Front Control Panel
The control panel on the front door of the Dionex ED50A contains the liquid
crystal display (LCD), the membrane keypad, and the actuator for the main power
switch. The electronics chassis, described in Section 2.3, is located behind the
front door.
Power Switches
The main power switch is on a bulkhead inside the electronics chassis (in the
front, left-hand corner). The actuator for the power switch is on the front door,
below the control panel (see Figure 2-1). The actuator functions only when the
front door is fully closed. When the door is open, press the main power switch to
turn the Dionex ED50A on and off.
