Remote Bench and Solenoid Valves: The 6020 is a single-chassis
instrument. However, the REMOTE BENCH and SOLENOID RETURN
connectors are provided on the interface PCB. The Remote Bench is wired
at the factory as well as any optional solenoid valves included in the system.
2.3 Testing the System
After The Control Unit and the Analysis Unit are both installed and
interconnected, and the system gas and electrical connections are complete,
the system is ready to test. Before plugging either of the units into their
respective power sources:
• Check the integrity and accuracy of the gas connections. Make
sure there are no leaks.
• Check the integrity and accuracy of all electrical connections.
Make sure there are no exposed conductors
• Check that sample pressure typically between 0 and 30 psig,
according to the requirements of your process.
Power up the system, and test it by performing the following operation:
1. Repeat the Self-Diagnostic Test.
2. Zero the instrument.
3. Span the instrument.
For steps 2 and 3, refer to part II for gas calibration.
