6.8 Mode 5 - Pulse input (Batch) -
In this mode, when the total number
of accumulated pulses is equal to the programmed pulse input value (Hz) ,
the pump will run for the programmed on time.
Two values must be programmed:
1)
ON-T
= The amount of time the pump will run when accumulated pulses
is equal to the programmed pulse input value (Hz).
2)
Hz maximum
= The number of input pulses that will trigger the batch.

Set the pump for mode 5
. Press the MODE button until
MODE 5
is
shown on the LCD display.

6.9 Measuring the Pump’s Output - Volumetric Test.
This volumetric test will take into account individual installation factors
such as line pressure, fluid viscosity, suction lift, etc. This test is the most
accurate for measuring the injector’s output in an individual installation.
1. Be sure the Injection Fitting and Footvalve/Strainer is clean and working
properly.
2. Fill a large graduated cylinder with the solution to be injected.
3. With the pump installed under normal operating conditions, place the
suction tubing with the Footvalve/Strainer installed in the graduated
cylinder.
4. Run the pump until all air is removed from the suction line and the solution
enters the discharge tubing. If the pump does not easily prime, remove the
discharge tubing from injection fitting until the pump primes. Re-connect
the discharge tubing to the injection fitting.
5. Remove the suction tubing from the graduated cylinder and refill the
graduated cylinder if necessary. Note the amount of solution in the gradu-
ated cylinder.
6. Place suction tubing with the Footvalve/Strainer installed back into the
graduated cylinder.
7. Run the injector for a measured amount of time. A longer testing time will
produce more accurate results.
8. Remove the suction tubing from the graduated cylinder. Measure the
amount of chemical injected.
