2200 YRM 1067 Modes of Operation
Controller Adjustments
The ZAPI™ transistor motor controller can store and
display Error Codes (Alarms). It is also possible to mod-
ify the controller Setup for individual preferences. Com-
munication with the controller is possible by four meth-
ods:
1. LED - An LED may be installed in trucks that do
not use a display. The LED can flash error codes
to the technician for diagnosis. The LED would be
installed on the bottom of the ZAPI™ controller. On
the MPW045/050-E, connector port D is used. 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 Yale dealer. The handset makes it
possible to diagnose faults and modify controller
settings. See Programming, 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.
Proper use of these four methods and a list of diagnostic
codes are explained in Troubleshooting, in this section.
Modes of Operation
It is possible to adjust the operating characteristics of
the lift truck. There are two basic ways to do this: User-
Selectable and Non-User-Selectable Operating Modes.
USER-SELECTABLE OPERATING MODES
The operator has a choice of three performance modes
that are selectable through the control handle. The
mode selection is made at startup or key ON.Perfor-
mance parameters that vary are acceleration, decel-
eration, regenerative (neutral) braking, and top travel
speed.
The three operator-selectable performance modes are
factory programmed per the following:
• Mode 1 - Economy mode (battery saver) - soft accel-
eration, reduced top speed with regenerative (neutral)
braking.
• Mode 2 - Performance with regenerative (neutral)
braking - medium acceleration, reduced top travel
speed with regenerative (neutral) braking.
• Mode 3 - Performance without regenerative (neutral)
braking - maximum acceleration, maximum top travel
speed with coast at throttle release.
The following procedure is used to access the user-se-
lectable operating modes:
1. The controller drive modes parameter must be ON.
This is the factory setting.
NOTE: You must use the handset or PC interface to
change this setting. Using the ZAPI™ handset or PC
connection, it is possible to set the drive mode parame-
ters to ON or OFF. In the ON mode, the user-selectable
rules are enabled. In the OFF mode, the lift truck will
only operate using the settings selected. The proce-
dure to alter or modify these settings is given in Pro-
gramming in this section.
2. Control handle must be in the full, upright position,
brake ON.
3. Press and hold the horn button while turning the key
switch to the ON position.
4. Release the horn button when the horn sounds.
5. Toggle through the modes by pressing the lift or
lower buttons to the desired mode.
6. The horn provides an audible indication as to the
mode selected. One beep indicates Mode 1, two
beeps indicate Mode 2, and three beeps indicate
Mode 3.
7. Lower the control handle to the operating position,
brake OFF, and begin operation.
8. The selected mode is maintained until the proce-
dure is repeated.
9. Tu r n in g t h e key OFF before lowering the control
handle will cancel the mode change.
