IMPORTANT!
Use the type plate to check if the delivered unit corresponds to your order.
In particular, for devices with electrical components, check to see if the correct power
supply voltage is specified.
Accessories:
Connection cable with moulded
M12x1 coupling socket.
M12x1 coupling socket as component.
1.2
Intended use
The magnetic inductive flow sensor VMZ must only be used for measuring and metering
liquids with a minimum conductivity of
20 μ
S/cm.
WARNING! No safety component!
The magnetic inductive flow sensor of the series VMZ is no safety component in accord-
ance with Directive 2006
-
42
-EC (Machine Directive).
Never use the VMZ as a safety component.
The operational safety of the device supplied is only guaranteed by intended use. The speci-
fied limits (
§ 9 "Technical data") may under no circumstances be exceeded.
Before installing the device, check that the wetted materials of the device are compatible
with the media being used (
§
9.2
"Materials table").
Measuring tube empty (or partially filled). / Conductivity too low.
The green LED may blink irregularly if the measuring tube of the VMZ is empty or par-
tially filled or if the conductivity of the fluid being used is too low. Random pulses will be
present at the output, but they do not represent an actual flow.
Ensure that the measuring tube of the VMZ is always completely filled (
§
4.1
"Installation instructions").
Ensure t
hat the conductivity of the fluid is at least 20
μS/cm.
1.3
Exclusion of liability
We accept no liability for any damage or malfunctions resulting from incorrect installation,
inappropriate use of the device or failure to follow the instructions in this operating manual.
