TRAIN CHIEF® II LRCS W/ Lightweight OCU-BT – OPERATORS MANUAL
95-00-0-062, Rev 09 4-14 Control Chief Corporation
4.5.12 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.
o 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.
4.5.13 Active and Maintain Communication Modes
• During normal operations, when the operator is actively commanding the locomotive,
communications with the controller occurs at an active rate. In this condition, as
indicated by fast flashing of the OCU A or B indicator, communication occurs at a fast
rate to ensure a fast response to the operator’s commands.
• If the position of the control switches or selectors are not changed for some time (about
six (6) seconds), then communication is switched to a slower “maintain” rate to conserve
battery power.
o The slow blinking of the OCU A or B indicator shows the maintain rate.
o If any control switch or selector is moved, while communications is at a maintain
rate, the active rate is immediately activated to restore fast operator response.
