Diagnostic Messages
The alarm and warning lists contain the alarms and warnings momentarily present.
Warning
is the condition that occurs when a variable reaches a critical value and/or when a
maintenance action is required but all actuator functions are still available. The flashing of
the alarm/warning LED indicates a warning condition.
Alarm
is the condition that occurs when a variable is outside the acceptable range and
some actuator function is not available. If the alarm/warning LED is on there is an alarm
condition. When the fault condition disappears, the corresponding alarm or warning also
disappears from the list.
A reset routine
is provided to clear the types of alarms and warnings that are memorized
(over-torque, jammed valve, etc.).
