µP-T System Description (Rev. 04/03)

to a power outlet. Under these conditions, when the micro-

processor power switch is turned on and the

key is

pressed, the unit will start and run on diesel automatically.

CAUTION: Electric operation mode is not stored in

the controller if the microprocessor power switch is

turned O

. Turning the switch back O

again, even with

the power cord connected, will not assure start up in Elec-

tric Standby. If the voltage is low or an electric phase is

missing, the Electric icon will not be present in the display

and the unit will start in diesel.

Standard Model 50 Features

The following features are standard equipment on units

equipped with Electric Standby.

•

Automatic Diesel/Electric Selection—The unit will

automatically switch to electric operation when a

power cord is connected and the standby power is

switched ON.

•

Phase Lockout (Three Phase Units Only)—If the

motor rotation is reversed as a result of incorrect phase

rotation, the unit will shut down and generate an Alarm

Code 38. The phase rotation must be manually cor-

rected.

•

Remote Reset Solenoid—A remote reset solenoid is

provided to reset the overload relay.

•

Hot Gas Heat—Hot gas heat is utilized on standard

model 50 units.

Optional Model 50 Features

The following features are available as options on units

equipped with Electric Standby.

•

Automatic Phase Correction Option (Three Phase

Units Only) - The control system features two motor

contactors. This allows correct motor rotation regard-

less of phase rotation on the incoming power.

•

Electric Heat Option - The unit is equipped with a

heater contactor and electric evaporator heaters. These

heaters provide supplemental heat during electric mode

heat and defrost operation.
