3.8. Error Codes of the CM
The redundant controllers A and B on the CM have both an LED display (status
µC) for indication of error codes, assisting fast repair of any malfunction of the
gas detection system by simplifying the search of errors within a limited range.
Always of the first error recognized by the system is indicated. Only
error code
20 can be overwritten by an error recognized later on.
Code Description of Error
3 Controller A (or B) has activated its fault release, the cause for it can however not be
determined.
4 DPRAM error; the status of Controller A (or B) cannot be read by the DPRAM.
10 The printer is offline.
11 No paper in the printer.
12 DATA LOGGER: Storing chip is filled to capacity.
20
(only CPU A)
Failure in LED Module addressing. Be sure that the number of connected LED
Modules is the same as the number of configured input modules (in groups of eight).
21 Error in automatic recognition of LED Modules: Recognized addresses are not
consecutive or incomplete.
40 No valid values in the parameter memory.
41 Checksum error in flash memory.
42 Incomplete upload. Not all parameters set have successfully been loaded or initialized.
43 Incomplete configuration. No channels have been configured.
44 Error in loading or deleting the flash memory.
45 The system has not been activated.
46 The system could recognize several successive power failures.
47 The Controller has received instruction for RESET from the RS232 interface.
48 Error in configuration of input modules: e.g. Loop Module has an even address
60 The running time of the program (loop time) has been exceeded repeatedly.
61 Error in communication with the Analog Input Module. The measured values cannot
be read within the preset short period of time.
62 Error in memorizing measured values. No module can memorize any measured values.
63 Communication error with one or several relay modules.
64 Configuration error: Please check configuration of relay modules.
65 Time exceeding for Ignore communication fault with relay modules (switch position 6)
70 Hardware malfunction: The READY line remains at high level after reset.
71 Hardware malfunction: The RESET line remains at high level after reset.
72 Hardware malfunction: The RESET line remains at low level after reset.
73 Hardware malfunction: The fault relay is active during resetting.
74 Hardware malfunction: The fault relay does not switch.
77 Hardware malfunction: Error in testing of external UART (output modules).
79 Hardware malfunction: Overrun of external UART (output modules).
80 Hardware malfunction: Error in testing of internal RAM.
81 Hardware malfunction: Error in testing of external watchdog.
82 Hardware malfunction: Error in testing of flash ROM.
83 Hardware malfunction: Error in testing of external RAM.
84 Hardware malfunction: Verification error after loading into the EEPROM.
85 Software error: Variable outside the valid range.
