13.12 "Signal relays 1 and 2" (Relay
outputs)
* See section 7.5.1 Connection terminals,
advanced functional module, FM 300.
The pump incorporates two signal relays for
potential-free signalling. For further information, see
section 18. Signal relays.
Function
You can configure the signal relays to be activated
by one of the following incidents:
•Not active.
• Ready
The pump can be running or is ready to run and
no alarms are present.
•Alarm
There is an active alarm and the pump is
stopped.
• "Operating" (Operation)
"Operating" equals "Running" but the pump is still
in operation when it has been stopped due to a
warning.
• "Running" (Pump running)
• Warning
There is an active warning.
• Limit 1 exceeded
When the Limit 1 exceeded function is activated,
the signal relay is activated. See section
13.17 Limit-exceeded function.
• Limit 2 exceeded
When the Limit 2 exceeded function is activated,
the signal relay is activated. See section
13.17 Limit-exceeded function.
• Relubricate
• "External fan control" (Control of external fan)
When you select "External fan control", the relay
is activated if the internal temperature of the
motor electronics reach a preset limit value.
Factory setting
See section 30. Factory settings.
13.13 Analog output
* See section 7.5.1 Connection terminals,
advanced functional module, FM 300.
The analog output enables the transfer of certain
operating data to external control systems.
To set 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
.
