Milltronics ILE-37 – INSTRUCTION MANUAL

7ML19985CW01

Non-Hazardous Unit with Remote-Located LVDT 
Conditioner Card

*Where separation between the Integrator and LVDT conditioner exceeds 150 m (500 ft):

Remove the jumpers SF500 terminal 11/12 and 13/14

Run additional conductors:

- from SF500 terminal 12 to conditioner terminal block marked "InteEXC"

- from SF500 terminal 13 to conditioner terminal block marked "Integrator –EXC"

For further connection information on specific LVDTs, consult Siemens Milltronics.

Note: 

Shields are common, but not grounded to chassis. Run cable shields through 

SHLD terminals and ground at Integrator only.
