Brief Description
WARNING
Do
not
attempt
to
service
the
Controller/DataCORDER
module.
Breaking the warranty seal will void the
warranty.
CAUTION
Remove
the
Controller/DataCORDER
module and unplug all wire harness
connectors before performing any arc
welding on any part of the container.
Do not remove wire harnesses from module
unless you are grounded to the unit frame
with a static safe wrist strap.
The
Carrier
Transicold
Micro-Link
2i
Controller/DataCORDER
is
a custom-designed
microprocessor-based module which incorporates
embedded software to:
a. Control supply or return air temperature to
extremely tight limits by providing modulated
refrigeration control, electric heat control and
defrost to ensure continuous conditioned air
delivery to the load.
b. Provide dual independent readouts of set point and
supply or return air temperatures.
c. Provide digital readout and ability to select data.
Refer to Table 3-3 for Controller Function Codes.
For Controller alarm digital display identification
refer to Table 3-4.
d. Provide a pre-trip step-by-step checkout of
refrigeration unit performance including: proper
component operation, electronic and refrigeration
control operation, heater operation, probe
calibration, pressure limiting and current limiting.
Refer to section 3.2.
e. Provide the ability to select or change Codes 27 to
37 and set point without AC power being hooked
up. Refer to section 3.1.4.
f. Provide reprogrammability and configuration
through a memory card. The memory card
automatically downloads new software to the
Controller when inserted, and controls output to the
display for status information.
g. Provide electronic data storage.
NOTE
For the benefit of the reader the remaining parts
of section 3.1 will devote themselves to the
temperature controller portion of the module.
For the integrated DataCORDER refer to
section 3.3.
