System Malfunctions
The room control module provides information about the current status of the RBW322-FTL-315/
MD15-FTL-315 controller set and any occurring malfunctions. The messages are shown on the
display. Therefore, observe the section "Operating and Malfunction Messages" in the chapter
"System Malfunctions" of the RBW322-FTL-315 operating instructions.
Operating and Malfunctioning Messages
Error messages can not be displayed independently. The are wirelessly transmitted to a room device
or a reader.
NOTE
If the wireless small actuator is operating in “self-controlled mode” with an external operator panel
and the wireless path/wireless communication is interrupted, the status bit “emergency mode”
(=self-controlled mode) is set (can be evaluated for service diagnostics).
After the malfunction has been rectified (details can be found in the documentation of the wireless
partner), the wireless partner is automatically resynchronized.
Battery monitoring
The battery capacity is continuously monitored. If the battery capacity is too low, a wireless signal is
transmitted to the wireless partner and 2 acoustic signal tones are emitted in succession every
6 hours. If this message is activated, the remaining capacity of the batteries is < 10%.
NOTE
Replace the batteries within the next 30 days when the capacity of the batteries is < 10%.
As the battery capacity decreases, the interval between the audible signals becomes shorter and the
number of signal tones increases to 4 signal tones in succession every 3 hours, then 8 in succession
every 2 hours.
If the remaining battery capacity is insufficient to maintain motorized operation, the actuator moves
into the safety position of 50 %.
The wireless communication with the wireless partner still functions in this operating state.
Replacing batteries
NOTE
This product contains replaceable alkaline batteries. Please dispose of the old batteries according to
local regulations.
