According to experience, transmission of alarms is not yet functional during putting into service
(no telephone line laid 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 transmission of alarms, for example using a GSM modem via a mobile telephone
system. In standalone operation, or as an alternative to monitoring with system centre / store
computer / operator terminal, an available alarm contact on the controller must be used to
realise transmission of alarms via a telephone network.
For fire prevention reasons, a suitable device for shutting down the defrost heating in the
event of excessive temperatures (high temperature circuit breaker) must already be taken into
account during planning of the installation.
For further information about the CAN bus, see the manual “Basics and General Safety and
Connection Notes”.

scan is the only possibility to define the sensors to be monitored; see chapter Necessary and optional
.sensors, page 20
5.1.2 Restart - restart of the controller
For a restart, the device is restarted with all configured parameters and the CAN bus address set on the
decade switches and . A restart can be initiated using the following procedure:S1 S2
disconnection and reconnection of the power supply
5.2 Selection of the sensor type.
The case controller uses 2-wire NTC temperature sensors and 2-wire Pt1000 temperature sensors for the
regulation.

KGL Operating Manual – UA 412 S 2019-01-14 /20 122
The first 5 temperature sensors (1..5) be identical in their type and of the type NTC and can be adjusted must
using the parameter (menu 6-2-5, set to "L243" at the factory). The following NTC sensor types Sensor type
are supported:
L243 (K243) temperature range -50 .. 50 °C
(the sensor K243 can also be used instead of the sensor L243 as the characteristic curves of both
sensors are identical)
K277 temperature range -50 .. 50 °C
5K3A1 temperature range 0 .. 100 °C
The next 5 temperature sensors (6..10) be of the type PTC:must
Design as Pt1000
For details, see chapter For information Assignment of the analogue inputs for temperature sensors., page 72
about the dimensions of the sensors, see chapter Mechanical data of the temperature sensors L243 / 5K3A1,
.page 121
The sensors must be mounted carefully. If sensor cables are exclusively laid within the refrigerated
case to be monitored, and sources of interference (e.g. parallel power lines) are not anticipated, then
it is possible to dispense with shielding. Otherwise, interference in the sensor cables must be
prevented using suitable measures.
5.2.1 Necessary and optional sensors
Dependent on the controller type, there are necessary and optional temperature sensors for the case
controller. A sensor scan is performed automatically during the first start of the controller. The number of
scanned sensors can be checked in the menu (6-1) or with the LDSWin PC software. Thereby, not connected
sensors can be excluded from the monitoring for sensor failure.
