1 Safety instructions
The safety regulations, codes and notes contained in this section must definitely be observed and
complied with at all times. During repairs on the entire E*LDS system, the accident prevention regu­
lations and general safety instructions must be observed. Important information (safety instructions
and hazard warnings) are indicated by corresponding symbols (see page 1 of the chapter ”Conven­
tions”).
Follow these instructions in order to prevent accidents and danger to life and limb, as well as dam­
age to the E*LDS system.
Warning - hazardous electrical voltage!
Danger of electric shock!
Beware of external voltage at the digital inputs and outputs!
All device connections/plugs are only to be plugged in, unplugged and/or wired when off load .
S
This instruction manual is an integral part of the equipment. It must be kept in the proximity of the equipment
and must be stored for future use, so that it can be referred to when necessary. To avoid operating errors, the
operation instructions must always be kept available for operating and maintenance staff, see Chapter 1.2.
S
For safety reasons, the equipment must not be used for any application other than described in the manual
i.e. only for the intended use, see Chapter 1.3.
S
Before using the equipment, always check that its limits are suitable for the intended application.
S
Check that the electric power supply is correct for the equipment before connecting it to power.
S
When using uncoded plug connectors, it is possible to connect them so that there is a danger to life and limb!
If this cannot be ruled out, coded plug connectors must be used.
S
Specified ambient conditions (e.g. humidity and temperature limits) must be observed and complied with in
order to avoid malfunctioning (see Section “Specifications”).
S
Check correct wiring of the connections before switching on power to the equipment.
S
Never operate the equipment without its casing. Before opening the casing the equipment must be switched to
zero potential.
S
Note and observe maximum load on relay contacts (see Section “Specifications”).
S
Contact the supplier in any malfunction.
S
Note that all leads running to and from the controller- especially those of the CAN bus - must be shielded and
installed sufficiently clear of other leads carrying live power. Doing so will avoid faulty measurements and will
protect the equipment from external interference via the analog inputs.
Parallel connection of RC elements is recommended for applications in a critical environment.
1. According to experience, error message transmission is not yet fully functional during commis­
sioning (no telephone line laid etc.) In such cases it is urgently recommended to monitor the con­
troller via the CAN bus using a system centre, a store computer or an operator terminal, and enable
error message transmission e.g. using a GSM modem via a mobile telephone network. In stand
alone operation, or as an alternative to monitoring with the system centre / store computer / operator
terminal, an alarm contact on the controller must be used in order to realise error message transmis­
sion via a telephone network.
2. In the interests of fire prevention, allowance should be made at the time of planning the system
for a suitable shutdown device designed to operate in the event of excessive temperature on the
defrost heater (high-temperature cutout).
For further information on the CAN bus, see the operation instructions
