able is full. Always correct the highest priority errors first.

Alarm
Relays
The
Octel Overture 200/300 provides both major and minor alarm relays, which can be used to light an
LED or sound an alarm. Refer to the Maintenance Commands chapter
, Alarm T
est section.
In the event of a power failure, both of these relays close the contacts to indicate the power failure. Both
relays remain closed during a subsequent restoration of power until the software boot process opens the
relays. However
, if there is an alarm condition prior to the power failure or an alarm condition arises
during the boot process, the relay(s) remain closed until the
CLEAR HARDWARE command
is given.
During operation, if any hardware error occurs, the minor alarm relay is closed. In turn, the major alarm
relay closes when an alarm call is attempted, subject to the priority of the hardware errors.
Hardware Error Types
The
following table outlines the probable cause and suggested remedy for errors. Clear errors with the
highest priority first. Priority 3 is the highest, 1 is the lowest.
