4.3.6 EVENT CONFIGURATION (Cont.)
EVENT SOURCES (Cont.)
Power up
A transient event is triggered at power up.
Maths channel partial failure
For recoders fitted with the Maths pack option, this event is set if, say, one of the inputs
to a group averaging function becomes invalid. In such a case, the average will be calcu-
lated on the remaining input values, but the result may not be as accurate as expected.
Loss of one input can also be important in functions such as Fvalue, where several sen-
sors may be distributed within the load and their outputs used in a group minimum calcu-
lation for input into the Fvalue equation.
Battery Low
This event is set when the battery is reaching the end of its useful life. The event re-
mains active until the battery is replaced.
Archive media % full
Triggered when the floppy disk or PC card has reached the % fullness defined in Archive
configuration (
section 4.3.5
).
Invalid Password Entry
Transient event at the point of an invalid password entry attempt
User Logged In
This event becomes active whenever a user with the specified Event Permission logs in.
The event remains active until all local and remote users, with the specified permission,
have logged out. See also
section 4.4.1
(Access levels).
Email Failure
This event source appears only if the e-mail option is fitted (options manual section 11),
and is triggered if an attempt to send an e-mail is unsuccessful.
SOURCE 1 SENSE
Allows source 1 to be used in its normal sense (Select 'Source 1') or inverted (Select 'Not Source 1').
Example: Source 1 is alarm 1 on channel 3
With Source 1 Sense = Source 1, the event is active whenever channel 3 alarm 1 is active.
With Source 1 Sense = Not Source 1, the event is active whenever the alarm is not active.
OPERATOR
This allows a logical combination of input sources to be used to trigger an event. The selections and their definitions
are shown in table 4.3.6, below.
Table 4.3.6 Logical operators for event sources
SOURCE 2 SENSE
Allows source 2 to be used in its normal sense (Select 'Source 2') or inverted (Select 'Not Source 2').
Example: Source 2 is Group 1 Batch Running
With Source 2 Sense = Source 2, the event is active whilst the batch is running.
With Source 2 Sense = Not Source 2, the event is active whilst the batch is not running.
Operator
Event active when:
Event not active when:
Only
S1 Active
S1 not active
AND
S1 and S2 both active
S1 and/or S2 not active
OR
S1 and/or S2 active
S1 and S2 both not active
NAND
S1 and/or S2 not active
S1 and S2 both active
NOR
S1 and S2 both not active
S1 and/or S2 both active
XOR
S1 or S2 active
S1 and S2 both active or both not
active
S1 = Source 1; S2 = Source 2
