ELECTRICAL COnnECTIOnS
WMP104.
The WMP104 is battery-powered totally self-con-
tained and does not require any electrical connections.
WMP101.
A connector is provided on the outside of the
WMP101. If the output cable has been ordered, follow the
diagram below to make connections to it. To connect to the
meter, plug the connector in and hand tighten the retaining
threads. A cable with connector can also be ordered from
any Turck sensor dealer, part no. RK4.5T-6/S618 (6 meter
length) or equivalent. Follow the diagram to make connec-
tions. If you are using the pulse output, connect power
first and determine that the meter is working properly by
observing the display. Then connect the pulse output.
OPERATIOn
Grounding (WMP101).
For best performance, especially
in chemically noisy environments, the gray ground wire
and the bare drain wire should be connected together and
to a good earth ground as close to the meter as possible.
Metal pipe and fittings in contact with the fluid should also
be bonded to the same earth ground with corrosion-resis-
tant connections.
Display.
The display reads flow rate and accumulated to-
tal, in the units for which it was ordered. The top line is
total, the bottom line is rate, and indicators give the units
(ac-ft, GPM for instance.) Empty or partially-full pipe is au-
tomatically detected and is indicated by a reading of “
– EP – “.
Battery.
Estimated battery life is one to ten years depend-
ing on usage, application, and power options selected dur-
ing purchase. On the battery-powered WMP104 there is a
low-battery indicator (“low bat”) when the battery voltage
drops below a certain point. Batteries should be changed
within four weeks of the appearance of this indicator.
