Electrical Data

Alarms

The microprocessor shall activate an audible and visual alarm in event of any of the following condi- tions:

•High Temperature

•Low Temperature

•High Humidity

•Low Humidity

•Short Cycle

•Compressor Overload (Optional)

•Main Fan Overload (Optional)

•Humidifier Problem

•High Head Pressure

•Change Filter

•Loss of Air Flow

•Low Suction Pressure

•Loss of Power

•Custom Alarm (#1 to #4)

Custom alarms are four customer accessible alarm inputs to be indicated on the front panel. Custom alarms can be identified with prepared (programmed) alarm labels for the following frequently used inputs:

•Water Under Floor

•Smoke Detected

•Standby GC Pump On

•Loss of Water Flow

•Standby Unit On

User-customized text can be entered for all four custom alarms. Each alarm (unit and custom) can be separately enabled or disabled, selected to activate the common alarm, and programmed for a time delay of 0 to 255 seconds.

Audible Alarm

The audible alarm shall annunciate any alarm that is enabled by the operator.

Common Alarm

A programmable common alarm shall be provided to interface user selected alarms with a remote alarm device.

Remote Monitoring

All alarms shall be communicated to the Liebert site monitoring system with the following informa- tion: date and time of occurrence, unit number, and present temperature and humidity.

Analog Inputs

The system shall include four customer accessible analog inputs for sensors provided by others. The analog inputs shall accept a 4 to 20 mA signal. The user shall be able to change the input to 0 to 5 VDC or 0 to 10 VDC if desired. The gains for each analog input shall be programmable from the front panel. The analog inputs shall be able to be monitored from the front panel.

Diagnostics

The control system and electronic circuitry shall be provided with self-diagnostics to aid in trouble- shooting. The microcontroller board shall be diagnosed and reported as pass/not pass. Control inputs shall be indicated as on or off at the front monitor panel.

Control outputs shall be able to be turned on or off from the front monitor panel without using jump- ers or a service terminal. Each control output shall be indicated by an LED on a circuit board.
