1.5.4 Control Panel

1.5.5 Water Chiller

A. Fill Port—Your engraver arrives with no prefilled antifreeze. Use this port for filling a lsaser-safe antifreeze or
distilled water.
B. Power Switch—Your water cooling system should always be on during use of the laser, but should be switched
off during draining, refilling, cleaning, repair, and other maintenance.
C. Control Panel—This panel can be used to fine-tune the chiller's operation.
D. Water Gauge—Maintain the cooling liquid level within the green "NORMAL" range at all times. You should
also use the clear gauge to confirm that the liquid remains clean, particularly during initial testing.
E. Cooling Fans—Although these two fans may not activate at all during brief or low intensity use, they come
online and help keep the circulating water or antifreeze cool during extended and high intensity operation. Be
sure that they are well ventilated and completely unobstructed during use.
F. Drain Port—Use this port to fully drain your system's antifreeze or distilled water.
A. Laser Key—This lock turns the laser power supply on and off, helping
ensure only approved operators can use your engraver.
B. Ammeter—This digital display shows the current being provided to the
laser tube in mA. The knob to its right is its master power control. It
should be turned completely clockwise to enable your software to use the
engraver's full power range.
C. Emergency Stop—This button immediately cuts all power to the engraver
but only leaves the chiller running in the event of an emergency. Rotate it
up before use and push it down between sessions.
D. Interlocks—These switches automatically cut power to the laser tube if
the protective cover is raised.
E. Digital Touchscreen—This is the main control panel for the laser.
