General Appendix F: Upgrading

The following procedure will assist you if you are upgrading from a MultiRanger Plus to a
MultiRanger 100 or MultiRanger 200.
If the application is unchanged, copy down the parameters in the MultiRanger Plus
before de-commissioning the unit.

Mounting a MultiRanger 100/200

Please read the MultiRanger
MultiRanger 100/200.
Make sure the power is OFF to the unit before following these steps:
1. Remove the old MultiRanger Plus.
2. Mount the new MultiRanger 100/200 using the same mounting holes.

Connecting the Transducer

Unlike the MultiRanger Plus, coaxial cable is not recommended for use with
Important:
the MultiRanger 100/200 for transducer cable extensions. The MultiRanger 100/200
circuit is designed to use shielded twisted pair cable. Ideally, the coaxial cable should be
replaced with twisted pair.
If this is not practical, please refer to the Coaxial Transducer Extension section below.

Coaxial Transducer Extention

The MultiRanger 100/200 uses a new differential input receiver that works either directly
connected to the transducer lead or with a screened twisted pair extension cable via a
field junction box. This arrangement, using two conductors and a screen, gives
considerably better electrical noise immunity than the previous coaxial arrangement (up
to 20dB) and will give reliable operation in applications where the proximity of power
cables, variable speed drives etc. would have caused problems.
If you are installing a new MultiRanger system we strongly recommend that you use a
good quality screened, twisted pair cable if an extension is required. If the integral
transducer cable is used you need only connect to the MultiRanger and benefit from the
superior performance.
