Siemens TRAFFIC CONTROLS TC12 사용자 설명서

 

TC12 Installation, Commissioning & Maintenance Handbook 

 

 

The power is turned off and back on, or 

 

 

The OTU is re-initialised using the three reset commands. 

 

Bit 2:  The Integral OTU/LMU has appeared to have failed or is not 

connected and integral RLM is configured. This will switch the 
lamps off and not allow them back on even if the OTU/LMU has 
come back on line. 

 

Bit 3:  The controller has detected an inconsistency in the lamp fault 

indications generated by the OTU. The OTU should detect such 
faults before the controller and put a fault in its own log. 

 

Bit 4:  The shared RAM format used by the fitted OTU is not compatible 

with the firmware on the Controller. 

 

Bit 5:  The integral OTU facility is enabled and an integral OTU has been 

detected but one is not supposed to be fitted. 

 

Bit 6:  Configuration Fault: The integral OTU facility is enabled in the 

config PROM but the use of the second config area in the PROM 
(where the default OTU configuration resides) is not enabled. 

 

Bit 7:  Not Used

OTUCFLG - Integral OTUs current fault flags 
 
The Integral OTUs Current Fault Log Flags - see OTU documentation. 
Normal examination of the OTU's fault logs should be made using the OTU 
commands 'GLF' and 'GLD' rather than these engineering commands. 
 

Note:  This command can still be entered even if no Integral OTU is fitted or one 

is connected but has failed but will obviously not return the correct values.

OTUCDAT - Integral OTUs current fault data 
 
The Integral OTUs Current Fault Log Data - see OTU documentation. 
Normal examination of the OTU's fault logs should be made using the OTU 
commands 'GLF' and 'GLD' rather than these engineering commands. 
 

Note:  This command can still be entered even if no Integral OTU is fitted or one 

is connected but has failed but will obviously not return the correct values.
