    • The internal interlock is a loop that travels through the light head, passing through the glass switch and two thermostats. This interlock is in series with the control circuit of the large relays in the power supply. When the interlock is opened, the relays will open and cut the power to the lamp terminals.

  • Page 92: Trigger Board

    Trigger Board A trigger board is provided in the light head to start the lamp. This board operates on demand by sensing the lamp voltage. This board can be heard when it is functioning, although the sound is faint. By turning the unit on and off, the sound can be compared during trigger and cool-down.
  • Page 93 capacitor we use will burn open if it begins to short. A swollen capacitor should be replaced, and the unit should be tested to see that the capacitor did not damage the high or medium relay. To test the unit’s ability to switch power levels, make a manual exposure, then switch between the power levels, noting the change in intensity.

  • Page 96: Shutter Switch

    Shutter Switch The switch provides shutter position information to the PC board. This switch is in the lamp end where the cable enters, inside the manifold cover. The cam is in the chamber with the shutter. A failure of the switch can cause the shutter to rotate continuously or erratically.

    C Turn the shutter only counterclockwise (looking from the motor end) or you may damage the shutter switch on the other end of the light. • Remove the chain from the sprocket with care to keep tension. The chain has shortened links and will separate if slackened. If the chain opens, attach an end to the sprocket with tape or wire and revolve the shutter.

  • Page 101: Lamp Head Blowers

    Lamp Head Blowers • The lamp head blowers are controlled by the printed circuit board to provide the correct cooling to the lamp. During warm-up, the blowers are off or run very slowly. At idle and during low exposure, the blowers vary in speed.

  • Page 102: Lamp Head Signals

    Lamp Head Signals Signals at the Terminal Strip (Cable to the Lamp Head) A great deal of information about the operation of the lamp may be found at the terminal strip, in the power supply that connects to the lamp head. The terminals are counted number 1 at the end where the cable begins, and wire number 18 is the last wire.
  • Page 103 rises it increases. As the lamp reaches temperature, the fans speed increases to regulate the lamp. At idle, this voltage is typically 45 - 90V~ and depends on the lamp age and ambient temperature. When an exposure at high power is initiated, the lamp voltage rises to the maximum. The voltage remains there after the lamp returns to low power, until the lamp temperature again stabilizes.

Printing Light Check List Check List for Printing Light Troubleshooting and Service C In order for this check list to be effective it must be followed step by step. 1) Disconnect the integrator/timer from the power supply. This will make sure that a faulty integrator or cable is not responsible for the malfunction and also eliminate a bad DIN socket on the p.c.board.

  • Page 117 8) Check capacitors and relay circuit by: The capacitors and relays are checked by watching the voltage changes that take place at the different intensity levels. If a capacitor is not in the circuit the voltage readings on input and output will be the same. If the capacitor is pulled into the circuit the input and output voltages will be hundreds of volts apart.
