2.6 Control Panel
Details of the standard cabinet are explained below. Questions on customized cab-
inets should be referred to the manual issued by the machine manufacturer.
Follow the steps below for routine daily maintenance of the control panel.
1. Inspect the door(s) daily to ensure tight closure. The control panel is con-
structed as a dust-proof, sheet-steel enclosure with gasketed doors to keep out
dust and oil mists. Keep the door(s) tightly closed at all times.
2. Following inspection of the control with the door open, close the door and fas-
ten the door locks (two per door) securely using the key provided (Number
YE001). When opening (counter-clockwise rotation) or closing (clockwise
rotation), insert the key all the way into the keyhole and turn until it clicks
(approximately a quarter-turn). The key can be removed from an open or
closed position.
Note: If the optional door interlocking switch is provided, opening the door shuts
off the main power supply and stops all operations.
The following monthly maintenance must be performed.
1. Inspect the gaskets on the rims of the front and rear doors for openings or dam-
age.
2. Inspect the inside of the enclosure; clean it if necessary.
3. Look for any opening in the door base when the doors are tightly shut.
