54 Configuration Parameters
Triggered Trend Parameters The XM-360 module can collect a triggered trend. A triggered trend is a
time-based trend that is collected when a relay is activated, or the module
receives a trigger event.
Once the triggered trend is configured, the XM-360 continuously monitors the
trended measurements. When a trigger occurs, the XM-360 collects additional
data as specified by the Post Trigger parameter.
The XM-360 can only store one triggered trend. Unless the triggered trend is
latched, the trend data is overwritten with new data when the next trigger
occurs.
The triggered trend parameters define the trend data that is collected by the
module. Use these parameters to select the measurements included in the
IMPORTANT
The 4-20mA outputs are either on or off. When they are
on, the 4-20mA outputs overshoot the 4 and 20mA limits
by 10% when the measurement exceeds the minimum and
maximum range. This means the minimum current
produced is 3.6mA and the maximum current produced is
22mA.
When the 4-20mA outputs are off, they produce a current
approximately 2.9mA. The 4-20mA outputs are off under
the following conditions:
• The 4-20mA outputs are set to "Disable" (see Enable
above).
• The module is in Program mode.
• A sensor out-of-range error occurs that affects the
corresponding measurement.
