4 LOW BATTERY INDICATOR:
Blinking
– Battery Low. This is an indication that OCU operational time is limited. The battery
pack should be replaced with a freshly charged pack. The limited operational time during
LOW battery condition will vary based on ambient temperature, battery service time, and
usage. Operational run time in the LOW battery condition can range from 15 to 45 minutes.
Steady – Battery Dead. The battery dead condition indicates the pack has reached a
discharge level where continued operation cannot be assured reliable. When the OCU
detects this condition, operation will be inhibited and the OCU is placed in the lowest power
mode.
5 SOFTKEYS:
F1 = Tilt Extend. Under normal conditions this will extend the allowable Tilt time before
sounding Alarm. Also see page 4-9. To activate this command the operator must hold
the key in the Tilt Ext position for 2 seconds until the OCU sounds a BEEP to
acknowledge Tilt Ext has been activated. If the operator anticipates having to tilt the
OCU for more than a few seconds, pushing the F1 Softkey extends the allowable tilt
time to 60 seconds.
• Tilting the OCU more than 45-degrees turns ON an audible alarm for 3 seconds.
If the OCU is not restored to the upright position before this alarm finishes, the
OCU sends an Emergency Locomotive Stop command to the locomotive.
• If the OCU remains in the tilted condition for more than one minute the Man
Down Alarm will become activated. Refer to Man Down Alarm (page 4-9) for
more details.
