Provisioning Analog Alarms
When the
A
button next to a measured parameter is pressed the Analog Alarm Setup screen shown below will appear.
There are 4
Alarm Limits
that can be set independently and an
Alarm Enable
check box for each alarm limit. When the
enable box is checked, the alarm will occur when the
Present Value
crosses the
Alarm Limit
. In the example below
there is a Minor Alarm because the
Present Value
is below the
Minor Low Alarm Limit
.
The
Deadband
setting provides
hysteresis so the alarm does not
chatter if the
Present Value
is right at
the alarm limit. For high alarms, the
alarm will occur when the
Present
Value
is greater than the
Alarm Limit
.
The alarm will clear when the
Present
Value
is less than the
High Alarm Limit
minus the
Deadband
. Likewise for a
Low alarms, the alarm will occur when
the present Value is less than the
Alarm Limit. The alarm will clear when
the
Present Value
is greater than the
Low Alarm Limit
plus the
Deadband
.
Minor and major alarms operate independently so as the
Present Value
moves a minor alarm will become a major
alarm and vice versa.
Values in Yellow indicate a minor alarm, red indicates a major alarm and normal values are black.
All alarm settings are nonvolatile and will be saved in the RBMS Plus database.
SNMP traps and/or e-mails may be sent whenever the alarm state changes and when the alarm returns to the normal
state. Refer to the Telnet Setup section of this manual for information on setting the trap destinations and e-mail
addresses.

Provisioning Discrete Alarms (with optional sensors)
Whenever the
A
button next to a discrete indicator is pressed the Discrete Alarm Setup display will be shown. A
description of the indicator and the present state will be displayed. The present state will be color coded with the
alarm status, red for major, yellow for minor, and black for no alarm. Use the radio buttons to select either the
Disable
,
Minor
or
Major
alarm.
All alarm settings are nonvolatile and will be saved in the RBMS Plus database.
SNMP Traps and/or e-mails may be sent whenever the alarm state changes and when the alarm returns to the normal
state. Refer to the Telnet Setup section of this manual for information on setting the Trap destinations and e-mail
addresses.
