Connection Steps
- Mount the PL-PRO DMC securely in a standard 19-inch equipment rack.
- Connect the unit's 20 Amp power cord to a dedicated 20 Amp grounded AC wall outlet. Ensure the outlet is capable of supplying 20 Amps.
- With the PL-PRO DMC power switch in the OFF position, connect your electronic equipment to the rear panel AC outlets. Distribute your equipment across the isolated outlet banks as needed to minimize interference.
- For temporary connections, use the front panel outlets.
- If desired, connect an optional BNC gooseneck lamp to the BNC connector on the front or rear panel for rack illumination.
Operating Instructions
Powering On/Off
To power on the unit and connected equipment, press the main power switch on the front panel to the ON position. The digital display will illuminate, showing the incoming voltage and current draw. To power off, press the switch to the OFF position.
Monitoring Voltage and Current
The front panel digital display continuously monitors and shows the incoming AC line voltage and the total current being drawn by all connected equipment. This allows you to keep track of your power consumption and ensure stable operation.
Protection Indicators
- "Protection OK" Indicator: A green LED on the front panel indicates that the SMP surge protection is active and functioning correctly.
- "Extreme Voltage Shutdown" Indicator: A red LED (if present, or indicated on display) will illuminate if the incoming voltage is too high or too low, triggering the EVS circuit to shut down power to protect connected equipment. Power will be restored automatically once the voltage returns to a safe range.
Maintenance
The Furman PL-PRO DMC requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Disconnect the unit from the power source before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure that the ventilation openings are not blocked. Proper airflow is essential to prevent overheating.
- Circuit Breaker: If the circuit breaker trips, disconnect some equipment, then press the breaker button to reset it. If it continues to trip, consult the troubleshooting section.
- No User-Serviceable Parts: Do not attempt to open the unit or perform any internal repairs. Refer all servicing to qualified Furman service personnel.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No AC power; tripped circuit breaker; faulty power cord. | Check wall outlet; reset circuit breaker on unit; ensure power cord is securely connected. |
| "Protection OK" light is off. | Unit has absorbed a significant surge; internal protection circuit may be compromised. | Contact Furman service for inspection. The unit may still pass power, but surge protection is no longer active. |
| "Extreme Voltage Shutdown" light is on. | Incoming AC voltage is outside safe operating range. | Wait for voltage to stabilize. If problem persists, consult an electrician. |
| Noise or hum in audio equipment. | Ground loop; interference from other components. | Ensure all equipment is properly grounded; try connecting components to different isolated outlet banks. |
| Circuit breaker trips frequently. | Overload; faulty equipment connected. | Reduce total current draw by disconnecting some equipment; check connected equipment for faults. |
