IMPORTANT (NOTE)
An additional document with Ex safety instructions is available for measuring systems that are
used in explosion hazardous areas. As a result, it is crucial that the specifications and data it
lists are also observed.
6.1

Preliminary checks prior to start-up

The following points must be checked before commissioning:
• The supply power must be switched off.
• The supply power must match information on the name plate.
• The pin assignment must correspond to the connection diagram.
• Sensor and transmitter must be grounded properly.
• The temperature limits must be observed.
• The sensor must be installed at a largely vibration-free location.
• The housing cover and its safety locking device must be sealed before switching on the
supply power.
• For devices with remote mount design and an accuracy of 0.2 % of rate make sure that the
flowmeter sensor and the transmitter match correctly.
For this purpose, the final characters X1, X2, etc. are printed on the name plates of the
flowmeter sensors, whereas the transmitters are identified by the final characters Y1, Y2,
etc. Devices with the end characters X1 / Y1 or X2 / Y2, etc. fit with each other.

Operation

The LCD display is provided with capacitive control buttons. These enable you to control the
device through the glass of the closed cover.
IMPORTANT (NOTE)
The transmitter automatically calibrates the capacitive control buttons on a regular basis. If the
cover should be opened during operation, the buttons' sensitivity is at first increased. As a
result, operating errors may occur. The button sensitivity will return to normal during the next
automatic calibration.
