Hallo an alle.
Ich hab ein Problem mit meiner Geodyna 85M.
Nachdem die Maschine nach Transport Fehlermeldungen angezeigt hat (e54,e64) hab ich mal alle Steckverbindungen kontrolliert. Sah Anfangs alles gut aus. Trotzdem waren die Meldungen dann weg und e70 tauchte auf. Dieser Fehler verschwand genauso wie er kam,...
Jetzt ist folgendes. Wenn ich die Maschine einschalte erscheint im Display 813 was wohl normal ist. Dann geht's weiter zum einstellen der Reifendimensionen.
Und hier beginnt mein Problem. Beim Reifendurchmesser erscheint direkt "24" ohne was eingegeben zu haben.
Wenn ich auf die Felgenbreite drücke.wird Null angezeigt und bei der felgenbreite gleichzeitig erlischt das "Inch" Lämpchen.Beim drücken auf Felgendurchmesser ist es genau umgekehrt. Einstellen kann ich absolut nichts.
Hat irgendjemand eine Ahnung was das sein könnte?
Achso als die ersten Fehlermeldungen kamen,konnte ich die Dimensionen noch einstellen.
Schon mal vielen Dank im voraus.

E54/64 schliessen auf Spannungsverlust an/auf der Platine (24V)
E70: Distance gauge defective (40 Limited Edition / 80 Series Only)
a) The potentiometer slider voltage of the distance gauge is less than 0.1 or
more than 4.9 volts.
b) After pressing the STOP button it is possible to balance wheels with
dimension input via the keyboard.
c) For precise trouble shooting, enter the test code "C50C" and check the
following items:
1) Is the gauge in its rest position?
2) Is the gauge calibrated?
3) Is the connector on interface board plugged?
4) Does the voltage on the potentiometer slider increase steadily while
moving the gauge lever?
If items 1 to 3 are O.K., but the error code is displayed again after
power on, replace the potentiometer and adjust the gauge.
5) Is the handle lever from the distance gauge off?

Soviel dazu :-)

Wow, danke mal dafür.
Werde das mal überprüfen und testen.
Haben Sie evtl. Irgendwelche Dokumente zu der Maschine?

[Spannungsprüfer132776]

@tgenius,
Gibt es da eine Tabelle oder sowas mit den Codes die man überprüfen kann und welche Werte angezeigt werden müssen?!

[Spannungsprüfer135689]

Ja

E0 Keyboard entry of a non-existent error code.
E1 with ? display
Rim distance setting is impractical for balancing using the selected ALU 2 or 3
mode. The distance between the rim center flange and left correction plane
is too narrow.
E1 with ? display
Rim width entered is out of range.
E1 with ? display
Rim diameter entered is out of range.
E2 Wheel guard is not closed.
E3 Distance gauge is not in the rest position.
E4: Width gauge is not in the rest position.
Symptom: After pressing start key an E3 and/or E4 appears
Cause / Remedies: On a machine with automatic distance, diameter and/or rim width
gauges these codes occur because one of the gauges is not in the rest position. See
Adjustment codes C80C, C81C, C82C.
On a machine without automatic measuring gauges these codes can be caused by a
defective processor board, interface board. Or a micro residue build up on the interface
board. Replace Defective board.
E5: Wheel is too far out of balance for zero balance compensation during function
code C4, or calibration weight was inserted by mistake during CAL 1.
E6: Calibration weight was not inserted during Cal 2 step of the user calibration - or
both pick-ups are disconnected.
E7: ALU mode was selected after rim dimensions have been entered in mm.
Dimensions must be entered in inches (width & diameter) to use the ALU modes.
E8: During tire matching the valve position was not entered.
E9: Tire matching error:
• An error was made following the procedure.
or
• The wheel was incorrectly centered on the adapter.
or
• The tire was incorrectly mounted on the rim.
E15: During operator calibration: ( C14C )
The correction factors used for calibration are incorrect.
Causes:
1. The Geodyna 40/60/80 Series uses a wheel adapter that is different than
many earlier model Hofmann balancers. The machines use a longer threaded
center sleeve. The backing plate (the surface the wheel presses against) is
extended about 3/4" from previous versions.
Both types of wheel adapters can be used but it is necessary to set the Distance
Gauge Adjustment to match the adapter used. See Adjustment, Distance
Gauge. Follow instructions using code C 80 C. Also Readjust using codes
appropriate for each balancer model C81, C82, C83, C84. The value determined
must be stored in the memory, see Store Adjustments in Memory.
2. The Pick-up output voltage has changed. Check and replace pickups if
necessary.
3. There may be a wheel weight lodged in or along side the vibratory structure.
E30: The shaft did not reach measuring speed within 120 revolutions. Check the
drive motor, Opto electronic using codes C54 & C74.
E31: The balancer shaft attempted to turn in the wrong direction.
Check the drive motor connections, and start capacitor.
E34: Phase difference between Pick-ups is more than 3°. See codes C61, C65 & C75.
1) Check the Pick-up connections at the Interface circuit board. Are they
connected to the correct terminals?
2) Check that the Pick-ups are tightly mounted under the shaft in the
Vibratory assembly.
3) Check that the four vibratory assembly mounting bolts are tight.
4) Replace the Pick-ups one at a time.
Note: The display is the phase difference found during the last C83 adjustment. In
order to display another value it is necessary run C83 again after replacing each
Pick-up.
E35: Left Pick-up output voltage does not correspond to rim width or distance
settings during code C83 adjustment. See E36 for troubleshooting.
E36: Right Pick-up output voltage does not correspond to rim width or distance
settings during code C83 adjustment.
To trouble shoot:
1) See Code C61C
2) Check that the actual rim width (use Hofmann calipers), and distance has
been set. Has the C80 procedure (rim distance adjustment) been properly
followed?
3) Check that the machine is sitting solidly on the floor and only resting on the
three mounting pads. Tilt the machine back to check underneath for wheel
weights, etc.
4) If the machine is bolted to the floor make sure either all bolts are tight or all
are loose to eliminate the possibility that one mounting pad is not solidly
touching the floor. It is best to loosen all three mounting bolts and tilt the
machine back to check for anything under the machine.
5) Check for a wheel weight lodged in or along side the vibratory structure.
6) Check the Pick-up connections at the Interface circuit board. If E36
displayed with E34 it's likely the problem is a defective pick-up.
7) Check that the Pick-ups are tightly mounted under the shaft in the vibratory
system. They should not turn by hand.
8) Check that the four vibratory system mounting bolts are tight.
9) Try C83 Readout adjustment again using another wheel and tire assembly
or only a wheel. If C83 adjustment was attempted using a thick alloy wheel try
adjustments again using a steel wheel.
E50: Eprom defective. The Eproms are mounted on the Processor circuit board
sockets ROM 1 and ROM 2 and are field replaceable. When this error code
appears both Eproms should be replaced.
E51: Ram defective. The Ram is not field replaceable - replace the Processor
circuit Board.
E52: Left A/D Converter defective. The A/D converter is not field replaceable -
replace the Processor circuit Board.
E53: Right A/D Converter defective. The A/D converter is not field replaceable -
replace the Processor circuit Board.
E54: Power supply to the machine measured at the Processor circuit board is low.
See Error Diagnosis section C55.
E55: Power supply to the machine measured at the Processor circuit board is high.
See Error Diagnosis section C55.
E56: A/D reference voltage incorrect. Replace the Processor circuit board.
E58: Processor circuit board error, PIO. Replace the Processor circuit board.
E60: Display error. One of the seven segment displays or LED's is defective.
Replace the Display circuit board.
E61: Start, stop or keyboard key is stuck closed. Can be the Display circuit board or
the Processor circuit board defective. If replacement of either board is necessary
connect a wire from the panel ground to the machine chassis ground. Use a
panel circuit board hold down stud.
E62: Memory defective. Replace the Processor or Interface circuit board. If a
replacement board is not at hand adjust the machine following adjustment
procedures, then leave the power on until the defective part can be replaced.
E63: Adjustment &/or function code data memory on Interface circuit board is
incorrect. When the power is switched on the computer program transfers stored
data from the Interface circuit board data memory to the Processor circuit board
memory. If an error is detected code E63 displays. It is possible this error can
occur because of loss of stored data caused by large voltage variations in the
balancer power source. This could occur during lightning storms or by power
distribution problems. Readjust and set function codes. If E63 reoccurs replace
the Interface circuit board.
E64: 24 vdc is not available on the Interface circuit board. Check the 0.8 amp fuse
on the Interface circuit board. If the fuse continues to blow there can be short at
one of the contactor coils. Disconnect one at a time to trouble-shoot. The
problem may also be the Interface or Processor circuit board.
E65: Power supply voltage to the Processor circuit board dropped too low during
the balancing cycle to ensure accurate readings. Measure the line voltage,
connections to the balancer and the internal connections. See code C55.
E70: Distance gauge defective (40 Limited Edition / 80 Series Only)
a) The potentiometer slider voltage of the distance gauge is less than 0.1 or
more than 4.9 volts.
b) After pressing the STOP button it is possible to balance wheels with
dimension input via the keyboard.
c) For precise trouble shooting, enter the test code "C50C" and check the
following items:
1) Is the gauge in its rest position?
2) Is the gauge calibrated?
3) Is the connector on interface board plugged?
4) Does the voltage on the potentiometer slider increase steadily while
moving the gauge lever?
If items 1 to 3 are O.K., but the error code is displayed again after
power on, replace the potentiometer and adjust the gauge.
5) Is the handle lever from the distance gauge off?
E 71: Rim diameter gauge defective (40 Limited Edition / 80 Series Only)
a) The potentiometer slider voltage of the diameter gauge is less than 0.1 or
more than 4.9 volts.
b) After pressing the STOP button it is possible to balance wheels with
dimension input via the keyboard.
c) Enter the test code "C51C" and check the following items:
1) Is the gauge calibrated?
2) Is the connector on interface board plugged in?
3) Does the voltage on the potentiometer slider increase steadily while
turning the gauge lever?
If items 1 to 2 are O.K., but the error code is displayed again after
power on, replace the potentiometer and adjust the gauge.
E 72: Rim width gauge defective (80.E Series Only)
a) The potentiometer slider voltage of the rim width gauge is less than 0.1 or
more than 4.9 volts.
b) After pressing the STOP button it is possible to balance wheels with
dimension input via the keyboard.
c) For precise trouble shooting, enter the test code "C52C" and check the
following items:
1) Is the gauge in its rest position?
2) Is the gauge calibrated?
3) Is the connector on the interface board plugged in?
4) Does the voltage on the potentiometer slider increase steadily
while moving the gauge lever?
If items 1 to 3 are O.K., but the error code is displayed again after
power on, replace the potentiometer and adjust the gauge.
E73: Transmitter (IR LED) of Opto electronic defective. Test using codes C54 &
C74 & C75. Opto electronic, Processor board may be defective.
E74: No pulses are measured from the Opto electronic. The Processor circuit
Board does not recognize that the balancer shaft is turning. Does the shaft
turn? If yes, test using codes C54 & C74. Opto electronic or Processor circuit
board may be defective. If not, the error code is not caused by the Opto
electronic. Check the power to the machine, internal electrical system, motor
relay, fuses and connections. If the motor can be heard turning but the balancer
shaft does not, check the drive belt and tension assembly. If the motor hums
only and E74 comes on after a few seconds, it may be a defective start
capacitor. It may be also a incorrectly wired wheel guard switch, especially if the
C13C code is set to 1.
Remedy: Replace wheel guard switch
E76: Left Pick-up reference voltage incorrect. To trouble-shoot see E77.
E77: Right Pick-up reference voltage incorrect. To trouble-shoot:
1. Switch the power off. Unplug both Pick-ups from the Interface circuit board.
Switch the power on. If E76/77 still displays replace the Interface circuit board.
If not go to 2.
2. Switch the power off. Plug the left Pick-up into the right terminal and the
right Pick-up into the left. Switch the power on. If the error code follows the
Pick-up replace the Pick-up. If not replace the Interface circuit board.
Symptom: After turning on power E76 and/or E77 appears.
These error codes indicate a wrong D.C. voltage on the left and/or right transducer
(Pick-up). These voltages can be observed using code C75C then press #5. The proper
voltage should be 2.50 +/- 0.05 volts.
Cause: These error codes can be caused by a defective interface board or a build up of
film on the board. The latter fault will become evident in very humid conditions.
E78: Incorrect output is measured from the left Pick-up. See code C75.
Left Pick-up, Processor or Interface circuit board may be defective.
E79: Incorrect output is measured from the right Pick-up. See code C75.
Right Pick-up, Processor or Interface circuit board may be defective.
E80: Basic calibration data was not found in the memory. Can be that steps 5 and 6
were not stored in the memory during basic adjustment (C83). Reset the
Function codes and then follow the adjustment procedures, C83 & C84. If error
code E80 repeats replace the Interface circuit board.
E136: Computer data line defect. Check ribbon cable to Processor board (loose plug).
Replace the Processor or Interface Circuit board.

Servus,

Ich habe eine Geodyna 35, also etwas älter.
Sie zeigt Fehlercode E80 beim Versuch der Kalibrierung an. Weiß jemand wie sie Grund-Kalibrierung durchgeführt wird?
