Use only as a guide. Pumping ranges are based on testing in nonturbulent conditions. Range may vary due to water temperature and
cable shape.
Note: As the tether length increases, so does the variance of the
pumping range.

P U L S A R p o i n t 800-50 Micro Master Pump Switch
Mechanically-activated, wide-angle switch designed for performance and reliability.
INSTALLATION
FIGURE A - Wiring Diagrams
Determine the pumping range for the installation (see Figures B and
C).
Do not tether less than 8 cm (3 inches) from the pipe.
APPLICATIONS
The Micro Master pump switch provides automatic control of pumps in
sump, sewage and non-potable water applications.
The Micro Master pump switch is not sensitive to rotation and can be
used in either calm or turbulent applications.
The SPDT version can be wired to work in either pump up (Normally
Closed) or pump down (Normally Open) applications.
Tighten the strap around the discharge pipe keeping the switch cable between the strap and the pipe to prevent slippage.
Space small ties at least 2.5 cm (1 inch) apart (see Figure D).
To re-adjust ties, press small tie tabs down.
To lock the releasable tab, run the remaining strap between the tab
and the head. Pull tightly
To eliminate any obstructions to the switch, tuck the strap back
through the head (see Figure D).
Wire switch as shown in Figure A.
Check installation.
Allow system to cycle to ensure proper operation.
