.

3. Verify edge connectors are fully seated; check +5 VDC/±15 VDC bus power.

Calibration

1. Power on; confirm Power LED is ON.

2. Apply reference input; adjust Gain pot for target output amplitude.

3. Set input to zero; adjust Offset pot for 0 VDC output.

4. Test interlock thresholds; adjust Threshold pot for fault trigger points.

5. Lock potentiometers; validate loop stability under load.

Operation & Faults

• Normal: Power/Run LEDs ON; clean output signal; no fault triggers.

• Fault LED ON: Overvoltage, short circuit, thermal trip, or interlock activation (reset after clearing fault).

• No Output: Check bus power, wiring, on-board fuse, or input signal presence.
