TRAIN CHIEF® II LRCS w/Lightweight OCU OWNER’S MANUAL
95-00-0-xxx Rev 000 6-3 Control Chief Corporation
• Idle: commands the throttle to idle, removes generator field, but does not apply
brakes.
• The remaining settings 1 – 8 command the same throttle settings as the control
cab console settings of the same number.
2. Power Switch:
Recessed Push-ON Push-OFF switch controls power to the OCU. Pressing the button applies
power to the unit from the battery pack and power bridge. Pressing the button again removes
power to the unit. Depending on the charge state of the power bridge, the OCU may initiate its
POST (Power-On-Self-Test) without an installed battery, but the unit will inhibit further operation
until a battery pack is installed.
3. Pitch:
This button is used to transfer LRC command to another OCU for “Pitch & Catch” operations
when Selective Dual Control is operational. Refer to page 4-2 in this manual describing the
Selective Dual Control feature.
4. Horn / Bell Switch:
This is a 3-positon switch. It is latched at the rear (OFF) position and at the center (BELL)
position. The forward (HORN) position is spring loaded to return to BELL position when
released. Return the switch to the OFF position to silence the Bell.
Specific to BELL function:
Whenever locomotive independent brakes are fully applied and
the Throttle selector is moved from Halt to some movement position, Train Chief® II sounds
the bell for 5 to 15 seconds. (Bell ringing durations are based on customer requirements for
their operation.)
Specific to HORN function:
The Horn function is used to acknowledge or accept a “Pitch”
from a transferring OCU.
5. Headlight / Extra Tilt Extend button: (options)
When the Headlight option is installed this button can toggle the state of the locomotive
headlights between DIM (default setting) and BRIGHT, or between ON and OFF. An indicator
on the OCU keypad will indicate the state of the control. See Chapter 5 for full explanation.
When the Tilt Extend option is installed this button will perform the same function as the F1
button on the keypad.
6. Audible Alarm:
The audible alarm provides a means with which to audibly prompt the operator of operational
status thereby enabling the operator to maintain visual attention on the task at hand. The
following table provides a description of the various alarm functions and their audible
indications.
