Events
The microprocessor stores events in the Log Book using a short
notation. The Log Book can store up to 99 events. When the 100th
event occurs, the "oldest event" is dropped making room for the
new 100th event. The Log Book events are maintained until an in-
struction is received to erase all entries.
All Log Book entries start with a "H" (for History) followed by a two
digit running number and a short description of the event. If a relay
trips, the Log Book entry identifies the relay and the cause of the
relay trip.
Example :
Cause
Relay
Entry number
If the event is a logical AND combination of events, the combina-
tion is displayed. In this case, the plus sign replaces the AND.
A trip of the OK-Relay generates one of the fol-
lowing Log Book entries:
Event Cause
OK POWER OFF OK-Relay is active for 15 safter po-
wer is returned.
OK A OK-Relay is active.
