TC12 Installation, Commissioning & Maintenance Handbook 

Set the MODE and TRANSMISSION CONFIRM (TC) switches to the OFF 
positions. Connect the mains supply. Procedure is now according to the operating 
mode required. 
 

Note.  Using the OTS in OTU mode will affect transmission since the OTU 

input/output cable is detached from the OTU. This forces all OTU inputs to 
the "1" state and this will be transmitted to the Instation. 

 
Connect the two D-type plugs on the test cable 667/1/22658/000 or /001 
(depending on whether inputs 1 to 16 or 17 to 32 of the OTU wish to be monitored) 
to the D-type sockets on test cables 667/1/22658/002 and 003. Connect the test 
cables 667/1/22658/002 and 003 to the D-type plugs on the test unit marked 
'connect to controller only'. The berg sockets on the test cable 667/1/22658/000 or 
001 are connected to the test cables 667/1/22658/004 and 005. The test cables 
are then connected to the berg sockets on the end of the Outstation Input/Output 
cable (667/1/22693/000) which will be wired into the traffic control equipment. 

 

Check LED operation by using the LAMP TEST switch. Set the word selection to 2 
WORDS. 

 

Set the MODE switch to the OTU position. (If the connection fault indicator is lit 
return the switch to OFF and check that correct plugs are fully inserted before 
proceeding). 

 

Set up the required patterns for data Words 0 and 1 output to the traffic control 
equipment (Switches down to send control bit) - this simulates the 16 outputs on 
the OTU PCB. 

 
Note.  With both cable 667/1/22658/000 or /001 attached all 16 outputs are 

controlled. 

 

Set the TRANSMISSION CONFIRM switch ON (DOWN position). The controller 
should respond to the data pattern set on the switches. The reply words from the 
controller are monitored on the data indicators - the indicators show what the 
status of 16 of the OTU inputs would be. 

 
Note:  Controllers manufactured to MCE106 are not fitted with a Transmission 

Confirm facility. 

 

Repeat 5 as required allowing sufficient time for the controller to sequence 
according to the stipulated plan (approximately seven seconds).
