Active STOP and Passive STOP
•
Active STOP
–
When the MCU receives a STOP command from the OCU (resulting from pressing the
STOP switch), it opens the main relays and transits into Passive Mode, getting ready for a new OCU
connection request.
•
Passive STOP
–
While in a connected state, if no valid RF telegrams are received within the passive STOP
delay (programmable in the TransKey), the MCU opens the main relays and enters into Passive Mode, as for
Active STOP.
3.8
Error Behavior
In the case of any internal error detection from one processor, an indication is given to the other processor and
the MCU enters Error Mode:
•
The main relays are released
•
RF reception is disabled
•
The error code is displayed on the “SYSTEM” LED (red blinking).
The MCU has to be switched off and then on again in order to be restarted.
6.9
RF AutoScan Mode
The MCU can either be programmed to a fixed RF channel, or programmed to operate in scan mode, where the
MCU continuously scans a predefined RF channel group until it receives valid RF telegrams from its peer OCU.
This programming is done in the MCU TransKey.
