3.1 Application
The UA 410 L AC temperature recording controller is based on the UA 400 hardware and has been developed
for use as a temperature recording controller of up to 10 temperature measurement points. In addition to the
recording function, it is also possible to control and defrost the first five sensors, so that a total of five
refrigeration points can be regulated independently of each other. The UA 410 L AC can be used for
temperature recording in accordance with the EU DIN EN 12830 Directive. Here, the controller is integrated in
the E*LDS system but it also offers the redundant temperature recording required by the standard. In order to
fully utilise its performance features the controller is typically connected to the CAN bus, through which it
communicates with further control and monitoring components across the entire network. Via the CAN bus an
intelligent data exchange is carried out with the following system components:
•
System Centre / Store computer: Archiving of the operating data as well as alarm and message
management, Connection to E*LDSWin for analysis, configuration and evaluation
•
Pack controller: Data exchange between the E*LDS components
•
Refrigeration point controller: Data recording between the E*LDS components
A BT 300 x Operator Interface and one to four BT 30 Temperature Displays can be connected to the controller
when required. Electrical connections are described in Section – Pin and Terminal Assignments.
