3.10.1. Air Filtering – The air system shall filter incoming compressed air into the quality of air best suited for the RGMS. When the filter system does NOT adequately purify the quality of air to be consumed by RGMS, RGMS shall automatically shutdown and give a continuous visual indication of reason for shutdown. In no case shall failure to maintain/clean the filter system cause harm to the RGMS.

3.10.2. Air Pressure Control – To prevent damage and/or loss of accuracy, the RGMS shall be equipped with automatic “shut down” and pressure-relief system.

When supplied air pressure is lower than RGMS’s operating range, RGMS shall automatically shut down. When supplied air system is higher than RGMS’s operating range, pressure relief system shall be automatically activated to discharge excessive air; however, this operation shall NOT allow pressure to drop low enough to activate the “low-pressure” shut-off system. In the event that the pressure relief system should fail and air pressure approaches an intolerable limit without relief, the RGMS shall automatically shut down.

Whenever RGMS automatically shuts down, continuous visual indication of reason for “shut-down” shall be prompted. Under no circumstances, either low pressure or high-pressure supplied air shall cause harm to the RGMS.
