Standard Functional Module, Fm 200 - Grundfos CMBE 1-44 Installation And Operating Instructions Manual

6.2 Standard functional module, FM 200

6.2.1 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
• two signal relay outputs
• GENIbus connection.
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 with protective extra-
low voltage (PELV), ensuring protection against
electric shock.
6.2.2 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.
6.2.3 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.

Death or serious personal injury
‐
Make sure that the wires to be connec-
ted to the connection groups below are
separated from each other by rein-
forced insulation in their entire lengths.
