Unit Description
34
Sixteen general purpose keys are used to enter and
scroll through the controller menu tree and
message text; initiate Pretrip and Function tests;
enter new setpoint temperature; and enter trip
information. The keyboard supports both
numerical and text input. Four special keys
provide quick access to set-point temperature
change, manual defrost initiation, alternate
return/supply air temperature display, and
alternate temperature scale (C/F) display.
Status indicator LEDs in the controller display
signal Compressor, Heat, Defrost, In-range,
Alarm, Humidity, Supply Temperature display
and Return Temperature display.
A datalogger incorporated in the controller
records sensor temperatures as well as loss of
power, alarms, unit operating modes, sensor
failure, setpoint change and unit shutdown
indications. All data recordings are stored in a
RAM memory that is backed by battery.
Logging intervals are selectable from 1 minute
and 1/2, 1, 2 or 4 hours. When a 1 hour logging
interval is selected, the datalogger memory can
store approximately 512 days of information on
MPC2000ID controller (680 days on MP-3000a
controller). The logging of USDA sensors is fixed
at 1 hour intervals to comply with USDA
requirements.
The datalogger clock is factory set at UTC time.
All data logs include the time and date; setpoint
temperature; and supply, return, USDA1, USDA2
and USDA3 sensor temperatures; plus humidity
and ambient sensors on MP-3000a. All
temperature logs can be viewed from the
controller’s LCD message display.
A high speed serial communication port provides
data retrieval using a DRU-II or SmartSponge
handheld data retriever, or a REFCON power line
remote monitoring system.
USDA Cold Treatment Temperature
Recording
The datalogger includes provisions for the use of
up to four USDA sensors. These sensors allow
temperatures in various areas of the load to be
monitored and recorded for United States
Department of Agriculture use in monitoring Cold
Treatment shipments.
Dehumidification System
A dehumidification system lowers the relative
humidity in the container to the humidity setpoint.
The setpoint is adjustable between 60% and 99%.
Humidification Control System
Option
An optional humidification system increases the
relative humidity in the container to the humidity
setpoint. The control range is between 60% and
99%.
REFCON Remote Monitoring
Modem (RMM)
A REFCON remote monitoring modem is
provided to permit remote monitoring via the
power cable. High speed transmission reads all
controller information. Data can also be retrieved
from the datalogger via high speed transmission.
Pressure Gauge Options
A high pressure gauge is available to indicate
condenser (high side) pressure. A low pressure
gauge is available to indicate compressor suction
(low side) pressure.
Water-Cooled Condenser-Receiver
Tank
A water-cooled condenser-receiver provides the
unit with above deck and below deck operating
capabilities. A Condenser Fan On/Off switch is
provided on the control box with the water-cooled
condenser option. Place the Condenser Fan
On/Off switch OFF for water-cooled condenser
operation.
