Control Card Functional Test 2200 YRM 1067
Control Card Functional Test
Refer to Figure 5 for the following procedures.
1. Follow all safety precautions as listed at the begin-
ning of this section prior to performing any electrical
checks.
2. Ensure Battery is fully charged.
a. Verify continuity between battery negative (at
battery) and
B terminal (at controller).
3. Check for loose connections or damaged wiring be-
tween control card and controller.
a. Verify connection at the controller.
b. Very wire harness connection at the base of the
steer handle.
4. Connect ZAPI handset and go to tester function.
Refer to ZAPI™ PC Interface in this section.
NOTE: If ZAPI Handset can not be connected, consult
LED OFF. See Troubleshooting in this section.
5. With ZAPI Handset connected, check the following:
a. Look for battery voltage to be 25 ±0.5 volts.
b. Check for accelerator output to be 95% or more
at full throttle, and to be at 0% and 0V on neutral
position.
c. Check for lift switch, fork low switch, belly
switch, and horn switch to alternate between on
and off when switch is pressed and released.
(Ensure belly switch is properly seated.)
(1) If ON-OFF lift/lower switches doesn’t be-
have as expected, swap the On-Off switch
with other On-Off switch available within
tiller head to verify if problem follow the
switch.
d. Check lifting control to be more than 90%.
(1) Output of proportional hydraulic controls
should be less than 10% at neutral.
(2) If Proportional lift/lower switches doesn’t
behave as expected, swap the pro-
portional switch with other proportional
switch available within tiller head to verify
if problem follow the switch.
6. If handset test are not passed, open tiller head and
verify connection at control card:
a. Power off the forklift and measure continuity
between pin 2, on JP2, on the control card and
B- at the controller.
(1) If an open or high resistance is measured,
trace problem source and refer to Trou-
bleshooting in this section.
b. Power on the forklift and check for 7- segment
LED to light on.
(1) If the LED is not lit then check to have
power on JP2, between pin 1 and pin 2.
i. JP2 voltage reading shall be 14V
or more, if not, then the tiller card is
not receiving power from controller.
Disconnect the connection at JP1
and verify the voltage between har-
ness pins 1 and 2 is more than 14V.
a. Check the wiring between the
controller and the tiller card, as
well as the controller output.
b. Measure voltage at pin 5, on
connector C, on the ZAPI con-
troller.
The voltage should be
12V with card disconnected and
3V to 9V with control card con-
nected.
If voltage is different,
please refer to Troubleshooting,
LED Off sections.
c. Measure voltage at pin 7, on
connector C, on ZAPI controller.
It should have 22V or greater
with card disconnected. If volt-
age is different, please refer to
Troubleshooting, LED Off sec-
tions.
d. Reconnect and measure voltage
on JP2 again.
ii. If voltage reading is achieved on
JP2, and the 7 segment display is not
lit, replace the tiller card. Refer to
the section
Electrical System 2200
YRM 1007.
(2) Ensure jumper on SV2 is not on Diag-
nose, Teach or Configuration mode. SV2
jumper can be either seated on parking
position (P) or not present at all.
