Commissioning

CAUTION
Risk of burns due to hot measuring media.
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
Before starting work on the device, make sure that it has
cooled sufficiently.
During commissioning of the flowmeter, observe the following
points:
— The ambient and operating conditions (pressure,
temperature, power supply) must correspond to the
details on the name plate and the specifications.
— Open the shut-off valves slowly in order to prevent
pressure surges that can damage the flowmeter.
— For liquid measurement media, vent the pipeline if
necessary.
— For devices with alarm signalling units, set these to the
required switching points.
7.1

Adjusting the alarm signalling unit

The alarm signalling unit is designed as a proximity switch.
When inserted in the proximity switch, the metal tag initiates
the switching process. The switching point can be adjusted
with a screwdriver.

1. Unscrew the housing cover.
2. Adjust the alarm setting to the required switching point
using a flat-bladed screwdriver.
3. Screw on housing cover.

Operating instructions

If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
