XXX-C, 66611
X-XXX-C, 66612X-XXX-C and 66613X-XXX-C
(refer to page 4).
• 3/8” and 1/2” Pumps - Pilot plug and replacement “O” ring(s).
• 1” Pumps - Screws, plate, gaskets, & template for leg modification.
GENERAL DESCRIPTION
The diaphragm pump Cycle Controller Assembly provides logic control
for presetdispensing.Wheninstalledona diaphragm pump,itcanmoni-
tor the diaphragm pump pulse or cycle and allow the user to accurately
control the number of cycles the pump will produce. This will effectively
allow a preset and repeatable amount of material to be dispensed
through the pumping system.
Pumps used with this counter assembly must be retrofitted with special
parts. These special parts will allow the pump to output a pilot air signal
which is needed to trigger the counter.
The controller assembly, with 1/4” N.P.T.inlet / outlet,includes a pre-as-
sembled countdown counter, palm operated valve, bracket, tubing and
an air regulator with air pressure gauge.
NOTE: This kit is intended to be attached directly to the pump air inlet.
Mountingit adistance fromthe pumpcould result in anair pressuredrop
in the pilot signal to the counter and may affect the accuracy.

OPERATION
Todetermine thenumberof cyclesneeded togetthe desiredoutput, use
the following formula: Divide the amount of material desired by the dis-
placementper cycleto getthecounter settingthat is needed(refer tothe
pump manual).
NOTE: For best results, operate the pump at 30 - 90 p.s.i. (2.1 - 6.2
bar). Fluctuations in the air pressure can affect the displacement per
cycle.Once thedesired displacement is achieved,keep theairpressure
as constant as possible.
BASIC OPERATION
1. Connect air to pump.
2. Set cycle count: Hold the reset button down while entering a new
number of cycles on the counter.
3. Press the palm button to start the cycle.
4. The pump will automatically shut off and resetto the count originally
set.
