7.6.3 Advanced functional module, FM 300
The module has a number of inputs and outputs
enabling the motor to be used in advanced
applications where many inputs and outputs are
required.
The module has these connections:
• three analog inputs
• one analog output
• two dedicated digital inputs
• two configurable digital inputs or open-collector
outputs
• Grundfos Digital Sensor input and output
• two Pt100/1000 inputs
• LiqTec sensor inputs
• two signal relay outputs
• GENIbus connection.
See fig. 12.
• Inputs and outputs
All inputs and outputs are internally separated from
the mains-conducting parts by reinforced insulation
and galvanically separated from other circuits. All
control terminals are supplied by protective extra-low
voltage (PELV), thus ensuring protection against
electric shock.
• Signal relay outputs
– Signal relay 1:
LIVE:
You can connect supply voltages up to 250
VAC to the output.
PELV:
The output is galvanically separated from
other circuits. Therefore, you can connect the
supply voltage or protective extra-low voltage
to the output as desired.
– Signal relay 2:
PELV:
The output is galvanically separated from
other circuits. Therefore, you can connect the
supply voltage or protective extra-low voltage
to the output as desired.
• Mains supply (terminals N, PE, L or L1, L2, L3,
PE).
* If you use an external supply source, there must
be a connection to GND.
Fig. 12 Connection terminals, FM 300
Digital input 1 is factory-set to be start/stop
input where open circuit results in stop. A
jumper has been factory-fitted between
terminals 2 and 6. Remove the jumper if
digital input 1 is to be used as external
start/stop or any other external function.
DANGER
Electric shock
- Death or serious personal injury
- Make sure that the wires to be
connected to the connection groups
below are separated from each other by
reinforced insulation in their entire
lengths.
