MODE 2 : Other regulation
Operating in MODE 2
and set value control with encoder
In this case, the displayed value is a percentage
of the sensor range measurement.
By turning the encoder the requirement value
can be changed.
• Validate the new value.
With a short impulse on the encoder the actual
value can be displayed; the requirement value
reappears after 30 seconds or after on other
impulse.
An impulse around 1s allows the ON/OFF function.
• Select OFF.
• Validate.
Operating in MODE 2 and external set value
control
The set value is controlled by the input signal
0-10V or 0-20mA.
In MODE 2 – other regulation, the displayed
value is a percentage of the sensor range measu-
rement.
With a short impulse on the encoder the actual
value can be displayed; the requirement value
reappears after 30 seconds or after on other
impulse.
An impulse around 1s allows the ON/OFF function).
• Selec OFF.
• Validate.
Nota : the remote control (ex : switch) allows a stop
of the pump (converter ON).
When stopping the pump, the sign "OFF" appears.
7.1.3 With external control in frequency :
MODE 3 (fig. 10)
The pump is controlled with an external system.
Parameters input in MODE 3
• Set the switch on position SERVICE.
• Select M3.
• Validate.
• Select the external signal type (0-10V) or
(0-20mA) (default 0-10V).
• Visualisation of Operating time meter
(number of pump operzting hourse).
• Validate.
• Set the switch back on position OPERATION.
Operating in MODE 3
In Mode 3 the displayed value is a percentage of
the maximum pump speed.
With a short impulse on the encoder the actual
pressure can be displayed ; The requirement
value reappears after 30 seconds or after an
other impulse.
An impulse around 1s allows the ON/OFF function.
• Select OFF.
• Validate.
Nota : The remote control (ex : switch) allows a stop
of the pump (converter ON). When stopping the
pump, the sign "OFF" appears.
If a voltage signal (0-10V) is used and is lower than
1V, the sign "OFF" automatically appears.
If a current signal (0-20mA) is used and is lower than
2mA, the sign "OFF" automatically appears.
