In this way it is possible to determine the last switch-on point of a fan, pump, etc.
connected via a digital output.
In the case of analog inputs and pseudo analog points, the last time an alarm limit
occurred is stored.
LED Mode (XF823x, XFL823x, and XFx830x modules)
The XF823x Panel Bus Binary Input Module, the XFL823x Lonworks Bus Binary
Input Module, and the XF830x / XFU830x modules support the “LED Mode”
attribute, which can be set in the CARE datapoint editor. The following attribute
options are provided:
• “Alarm” LEDs will be red/green (red = alarm state, not XF830x /
XFU830x modules)
• “Status” LEDs will be yellow/off (yellow = active state)
NOTE: XF830x / XFU830x modules do not support the Alarm option. Hence, do
not assign this attribute to datapoints allocated to one of these modules.
NOTE: When the XFL823x L
ONWORKS Bus Binary Input Module is used with
non-Excel 800 controllers, the LED mode can only be set in the
L
ONWORKS NV settings in CARE, and not in the CARE datapoint editor.
Maintenance Alarm
Specifying a maintenance alarm In the case of those datapoints for which an hours run log has been activated, a
time entry can occur within the attribute "Maintenance Alarm" to indicate after how
many operational hours an alarm message should be generated. Entering “Zero”
results in no alarm message.
Example:
Maintenance should be carried out every 500 hours on the heating circuit pump
controlled via a digital output. To achieve this, a time interval duration of 500 hours
is entered in the attribute "Maintenance Alarm" for this datapoint. At the same time,
activation of the hours run log must also take place in the attribute “Hours Run log”
for this datapoint. An alarm message now occurs after 500 hours, to bring to the
operator’s attention the necessary pump maintenance.
Manual Value
When the attribute "Operating Mode" is set to "Manual", the operator can enter a
manual value or state, and the application program will work with this manual value
or state until the operating mode is set back to “Automatic”.
