Controller Safety
WARNING
The ZAPI™ controllers can hold an electrical
charge for several minutes after the key switch
has been turned OFF. To prevent injury, discharge
the controllers by connecting a 200-ohm, 2-watt
resistor between the battery positive connector
and battery negative connector on the controller
and hold there for 5 seconds.
See Figure 2.

Controller Adjustments
The ZAPI™ transistor motor controller can store
and display Error Codes (Alarms). It is also possi-
ble to modify the controller Setup for individual
preferences. Communication with the controller is
possible by four methods:
1.
LED - An LED (light emitting diode) can be in-
stalled in trucks that do not use a display. The
LED flashes error codes to the technician for di-
agnosis. The LED would be installed on the bot-
tom of the ZAPI™ controller at connector port
D. See Figure 1.
2.
Dash Display - Some trucks are equipped with
an optional dash display or MDI. Error codes
are shown on the LCD (liquid crystal display)
when the wrench symbol and red light are lit.
The format is AL XX where XX is the error
code. The software version is displayed on
startup.
3.
ZAPI™ Handset - A diagnostic handset is
available through your Hyster dealer. The
handset makes it possible to diagnose faults
and modify controller settings. See Program-
ming, in this section.
4.
Personal Computer - The controller can also
be connected to a personal computer (PC)
equipped with special software and cables. The
PC can read, store, and change settings on the
controller.
