*
To operate, push each of the toggle switches ON-OFF, START-STOP and TEST-RESET to the desired function.
* Switch the power ON to unit. Select required batch quantity using rotary number dial selector switches.
* RESET unit. The LED displays zero and all LED indicators and alarm turns off. The unit is ready for batching.
* START unit; voltage contact drive activates. CONTACT DRIVE LED illuminates indicating pump or solenoid are energized,
followed by FLOW LED illuminating, indicating pulsing and operation of flowmeter. The digits begin counting upward towards the
selected batch quantity.
* Upon digits reaching the selected batch quantity the alarm sounds (short beep) indicating completion of batch; CONTACT DRIVE
and FLOW LEDs turn off. LED display digits and selected batch quantity should correspond. If LED digits overshoot target, use
PREACT (inflight,freefall) overflow deduct dials (located at rear of controller unit) to scale back the difference.
* To interrupt unit before completion of batch, push STOP toggle; digit counting will stop, drive contact off. Push START toggle to
resume batch.
* TEST toggle is used to test digit counting, switch contacts, alarm conditions or generate output pulses for computer interfacing.
TEST does not activate pump or solenoid.
Warning: if CONTACT or FLOW LED indicators are on, but controller is not counting, discontinue use and call for service.
CALIBRATION
1) The Batch Controller is initially set up for the connected flowmeter using
the Controller’s Calibration rotary selector knobs (at rear of unit) marked
UNITS, TENS and HUNDREDS to match flowmeter’s output pulse value.
Note reverse sequence of dials: e.g. U=0, T=0, H=3, is a value of 300.
On-site calibration adjustment and test:
2) Must adjust what is shown on the Batch Controller display (red LEDs) to
match a known amount dispensed, using the Calibration knobs. So, set
Controller to 190L, and batch into a 200 litre (44 gallon) drum.
3) If the amount collected is
more
than is shown on the LED display, then
decrease
the set calibration value by the same % difference
e.g. if collected 200L when 190L on LEDs, this is 10L more or 5% over
(10/190x100%). So, decrease the calibration value by 5% i.e. if calibration set to
300, new value is 300-5% = 300-15 = 285 (Set Calibration U=5, T=8, H=2).
4) If the amount collected is
less
than is shown on the LED display, then
increase
the set calibration value by the same % difference.
e.g. if collected 180L when 190L on LEDs, this is 10L less or 5% under
(10/190x100%). So, increase the calibration value by 5% i.e. if calibration set to
300, new value is 300+5% = 300+15 = 315 (Set Calibration U=5, T=1, H=3).
Example pulse flowmeter calibration settings
Note: x17 pulse input multiplier is used to enhance
calibration resolution if flowmeter has <58 pulses/Litre.

PREACT:
Calibrating inflight overflow is via two rotary select knobs marked "TENS" and
“UNITS” of LITRES, located at the rear of controller. Simply set knobs to same overflow reading as
indicated by the LED display.
Example: You select 190 Litres, batch the quantity, 200 Litres is shown on display, and 200 Litres
is collected in drum. A valve may take extra time to close, so what is selected on dials usually
overshoots on display. So, set 10 Litres on PREACT to deduct the 10 Litres overshoot (PREACT
T=1, U=0 is a value of 10 Litres). Next batch, the selector Dials, LED reading and amount collected
in drum are all 190 Litres.
