5.4 CONFIGURATION EXAMPLES INTRINSICALLY SAFE APPLICATIONS
5.4.1 F030-P-OT-PC-(PX)-XI-(ZB) BATTERY POWERED - Ex ia IIC/IIIC
Fig. 37: F030-P-OT-PC-(PX)-XI-(ZB) - Ex ia IIC/IIIC - Intrinsically Safe application.
*
Sensor supply voltage for pulse 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 F030-P, the battery will be disabled automatically until the power is disconnected.
5.4.2 F030-P-OT-PX-XI-(ZB) - Ex ia IIC/IIIC
Fig. 38: F030-P-OT-PX-XI-(ZB) - Ex ia IIC/IIIC - Intrinsically Safe application.
*
Sensor supply voltage for pulse 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 F030-P, the battery will be disabled automatically until the power is disconnected.
*Sensor supply voltage for pulse flowmeter 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.
