3.6 Cable extension
The transducer is connected using ALPHA XTRA-GUARD4 P/N45272. The standard cable length is 10 metres.
This cable comprises of two twisted pairs with an overall screen and drain. The brown and red wires from the
transducer should be connected to one twisted pair. The black and white wire from the transducer should be
connected to the other twisted pair. The yellow from the transducer should be connected to the drain wire which
must be terminated at the screen (SCN) terminal on the PCB.
Fitting instructions for extending the MSL603 transducer cable are in section 14.
Note 1:
The standard 10 metres of cable should be sufficient for most installations. The maximum recommended
additional extension is 20m. Use only cable conforming to the specification given above and ensure any
connections are made using high grade screened connectors. For suitable specification connectors refer to
Mobrey Measurement customer support. It is the responsibility of the installer to ensure that any extension to the
cable must be suitable for its working environment.
Note 2:
The digital input, if used must be connected to switch relay contacts which are insulated to IEC6010 category III
(4kV impulse) with no exposed live parts.
