GUIDE TO CONTROLS

INSTALLATION

1. Power indicator:

This green LED lights when AC power is ON.

2. Relay indicator:

This red LED will light whenever the con-

troller energizes the relay, in response to the proper condition at
the sensor input(s) and after the time delay.

3. AC Power terminals:

Connection of 120 VAC power to the

controller. The setting may be changed to 240 VAC if desired.
This requires changing internal jumpers; this is covered in the
Installation section of the manual. Polarity (neutral and hot) does
not matter.

4. Relay terminals (NC, C, NO):

Connect the device you wish to

control (pump, alarm etc.) to these terminals: supply to the COM
terminal, and the device to the NO or NC terminal as required.
The switched device should be a noninductive load of not more
than 10 amps; for reactive loads the current must be derated or
protection circuits used. When the red LED is ON and the relay is
in the energized state, the NO terminal will be closed and the NC
terminal will be open.

5. Time delay:

Use potentiometer to set delay from 0.15 to 60 sec-

onds. Delay occurs during switch make and switch break .

6. Input indicators:

Use these LEDs for indicating Wet or Dry sta-

tus of switch. When switch is Wet, LED will be Amber. When
switch is dry, LED will either be Green for powered switches or
Off for reed switches. Note: Powered switches may be reversed
for Wet/Off, Dry/Amber indication.

7. Invert switch:

This switch reverses the logic of the relay control

in response to the switch(es): conditions that used to energize the
relay will now de-energize the relay and vice versa.

8. Latch switch (LC41 and LC42):

This switch determines how

the relay will be energized in response to the two sensor inputs.
When LATCH is OFF, the relay responds to sensor Input A only;
when LATCH is ON, the relay will energize or de-energize only
when both switches (A and B) are in the same condition (both wet
or both dry). The relay will remain latched until both switches
change conditions.

9. Input terminals:

Connect the switch wires to these terminals:

Note the polarity: (+) is a 13.5 VDC, 27 mA power supply (con-
nected to the red wire of a FLOWLINE level switch), and (-) is
the return path from the sensor (connected to the black wire of a
FLOWLINE level switch). If polarity is reversed, the sensors will
not work.

Panel DIN Rail Mounting

The controller may be mounted by either a back panel using two
screws through mounting holes located at the corners of the controller
or by snapping the controller on 35 mm DIN Rail.

Note: Always install the controller in a location where it does not
come into contact with liquid.

Connecting switches to input terminals:

Please note a difference between FLOWLINE powered level switches
and reed switches. All powered level switches (models LO10, LP10,
LP15, LP50, LU10, LZ12) will be wired with the Red wire to the (+)
terminal and the Black wire to the (-) terminal. FLOWLINE reed
switches (models LV10, LV20, LV30, LH20 and LH30) will have a par-
ticular 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.

LED Indication:

Use LED's located above the input terminals to indicate whether the
switch is in a wet or dry state. With powered switches, Green indi-
cates dry and Amber indicates wet. With reed switches, Amber indi-
cates wet and no LED indicates dry. Note: reed switches may be
wired in reverse so that wet indicates dry and Amber indicates dry.
