WHEEL GUARD SWITCH
• C56 - Check the wheel guard switch. The switch and the Function-Code should be checked if the balancer will
not spin the wheel or if E89 is displayed Check the pedal switches. The switches and the Function-Code to lock
the power clamp should be checked if the power clamp does not work.
TEMPERATURE SENSOR
• C57 - I
ndication of temperature.
ELECTRIC MOTOR
• C60 -
Indication of RPM of main shaft
LASER POINTER STATUS
• C123 - Weight laser board status
VPM CALIBRATION STATUS
• C59 - I
ndication of the residual unbalance compensated for using code C84
• C63 - Continuous measurements for test of valid results.
• C64 -
Indication of the transducer sensitivity as measured with C code 115
• C67 - Indicate the phase stability/shift of the vibratory system
• C71 - Display angular deviation of the vibratory system as measured with C code 115.
• C72 - Measure the angular deviation of the vibratory system
• C75 - Check Voltages of piezo transducers (AeD1, AeD2).
• C103 - Test of transpindence and unbalance signal ampli! ers.
• C104 - Test of transducers.
SONAR CALIBRATION
• C82 - Sonar sensor calibration
5.6 SELFTEST DURING STARTUP
A series of tests is accomplished after the machine has been turned on. If a test is not successful:
• A series of audible signals is given
• An error code is read out.
A three-tone signal is given once if the machine is operative.
In case there is a functional error it must be acknowledged by pressing the STOP key and there is no three-tone
signal.
E9 Wheelguard is not open, wheel may not be clamped/unclamped
Complaint Wheel clamping or unclamping is not allowed with the wheel guard lowered.
Root cause
Wheel guard lowered.
Wheel guard switch cable disconnected from the Integrated Display
Service Code C56
Actions to do
Raise the wheel guard for Wheel Clamping or unclamping
Make sure abou the proper connection of the wheel guard switch cable
