17.17 Analog output

Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
Function

Analog output

* See section 9.5.1 Connection terminals, advanced functional
module, FM 300.
The analog output enables the transfer of certain operating data
to external control systems.
To set up the analog output, make the settings below.
Output signal
• 0-10 V
• 0-20 mA
• 4-20 mA.

Factory setting
See section 35. Factory settings.

17.18 "Controller"("Controller settings")

Pump variant
TPE3,TPE3 D
TPE2,TPE2 D
The pumps have a factory default setting of gain, K
time, T .
i
However, if the factory setting is not the optimum setting, you can
change the gain and the integral time:
• Set the gain within the range from 0.1 to 20.
• Set the integral time within the range from 0.1 to 3600 s.
If you select 3600 seconds, the controller functions as a
P controller.
Furthermore, you can set the controller to inverse control.
This means that if the setpoint is increased, the speed is reduced.
In the case of inverse control, set the gain within the range from
-0.1 to -20.
