7.8 Digital inputs/outputs
Available inputs/outputs depending on the functional module
fitted in the pump:
* See section
13. Identification of functional module
.
You can select if the interface must be used as input or output.
The output is an open collector and you can connect it to e.g. an
external relay or controller such as a PLC etc.
Fig. 25 Principle example of configurable digital inputs/outputs
To set up a digital input/output, make the settings below.
Mode
You can set the digital input/output 3 and 4 to act as digital input
or digital output:
• Digital input
• Digital output.
Function
You can set the digital input/output 3 and 4 to these functions:
Possible functions, digital input/output 3
Possible functions, digital input/output 4
Factory setting
See section
16. Factory settings
.
7.9 Signal relays 1 and 2 (Relay outputs)
The pump incorporates two signal relays for potential-free
signalling. See section
11. Signal relays
for further information.
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 the pump is stopped due to low flow. See section
Low-flow detection
on page 25 .
• Running (Pump running)
The pump is 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
7.15 Limit-exceeded function
.
• Limit 2 exceeded
When the "Limit 2 exceeded" function is activated, the signal
relay is activated. See section
7.15 Limit-exceeded function
.
• 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.
• Not active.
