Grundfos TPE2 Installation And Operating Instructions Manual page 14

8.5.1 Connection terminals, advanced functional
module, FM 300
The advanced module has these connections:
• Three analog inputs.
• One analog output.
• Two dedicated digital inputs.
• Two configurable digital inputs or open-collector
outputs.
• Input and output for Grundfos Digital Sensor.
The input and output are not applicable for TPE2,
TPE2 D pumps. The built-in sensor for TPE3,
TPE3 D pumps is connected to this input.
• Two Pt100/1000 inputs.
For some pumps, the built-in temperature sensor
is connected to Pt100/1000 input 1 (terminals 17
and 18).
• Two LiqTec sensor inputs.
• Two signal relay outputs.
• GENIbus connection.
See fig. 19.
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.
• 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.
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,
