Alarm
Reflash
To set the reflash operation on the alarm output relay, select [ON]. The reflash function
is set on the first three output relays.
Rate of Change Decrease
Set the interval for the rate-of-change calculation of the low limit on rate-of-change alarm
in terms of the number of sampled data points (1 to 32). The actual interval is obtained
by multiplying the value specified here by the scan interval.
Rate of Change Increase
Set the interval for the rate-of-change calculation of the high limit on rate-of-change
alarm in the same manner as the interval for the low limit on rate-of-change alarm.
Hold
Select the alarm indication behavior from the following:
Settings
Description
Unhold
Clears the alarm indication when the alarm condition is released (returns to
normal condition).
Hold
Holds the alarm indication until an alarm acknowledge operation is performed.
Internal Switch AND
Select the internal switches that are to operate using AND logic. Set the range of internal
switches (from the first internal switch) to take the AND logic. All subsequent switches
will be set to OR logic.
Relay AND
Select the relays that are to operate using AND logic. Set the range of relays (from the
first alarm relay) to take the AND logic. All subsequent relays will be set to OR logic.
Available settings are [None], [I01] (I01 only), [I01-I02] (I01 and I02), [I01-I03] (I01 to I03),
etc. Only alarm output relays that are installed are valid.
Note
When reflash is turned ON, the operation of the first three output relays is fixed to OR logic.
Specifying AND produces no effect.
Relay action
Select whether the alarm output relay is energized or de-energized when an alarm
occurs. The setting applies to all alarm output relays.
