9.4.2 Connection terminals, standard functional module
(FM 200)
The standard 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.
See fig. 22.
• Inputs and outputs
All inputs and outputs are internally separated from the power
supply-conducting parts by reinforced insulation and
galvanically separated from other circuits.
All control terminals are supplied by safety extra-low voltage
(SELV), thus ensuring protection against electric shock.
• Signal relay outputs
– Signal relay 1:
LIVE:
Power supply voltages up to 250 VAC can be connected to
this output.
SELV:
The output is galvanically separated from other circuits.
Therefore, the supply voltage or safety extra-low voltage
can be connected to the output as desired.
– Signal relay 2:
SELV:
The output is galvanically separated from other circuits.
Therefore, the supply voltage or safety extra-low voltage
can be connected to the output as desired.
• Power supply (terminals N, PE, L or L1, L2, L3, PE).
A galvanically safe separation must fulfil the requirements for
reinforced insulation including creepage distances and
clearances specified in EN 61800-5-1.
Digital input 1 is factory-set to be start/stop input
where open circuit will result 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.
As a precaution, the wires to be connected to the
connection groups below must be separated
from each other by reinforced insulation in their
entire lengths.
