How to Cut-out/Disable Traction motor of BEP32 model Locomotive (6600 series) using monitor

How to Cut Traction Motor of BEP-32 Model Locomotive (EMD System) Using Monitor

For BEP-32 (EMD System) locomotive, Traction Motor (TM) cut-out is done through the EM2000 / Onboard Display Monitor.

Important: Always perform TM cut-out only when required and according to railway operating rules. Keep locomotive safe before cut-out.

Step 1: Make Locomotive Safe

Throttle → IDLE
Dynamic Brake → OFF
Reverser → NEUTRAL
Independent Brake → Applied
If required, isolate locomotive

Step 2: Open EM2000 Monitor

Go to:

Main Menu → Traction Control → TM Cutout

Sometimes shown as:

Traction Motor Cutout
TMCO Screen
Motor Cutout Screen

Step 3: Identify Faulty Motor

Monitor will show:

Select the faulted traction motor according to alarm/fault indication.

Example: If fault is in motor no. 3 → Select TM3

Step 4: Change Status

Change:

CUT IN → CUT OUT

NORMAL → ISOLATED

Use:

Soft Key
Function Key
Arrow + Enter Key

Step 5: Cut Out Speed Sensor (If Required)

Sometimes in EMD locomotives, both the Traction Motor + Corresponding Speed Sensor must be cut out.

Example: TM4 fault → Speed Sensor 4 may also require isolation.

Step 6: Acknowledge Alarm

Reset fault if required
Confirm no immediate trip occurs
Loco will run with reduced horsepower

Step 7: Observe Restriction

Reduced pulling capacity
Speed restriction may apply
Report to control/shed

Viva Short Answer

Question: How do you cut out traction motor in BEP-32 EMD locomotive from monitor?

Answer: First I keep throttle idle, reverser neutral and locomotive unloaded. Then I open EM2000 monitor and go to Traction Control or TM Cutout screen. I select the faulty traction motor number from TM1 to TM6 and change its status from Cut In to Cut Out. If required, I also cut out the corresponding speed sensor. Then I acknowledge alarm and run the locomotive with reduced power while reporting to shed.

Extra Viva Question

Why is speed sensor also cut out?

Because wheel slip detection and axle protection depend on speed sensor feedback. If faulty feedback remains active, false slipping or locking indication may continue.
