CURRENT STATUS DISPLAY
CURRENT STATUS DISPLAY
SET SPEED MAX.
Calibrates the speedometer and odometer of the chair. The value is maximum speed of
the chair in mph or kmh. Refer to the chair specification for this value, as motor type,
gear ratio and wheel diameter all affect maximum speed. Use the  and  to set the
value to match the chair maximum speed.
V. CURRENT STATUS DISPLAY
The Current Status display is a diagnostics tool that shows the function of major sys-
tems within the MK5. The first screen(s) give type and performance of the driver input.
Moving the driver control reveals its operation. A normally calibrated joystick will
achieve nearly 100 in each axis direction. A short throw setting will show that 100 is
achieved before the mechanical restrictor is reached.
NETWORK CONNECTIONS show which displays or options are connected to the
MK5 system. If one is missing, it means the control module cannot communicate to it.
Check the connector and wiring to the device. It may need to be replaced.
SOFTWARE VERSION gives software version number in the control module.
BATTERY VOLTAGE displays the current battery voltage. A low voltage may
indicate battery problems. Charge the batteries and recheck chair performance.
LOAD TEST shows the results of the most recent battery load test. GOOD means
the batteries are fine. Poor means the batteries may affect the performance of the chair
under heavy loads, but do not need to be replaced yet. BAD means the chair perfor-
mance will be affected even immediately after recharging and that they should be re-
placed. UNK (Unknown) means that the conditions for a load test have never been met
and the test has not been performed.
DRIVE LOCKOUT demonstrates the current state of the drive lockout/charge inhibit
input. The function of the input cannot be displayed when the programmer is plugged
into the charger port. Move the programmer to the 5 pin connector input.
M2 ROLLBACK shows the value of the M2 motor current rollback parameter as a
percentage of its maximum value. High values are indicative of recent high stress or
load on the motor. See Section XI Current Rollback for causes and methods of reduc-
ing current rollback values.
M1 ROLLBACK shows the value of the M1 motor current rollback parameter as a
percentage of its maximum value. High values are indicative of recent high stress or load
on the motor. See Section XI Current Rollback for causes and methods of reducing
current rollback values.
TEMPERATURE shows the internal control module temperature in degrees C. Room
temperature is approximately 20-25
o
C. High values (above 50
o
C) indicate recent high
stress or load on the control module.
READY TO DRIVE indicates YES if there are no current faults or error codes de-
tected. The E code will be given if there is a current code.
ODOMETER indicates miles/km driven by the chair.
