Analog Output - Grundfos Hydro Multi-E Series Installation And Operating Instructions Manual

13.6 "Analog output"

The analog output enables the reading 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"
Signal range
[V, mA]
0
"0-10 V" 0 V
"0-20 mA" 0 mA
"4-20 mA" 4 mA
The reading is a percentage of the rated speed.
• "Actual value"
Signal range
[V, mA]
Sensor
"0-10 V"
"0-20 mA"
"4-20 mA"
The reading is a percentage of the range between the minimum
and maximum value.
• "Resulting setpoint"
Signal range
[V, mA]
"0-10 V"
"0-20 mA"
"4-20 mA"
The reading is a percentage of the external setpoint range.
• "Motor load"
Signal range
[V, mA]
"0-10 V"
"0-20 mA"
"4-20 mA"
The reading is a percentage of the range between 0 and 200 % of
the maximum permissible load at the actual speed.
• "Motor current"
Signal range
[V, mA]
0
"0-10 V" 0 V
"0-20 mA" 0 mA
"4-20 mA" 4 mA
The reading is a percentage of the range between 0 and 200 % of
the rated current.

This function is typically used for monitoring secondary
parameters in the system. If the limit is exceeded, an output, a
warning, or an alarm is activated.
• "Flow rate"
Signal range
[V, mA]
"0-10 V" 0 V
"0-20 mA" 0 mA
"4-20 mA" 4 mA
The reading is a percentage of the range between 0 and 200 % of
the nominal flow.
