CHAPTER 3: CONFIGURATION AND SETUP
087-0067 REV A SCOTT SAFETY
•
Drain - The HMI automatically determines when to perform a drain and the length
of time of the drain based on the factory defaults. Factory default for the drain
interval: 15Mins. The default for the length: 15Secs. A drain may be manually
performed when the user selects the Drain button.
•
Silence - Manually disables the horn(s) on the compressor.
•
Purge - A purge is automatically performed when the compressor restarts after an
alarm event for a monitored gas. The HMI monitors the gas levels and tracks the
run time. If either the gas levels drop to normal, or the two hour max run time is
reached, the HMI sends a command to the compressor to stop the purge. A purge
may be manually performed when the user selects the purge button.
•
Logout - Exists and returns to the pass code/scan card screen.
•
Alerts - Displays Override condition alerts and alert history. There are two types of
alerts: alerts with overrides and alerts without overrides. See
Figure 11 .
Figure 11 Alerts - Screen
– Alerts with Overrides - Overrides allow the system to continue operating while
parameters are out of tolerance up to a maximum default override limit or for
one hour, whichever occurs first. Each alert produces an associated audible
alarm via the horn. These reflect the factory default settings. See
Table 12 .
