Tempest Nd:YAG Laser Operator’s Manual
22
The control panel is connected to the power supply through a 10 foot
detachable DB15 extension cable. The connectors on both the control
panel and the power supply are female DB-15. Connect the control
panel cable to the control panel and to the back of the power supply.
Secure the cable at both connectors by tightening the screws.
An interlock connector is supplied with the system and must be installed
before the system can be operated. The purpose of the interlock
connector is to provide a method of interlocking the operation of the
laser with a safety switch which may be installed on a laboratory door or
other location. See Figure 1-1 for the location of the interlock connector.
The laser operation is stopped when the interlock circuit has been tripped
by the internal or external interlock. The user must fix the situation that
tripped the interlock and restart the laser to begin operating again. The
flashlamp energy knob must be set to the minimum and the START
button must be pressed.
Prior to operating the laser, the cooling system must be filled with
deionized/distilled water. Remove the water fill cap on the front of the
power supply. Fill the reservoir with approximately 800 ml of
deionized/distilled water.
NOTE: Only fill the system with deionized or distilled water. Use of
any other water will damage the system and void the warranty.
Close the shutter on the laser head. Rotate the Flashlamp Voltage knob
to the minimum energy START position. Press the START/STDBY
button on the control panel to activate the pump. Add additional
deionized (distilled) water, approximately 400 ml, until the reservoir is at
least 75% full. The water level may be seen through the water level
window on the front of the power supply. Press the OFF button.
Replace the water fill cap. Note: The pump may require priming to
initiate water flow. This may be done by squeezing the WATER OUT
line on the back of the power supply to force some water into the pump.
If that does not work, then disconnect the water hose at the WATER
OUT connector and force water into the system from this connector on
the back of the power supply
