5.9.1.4 Lamp LSGR (Green) Tap changer GR zero position indication The lamp LSGR indicates whether the tap changer GR is at position '0' or away from that position. The auxiliary contacts 89-90 of the tap changer GR energizes the relay QV62 only at position '0' of the tap changer, the lamp LSGR being switched on by way of the contacts of the relay QV62. Lamp LSGR ON OFF Tap Changer GR At position '0' Not position '0' 5.9.1.5 Lamp LSR (Yellow) Monitoring of Readiness of J & CTF for running/braking operation as ordered by Master controller. The lamp LSR is switched on by the relay QV64 which in turn is energized by the contacts of the relay Q50 in de-energized position. Lighting up of signal lamp LSR (Yellow) indicates that the locomotive power circuit is not ready for moving tap changer for traction or braking. For the lamp LSR to go off the following equipment must be set in their proper position corresponding to the position of MP and MPJ on the master controller. Jl-2, CTF1-2, C145 with DJ in closed position. 5.9.1.6 Lamp LSRSI (Yellow) for rectifier monitoring The lamp LSRSI lights us when signaling fuse operates in the main rectifier due to blowing of any of the bridge fuse as a result of failure of any of the main diodes. 5.9.1.7 Lamp LSOL (Orange) & Lamp LS-Group (Red) The signal lamps are useful only during multiple unit operation of locomotives for detecting defective loco in the event of fault occurring in any of the locos. The relays QV60, QV61, QV63 and QV64 energizing the signal lamps LSDJ, LSCHBA, LSR and LSRSI respectively also energize signal lamp LS-Group and the relay QVLSOL. Defective locomotive is detected as follows: Faults on Leading Locomotive Lamp LSOL Lamp LS group. Indication on - • Leading Locomotive OFF ON • Trailing Locomotive (s) ON OFF
Fault on Leading Locomotive Indication on - • Leading Locomotive and Sound Trailing Loco ON OFF • Faulty Trailing Locomotive OFF ON 5.9.1.8 Buzzer SON 1-2 The buzzer sounds when relay Q20 operates due to TM voltage going above 865 V DC. 5.10 LIGHTING CIRCUITS 5.10.1 Head Lights (Ref.fig.5.10.1) The Headlights PR1 and 2 are equipped with 32 V, 250 W lamps which are supplied from a headlight voltage stabilizer RTPR connected to 380 V single phase ac source from the Arno converter. Switch ZRT is provided for switching on RTPR. Fuse CCRTPR protects the RTPR. The headlights are switched on by means of head light switch BLPRF(front light) or BLPRR(rear light) only one headlight at a time can be switched on. The headlights can be dimmed by the switch BLPRD ON the BL box. This operation changes over supply to headlights from a 32 V ac to 16 V ac tapping on the RTPR. 5.10.2 Marker & Instrument Lamps (Ref.fig.5.10.2) The following lamps are switched ON by the switch BL1LF or BL2LF (Marker Lights) in the respective cabs: • Lamps for the BL switch box, LBL1-1, LBL1-2. • Lamps for the pneumatic instruments and notch indicator LP1, LP3, LP5 (LP 2, LP4, LP6 in Cab2) and for the marker lights while LF1G, LF1D (LF2G and LF2D in Cab2). By operating switch BL1ZLF (BL2ZLF) to ON position marker lights white LF1G, LF1D (LF2G, LF2D) change over to Red provided switch BL1LF (BL2LF) in ON. All the above lights in Cab1 and Cab2 are protected by fuse CCLF1, CCLF2 respectively. The following lamps are also switched ON by the switch BL1LF (BL2LF) in Cab1 & Cab2 from the stabilized voltage of 24 Volts ac from the voltage stabilizer RTPR. Dual illumination lamps for measuring instruments LU1, LUA1, LA1-1, LA1-2 (LU-2, LUA2, LA2-1, LA2-2) and for the speedometers. 5.10.3 Engine Room Lamps, Ceiling Lamps & Sockets The lamps LCl-1 and LCl-2 or LC2-1 and LC2-2 for the ceiling lamps (Spotlights) in the
