Probe Installation - Ecolab MULTRONIC Manuel Technique

Temperature sensor input connection
The connection provided for the temperature sensor input is a 3-wire connection system.
If the input is to be changed to a 2-wire connection system, the red jumper near the
terminals on the measuring module must be moved.
Jumper between 1 and 2: 3-wire connection system
Jumper between 2 and 3: 2-wire connection system

Probe installation

The probe has a pre-assembled 10-m long cable. A special terminal box and special
cable must be used for larger distances (see chap.

Conductivity Measuring Module (contact measurement)
The 3-wire connection system is preferable.
When using 2-wire connection systems the temperature measured is too high if
long cables are employed.
Terminals 83 (Input) and 84 (GND) must be used if a separate 2-wire connection Pt
100 is connected. The jumper must be positioned as described above.
If a separate 3-wire connection Pt 100 is connected, the additional shield must be
placed on terminal 84 (GND). The jumper must be positioned as described above.
The place of installation must be chosen in such a way that sufficient mixing is
warranted in the area of the measuring cell. The distance between measuring cell
and device may amount to a maximum of 10 m.
