Installation requirements
The LIMES analyser may only be used for determining the total hardness in water.
Changes to the electrical wiring and parameterisation may only be carried out by an
authorised and experienced specialist.
The installation to be monitored must fulfil the following conditions:
•
The maximum permissible load capacity of the relay outputs and the total power of the
system must not be exceeded by the connected load.
•
All inductive loads (valves, motors, contactors, transformers) in the system must be
equipped with suitable overvoltage protection (e.g., RC element, varistor, diode, etc.).
•
If there are external devices with a high mains interference level in the vicinity of the
control unit, these must be reduced with suitable measures, or appropriate external
interference suppression measures (mains filters) must be taken at the supply voltage
input of the control unit.
