Possible reason for error
• Wrong EPROM-Code
• Defective hardware or strongly disturbed environment
• Defective hardware or noise-saturated environment
• The clock frequency of the processor is wrong
• User-Stack or System-Stack overflowed
• Possible software error due to recursive invocations (e.g. profile)
Control of the power stage (first shutdown) is faulty
The monitoring of the power stage has detected an error behaviour and
activated the second cut-off path of the power stage. The power amplifier is
disabled and the emergency stop is activated.
• A ramp has not been driven, eg door does not slow down
• Power amplifier output has not been switched off, e.g. when the unit is at a
standstill, further voltage is output
Second shutdown incorrect
The second micro controller does not trigger the Watchdog of the first micro
controller
Logical program execution monitoring failed
• Program execution not working as expected
• environmental interference
• faulty software
ROM Error of I/O Processor
• ROM Error of I/O Processor
RAM Error of I/O Processor
• RAM Error of I/O Processor
Faulty parameter checksum
• New EPROM version with different parameters
• Controller not yet initialized
Checksum from calibration values etc.
• New EPROM version with different EEPROM structure
• Controller not yet initialized
Converter parameters not plausible
• New EPROM version
• Controller not yet initialized
Program version / manufacturer code
• New EPROM version
• Controller not yet initialized
Faulty door cycle counter with active emergency
opening
• The door cycle counter does not count or is faulty. Because of this no
emergency opening testing can be done.
• A wrong software was programmed to the controller
• The programmed software does not know the hardware version
• The controller hardware is broken
Incompatible TST LGB software version
TST LGB with software version V3.21 or earlier in combination with DES-A
connected and activated.
Programming error with Real time clock
• The clock is not programmed plausible
