L: Low limit. Any the process is lower than low limit, the alarm or job is actuated.
HH: High High limit, to set up another limit higher than high limit for double warning.
LL: Low Low limit, to set up another limit lower than low limit for double warning.
Dev+: Trigger an event on positive deviation of process value. The job or alarm is activated when
process value is deviated more than the set point in positive direction. (Set point +Previous
sampled Process Value)
Example:
Set point =10
At 10.00.01 Hrs Tag1=40
At 10.00.02 Hrs Tag1 = 51
Then, job or alarm is activated
Dev-: Trigger an event on negative deviation of process value. The job or alarm is activated when
process value is deviated less than the set point in negative direction. (Previous sampled Process
Value-Set point)
Example:
Set point =10
At 10.00.01 Hrs, Tag1=40
At 10.00.02 Hrs, Tag1 = 29
Then, job or alarm is activated.
Error: On Channel error, an alarm or job is activated
Set point: To set up the process value for actuating Job1 and /or Job2
Alarm
Log Alarm: Record alarms
Log Alarm (Auto Ack): Record alarms and acknowledge automatically
Log Event: Record events
Job1, Job2:
When an event occurs, the task to be performed is called the job. A typical example is to
trigger an alarm buzzer in the event of a high temperature. Each Channel can accept five different
types of events (or alarms) and each event can create two jobs. Please note that a job under Event
is different from a job created by pressing the Operate key. The former is actuated by an event,
and the latter is actuated by manual control, no event necessary.
Note: Please refer to the section “Jobs”in Recorder user manual for full details about
various jobs available
