Graco CycleFlo [8/18] Setup and programming
8 309003
Setup and Programming
An 8-position DIP switch (SW1) (see Fig. 1 for loca-
tion) is used to set the cycle rate and cycles multiplier.
It is also used to invoke the various test modes.
Before the CycleFlo can be put into operation, the
parameters in Fig. 3 must be programmed for each
particular application.

Cycles Per Minute (CPM) Rate
The pump cycle rate is adjustable to accommodate
different pump sizes, varying product viscosity, and
product delivery speed. The pump cycle rate is mea-
sured in cycles per minute (CPM), which is the number
of times the pump performs a pump cycle in one
minute. One pump cycle consists of a momentary
pressurization of each one of the two diaphragms.
The CPM Rate Table in Fig. 4 shows the settings for
the first four switches of SW1 and the resulting CPM
rate.

Presets
The CycleFlo has 32 programmable presets to easily
switch between amounts of fluid delivered by the pump
during a RUN cycle. Each preset is programmed with
the number of times the pump will be cycled. Use the
Y and B buttons on the front panel to step through
the presets. The PRESET display will indicate the
selected PRESET program number and the CYCLES
display will show the associated number of pump
cycles.
NOTE: SW1–5 is the x10 Cycle Multiplier. If SW1–5 is
in the ON position, the actual number of pump cycles
will be 10 times that of the CYCLES display.
To change the number of cycles associated with a
programmed preset, do the following:
1. Place the CycleFlo into Program Mode by moving
SW1–6 to ON. The PRESET display will blink to
indicate that the Program Mode is active.
2. Use the BY buttons to select the PRESET to be
changed.
3. Press and hold the RUN button, then use the B
and Y buttons to adjust the 100’s digit of the
CYCLES display.
4. Press and hold the RESET button, then use the B
and Y buttons to adjust the 10’s digit of the
CYCLES display.
5. Press and hold the PRIME button, then use the B
and Y buttons to adjust the 1’s digit of the
CYCLES display.
6. Once the correct number of cycles is displayed,
use the B and Y buttons to move to another
PRESET and then back to the current one to verify
that the new cycle count was stored correctly.
NOTE: Either the B or Y button must be pressed for
the new cycle count to be programmed into the Cycle-
Flo’s memory.
7. Repeat for the next PRESET, as needed.
8. When finished, switch SW1–6 to the OFF position
to place the CycleFlo into Normal Operating mode.
