Switch the unit OFF, remove all connections except the loop and power connections, turn all front panel controls to minimum and switch back ON. If the problem persists, contact Ampetronic for advice. COMPRESSION LEDs not illuminating: Check input connections. - Page 9 Due to insufficient LOOP CURRENT or excessive metal loss. May require a special loop design to achieve acceptable performance, contact Ampetronic for advice. Instability or high frequency noise 1) It is possible for the loop cable to become grounded under fault conditions, resulting in instability which may sound like high frequency noise, buzz or whistling.
- Page 10 The loop short to earth may only be completed when a person steps on the tape in the affected location, which can create significant difficulties when diagnosing the cause of fuse failure. Contact Ampetronic for further advice if a unit is suffering recurring but untraceable failure of the rear panel fuse.
