With End of Stroke feedback, the End of stroke sensor detects when the diaphragm rod has reached the end of each stroke. This allows
closed loop control of the diaphragm pump, verifying each stroke is complete.
GENERAL DESCRIPTION
An ARO® diaphragm pump equipped with the ARO Leak Detec-
tion Sensor warns of a diaphragm failure by sensing the presence
of liquid in the air chamber of the pump. This system uses a liquid
sensor in each of the two air chambers which will send an output
signal when fluid is detected.
INSTALLATION AND WARNINGS
NOTE: ALL WIRING MUST COMPLY WITH ALL LOCAL AND / OR
NATIONAL ELECTRICAL CODES.
y
Electrical codes that apply must be strictly adhered to; failure to
do so may lead to shock hazard or serious injury.
y
Some local electrical codes may require the installation of rigid
conduit.
y
The Leak Detection Sensor components must be installed by a
qualified electrician in compliance with all national, state and
local codes and regulations to reduce the risk of electrical shock
or other serious injury during installation and operation.
y
ARO is not responsible for accidents resulting from improper
installation of components or hardware.
y
HAZARDOUS VOLTAGE
. Do not attempt any service without
disconnecting all electrical supply sources.
