Application of UA 300 D
2.1
Versions
The UA 300 D Case Controller is produced in different versions varying for networked or stand−alone operation
and mounting location:
- UA 300 D CC
- UA 300 D CS
- UA 300 D TC
- UA 300 D TS
- UA 300 D AC
- UA 300 D AS
For control of chiller and freezer coldrooms the UA 300 D CS/TS/AS is designed to install in a casing in the con-
trol panel or in the UA 300 D CC/TC cap rail casing on the mounting plate. A digital output (24 V DC / 50 mA) is
provided on the controller to connect an external signalling device.
Integration in CAN bus
Type UA 300 D CC / CS / AC / AS controllers are designed to integrated in the CAN bus of the new LDS Sy-
stem. The suffix CC stands for "CAN in Cabinet/DIN rail mounting" (CAN bus connection, controller installs in
display case, cap rail mounting). The suffix CS stands for "CAN in Switchbox" (CAN bus connection, controller
installs in system control panel).
The UA 300 D does not allow of disabling CAN refrigeration points by the compressor pack con-
troller.
Stand−alone operation
Type UA 300 D TC / TS / AC / AS controllers are designed for stand−alone operation independent of the LDS
System, meaning that the case or coldroom controller works on its own and is not connected to the CAN bus.
The suffix TC stands for "Timer in Cabinet/DIN rail mounting" (internal real−time clock, controller installs in dis-
play case, cap rail mounting). The suffix TS stands for "Timer in Switchbox" (internal real−time clock, controller
installs in control panel).
Type UA 300 D TC / TS / AC / AS controllers have an internal battery−backed real−time clock and internal data
recording memory. The clock continues running in any electric power failure.
All−in−one
The controllers UA 300 D AC/ AS have been developed for integration in the CAN bus and for stand−alone ope-
ration. The suffix AC stands for All in Cabinet/DIN rail mounting (controller installs in display case, cap rail moun-
ting), the suffix AS stands for All in Switchbox (controller installs in system control panel).
