Cycle the key switch to start the lift truck in
the normal mode. Operate the lift truck until
the alarm code reoccurs (faults out). Then, go
back to the Alarm Code menu and write down
the alarm codes which are now present. These
alarms should be investigated first to isolate
the most prominent malfunctions.
NOTE:
If the THERMAL PROTECTION alarm co-
des are generated, use the Tester Function = Tem-
perature. If the controller sees 75°C (175°F) or be-
low −10°C (14°F), it will reduce electrical current to
the motors and regular performance of the lift
truck will slow down.
You can operate the truck with the Tester Func-
tion activated and monitor the controller's inter-
nal temperature in real time. For additional heat
dissipation, fold up several layers of aluminum
foil and place it between the controller mounting
base and the mounting plate to fill any air pock-
ets in the mating surfaces which will impede
conductivity and prevent the heat from flowing
from the controller heat sink into the mounting
plate of the controllers. The use of "conductivity
paste' is not recommended.
CAUTION
If the battery has been disconnected and recon-
nected with the key switch in the ON position, a
voltage spike can cause corruption of the Zapi
controller EPROM.
Remember to use the "Tester" function to check
switch input from the control handle to the con-
troller. This procedure will also alert you if the
controller has been changed but the control han-
dle card has not been reprogrammed.
Zapi controller menu items:
• ACCELERATOR = Volts Percent % =
Shows Variable Voltage From Traction
Thumbwheel (FWD or REV)
• FORWARD AND BACKWARD SWITCH =
"OFF to "ON"
• LIFTING CONTROL = Volts Percent % =
Lifting and Lowering = Proportional
Switches (Control Handle Card Must be
Calibrated)
• LIFTING AND LOWERING SWITCH =
"OFF" to "ON"
• BELLY, HORN, SNAIL SWITCHES =
"OFF" to "ON"
• SW8 = Gray Button for Alt Functions =
