14.14 Analog output
Whether the analog output is available or not, depends on the
functional module fitted in the pump:
* See section 22. Identifying the functional module.
The analog output enables the transfer of certain operating data
to external control systems.
To set the analog output, make the settings below.
Output signal
• 0-10 V
• 0-20 mA
• 4-20 mA.
Function of analog output
• Actual speed
the reading is a percentage of nominal speed.
• Actual value
The reading is a percentage of the range between sensor
min
and
sensor
max
.
• Resulting setpoint
The reading is a percentage of the external setpoint range.
• Motor load
Reading is a percentage of the range between 0 and 200 % of the
maximum permissible load at the actual speed.
• Motor current
The reading is a percentage of the range between 0 % and 200 %
of the rated current (I
N
).
• Limit 1 exceeded and Limit 2 exceeded
This function is only available on TPE2, TPE2 D pumps.
Limit-exceeded function is typically used for monitoring of
secondary parameters in the system. If the limit is exceeded, an
output, warning or alarm is activated.
•Flow rate
The reading is a percentage of the range between 0 and 200 % of
the nominal flow (Q
nom
).
Factory setting
See section 31. Factory settings.
