6.9 Functional modules
The functional modules are different types of add-on
boards containing various types of input and output
terminals for the user to connect different types of
sensors, for example switches and relays.
The product can only contain one functional module
at the time.
The following functional modules are available:
• FM110
• FM310
• FM311
3)
3)
Without Bluetooth (BLE).
The selection of module depends on the application
and the required number of inputs and outputs.

6.9.1 Functional module, FM110
Inputs and outputs
The module has these connections:
• two analog inputs
• two digital inputs or one digital input and one
open-collector output
• Grundfos Digital Sensor input and output
• one signal relay output
• GENIbus/Modbus connection
• two Safe Torque Off (STO) inputs
• Bluetooth (BLE) connection.
Signal relay 1
LIVE: You can connect supply voltages up to 250
VAC to the output.
SELV: The output is galvanically separated from other
circuits. Therefore, you can connect the supply
voltage or safety extra-low voltage to the output as
desired.
WARNING
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.
The 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 with safety extra-low
voltage (SELV), ensuring protection against electric
shock.
Cables for the relays must be double insulated or
reinforced and rated at least 250V/2A.
The Ethernet cable must be rated at least Cat5e/Cat6
with screening.
The 250V contacts of the alarm relays of
these devices must not be connected
directly to the supply mains, but energized
by an isolated power supply or transformer
with galvanic isolation.
