12. SUPREMA Sensor Data Sheets
The individual sensor connections are illustrated below. In addition, passive sensors are
monitored by SUPREMA for open or short circuits and these failures are reported as shown.
For active sensors, the input current signal is monitored, so that each failure is detected and
reported by the SUPREMA system.
There are also lists containing details of the operating current, power requirement of the sensors,
the maximum allowable cable lengths (maximum allowable cable resistance) and the screening.
For further information on the sensors, please see the Operating and Maintenance Instructions
for the individual sensor types.
Attention! For passive sensors, a 3-wire operation is conform to the requirements
according EN 50054 to output resistance up to 1.7 Ohm per lead resp. up to 3.4
Ohm loop resistance. If the loop resistance exceed 3.4 Ohm the 5-wire Operation
mode is recommended generally.
Attention! Only at use of the MCI 20-module with part no. 10043997 and 10044020
meets the requirements according to EN 50054 for active sensors at 3-wire
operation.
