Medha Servo Drives Pvt Ltd.
MAS 696 Operator’s Manual
system called "Auto Emergency Brake System", which by default initiates
Braking in the event of Train/Loco crossing the permissible set speed. The
microprocessor based inbuilt AEB system, developed by M/S Medha Servo
Drives Pvt. Ltd., is implemented on WDG4 and WDP4 Locomotives.
1.2.4 Blended Brake System
The MAS 696 system Locomotives are equipped with blended brake system.
It is simultaneously applying Dynamic Brake and Air Brake, when the driver
operates the Automatic Air brake handle in the service zone. The KNORR
CCB Air Brake system controls the Airbrake on the Locomotives and cars
coupled in train, and requests some amount of Dynamic Braking from LCC
for blended brake operation.
1.2.5 Manual TE Limiting
To avoid putting stresses on weak bridges when Locomotive is traversing
them, the Manual TE Limiting option was developed to enable the operator
to limit the Tractive Effort through (lighted) switch mounted on Engine control
panel. The position of the switch indicates the loco pilot that the feature has
been turned ON, indicating that the switch is active. The tractive effort limit
may be imposed by train line Input from another locomotive equipped with
this feature via TEL relay.
1.2.6 Auto Flasher
To switch ON of Flasher Lights automatically during Train parting, RDSO has
suggested modification in the existing Brake and Electrical control circuit of
Locomotives, to link switching ON of Flasher Light switch drop in Brake pipe
pressure on Locomotive. The flasher lights are applied automatically
whenever Emergency/penalty brake application takes place, as indicated by
the 'Loss of PCS'. The flasher can still be turned ON manually so that if the
operator have an Emergency that did not drop PCS, the Flashers can still be
activated.
