Electromagnetic Flowmeter Detector 2-47
2.7.2: Grounding the detector (Remote models)
The detector is grounded via the external grounding terminal.
CAUTION
Insufficient grounding can cause output fluctuations, instability of the zero point,
or output drift. Secure single point grounding with a grounding resistance of 100
W
or less is recommended.
To avoid damaging the detector, do not ground a welder to the detector.
Grounding resistance
100 or less
As short as possible

2.7.3: Installing the dedicated cable
The dedicated cable is used to connect the detector to the remote converter. It
transmits either the flow rate proportional signal or the excitation current.
