3.7.8 Security > Low Level Delay
With this function it is possible to delay the stop of the pump (and of the dosage) following the activation of the
tank level sensor.
When this function is active, and the level of the chemical reaches the minimum, the level alarm is activated
on the pump (on display, in the lower right corner, the text * LVL * will appear) but the pump continues to dose
for the time set, after which it stops.
When using a suction lance that maintains a safety margin, activating the level (without stopping the dosage)
allows you to have time to set up a new tank, without stop the pump dosing. This ensures better continuity of
dosage.
ATTENTION: this function must be activated only if you are using the suction lance with safety margin
like the LAFL of AQUA SPA (see
photo below).
It is possible to set a
delay in minutes
according to the
size of the tank in
use and the
quantity dosed by
the pump.

reached in this period.
To restore operation, an intervention on the pump is required.
