– Intrinsically safe applications
Explanation Intrinsically safe options:
For option PD-XI:
It is possible to supply the sensor with different voltages. You can set the voltage
with the switches. Internal power is only applicable for low power sensors (Coil, Reed). The sensor
supply is set by the firmware: 1.2V DC or 3V DC. External power is only available when the main
external power supply is connected. The sensor supply voltage is fixed: 8.2V DC.
Set the sensor supply
1. Make the F133-P safe. If applicable, mind the battery power.
2. Open the F133-P and carefully remove the cable-connectors and the protective cover.
3. Find and set the switches and select the V
out
as required.
4. Close the protective cover and install the cable connectors.
5. Close the F133-P.
Risk of electrocution - High voltage!
Make sure, all the leads to the terminals are disconnected from the F133-P and NEVER
connect the mains power supply to the unit when the protection cover has been removed!
