2.1 Disclaimer in the event of non-compliance
These operating instructions contain information on the commissioning, function, operation and maintenance
ofthecontrolsandoftheassociatedcomponents.
2.2 Personnel requirements, requirements on staff
Special technical knowledge is required for planning, programming, installation, putting into service and
maintenance work. This work may only be performed by skilled, specially trained personnel. The installation,
putting into service and maintenance personnel must have training that authorises them to perform
interventions in the system and the automation system. The planning and programming personnel must be
familiar with the safety concepts of automation technology. Working on electrical systems requires special
technical knowledge. Work on electrical systems may only be performed by instructed electrically skilled
persons or under the guidance or supervision of such persons. The applicable regulations (e.g. DIN EN 60204,
EN 50178, DGUV Regulation 3, DIN-VDE 0100/0113) must be observed. The operating personnel must be
instructed in how to handle the system / machine and the controller and must be familiar with the operating
instructions.
WARNING
Warning of damage to goods!
In our experience, the transmission of fault messages is not yet functional during the putting into
service (no internet connection, no telephone line installed, etc.). It is strongly recommended in such
cases to monitor the controller via the CAN bus using a system centre, a store computer or an operator
terminal and to enable the transmission of fault messages, for example using a GSM modem via a
mobile telephone system. In standalone operation, or as an alternative to monitoring via system
centre / store computer / operator terminal, an available alarm contact on the controller must be used
to enable the transmission of fault messages via a telephone network.

For more information, refer to E*LDS basics, safety instructions, CAN bus & Modbus.

Observance of these operating instructions is a prerequisite for safe and trouble-free operation.

2.5 Electrostatic-sensitive components and control components (ESD)
All electrostatic-sensitive components and control components (referred to as "ESD" below) are labelled with
the warning sign shown. Electrostatic charges arise from friction of insulating materials (e.g. floor covering,
items of clothing made of synthetic fibres etc.). Even small charges can result in damage to or destruction of
components. Such damage is not always immediately noticeable; in some cases, it does not lead to failure until
after a certain operating time.
2.5.1 ESD - Rules for handling and working
Transport and store ESDs only in the protective packaging provided.
Avoid materials that may produce electrostatic discharge, for example
Plastic containers and table tops
Synthetic fibre clothing
Plastic-soled shoes
Plastic file covers
Styrofoam packaging
Computer monitors, etc.
Preferably wear the following:
Cotton work clothes
ESD shoes with conductive soles or leather soles
Use the following:
Conductive flooring
ESD workstations equipped with suitable tools (grounded soldering guns, antistatic wrist straps, etc.)
Conductive ESD bags, conductive plastic containers, IC tubes or cartons lined with conductive foam
Containers and worktops made of wood, metal or conductive plastics or paper bags

3 System Design of UA 4xx E
Figure: UA 410 E AC - full configuration
3.1 Application
The use of the case controller UA 4xx E for electronic expansion valves provides decisive advantages thanks to
a reduced pressure difference between the high and low pressure sides, low superheat at the evaporator as
well as constant conditions for the goods and evaporator thanks to continuous regulation. The adaptive suction
pressure control generates further savings potential thanks to the load independent increase of the suction
pressure. A range of functions for cost and energy saving such as defrost on demand, latent heat utilisation,
intelligent fan control, enthalpy controlled frame heater and the continuous temperature control of the goods are
available with this case controller.
The case controller is suitable for control and monitoring in refrigerated cases and cold rooms for normal-
temperature refrigeration, low-temperature refrigeration (NT/LT), cascade controllers* or sub coolers*. The
appropriate controller type for multidecks, refrigerated counters, freezer islands, freezer rooms etc. can be set
easily using the DIP switches on the controller. The factory settings for the desired application that have been
tried and tested in practical use are then loaded.
The UA 4xx E case controller is available in the variants UA 401 E CC / UA 400 E CC / UA 410 E AC. The two
UA 400 E CC / UA 410 E AC case controllers support single-zone and two-zone operation. The UA 410 E AC
supports the controller types UK 100 E sub cooler and KR 160 E cascade controller. The UA 401 E CC variant
only supports one temperature zone.

In order to fully utilise its performance features, the case controller is typically connected to the CAN bus, using
which it communicates with further control and monitoring components across the entire network. Intelligent
data exchange with the following system components takes place via the CAN bus:
System centre / store computer: Archiving of the operating data and alarm and message management,
connection to LDSWin for analysis, configuration and evaluation
Pack controllers: Adaptive control in connection with the associated pack controller, consumer lock
(emergency function in the event of pack failure)
3.2 Hardware
The case controller is housed in a plastic casing for DIN rail mounting and does not require any further optional
extension modules. Up to 99 case controllers can be used in the E*LDS system. If required, a BT 300 x
Operator Interface and up to 4 BT 30 Temperature Displays can be connected. For the direct parametrisation of
the case controller via LDSWin, for carrying out a firmware update of the case controller or for the
parametrisation of system components via CAN bus using LDSWin, the controller can be connected to a
notebook or a PC via the USB port. The following diagram illustrates the system architecture of the UA 410 E
AC case controller (complete design):
