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
).
Important - Alert/danger ON trigger will be delayed by the configured
alert/danger enter time.
