In this mode the dip switch 4 set to ON inverts the on-off cycle, which basically means that the pump will start on
OFF instead of ON, after which the cycle will repeat itself whilst the pump is powered and the effect is an activation
delay compared to its being switched on.
Power Supply
Activation
(dip-switch 4 On)
Press the SEL button repeatedly until the corresponding LED comes on.
In this mode the T-on and T-off timers, the inversion dip switch 4 and the REM do not have any effect on the
operations.
When the pump is powered it carries out the strikes with the set frequency.

Dip-switch
Dip-switch 1) Time-Off scale mode: In the ON position, the full scale of the Off Time adjustment (T-Off) is equal to
60 minutes; in the OFF position it is equal to 180 seconds.
Dip-switch 2) enables/disables pump lock for alarm: in the ON position, the fixed red LED comes on but the pump
continues to dose in the event of a level or flow rate alarm; in the OFF position (default), the fixed red LED comes
on and the pump stops in the event of a level or flow rate alarm.
Dip-switch 3) alarm relay mode: in the ON position, the alarm relay is normally closed and opens when the alarm
signal is triggered; in the OFF position (default), the alarm relay is normally open and closes when the alarm signal
is triggered.
Dip-switch 4) enables/disables Time Off upon start up:
- Time On mode -
In the OFF position (default), the Time Off potentiometer is disabled. When switched on, the pump doses for the
set time and at the set speed. In the ON position, a pause is enabled upon start-up, meaning that before dosing,
the pump waits for the period of time set by the Time Off potentiometer (red regulation scale).
- Time On-Time Off mode -
In the OFF position (default), the pump doses in time-pause cycles (Time On – Time Off) in keeping with the set
times and speed. In the ON position, the pump inverts the times and doses in pause-time cycles (Time Off-Time
On), in keeping with the set times and speed.
Dip-switch 5) enables/disables the flow sensor: in the ON position, the pump is enabled to receive flow rate sensor
signals. After 6 strikes of the pump without receiving signals from the sensor, the pump goes into alarm mode. In
the OFF position (default), the connection to the flow rate sensor is deactivated.
NOTE: For greater accuracy in setting the Off Time, with the full scale of 60 minutes (Dip-switch 1 ON). Calculating
that between the two scales there is a multiplication factor of 20, the steps to follow are:
Transform the time to be set into seconds and divide it by 20
•
Set the Dip-switch 1 to OFF (full scale at 180 seconds)
•
Adjust the potentiometer to the calculated value and check it is correct with a chronometer.
•
Once the calculated value has been found set the full scale to 60 minutes (Dip-switch 1 ON)
