Definitions
Correct dosing stroke: A pulse from the dosing monitor
corresponds to the internal stroke signal within
acceptable time.
Incorrect dosing stroke: There is no pulse from the
dosing monitor corresponding to the internal stroke
signal within the acceptable time (the pump is not
pumping).
Logic
If a number of incorrect dosing strokes are performed,
the pump will continue operating, but it will change
over to alarm mode. The red indicator light will be on
and the alarm output will be activated (variant AR).
When a correct dosing stroke is detected, the red
indicator light is turned off and the alarm output is
deactivated.
Control panel lock
It is possible to lock the buttons on the control panel to
prevent maloperation of the pump. The locking
function can be set to ON or OFF. The default setting is
OFF.
A PIN code is required to change from OFF to ON.
When ON is selected for the first time, the indication
"_ _ _ _" appears in the display. If a code has already
been entered, the code will appear when an attempt to
change to ON is made. This code can either be re-
entered or changed.
Units
It is possible to select metric units (litre/millilitre) and
US units (gallons/millilitre).
Metric measuring units
• In manual and analog modes, set the quantity to be
dosed in litres per hour (l/h) or millilitres per hour
(ml/h).
• In pulse mode, set the quantity to be dosed in
ml/pulse. The actual capacity is indicated in litres
per hour (l/h) or millilitres per hour (ml/h).
• For calibration, set the quantity to be dosed in ml
per 100 strokes.
• In timer and batch modes, set the quantity to be
dosed in litres (l) or millilitres (ml).
Under the QUANTITY menu item in the COUNTERS
menu, the dosed quantity is indicated in litres.
US measuring units
• In manual and analog modes, set the quantity to be
dosed in gallons per hour (gph).
• In pulse mode, set the quantity to be dosed in ml/
pulse. The actual capacity is shown in gallons per
hour (gph).
• For calibration, set the quantity to be dosed in ml
per 100 strokes.
• In timer and batch modes, set the quantity to be
dosed in gallons.
Under the QUANTITY menu item in the COUNTERS
menu, the dosed quantity is indicated in gallons (gal).
