Both platform and ground

ously. Defaults to ground mode.
DESCRIPTION
The horn switch was closed dur-
ing power-up in platform mode.
The indoor / outdoor (zone A /
zone B) switch was closed dur-
ing power-up in platform mode.
The drive and lift inputs are
closed simultaneously in plat-

• Check that the elevation angle sensor is securely
mounted.
• Check the ANALYZER -> MACHINE SETUP -> MARKET
configuration.
• If MARKET is set to Japan, ensure ANALYZER ->
MACHINE SETUP -> DRIVE CUTOUT parameter is set as
desired.
Normal operation. No check necessary.
• Check key switch function.
• Backprobe J2-3 with the keyswitch in the ground
position. Voltage should be under 6V. Otherwise, key-
switch or wiring faulty.
• Backprobe J2-4 with the keyswitch in the platform
position. Voltage should be under 6V. Otherwise, key-
switch or wiring faulty.
• Check key switch wiring to ground board J2-3 and J2-
4 and to emergency stop switch.
• Replace ground board.
CHECK
• Check if the horn switch is damaged, obstructed or
jammed.
• Disconnect the horn switch ribbon cable on the plat-
form board. If DTC still present, replace the platform
board. If DTC 221 is no longer present, replace the
horn switch or platform board.
• Check if the indoor/outdoor (zone A / zone B) capacity
switch is damaged, obstructed or jammed.
• Replace platform board.
• Check drive/lift switch for visible damage.
• Check switch continuity. There should only be conti-
nuity from the center post to one of the outer posts at
a time. Otherwise, replace the switch.
• Check drive/lift switch signal and wiring to the plat-
form board. Its input (0V) is from platform board ter-
minal J1-11. "Lift" selection output (0V when selected)
is to platform board terminal J1-9. "Drive" selection
output (0V when closed) is to platform board terminal
J1-10.
