Wiring

CONNECTING SWITCHES TO INPUT TERMINALS:

Please note a difference between FLOWLINE powered level switches and mechanical reed switches. All
powered level switches (series LZ12, LU10, LP15, LP50 & LO10 series) will be wired with the Red wire to the
(+) terminal and the Black wire to the (-) terminal. FLOWLINE mechanical reed switches (series LV10, LV2_,
LV3_, LV4_, LH2_ & LH3_ series) will have a particular wiring based upon part number. See the illustration
below to indicate wiring for your switch.
Note: the Shield wire will be used only for long cable runs or where excessive electrical noise is present.
* LV10 series can be wired using the White and Black wires for NO operations or the Red and Black wires for
NC operations.

LED INDICATION:

Use LED's located above the input terminals to indicate whether the switch is in a wet or
dry state. With most switch configurations, an Amber LED indicates the sensor is in
contact with liquid (wet) and no LED indicates the sensor is out of the liquid (dry).
Note: Mechanical reed switches (LV10, LV20, LV30, LV40, LH20, LH30 series etc.) may
be wired in reverse so that Amber indicates a dry state and no LED indicates a wet state.

VAC POWER INPUT WIRING:

Observe the labeling on the LC10 & LC11 series
controller. The terminals for the power share the
same terminal block as the relay.
Note: Polarity does not matter with the AC input
terminal.

RELAY INPUT WIRING:

The relay is a single pole, double throw type rated at 250 Volts AC, 16A (12A CE
version). The two terminals, NO and NC (normally open and normally closed), will be
used in different applications.
Note: The relay contacts are true dry contacts. There is no voltage sourced within
the relay contacts.
Note: The "normal" state is when the relay coil is de-energized and the Red relay
LED is Off / de-energized.
