Configure the XM-124 Standard Dynamic Measurement Module Chapter 2
Enable Enable/disable the selected relay.
IMPORTANT: The Relay Current Status is set to ‘Not Activated’ when the
relay is disabled.
See
page 100 .
Controls whether the relay must be explicitly reset after the alarm
subsides.
Activation Delay Enter the length of time for which the Activation Logic must be true
before the relay is activated. This value reduces nuisance alarms caused
by external noise and/or transient vibration events.
IMPORTANT: True Peak and True Peak-to-Peak signal detection is more
sensitive to transients and noise. To avoid false relay trips, it is
recommended that the Activation Delay value is greater than the
Overall Time Constant value when Signal Detection is set to ‘True Peak’
or ‘True Peak-to-Peak.’
IMPORTANT: The definition of each alarm can also include a Detection
Delay time. If so, the alarm must persist for the specified Detection
Delay time before the Relay Activation Logic can consider the alarm
condition. Consequently, if delays are applied to both the alarm and the
relay, the actual delay time of the relay is the sum of the Alarm
Detection Relay and the Relay Activation Delay. Enter a value between 0…65.5 seconds. The
default is 1 second.
Sets the relay activation logic:
• A or B - Relay is activated when either Alarm A or Alarm B meets or
exceeds the selected Alarm Status condition.
• A and B - Relay is activated when both Alarm A and Alarm B meet or
exceed the selected Alarm Status condition.
• A Only - Relay is activated when Alarm A meets or exceeds the
selected Alarm Status condition.
Options:
• A only
• A or B
• A and B
Sets the alarm that the relay monitors. The alarm must be from the
same device as the relay. When the Activation Logic is set to ‘A and B’ or
‘A or B’ you can select an alarm in both Alarm A and Alarm B. The system
monitors both alarms. When the Activation Logic is set to ‘A Only,’ you
can select an alarm only in Alarm A.
Alarm No. 1…16
IMPORTANT: You can only select an alarm that is
enabled.
Sets the alarm conditions that cause the relay to activate. You can select
more than one:
• Normal - The current measurement is not within excess of any alarm
thresholds.
• Alert - The current measurement is in excess of the alert level
threshold but not in excess of the danger level threshold.
• Danger - The current measurement is in excess of the danger level
threshold.
• Disarm-The alarm is disabled or the device is in Program mode.
• Xdcr Fault - A transducer fault is detected on the associated
transducer.
• Module Fault - Hardware or firmware failure, or an error has been
detected and is preventing proper operation of the device.
• Tacho Fault - A required tachometer signal has not been detected.
There is no transducer fault either.
Options:
• Normal
• Danger
• Xdcr Fault
• Tacho Fault
• Alert
• Disarm
• Module Fault
•
• Check to enable.
• Clear to disable.
