GENERAL DESCRIPTION
Revision Level
This manual is supplemental information for the electronic
interface options on the PE series of pumps. For complete
pump installation, disassembly and reassembly, safety infor-
mation, and other general pump information, please refer to
the PD pump manual that was also included with the pump.
This electronic interface includes options for solenoid control,
end of stroke feedback, leak detection (diaphragm failure),
cycle counting on the major valve, and a ported motor with
no major valve for user-supplied control directly to the two
diaphragm air chambers.
Specialty Code 1 (Blank if no Speciality Code
)
A - Solenoid 120VAC
B - Solenoid 12VDC
C - Solenoid 240VAC
D - Solenoid 24VDC
G - Solenoid 12VDC ATEX
H -
Solenoid 24VDC ATEX
K - Solenoid 220VAC ATEX
N - Solenoid with no coil
P - Ported Motor (no major valve provided)
S - Cycle Sensing on Major Valve
0 -
Standard Valve Block ( No Solenoid)
Solenoid control allows the cycle rate of the pump to be con-
trolled electronically.
Specialty Code 2 (Blank if no Speciality Code
)
E - End of stroke feedback + Leak Detection
F - End of stroke feedback
L - Leak Detection
With Solenoid control, when the solenoid is energized, the
pump strokes and dispenses the fluid in one chamber. When
the solenoid is de-energized, the pump strokes in the oppo-
site direction, dispensing the fluid in the other chamber.
By providing continuous ON - OFF signals to the solenoid, the
fluid transfer rate may be increased or decreased remotely.
End of stroke feedback can be used in conjunction with the
solenoid valve to cycle the pump based upon completion of
each stroke.
0 - No Option
Special Testing
Testing for special testing options, please contact your
nearest ARO Customer Service Representative or Distributor.
The leak detection option incorporates an optical fluid sensor
in each air chamber to provide a signal when a diaphragm
has failed and fluid is leaking through the pump.
The cycle counter option provides a closed contact output
each time the pump completes a cycle. This option is not
available combined with solenoid control.
The ported motor with no major valve is provided as an op-
tion for users who want to supply compressed air directly to
each diaphragm and control the operation of the pump with
their own external air controls

SOLENOID
GENERAL DESCRIPTION
Without end of stroke feedback, solenoid control can only
be used to cycle the pump based on timing. The following
curves represent the flow rates of a pump based on timed
operation of the solenoid at a common operating point of 70
psi air pressure and 30 psi of back pressure.

PRESSURE SWITCH OPERATION

A calibration procedure is necessary for proper operation of
the pressure switch and accurate end of stroke feedback from
the pump. The Reset ring will always have a lower pressure
value than the Set ring.

1. Determine the operating air pressure of the pump.
2. The Reset ring should be set to approximately 25% of the
operating pressure of the pump with a minimum of 10 PSI.
3. The Set ring should be set to approximately 50% of the
operating pressure of the pump. This value is more vari-
able depending on the specific operating conditions. The
switch may function properly at much lower values for
the Set ring if the pump is running slowly, or at lower op-
erating pressures. In general, high operating speeds and
pressures require a higher setting value of the Set ring.
4. Operate the pump slowly to ensure proper operation of
the pressure switch. When the pump has shifted to one
side, the yellow LED will illuminate and remain on until
the pump shifts back to the opposite side.

Minimum distance between Set and Reset = 2% of the
final value of the measuring range.
To obtain the setting accuracy: Set both rings to the mini-
mum value, then set the requested value.
5. If the operating pressure of the pump changes, the
Set ring may need to be adjusted accordingly.

LEAK DETECTION (DIAPHRAGM fAILURE DETECTOR)
The diaphragm failure detector components must be
GENERAL DESCRIPTION
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.
An ARO® diaphragm pump equipped with the ARO
Diaphragm Failure Detector 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 cham-
bers which will send an output signal when fluid is detected.
ARO is not responsible for accidents resulting from im-
proper installation of components or hardware.
HAZARDOUS VOLTAGE. Do not attempt any service
without disconnecting all electrical supply sources.
INSTALLATION AND WARNINGS
NOTE: ALL WIRING MUST COMPLYWITH ALL LOCAL
AND / OR NATIONAL ELECTRICAL CODES.
Electrical codes that apply must be strictly adhered to;
failure to do so may lead to shock hazard or serious injury.
Some local electrical codes may require the installation of
rigid conduit.

cycle is known.
GENERAL DESCRIPTION
The ARO diaphragm pump cycle counter provides a closed
