• The volume per pump pulse, from 0.01 to 20.00 cc. Our pumps have cc/pulse ratings, but for greater accuracy
due difference in liquid properties, the user would need to calibrate the volume of each pump pulse at site,
using a measuring cylinder.
• Concentration of the chemical solution being pumped (% solution), eg. 5% Sodium Hydroxide, 98% Sulphuric
Acid, etc.
• PPM desired, from 0.1 to 20,000 p.p.m.
Using the information above, the microprocessor in the pump will calculate accurately the number of pump
pulses per volume of water which passes through the water meter.
8.1 DESCRIPTION OF ADDITIONAL FEATURES
FLOW ALARM WITH FLOW SENSOR (OPTIONAL)
Should the pump fail to pulse for any reason, an alarm buzzer sounds to warn the user. The pump then stops by
itself and a yellow warning LED comes on, signaling that it needs the user's attention. The relay output (con-
nector no. 1) is activated. The tolerance limit for the activation of this alarm to be activated can be set by the
user (the number of missed pulses before the alarm comes on).
Reference pulses: periodic break between a control and the following one.
Max count diff.: maximum pulses to which does not correspond liquid injection from the pump.
Example:
a) Reference value set by user = 100 pulses.
b) Maximum allowed variance = 12 pulses.
c) Actual pulses detected by the pump = X pulses.
If 100 - X > or = 12, then the pump will produce an audible alarm (buzzer). At the same time, the output relay
will also be energized.
RELAY SERVICE OUTPUT
Every time the pump is in alarm for lack of injection noticed by our flow sensor (not standard supplied), an inter-
nal relay switches on, whose exchange contact are available on the connector pos. 1.
REMOTE CONTROL
This function allows the user to activate or de-activate the pump from a maximum distance of 100 meters away,
using a contact switch. Two different polarities are available.
BUZZER
The pump is fitted with an acoustic alarm to warn the user (see paragraph 3.1, Flow Alarm). This sound alarm
can be manually disabled if so desired.
CLOCK
An on-screen clock is standard. This gives additional functions to the pump (eg. timer - see paragraph 3.5). The
clock shows the following information:
- Time in hh:mm (hours:minutes) format
- Day
- Date
- Month
- Year
TIMER
An in-built timer allows the user to program dosing cycles as follows:
• Timer Disabled: Pump works in manual mode without timer influence.
• Daily Timer: The user can program up to 8 start/stop cycles per day.
• WEEKLY TIMER: The user can program up to 8 start/stop cycles per week.
