7.5.2 Connection terminals, CME pumps
The CME pump 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. 9.
• 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 to the output.
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,
PE).
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.
