Push the sensor blocks into the guide rail so that the washers and locking screws can be
refitted.
Place replacement Gel pads down the centre of the sensor block.
Follow the procedure in section 8.5 for re-installing the guide rail on the pipe.
8.7 Electrical connection of the U1000 V2
The U1000 V2 operates in the voltage range 12 – 24 V (AC/DC). The power supply must have a
minimum rating of 7 VA per instrument. To fully meet the requirements of EMC regulations,
a 12 V connection is recommended for domestic and light industrial applications.
For full immunity to electrical interference the screen of the power/pulse output cable and
modbus cable should be connected to Earth.
For safety, connecting the U1000 V2 to a power supply via a mains rated transformer is the
responsibility of the installer to conform to the regional voltage safety directives.
Connect the external power supply to the Brown and Blue wires of the six-core cable.
8.8 4-20 mA, Pulse option
Connect the external power supply to the Brown and Blue wires of the six-core cable.
Connect the White and Green wires to Pulse and the Red and Black wires to 4-20 mA
input.
8.8.1 Interface cable
The U1000 V2 6-wire interface cable
12 V / 24 V input (brown)
12 V / 24 V return conductor (blue)
The SPNO MOSFET relay in the electronics module
supplies an insulated switching signal for a
switchable current of up to 500 mA and a voltage of up
to 48 VAC. This relay also provides 2500 V insulation.
Galvanically speaking, it is a volt free output.
