                   VCD (VIGILANCE CONTROL DEVICE)

Vigilance control device (VCD) is one of the most safety item for locomotive. You have to operate locomotive continuously by notch UP-DOWN or press vcd push button switch,pressing sanding foot switch while running, otherwise after 60 second VCD SYSTEM gives you a warnig by glowing vcd CAB UNIT warning light for 8 second if you don't acknowledge this by pressing vcd push button switch then after completing 8 second,vcd warning light glows with a buzzer sounding for 8 second, if you don't acknowledge this time too then penalty brake activated and notch will be regress autometically,BP(BRAKE PRESSUR) will drop and auto flasher glows and locomotive will stop running autometically. You have to reset this vcd system for running locomotive again,but remember you won't be able reset for 32 second. After 32 second you will be able to reset this. After reset BP will charged. If system faulty while running and gives you abnormal working you can BY-PASS the system by putting HVCD switch to position '0'.
VCD MAIN UNIT AND CAB UNIT TOGETHER(VERSION-03)
TESTING PROCEDURE :-
  1. Release SA9=vigliance cycle start.
  2. Applied A9=vigilance suppressed.
  3. After vigilance cycle start press sanding footswitch,vcd cab unit push button, foot switch repectively to watch vcd acknowledge or not then do nothing vcd gives you all the warning and penlaty brake will applied then observe BP dropping,auto flasher glowing notch regress all the matters which mentioned above. If you get all this things properly then VCD works normal.

                          SMOOTHING REACTOR(SL) In WAP4 locomotives "SL" are used to get fine DC voltage from SILICON RECTIFIRE(RSI). SL-30 type smmothing reactor rating-- 1250 V and 1350 A . In locomotives 2nos. of SL used for two nos. of BOGIES. Each SL has a motor(MVSL). Any how if high voltage comes and passes through SL circuit for that safety perpous 2nos. of relay provided namely QVSL. For control HVSL 1 and HVSL 2 switches are provided in switch board. Term 'H' indicates PROGRAM SWITCH . This HVSL switch has 4nos. of position, i.e '0','1','2','3' . Position no. '0' indiactes motor(MVSL) Is deactive, Position no. '1' indicates relay & motor both are working, Position no. '2' indicates only relay working, Position no. '3' indicates relay bipas . CIRCUIT DIAGRAM :-
