Unit Safeties

Unit Safeties are faults that cause all running compressors

to be shut down.

UNIT FAULT:

LOW AMBIENT TEMP

The low ambient temperature cut-out is a safety shutdown

designed to protect the unit from operating in low ambient

conditions. In the cooling mode if the outdoor ambient

temperature falls below the programmable cutout, the

unit will shut down. Restart can occur when temperature

rises 0.6ºF above the cut-off. In the heating mode, if the

outdoor ambient temperature falls below 14ºF or if the

unit is fitted with the two speed option and fan speed

inhibit is in effect 18ºF, the unit will shut down. Restart

can occur when temperature rises to above 16ºF, or if

the unit is fitted with the two speed option and fan speed

inhibit is in effect at 19.6ºF.

UNIT FAULT:

HIGH AMBIENT TEMP

In the heating mode, only a high ambient temperature

cut-out is a safety shutdown designed to protect the

unit from operating in high ambient conditions. In the

heating mode, if the outside ambient temperature rises

to 77ºF the unit will shut down. Restart can occur when

temperature falls to 73.4ºF.

UNIT FAULT:

LOW LIQUID TEMP

The low leaving chilled liquid temperature cut-out is

operative in the cooling mode only. This safety protects

the unit from a water heat exchanger freeze-up should

the chilled liquid temperature drop below the freeze

point in the cooling mode. This situation could occur

under low flow conditions or if the microprocessor

setpoint values are improperly programmed. Anytime

the leaving chilled liquid temperature (water or glycol)

drops below the cut-out point, the unit will shutdown.

Restart can occur when chilled liquid temperature rises

2°F above the cut-out.

UNIT FAULT:

115VAC UNDER VOLTAGE

The under voltage safety assures that the system is

not operated at voltages where malfunction of the

microprocessor could result in system damage. When the

110 Vac to the microprocessor drops below the limit, a

unit fault is initiated to safely shut down the unit. Restart

is allowed when the 110 Vac is within limits and the

anti-recycle timers have finished counting down, unless

MANUAL POWER FAIL RESTART is programmed

under the OPTION key. In this case the unit switch must

be set to OFF then back to ON to reset this trip.

Units With Optional Hydro Kit

Units with one pump indicates the manual motor starter

protecting the pump from short circuit or overload

conditions has tripped or been set to OFF. Setting the

device to ON will reset the trip.
Units with two pumps, duty and standby indicates that

both the manual motor starters protecting the pumps

from short circuit or overload conditions have tripped

or both have been set to OFF. Setting at least one of the

devices to ON will reset the trip.

UNIT FAULT:

PUMP FAIL MAKE FLOW

Units with one pump, after the 30 second stop to start

timer has timed out the Pump is started if there is

•  a Leaving Liquid Temperature Cutout, or
•  any of the compressors are running or
•  with the daily schedule not calling for a shutdown

with unit switch on and

• the remote stop/start input closed (terminals 13 &

51 on -XTBC1). If the flow switch does not close

within 10 seconds the unit locks out on UNIT

FAULT: PUMP FAIL MAKE FLOW and the

pump is stopped. Setting the unit switch to OFF

then back to ON will reset the trip.

Units with two pumps, duty and standby, after the 30

second stop to start timer has timed out the Pump is

started if there is a

• Leaving Liquid Temperature Cutout, or
• any of the compressors are running or with the

daily schedule not calling for a shutdown with

unit switch on and

• the remote stop/start input closed (terminals 13 &

51 on -XTBC1. If the flow switch does not close

within 10 seconds the running pump is stopped

and the standby pump is started. If in a further 10

seconds the flow switch does not close the unit

locks out on UNIT FAULT: PUMP FAIL MAKE

FLOW and the running pump is stopped. Setting

the unit switch to OFF then back to ON will reset

the trip. In attempting to clear this fault also check

that one of the manual motor starters protecting

the pumps has not tripped.
