3.1 Installation Requirements
The analyser shall be used only to determine a parameter in the process water.
A proper operation can only be guaranteed by use of indicators which were
tested and recommended by the manufacturer
Changes to the electrical connections and the programming should be carried
out only by an authorized specialist.
The controlled system must meet the following conditions:
● The maximum allowable load capacity of the switching outputs and the
overall performance of the system must not be exceeded by the connected
load (note phase angle for inductive loads).
● All inductive loads (valves, motors, contactors, transformers) of the plant
must be equipped with suitable suppressors (e.g. RC element, varistor,
diode, etc.)
● If the analyser could be influenced by external devices with high electro-
magnetic interference levels, these effects should be reduced by appropriate
measures. On the supply voltage input of the offending equipment
appropriate external interference suppression (line filter) have to be fitted.
3.2 Instruction for Installation
During the assembly of printed circuit boards, the following guidelines must be
followed:
● Upon actuation of the clamping lever, only apply the force required.
Screwless terminals are capable to receive one- and finely-stranded
conductors (without core pods) to 0.5 mm ² (in sensor and analog output
terminals) or 2.5 mm ² (all other terminals). Using wire sleeves according to
the manufacturer is not require (only in case of screwless terminals)
● Observe all applicable electrical installation work rules.
● Work on electrical equipment of the plant / machinery must be performed by
a qualified electrician!
