5.4.2 Connection terminals, advanced functional module
(FM 300)
The advanced functional module is only available as an option.
The advanced 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
• two LiqTec sensor inputs*
• two signal relay outputs
• GENIbus connection.
* Not applicable for TPE, TPED, NKE, NKGE, NBE and NBGE
pumps.
See fig. 10.
• 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 safety extra-low voltage
(SELV), thus ensuring protection against electric shock.
• Signal relay outputs
– Signal relay 1:
LIVE:
Mains 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.
• Mains 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.
Note
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.
Note
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.
