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
).
