ELECTRICAL Step Five
Connecting switches to input terminals: Please note a difference between FLOWLINE flow switches. All flow
switches will be wired with the White wire to the (S) terminal. Models FT10 ‐ _ _ _ 5 and GT10 ‐ _ _ _ 5 will be
wired with the Green wire to the (‐) terminal). The Red and Black wires can be wired to either the (+) terminal
or (‐) terminal based upon switch polarity. 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.
Normally Closed Normally Open
Switch Cable: When installing a Flowline flow switch,
adjust the cable away from the printed circuit boards
in the controller body. Avoid breaking the seal
between the top of the level switch and the plastic
coated cable.
VAC Power Input Wiring: Observe the labeling on
the LC30 Series. 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, 16 Amps. The two
terminal NO and NC (normally open and normally
closed) will be used in different applications.
Remember that the "normal" state is when the relay
coil is de‐energized and the Red relay LED is Off / de‐
energized.
