C3 Conductivity:
The leak detector probes work under the principle
of conductance. Not all pumped liquid is conductive,
such as when using this device with a spill contain-
ment type SANDPIPER pump. Ideally, if the pumped
product is conductive, then the driver fluid should be
non-conductive. The driver fluid must be compatible
with the driver diaphragm and be compatible with the
pumped product. If the pumping diaphragm fails, the
pumped product will conduct (complete the circuit)
and signal the box and the warning light will come
on. If the reverse is required, such as pumping non-
conductive fluid, the driver fluid should be conductive.
If this is the case, move the two switches located in
the cover marked SW1 and SW2, to the opposite
locations. (See the close-up Figure D).
Sensitivity of this detector can be adjusted by the
adjusting knobs R5 and R6. (See Figure D.) These
adjusting 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 sensitivity
most required. The sensitivity range of the detector
is adjustable from 500 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.
