Installation Process
Commissioning
an Antaris EX-Z1
Before bringing the analyzer on line for the first time, you must clear the
supply line of debris and condensation, verify that the pressure indicators
and alarms are operating correctly, and in some cases, fine-tune the leakage
compensation valve. You will need the following tools for these procedures:
•
MiniPurge enclosure key
•
flat-blade screwdriver
•
stop watch or other timing device
Clearing the purge supply line
To remove debris and condensation from the purge gas supply line:
1.
Disconnect the supply pipe from the inlet to the purge system.
2.
Blow clean, dried air or nitrogen through the supply line for at least
15 seconds per meter (3 feet) of supply pipe length.
This removes any debris or condensation.
3.
If there are questions about the supply line pressure, connect a
pressure gauge and confirm that the supply line pressure being
delivered to the enclosure inlet is between 4 barg and 8 barg, 60 psi
and 115 psi, or 400 kPA and 800 kPA.
4.
Turn off the purge gas and reconnect the supply line to the
MiniPurge inlet.
Confirming alarm
and indicator operation
Each Antaris EX-Z1 analyzer includes a purge system and pressure sensors
that control power to the instrument. To verify that the system is operating
properly:
1.
Turn on the purge gas supply regulator to normal operating
pressure.
