Versa-Sense II Electronic Leak Detector
To install the probe, first back-twist the cable
counterclockwise to avoid wire twist when the
probe is threaded clockwise into the 1/4" NPT
boss ports. Apply PTFE tape or a small amount of
thread sealant to the threads prior to insertion.
Probe Installation
The VERSA-SENSE II Electronic Leak Detector
consists of a modular control unit encased in a
watertight enclosure and two detection probes. All
of these items are wired together as noted on the
schematic illustration Figure A and Figure D.
The VERSA-SENSE II Electronic Leak Detector
senses pumped liquid entering the air chambers of
the pump and works on the principle of conduc-
tance. The probes are installed into the bottom
boss on the air chambers (E1, E4, E2, E3, and U2
pump models.) When the diaphragm fails, the
probe is exposed to the pumped liquid. This pro-
duces a low current change of 1.2 volts DC (<1 mil-
liamp) which signals the control unit. One of the two
indicator lights signal which diaphragm has failed,
and which air chamber has been contaminated by
pumped fluid.
To install the probe, first back-twist the cable
counterclockwise to avoid wire twist when the
probe is threaded clockwise into the 1/4" NPT
boss ports. Apply PTFE tape or a small amount of
thread sealant to the threads prior to insertion.

NOTE: The VERSA-SENSE II Leak Detector will
detect any moisture that pools at the bottom of
the air chamber. Air supplies with high moisture
content will deposit the moisture at the bottom
of the pump's inner chamber. This will cause
the probe to send false signals of diaphragm
rupture to the control unit. When the leak
detector is used to detect diaphragm failure it is
recommended that an air line dryer be installed
in the air line supply line to lessen the chance of
false signals.

Conductivity
The control unit can be easily wired to an audible
alarm or pump shutdown device. For example you
can connect the leak detector unit to a solenoid,
which can shut the air supply off to the pump, or
sound an alarm by routing the external device into
the leak detector unit. The wires can enter through
one of the three port holes in the leak detection unit.
The output connection terminal has 100 watt power
output and each chamber has independent connec-
tions. If combining the two chambers, a four wire
lead spliced before the external device would be
necessary (See output connection terminal Figure B.)
The leak detector probes work under the principle
of conductance. Not all pumped liquid is conduc-
tive. If the diaphragm fails, the pumped product will
conduct (complete the circuit) and signal the box
and the warning light will come on.
Sensitivity of the detector can be adjusted by the
adjusting knobs R5 and R6. (See Figure C.) These
adjustment knobs work independently for each side
(chamber). They can be moved with a small screw
driver. These sensitivity knobs are also important in
setting to detect conductance fluid at the sensitivi-
ty most required. The sensitivity range of the detec-
tor is adjustable from OHM (2,000 Micro MHO) to
100,000 OHM (10 Micro MHO).
When sensing low conductivity, turning the screws
clockwise increases probe sensitivity.

Conductive/Non-Conductive Switch Information
Note: Pumps containing driver fluid should be filled with
conductive or non-conductive fluid, depending on the fluid
pumped. The driver fluid should be opposite of the pumped
product in order to determine diaphragm failure and light
warning LED signal(s). This is adjusted inside the box in
the following manner:
SW1 DOWN (LED 1) = LED on w/presence of
conductive fluid and off w/absence of conductive fluid.
SW1 UP (LED 1) =LED on w/absence of conductive
fluid and off w/absence of conductive fluid.
— OR —
SW2 DOWN (LED 2) = LED on w/presence of
conductive fluid and off w/absence of conductive fluid.
SW2 UP (LED 2) = LED on w/absence of conductive
fluid and off w/absence of conductive fluid.
When sensing low conductivity, turning the
screws clockwise increases probe sensitivity.

WARNING
Hazardous voltage. This Leak
Detector is an electrical device. It should
be wired by only qualified, licensed
electricians. The cover should never be
removed except by authorized, licensed
electricians. Failure to heed this warning
may result in electric shock, personal
lasting injury or death.
Power shall be disconnected before
enclosure is opened.
Enclosure shall be closed before power
is restored.
Probe Installation
To install the probe, rst back-twist the cable counterclockwise to avoid wire twist when the probe is threaded
clockwise into the 1/2-20 UNF boss ports. Apply PTFE
tape or a small amount of thread sealant to the threads
prior to insertion.
