Switch-on phase

After switching on, the device first carries out a
self-check.
The current measured value is then output on
the signal cable.

Setup

6.1 Indication of the switching
status
The switching status of the electronics can be
checked via the 360° status indication (LEDs)
integrated in the upper part of the housing.
The colours of the 360° status indication have
the following meaning:
•
Green lights up - power supply connected,
sensor output high-impedance
•
Green flashing - Maintenance required
•
Yellow lights up - power supply connected,
sensor output low impedance
•
Red lights - shortcircuit or overload in the
load circuit (sensor output high-impedance)
•
Red flashing - Error at sensor or electronics
(sensor output high impedance) or device is
in simulation

Diagnostics and servicing

7.1

Maintenance

Maintenance
If the device is used properly, no special mainte-
nance is required in normal operation.
Cleaning
The cleaning helps that the type label and mar-
kings on the instrument are visible.
Take note of the following:
•
Use only cleaning agents which do not cor-
rode the housings, type label and seals
•
Use only cleaning methods corresponding
to the housing protection rating
7.2

Rectify faults

Reaction when malfunction occurs
The operator of the system is responsible for
taking suitable measures to rectify faults.
Causes of malfunction
The device offers maximum reliability. Never-
theless, faults can occur during operation.
These may be caused by the following, e.g.:
