Locations & Brief description of Cab equipment

Modified cab

LP‟s desk (In both cabs):-

BL Box - Lever Box with key (having ON & OFF). Top row BL switches is interlocked with
BL key (ON).
BOX-LEVER SWITCH: - It is having two positions CLOSE and OPEN, and operated manually
by a lever.
No. BL switches: 7 on top row & 8 on bottom row
In top row: BLDJ,BLRDJ, BLSN,BLPV,BLCPA,BLCPD& BLVMT
In bottom row: BLRA, Spare, BLZLF, BLLM, BLPRR, BLPRF, BLPRD & BLLF
Note: 1. Spare BL switch is used as BPSW/Addl. BLRDJ.
2. BLRDJ is spring loaded switch.
3. BLSN normal position is closed and remaining switches are normally open.

Signaling or Pilot lamps (In each cab):-
LSRSI LSDJ
LSB LSCHBA
LSP LSGR
LSOV LSAFI
LSDBR LSAFL
LSOL LSSIT(SIV locos)
LS Group: Above LP‘s head, Cab roof sealing

MP:- MP is master controller. It is a Cam operated switch, where a number of cams are
mounted on the shaft. On the top end of the shaft, the wheel is fitted, which is called as MP. By
Course material for ALP to become LP (G)
rotating the MP, the shaft rotates and cam rotates, causing closing and opening of switch
contacts.
Thus the MP operates control circuits of Tap Changer (GR) both for Traction as well
as Braking operations. MP is having two operations. Clockwise is Traction side and anti
clockwise is Braking side.

On Traction Side On Braking Side

0 Stable position
P Stable position
- Un stable position
- Un stable position
N Stable position
N Stable position
+ Un stable position
+ Un stable position

1. In ‗O‘ position, Traction Power Circuit is set to motoring side, that means CTFs will be in
Traction side (Up direction) and Contactor ‗C-145‘ remains opened.
2. In ‗P‘ positions, Traction Power circuits is set for Braking by CTFs setting towards
Braking side (Down direction) and C-145 Contactor closes.
3. When MP is moved to ‗0‘ position on traction side, the line Contactors will open.
4. When MP is moved to N position, line contactors will close.
5. When MP is moved to ‗+‘ position on either side, one notch Progression takes place.
6. When MP is moved to ‗-‗position on either side, one notch Regression take place.
7. When GR on notches, if MP is moved to ‗O‘, Quick Regression takes place (continuous
Regression to ‗O‘) and line contactors are also open.
8. When GR on notches if MP is moved to ‗P‘, Quick regression takes place to ‗O‘
9. If MP is moved from ‗P‘ to ‗O‘, Traction Power Circuit will set towards Motoring side (Up
direction) and Contactor C-145 opens

MPJ :- Reverses operating key (In each cab):- It is having 3 positions. Forward – Neutral -
Reverse. To set reversers forward direction this should be operated to forward position in
working cab. To set reversers reverse direction this should be operated to reverse position in
working cab. From Cab-I if this switch is kept on ‗F‘ both J1&J2 handles move upwards. From
Cab-II if this switch is kept on ‗F‘ both J1&J2 handles move downwards.

MPS:- Shunting contactors operating handle (In each cab):- This is having 0,1,2,3 (In WAP4
locos having 4th position also) positions. To increase the speed of train, after giving maximum
voltage and after taking 20th notch, this can be operated with a time gap of 30 seconds for each
operation.
Air conditioned CAB
In some locos Air conditioners are provided in both cabs ofthe loco instead of fans and heaters.
After energizing the loco, close all window shutters and switch on BLRA. The control unit for
air conditioner is provided on Loco pilot desk. Power ‗ON‘ switch for air conditioner should
be switched on. The air conditionerwill work only in the working cab. Nonworking cab BLRA
switch should be kept in ‗OFF‘ position.

Stick type Master Controller (MP)
In this Loco MPJ, MPS and MP is of stick type. MP is sub divided into 3 parts as
Traction/Brake controller, Brake lock and notch controller.

Instructions to operate stick type MP.

A. To keep reverser in forward / reverse direction, keep MPJ joystick No.1 (Handle lever) in
forward or reverse direction.
B. Through MPJ handle, if reverser is not set in required direction, then keep bye-pass switch
(No.6) in forward or reverse position.
C.To take notch on traction side with MP, move joystick No.2 (handle lever) to ‗T‘ position.
For notch progression, move joy stick No.5 to ‗+‘ position and leave and for notch
regression, move joy stick No.5 to ‗
D. If MP lever (joystick No.2) not works on ‗T‘ position, keep bye pass switch No.7 on ‗TR‘
position and work.
E.If Notch Lever (Joy stick No.5) fails i.e.notches are neither progressing nor regressing with
Notch Lever (Joy stick No.5) , keep bye-pass switch No.8 on bye pass position and take
notches through push button switches BPP or BPR (EEC operation).
F. For quick regression, keep MP handle(Joy stick No.2 ) from ‗T‘ to ‗O‘ position.
‗0‘ position.
G. For dynamic braking with MP, ensure MP (joystick No.2) is on ‗0‘, lift Brake lock handle
lever (joy stick no.3) upwards, now MP handle lock opens move MP handle lever(Joy stick
No.2) from ‗0‘position to ‗P‘ position.
H. To take notches on braking position, use joy stick No.5.
I. After dynamic brake to return to traction, release brake lock handle lever(joy stick no.3),
move MP handle lever(Joy stick No.2) from ‗P‘ position to ‗0‘ position.
J. To take shunting notches use Joy stick No.4 for the positions 1, 2, 3, 4.

ZPT :- Key for operating pantograph (In each cab) :- It is having 0,1&2 position. Irrespective
of cab when this switch is kept on ‗1‘ position rear pantograph will raise and if kept on ‗2‘
position same cab side pantograph will raise. In ‗O‘ position both pantographs are lowered.
Push button switches (In each cab):-These are spring loaded switches and used to close a
circuit or to open a circuit. The following are available on LP‘s desk.

BPP - Push button switch for progression of notches in EEC operation
BPR - Push button switch for regression of notches in EEC operation
BPT - Push button switch for testing signaling lamps. When pressed LSRSI& LSP lamps
glows.
BPQWC/ZQWC -Weight compensation relay switch:- This should be pressed when starting
heavy loaded train from yard and when GR is on ‗O/1st‘ notch.
BPQD – In microprocessor locos, to nullify QD action and can be pressed upto 10th notch.
BPSW- PB switch for quick charging of BP pressure.
SW – To stop AFL & buzzer sound at the time of AFL ckt energisation.

Toggle switches (In each cab):-

ZLC: Switch for cab lights.
ZFL: Switch for flasher light.
HPV: This is provided in dual brake locos. When this is operated second PV comes in service
in addition to working PV.

Tractive Effort limiting switch: In some of WAG7 locos below SPMs this switch is
provided. The following Messages were stenciled there.
 Do not exceed TM current 970 Amps, in case of 18:64 gear rartio.
 Do not exceed TM current 890 Amps, in case of 16:65 gear rartio.
This is to limit the tractive effort to 60T in double headed WAG 7 locos on bridges
with the span of 25.6M, 31.9M, 47.3M, 67M & 76.8M on BGML standard spans.
Loco pilots should operate this switch while entering into the section where such type
of bridges provided.

The ESMON type SPM consists of data like, Train No., Driver ID, Loco No., the
Train/Driver Start Dates and Times, End Date and Time, Run Distance and Time, Coasting
Distance and Time , Dynamic Distance and Time, Over speeds, Maximum Speed, Total
Energy, Halt Energy, Run Energy and Specific Energy etc.
While taken over charge Loco pilot has to enter his identity, train name, load of train
by using keys available on SPM. Also note down KWH consumed. While handing over also
note down consumed KWH and record in Loco Log Book.

 For illumination level in SPM use ‗9‘ No. button for maximum illumination and ‗0‘
No. button for illumination ‗OFF‘
