BATCH SET UP
72100-00 BATCH CONTROLLER
1. Hit the Set button to enter Setup mode and then
adjust the values and move the cursor (using the
left and right arrow buttons) and raise or lower
the values (using the up and down arrow buttons)
until you have all the values where you want
them.
2. Hit the Set button again to get out of Setup mode.
3. The practice of using the 4-20 Signal to Stop
the Pump should Be set Using 4ma as "off" By
default and 5ma as the slowest Speed or 20ma
as "off" in the reverse setup. Putting a zero as a
speed can sometimes create math problems for
the processor.
4. The System is now ready to Run (or Jog).
5. The sensor supplying the loop current, the 72100-
00 unit, the pump, and even the fluid ("heads" And
viscosity) and the air supply to the pump all have
tolerances on their performance. The exact flows
will need to be dialed in.
6. To run the system, flip the switch to the right. The
display will tell you the loop current and the pump
speed.
7. To run the pump, to purge it, prime it, or simply
to pump a little product; flip the switch to the left.
The unit will display the pump speed which is the
average of the setup high and low speeds.
NOTE: DO NOT USE ZERO AS A SPEED & ALWAYS
OBSERVE SIGNAL POLARITY & CURRENT LIMITS

CALCULATING VOLUMETRIC DELIVERY
The pump manufacturer supplies information about
the delivery of fluid per pump stroke (emptying of one
chamber), but factors like inlet and outlet head, inlet
air pressure and flow delivery, viscosity and cavitation
all effect the volumetric flow. Dividing the desired
flow rate by the displacement per stroke will provide
the estimated desired pump speed. Since there are
many factors that can change the displacement per
stroke, the exact speed will need to be dialed in.
