Operation in zones of severe electrical interference
The measuring device complies with the general safety requirements in accordance with EN 61010 and
the EMC requirements of IEC/EN 61326 and NAMUR recommendation NE 21.
Caution!
Grounding is by means of the ground terminals provided for the purpose inside the connection housing.
Ensure that the stripped and twisted lengths of cable shield to the ground terminal are as short as possible.
• AC: < 15 VA (incl. sensor)
• DC: < 15 W (incl. sensor)
Switch-on current:
• Max. 3 A (< 5 ms) for 260 V AC
• Max. 13.5 A (< 50 ms) for 24 V DC
Lasting min. ½ cycle frequency: EEPROM saves measuring system data
• EEPROM or T-DAT (Promag 53 only) retain the measuring system data in the event of a power supply failure
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter, serial number,
calibration factor, zero point etc.)
