is the optimum choice for any situation requiring the
precise control of a water level. It is ideal for automatically maintaining the
correct level in cooling towers, storage tanks, or process water applications.
Model WLC-9000 achieves control by the use of a
corrosion resistant probes that sense the water level and then in conjunction with
electronics and a microprocessor, provides signals that can be used to open/close
valves and other control or recording devices thus maintaining correct levels.

T
he unit is powered by either 110 VAC or
220 VAC 60 HZ 0.5 Amp. The input voltage is determined by
the option selected. If the 110 VAC option is selected, then the
input power wires are: one black and one white. If the 220 VAC
option is selected, then the two input power wires are both black.
The unit is rated for indoor or outdoor installation.
These power relays may be used to control valves, or
solenoids; but not motors. There are also low power SPST
relays whose contacts are rated at 50 VAC/DC 0.25 Amp.
that can be used as an additional indicator or to provide an
indication to an event recorder, computer or automation system.
The normal indicator on the unit is a green LED that is
a "power ON" indicator and is on whenever power is applied to
the unit. There are also other LED's that turns ON whenever
the relay contacts are closed. These indicate a very high
level condition, or a DRAIN I or DRAIN II condition and will
remain ON until the level changes to some other level.
See Table 1 for the LED functions associated with the
various models. The contact with the water is sensed by
electronics and the microprocessor then provides the
necessary control for the various outputs.
The parts supplied are:
1 - The Waterline Control CONTROLLER.
1 - Stainless steel probe assembly with 50 feet of wire.
2 - U bolts with nuts.
1 - Mounting bracket.
