NOTE: The oil pump test will not energize the oil pump if
cooler pressure is below −5 psig (−35 kPa).
When the test is finished, or the EXIT
softkey is pressed,
the test will be stopped and the Control Test menu will be
displayed. If a specific automated test procedure is not
completed, access the particular control test to test the func-
tion when ready. The Control Test menu is described as
follows:
Automated Tests As described above, a complete
control test.
PSIO Thermistors Check of all PSIO
thermistors only.
Options Thermistors Check of all options
boards thermistors.
Transducers Check of all transducers.
Guide Vane Actuator Check of the guide vane
operation.
Pumps Check operation of pump outputs,
either all pumps can be
activated, or individual pumps.
The test will also test
the associated input such as
flow or pressure.
Discrete Outputs Activation of all on/off
outputs or individually.
Pumpdown/Lockout Pumpdown prevents the low
refrigerant alarm during
evacuation so refrigerant
can be removed from the unit;
locks the compressor off; and
starts the water pumps.
Terminate Lockout To charge refrigerant and enable
the chiller to run after pumpdown
lockout.
High Altitude Locations — Recalibration of the pres-
sure transducers will be necessary as the machine was ini-
tially calibrated at sea level. Refer to the calibration proce-
dure in the Troubleshooting Guide section.
Charge Refrigerant into Machine
The transfer, addition, or removal of refrigerant in spring
isolated machines may place severe stress on external
piping if springs have not been blocked in both up and
down directions.
The 19EF machine will have the refrigerant shipped sepa-
rately, and a nitrogen holding charge of 15 psig (103 kPa) in
the machine. Evacuate the entire machine, and charge ma-
chine from refrigerant cylinders.

6. Pumps All pumps or individual pumps may be
activated:
Oil pump — Confirm pressure
Chilled water pump — Confirm flow
Condenser water pump — Confirm flow
7. Discrete Outputs All outputs or individual outputs may be
energized:
Hot gas bypass relay
Oil heater relay
Motor cooling relay
Tower fan relay
Alarm relay
8. Pumpdown/Lockout When using pumpdown/lockout,
observe freeze up precautions when remov-
ing charge:
Instructs operator as to which valves to close
and when
Starts chilled water and condenser water
pumps and confirms flows
Monitors — Evaporator pressure
Condenser pressure
Evaporator temperature
during pumpout
procedures
Turns pumps off after pumpdown
Locks out compressor
9. Terminate Lockout Starts pumps and monitors flows
Instructs operator as to which values to open
and when
Monitors — Evaporator pressure
Condenser pressure
Evaporator temperature dur-
ing charging process
Terminates compressor lockout
*During any of the tests that are not automated, an out-of-range reading will
have an asterisk (*) next to the reading and a message will be displayed.
