p, motor shall start. Does it start correctly jump to
11
. If not, does the motor operate in
Auto mode
? If yes, the
[U]
p button is broken, change Keyboard (KEX card). If not, the failure seems
to be Mainboard (MEX card), or motor failure. Check that the motor cables are not damaged or
unplugged. If the display shows the WEIGHT with 1-3 bars jump to
9
. If it shows high values, zero or
unstable values, the error may be due to any electronic cards. Change one at a time.
11. Line out
should count negatively (-001, -002, etc.) while wheel is rotating. If
no
The failure might be
on any cards, or something may happen with the magnets on the wheel. See Chapter
Sensors [E43
PP]
. If a new wheel has been fitted or the wheel has been removed, it may be wrong?
12. Press
[S]
op button. Attach the line to the Ex frame and start the engine. Increase
DRAG
slowly. Does
motor current and wheel power increase? If it is completely powerless, se
Clutch
below.
13. Does Sounder work when the buttons are pressed? If not the fault is on the keyboard (KEX card). On
the other hand, if it sounds weak, it may be because the bracket for amplifying the sound on the
keypad is missing.

Catch LED
menu, see Chapter Brightness [E3 PPP P]. Increase to 100%. If they do not
work the Keyboard (KEX card) must be replaced.
Emergency stop switch:
The emergency stop switch has a brace that need to be adjusted, else the two
problem may occur. If it’s correct, and power supply voltage is correct to machine, the problem might be
any of the electronic boards.
• Machine can’t be turned on. It’s totally powerless with dark display and Catch LED lights.
• Machine can’t be turned off.
Wheel stuck:
When Ex is powered off the wheel should be loose. If not may depend on...
• Mechanical: If wheel/clutch has been removed some washer might have been lost. Make sure the
washers both inside and outside of clutch rotor are mounted. Otherwise the rotor might have
mechanical contact to the clutch rotor, or the membrane plate got to tight space so it cant release the
wheel.
• Magnetic: The clutch may be permanently magnetized, dirty, rusted or corroded. Read about RP
Chapter [E45] to remove
P
ermanent
M
agnitization.
Clutch:
If wheel has no power when motor is running with
DRAG
set to 20% or more, the problem should
either be that Membrane plate is missing, or that Motor axle wedge is missing.
FAULT INDICATION
BATTERY LOW!
The battery voltage inside machine is too low. The alarm limit is below 10 volt. Note that if the machine is
plugged into a 24 volt system, 10 volts are very low. But Ex does is not sensitive to 12/24 system. It works
down to 10 volt wither way.
If
BATTERY LOW
indication appears in display, check cables, connectors, and boat battery. There is also
possibly that the machine measures the voltage wrong.
