Diagnostic Display - Clark ESX Series Operator's Manual

Diagnostic Display

The standard diagnostic display indi-
cates the operating hours registered
on the truck, a scale of usable charge
left on the battery, fault codes, speed
reduction indicator and a LED that
indicates when the tilt is outside of the
restricted tilt range. The hour meter
or fault codes display when the key
switch is ON. The hour meter reading
is indicated along with the hour glass
symbol and an alarm is indicated along
with the wrench symbol. If the truck is
operating in a speed reduction mode,
the turtle indicator will be present.
Your truck has a Diagnostic Display. "88888" should display on the digital
readout for about one second after you turn the key switch to ON. This
indicates that the digital readout is OK. After one second, either the hour
glass symbol or the wrench symbol should come on.
If the hour glass symbol comes on, the digital readout shows the truck
operating hours. If the wrench symbol comes on, an alarm code appears
on the digital readout. The alarm code may indicate an easily correct-
able "operator fault" or it may indicate that you need to have the truck
serviced.
The battery state of charge scale is divided into 10 segments indicating
every 10% of battery charge. When the gauge registers 10% (one LED),
the lift, tilt, and auxiliary functions become inoperable and the truck's travel
speed is greatly reduced. At this point the battery will be 80% discharged.
Charge or replace the battery immediately.
If you see an alarm code, use the table below as a guide. The codes
listed below are usually the operator alarm codes (faults). Any other code
is a service code.
