CONFIGURATION EXAMPLES INTRINSICALLY SAFE APPLICATIONS:
Configuration example no. 1
*Sensor supply voltage for pulse tachometer type P : Terminal 3: 1.2
- 3.2V DC.
Please note: type PX may be used in combination with the battery (type PC).
PX will power the unit; the battery will be disabled automatically till power is disconnected.
