5.5 Connection terminals
The descriptions and terminal overviews in this section apply to
both single-phase and three-phase motors.
For maximum torques, see section
5.5.1 Connection terminals, advanced functional module, FM
300
The advanced module has these connections:
•
three analog inputs
The factory-fitted analogue differential-pressure DPI sensor
for TPE Series 2000 is connected to one of these inputs.
•
one analog output
•
two dedicated digital inputs
•
two configurable digital inputs or open-collector outputs
•
input and output for Grundfos Digital Sensor
Not applicable for NBE, NBSE, NKE, TPE, TPED pumps. The
factory-fitted digital differential-pressure DPS sensor for NBE,
NBSE, NKE, TPE, TPED Series 2000 is connected to this
input.
•
two Pt100/1000 inputs
•
two LiqTec sensor inputs
•
two signal relay outputs
•
GENIbus connection.
See fig. 8.
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.
