3.3 Installation of Sensors
3.3.1 Overview and Preparation
Figure 20: Flowsensor models
1. Check if the sensor contains the calibration tag (with
K-Factor
and
5 Calibration Values
) and
if the data corresponds to the values on the calibration sheet delivered with each sensor.
2. Please store the delivered calibration sheet or its data on a defined storage place in order to
be able to refer to it in case that the converter is exchanged and that the tag was removed.
3.3.2 Instructions for Electrical Installation
1. Attach the SMB connectors from the sensors to the converter
and verify that “IN”/“OUT”
labeling on the converter corresponds to the labeling on the sensor cables.
2. For sensor cable length variations the extension cables can be used (described in
).
Similar to the sensor cables, the pair of extension cables is
labeled accordingly with “IN” and
“OUT”. Screw together the two connector protection covers of the sensor (male) and the
extension cables (female) (see
) in order to achieve an IP-65 protection of the
connectors. Do not shorten the cables on-site as a special tool is needed to assemble the
SMB connectors.
3. Do not pull directly on the cable when disconnecting it from the converter. Use the end of the
SMB connector to pull it.
4. After start-up a Zeroing is recommended. Assure that the sensor is completely filled with the
acco
rding fluid, is free of bubbles and that zero flow is realized. Then push the “ZERO ADJ”
button on the converters for about three
seconds. During adjustment “0ADJ” appears on the
converter display.
