TRAIN CHIEF® II LRCS w/Lightweight OCU OWNER’S MANUAL

Tilt Extend
The tilt extend is provided to facilitate operator tasks requiring two hands.
To extend the tilt timeout the independent brakes must be applied.
¾ Set the Throttle selector to HALT.
¾ Press the F1 push button on the keypad until the OCU acknowledges the request with a
beep then release F1.
¾ The operator has 60 seconds to perform tasks while tilting the OCU.
¾ The Tilt Extend is canceled when the operator moves the Independent Brake from the
FULL application selection or moves the Throttle Selector out of HALT.
Man Down Alarm
When the tilt function has been active for more than 1 minute the locomotive horn will begin to
cycle on and off or sound continuously depending on your site operating rules.
The alarm will continue to be active until the receiver/controller is reset.
If the OCU is returned to its normal operating position before the man down timer expires the
alarm will be cleared.
To recover from Man Down Alarm: recycle power on the RCU and OCU. Then perform initial
setup procedures. See Chapter 4.
Emergency brake Applications
In emergency situations, emergency brakes are activated by pushing in the RED Mushroom
push button next to the reverser switch. This action causes the OCU to send an operator
Emergency Stop command. The controller will respond by commanding an Emergency
Locomotive Stop.
To recover from an operator Emergency Stop, pull-out the Red E-stop mushroom push button,
Throttle selector to HALT, Independent Brake to FULL.
Train Chief® II will also apply emergency brakes when a serious fault occurs in the system.
In either case, Train Chief® II quickly opens the Brake pipe to apply emergency brakes to both
locomotive brakes and trainline.
¾ When operating with dual OCU’s in Selective Dual Control operation, the locomotive will
accept an Emergency Stop command from either OCU at any time.
Note: An emergency brake application completely drains (dumps) the brake pipe on all
cars. Recharging times will vary greatly depending on the number of cars connected
and weather conditions.
Operating under winter conditions
During winter conditions, brake components may get covered with snow or ice and braking
power may be reduced. Therefore, during these types of conditions, make regular brake
applications to keep the braking components working properly.
¾ With the locomotive moving at a speed of no greater than 4 mph (6 ft/sec), apply a small
amount of brakes by moving the Independent Brake selector to Low position. This
allows friction to melt away snow and ice on the shoes and wheels.
