Connection Terminals - Grundfos TPE2 D Manual Del Usuario

9.5 Connection terminals

The descriptions and terminal overviews in this section apply to
both single-phase and three-phase motors.
For maximum tightening, see section
9.5.1 Connection terminals, advanced functional module, FM
300
The advanced module has three 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 sensors 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 electronic
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.
Therefor, 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.
Therefor, you can connect the supply voltage or protective
extra-low voltage to the output as desired.
• Power supply, terminals N, PE, L or L1, L2, L3, PE.
