Fault indication
When the ZePRO1 control card detects a fault, it displays a fault code on the display to assist troubleshoo-
ting. The fault code consists of a letter followed by a two digit number. The letter indicates the type of fault
and the number provides additional information about the fault.
Ifthecarddetectsseveralfaults,theyareprioritisedinthefollowingorder:L/H,E,F,UandA.Whenthecabin
switchisturnedoff,thesystemscrollsthroughalistofthelastveerrorsdetectedbeforethedisplayturns
off after approx. 5 minutes when the control card goes into sleep mode.
All fault codes can be reset manually by switching the cabin switch (if present) off and then back on again.
A-Internalfault
FaultcodeAisdisplayedwhenthecontrolcardhasdetectedaninternalfault.Insomecasesthetailliftcan
beusedasnormalwhenthiscodeisdisplayedaslongasitfunctionscorrectly.Iftheliftisnotfunctioning
correctly however, the control card needs to be replaced.
E - System locked
Fault code E is displayed when the control card is locked by a control device equipped with a locking fun-
ction, most commonly a radio control device or a spiral cable control device. The number following the letter
identiesthecardinputthatthedeviceusedtolockthesystemisconnectedto.ForexampleE1indicates
Ctrl1, E2 indicates Ctrl2 and so on.
Once a spiral control device equipped with a locking function has been used, the control system is locked
to the current control device until it is unlocked manually with the respective control device’s unlock button.
The radio control device is also equipped with a locking function. The control system can then be locked/un-
lockedbypressingandholdingthelock/unlockbutton.Intheeventofafaultintheremotecontrol,itcanbe
unlocked by turning the cabin switch off and then back on.
The fault code resets automatically if the control system has not received a signal from the relevant control
device for 6 minutes.
F - Output short circuit
Fault code F is displayed when the card detects an unusually high current draw through one of the outputs
whichimpliesashortcircuitonthatoutput.Thenumberfollowingtheletteridentiestheoutputinquestion
with 0-7 denoting output U1 through U7, the number 8 denoting the control device output section and the
number 9 denoting the sensor power output section.
The fault code is reset automatically when/if the card can detect normal current draw through the output.
H-Highvoltage
FaultcodeHisdisplayedwhenthecarddetectsaninputvoltagethatishigherthanexpected.Thenumber
followingtheHindicatesthemeasuredvoltage.Forexample,H32meansthatthemeasuredvoltageis32
Volts.
The fault code resets automatically once the voltage becomes acceptable again.
L - Low voltage
Fault code L is displayed when the card detects an input voltage that is lower than expected. The number fol-
lowing the L indicates the measured voltage. For example, L9 means that the measured voltage is 9 Volts.
The fault code resets automatically once the voltage becomes acceptable again.
U - Output not connected
Fault code U is displayed when the card powers an output with nothing connected to it. The number 0-7 fol-
lowingtheletterUidentiestheoutputinquestion,U0throughU7.
The fault code is reset automatically when/if the card can detect normal current draw through the output.
