Flashing LEDs Additional patterns with flashing of the LEDs indicate a problem with the
MPS-4007 Power Supply. Please see “Troubleshooting” in “Maintenance
and Storage” below for additional information.
Charge Time Charge time for fully depleted batteries depends on the amount of load
connected to the power supply.
Typically it takes about 4 hours to fully charge a completely depleted
battery, if the load of cart electronics is less than 30 Watts. For a greater
load, charging will take longer:
Examples:
1. Workstation electronics load is in a range greater than 30 Watts. The
power supply can only charge 7 of 8 battery packs in 4 hours. After 4
hours, the charged indication will be 85%. The remaining battery
pack will charge fully in 4 more hours for a total charge time of 8
hours.
2. Workstation electronics load is in a range greater than 110 Watts.
The power supply can only charge 4 of 8 battery packs in 4 hours.
After 4 hours, the charged indication will be 50%. The remaining 4
battery packs will charge fully in 4 more hours for a total charge time
of 8 hours.
Upon completion of the charge cycle, all 5 amber LEDs will be illuminated
and the green CH (charge) LED will turn off, indicating that the batteries of
the power supply are fully charged.
Notice:
Extended
Storage If the Mobile Computing Workstation will not be used for an extended
period of time, ensure the ON/Extended Storage Switch is set to the
“Extended Storage” (OFF) position. If the power supply is left in the “ON”
position, the workstation equipment will continue to draw power and deep
discharge the battery.
Notice:
Long Term
Storage (Longer
than one week)) If the Mobile Computing Workstation is to be placed in long term storage
(longer than one week), the Power Supply should be fully charged before
placing the “ON/Extended Storage” switch in the “Extended Storage”
(OFF) position.
Notice: MPS-4007 Li-Nano Power Supply enters sleep mode after one
week in Extended Storage.
If the MPS-4007 Li-Nano Power Supply has been switched to “Extended
Storage” (OFF) for more than 1 week, connect the workstation to AC to
wake up the power supply before switching it to “ON.”
Warning: Risk of Electric Shock
The Power Supply employs a Li-Nano battery to provide mobile DC output
power. Low voltage (10-16 VDC) DC power is available from the Power
Supply even when the AC cord is disconnected from an AC outlet. To
remove DC power, put the ON/Extended Storage Switch in the “Extended
Storage” (OFF) position.
