Operating Instructions
Starting the Unit
3-5
NOTE: PASS or FAIL is recorded in the datalog-
ger memory and can be viewed through the con-
troller’s VIEW/LOG/PT1 submenu. For instruc-
tions on viewing the VIEW/LOG/PT1 submenu,
refer to “Viewing Information in the View Menu”
in the
µµ
P-D Controller chapter of this manual.
NOTE: Clear the Alarm codes ONLY after the
alarm codes are documented and problems
repaired. Clearing the codes erases them from
the display memory of the controller.
However, a permanent record of the alarm
codes remains stored in the datalogger memory
of the controller for retrieval via PC-PAC™ soft-
ware.
WARNING: Some unit malfunctions will cause an
Alarm and unit shutdown condition. When the
alarm codes are cleared, the unit will start auto-
matically.
6.
Allow the unit to operate in the cool mode for 30 minutes
before loading the container. This will remove residual
container heat and moisture, and pre-cool the container
interior.
7.
Enter trip ID information into the controller memory using
the PC-PAC™ software (see instructions of PC-PAC™
software).
8.
Set the fresh air vent to the desired air exchange rate.
NOTE: If Dehumidification is turned ON, the
fresh air vent should be closed.
9.
Optional: Operate the humidity system (see “Humidify
Mode” on page 4-39). Verify that the air compressor
operates and that water is drawn into the atomizing nozzle
and injected into the return air stream (see “Humidity
System” on page 7-7).
10. Install a new chart and prepare the recording thermometer
for temperature recording (if so equipped):
• Wind the chart drive on the recording thermometer
(Partlow recorders).
• Check the battery charge on the recording thermometer
(Saginomiya recorders).
11. Stop the unit by moving the On/Off switch to the OFF
position.
Starting the Unit and Adjusting the
Controller Setpoint
CAUTION: Supply power connections from the unit
to the power source must always be made with the
refrigeration Unit On/Off switch and power supply
On/Off switch in the OFF positions. Never attempt to
start or stop the refrigeration unit with the unit power
cable.
1.
Connect the unit power cord to proper power source:
• 460/380V power cord to 460/380V, 60-50 Hz power
source.
• For operation on 230/190V power, insert the 460/380V
power plug into the dual voltage transformer receptacle.
Then connect the 230/190V power cord to a 230/190V,
60-50 Hz power source.
• Turn the power supply On/Off switch ON.
2.
Turn the unit On/Off switch to ON position. Check for
condenser fan and evaporator fan motor operation (see
“Condenser Fan and Evaporator Fan Rotation” in the
Electrical Maintenance chapter of this manual). If the unit
was properly pretripped, correct condenser fan rotation
will also indicate correct evaporator fan rotation.
3.
Adjust controller setpoint to the desired temperature:
• Press the UP or DOWN arrow key to increase or
decrease the setpoint. The left display flashes “SETPT”
while the right display shows the temperature.
• Wait four seconds for all three digits to appear on the
right display. Make additional setpoint adjustment if
necessary.
• Press the ENTER key when the desired setpoint shows
in the right display. The right display briefly shows
LOAD”. The controller then returns to the Standard
Display (showing new setpoint).
NOTE: If the ENTER key is not pressed within 10
seconds, the controller will default (return) to the
previous setpoint. If this occurs, repeat step 3.
