Process
5.1 Instrument Commissioning and
Start-up
After all water, air, and electrical connections have been made, the
SSR-Ex can be powered on by turning on the power to the Air Sentinel
II. Once power is supplied to the Air Sentinel II, it will run through an
automatic three-minute purge cycle and then supply power to the
SSR-Ex. If at any time there is a loss of pressurization in the electrical
enclosure, the Air Sentinel II will remove power to the SSR-Ex.
The condition of the Air Sentinel II can be determined based on the
color of the LED lamps on its body as explained by this chart:
