Operating in MODE 2 pressure regulation and
external set value control
The set value is controlled by the input signal 0-
10V or 0-20mA.
For the starting up, we recommend to set the
motor speed at 60% of its maximum pressure.
With a short impulse on the encoder the actual
pressure can be displayed; the requirement pres-
sure reappears after 30 seconds or after on 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.
MODE 2 : Other regulation
Parameters input in MODE 2
• Set the switch (fig. 4 - item S) on position
SERVICE.
• Select "M2".
• Validate.
• Select the source of set value Internal/External,
Default "I"
(set value adjustment by encoder)
• Validate.
• If the external set value "E" is validated,
(set value adjustment by external signal)
select the signal type (0-10V) or (0-20mA).
• Validate.
• Select the regulation type "O" for other regula-
tion.
• Validate.
• Select the type of sensor (0-10V) or (4-20mA).
(the information which is blinking is the one vali-
dated).
• Validate.
• Display "P" parameter of PID.
• Validate.
• Select the "P" value (default P=1).
• Validate.
• Display "I" parameter of PID.
• Validate.
• Select the "I" value (default I=1s).
• Validate.
• Display "D" parameter of PID.
• Validate.
• Select the "D" value
(default D=0ms)
• Validate.
• Visualisation of the Operating time meter.
