  If the red short/overload light is illuminated on your Clear-Com Power Supply, it indicates a short or overload on that channel, often due to a shorted or mis-wired cable or a defective remote station. To resolve this: * Remove cables one at a time until you locate the faulty line. * Check for shorts between pins #1 and #2. Once the short is removed, the PS-702 will automatically reset, and power will return within a few seconds. Also, check the remote station and replace it if necessary.

  If both red short/overload lights are illuminated on your Clear-Com Power Supply, it typically means the system is overloaded or there's a short in the multipair cable. To troubleshoot: * Remove cables one at a time to identify where the excess current is required. * Re-evaluate the system's current needs. Also, check for shorts between pins #1 and #2, removing cables one by one until you find the faulty line.

  If your Clear-Com Power Supply system isn't operating and there's no power to the PS-702, with neither the green power light nor any short/overload lights illuminated, the issue could be due to: * No AC power reaching the PS-702: Check the AC connection and cable, ensuring it's plugged into a dependable AC source. * An internal power supply failure: In this case, the unit requires servicing.

Why is there hum or buzz in my Clear-Com PS-702 Power Supply system?

  If you're experiencing hum or buzz in your Clear-Com Power Supply system, it could be due to inductive pickup from nearby power lines or transformers, or an open 10? chassis ground resistor. Try relocating the main or remote stations away from power lines or transformers. Additionally, check the DC resistance for 10? between the chassis and pin #1 of any intercom connector.
