1. CONTROL UNIT
The control unit (see pg. 3) should be mounted in a manned area. Route sensor control
cable through conduit from the junction box to the control unit. Sensor control cables
enter the control unit through the output port only. The cables are wired as shown in the
appropriate drawing (see pg. 6). The control unit accepts any possible combination of L-
series sensors.
INPUT POWER HOOKUP
Input power requirements are:
85 – 125 VAC
16 Watts max
47 – 440 Hz
Input power cable should be wired in accordance with all pertinent electrical codes. This
cable should enter the control unit through the input power port only. The power is
hooked up to the power supply and wired as per control drawing. NOTE: EARTH
GROUND TERMINAL MUST BE CONNECTED.
1. REMOTE ANNUNCIATOR OPTION
Mount remote annunciator (see pg. 11) within audio / visual range of the filling operator.
NOTE: the remote must be outside of the HAZARDOUS AREA. Pull appropriate low
voltage wire from the remote to the control unit. See appropriate drawing for wiring
details. Run wires through output port. Connect color coded nuts.
2. SK-4 CONNECTOR SEALING KIT
Make all splices using SK-4 connector kit (supplied)

connector” at controller. Does the “red
Light” illuminate?
(YES) controller is functioning.
Proceed to step 2.
(NO) controller is not functioning
(consult factory).

connector. Concentrate on white, black
and shield wire inputs from sensors,
making sure no shorts are present. Re-
plug connector and press test button.
Does the “Red Li
g
ht” illuminate?
(YES) system is functioning
properly.
(NO) Proceed to step 3.

mis-wire (concentrating on white and
black wires from sensor). Correct
problem and press test button. Does the
“Red Li
g
ht” illuminate?
(YES) problem are in the wire
connections at splice
(NO) sensor is not functioning
properl
y
. Proceed to step 4.
4) Remove sensor from installation,
connect at controller, shroud from light
and press test button. Sensor head
(prism) is not exposed to any external
light (ie: sunlight, indoor light, ect.).
Does the “Red Li
g
ht” illuminate?

(submerged)
(YES) correct alarm condition.
(
NO
)
proceed to step 2.

connector concentrating on red, white,
black and shield wire inputs from
sensors. Make sure no open circuits
are present. Re-plug the connector and
press test. Does the “Red Light” stay
on?
(YES) proceed to step 3.
(NO) System is functioning
properly. Problem was in the wire
or connections.

to the black input at the connector.
Make sure all sensor wiring is
disconnected. Does the “Red Light” stay
on?
(YES) Controller is not
functioning properly (consult
factory)
(NO) Controller driver boards are
functioning properly. Proceed to
step 4.
4) Check DC voltage from red input to
black input. Is it 7.5 – 9V DC?
(YES) proceed to step 5
(NO) Controller is not functioning
properl
y
. Consult factor
y
.
5) Check splice at sensor for moisture or
mis-wire. Correct problem. Does the
“Red Light” stay on?
(YES) proceed to step 6.
(NO) If light goes off before
pressing test button and goes on
after pressing test button
System is functioning properly.
Problem was in the connection or
wire.
6) Connect sensor directly to controller.
Make sure sensor head is not exposed
to light during test. Does the “Red Light”
stay on?
(YES) Sensor is not functioning
properly (consult factory)
(NO) Problem is in the wire or
connections.
Horn does not
sound on controller
when the “TEST”
button is pressed.
1) Are any “Red Lights” illuminated on
controller?
(YES) Make sure at least one
input is not in alarm state. Then
proceed to step 2.
(
NO
)
proceed to step 2.
2) Shut down system for 30 seconds.
Turn system back on. Does horn sound
when hitting the “TEST” button?
(YES) Controller is functioning
properly.
(NO) Controller is not functioning
properl
y
. Proceed to step 3.
3) While holding the “TEST” button
down put a voltmeter on the positive and
negative on the back of the horn. Do
you get 13.8 volts +/- 1?
(YES) Your horn does not work.
Replace horn.
(NO) Your horn board is not
workin
