    11.0 Troubleshooting *** CAUTION *** PARTS MAY BE HOT. If unit was running allow time for cool down. Exercise care when touching internal optical parts. *** WARNING: HIGH VOLTAGE *** High voltage may be present in bulb terminal connections. Allow 2 minutes to bleed down capacitor voltage. *** CAUTION *** Disconnect power from system or unplug system from wall or VAC power source before connecting the footswitch adapter.
  • Page 51 Open circuit voltage (no bulb). Open circuit voltage should rise to approx. +2340 Vdc for a few seconds, and then drop to approx. +330 Vdc. If power supply blows fuses without a load, then power supply components, wiring or shorts may be the problem. Perform visual inspection of power supply components and wiring.
  • Page 52 Verify that the lightguide is properly pushed into the lightguide socket and that the ball plunger is in the detent groove. MAX unit safety system disallows shutter operation if no lightguide is sensed by interlock switch within nosepiece. Set the unit to "Manual" mode. Turn the power ON. With a DC voltmeter, verify 24 VDC are present on the harness side of the solenoid connector and the footswitch is depressed.
