Example of Alert Disabled but Danger Enabled.
•
Enter Time:
represents the period for a channel to have exceeded an
alarm level before an actual alarm condition is raised. Alert/Danger ON
trigger will be delayed by this Enter Time.
•
Trip Multiply Factor:
use this value to temporarily increase the already
set alarm levels when trip multiply is activated. The entered factor must be
between the values of 1 and 25, with a single decimal being allowed (i.e.
1.5)
•
Trigger Relay:
check this box if an alarm condition shall trigger a relay. A
channel can be set for trigger relay on more than one alarm settings such
as alarm levels, Gap alarm levels and combined measurement alarm
levels. If a channel is set for more than one trigger relay, the relay will
trigger when at least one alarm condition is met. It is using an "OR" logic.
•
Hysteresis:
Use this value to prevent rapid alarm state switching.
Hysteresis values are used to determine when to leave the alert/danger
state (See Hysteresis).
Important - Alert/danger ON trigger will be delayed by the configured
alert/danger enter time.
