The error condition still exists after 1 hour has passed. This
situation causes the audible alarm to continue sounding once
every hour for approximately 5 seconds.
To clear all the fault code displays, press and hold the alarm control
switch for at least 5 seconds.
The alarm control switch does not affect either the error

functions as an enclosure power switch. Press the alarm control
switch on each enclosure to restore dc power to the enclosure.
