15.11 Relay outputs
The pump incorporates two signal relays for potential-free
signalling. See section 22. Signal relays for further information.
You can configure the signal relays to be activated by one of the
following incidents:
• Ready
• Operation
• Alarm
• Warning
• Limit 2 exceeded*
• Limit 1 exceeded*
• Pump running
• Relubricate
• Control of external fan
• Not active.
* Only TPE2 (D).
15.12 Analog output
Whether the analog output is available or not, depends on the
functional module fitted in the pump:
To set up the analog output, make the settings below.
Output signal
• 0-10 V
• 0-20 mA
• 4-20 mA.
Function of analog output
• Actual speed
• Actual value
• Resulting setpoint
• Motor load
• Motor current
• Limit 1 exceeded*
• Limit 2 exceeded*
• Flow rate
* Only TPE2 (D).
15.13 Controller settings
The pumps have a factory default setting of gain (K
p
) and integral
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 (K
p
) within the range from 0.1 to 20.
• Set the integral-action time (T
i
) within the range from 0.1 to
3600 s.
If you have selected 3600 s, the controller will function as a
P controller.
Furthermore, you can set the controller to inverse control.
This means that if the setpoint is increased, the speed will be
reduced. In the case of inverse control, set the gain (K
p
) within
the range from -0.1 to -20.
Guidelines for setting of PI controller
