Advanced Microprocessor Controls Setup

3.0ADVANCED MICROPROCESSOR CONTROLS SETUP

The Advanced Microprocessor (AM) Control for your Liebert Deluxe unit features an easy to use menu driven LCD display. The menus, control features, and circuit board details are described in this section. For more control details refer to 5.0 - Response by Control Type—Advanced Micropro- cessor Controls, and for more alarm information refer to 6.0 - Alarm Descriptions and Solu- tions.

3.1Basics

Control keys include ON/OFF, MENU/ESCAPE, ENTER, Increase (UP) arrow, and Decrease (DOWN) arrow. Refer to Figure 1. These keys are used to move through the menus as prompted on the LCD display (refer to Figure 2).

To turn the unit on, press the ON/OFF key after power is applied. To turn the unit off, press the ON/ OFF key before power is disconnected.

Active alarms are displayed on the LCD screen. An audible beeper also annunciates alarms. To silence an alarm, press the ENTER key as prompted on the display. The unit stores the 10 most recent alarms for review.

Setpoints, DIP switch settings, and other selections were made on your unit before testing at the fac- tory. Setpoints were chosen based on typical operating experience. Other selections were made based on options included with your unit. Make adjustments to the factory default selections ONLY if they do not meet your specifications. When entering setpoints, time delays, etc., the allowable ranges are displayed and may require a password, if enabled.
