Operating Instructions
Unit Controls
Unit Control Box
1. UNIT ON/OFF SWITCH.
a. ON position. Unit will operate on cool or
heat depending on the controller setpoint
temperature and the container air
temperature.
b. OFF position. The unit will not operate.
2. CONDENSER FAN SWITCH (Water-Cooled
Condenser Option)
.
a. FAN AIR position. Condenser fan
operates as required during cooling to
provide air-cooled condensing.
b. WATER position. Condenser fan does
NOT operate so refrigerant condensing
can be provided by the water-cooled
condenser.
NOTE: Water-cooled condenser requires a
water flow of 19 to 38 l/min. (5 to 10
gal./min.) when Condenser Fan On/Off
switch is OFF.
MPC2000ID or MP-3000a Controller
The MPC2000ID or MP-3000a microprocessor
controls all unit functions to maintain the cargo at
the proper temperature. The controller also
monitors and records system faults and performs
pre-trip.
1. KEYPAD. Sixteen general purpose keys are
used to display information, change the
setpoint, change programmable features and
initiate control tasks.
2. °C-°F KEY. Press this key to view
temperatures in the LED display in the
alternate temperature value. Alternate value
(C or F) shows while the key is pressed.
3. RET/SUP KEY. Press this key to view the
alternate sensor temperature in the LED
display. Alternate sensor (return or supply)
shows while the key is pressed.
4. DEFROST KEY. Press this key to initiate a
manual defrost cycle. If the evaporator coil
temperature is below 18 C (65 F), the unit will
defrost. Otherwise the controller will display
“Defrost Not Activated” in the LCD display
and the unit will continue normal operation.
5. SETPOINT KEY. Press this key to change the
setpoint. Cursor in the LCD display
automatically appears in the “TEMP SETP”
line of the Data menu. See “Changing the
Setpoint” in the Controller chapter for
complete instructions.
6. STATUS INDICATOR LEDs located in the
large LED display signal:
• Supply (Air Temperature)
• Return (Air Temperature)
• Humidity Mode (Humidification Option
set to On in Setpoint menu)
• Compressor (Cooling On)
• Heat (On)
• Defrost
• In-Range (Temperature)
• Alarm
The In-range LED illuminates when the
controlling air sensor temperature is less than
1.5 C (2.7 F) above set-point (standard). The
controller maintains the in-range signal during
defrost and after defrost for 60 minutes. If the
controlling air sensor temperature goes
out-of-range, the controller maintains the in-range
signal for 5 more minutes.
7. LED DISPLAY. Large red LED display shows
current control temperature during normal
operation. LED display also shows current test
state during a Pretrip (PTI) or Function test.
8. LCD DISPLAY. A 4-line LCD message
display shows setpoint during normal
operation. LCD display also shows controller
menu and unit operation information when
special keys are pressed.
