ORTHOPANTOMOGAPH OP 2D 75
Error E5 (Line voltage out of limits)
CAUSE A
Line voltage too high or low.
SOLUTION A
The error code will clear automatically when the voltage
returns to its normal level.
If the voltage is not stable where the unit is being used,
you may have to install a voltage stabilizer.
CAUSE B
Line voltage has not been calibrated.
SOLUTION B
Calibrate the line voltage.
CAUSE C
Faulty cable(s).
SOLUTION C
Check cables and connections between
P1910 and L1500
L1500 and L1700
L1700 and L1200.
Replace any faulty cables or boards with faulty connec-
tors.
Error E7 (Opto or r-motor failed during r-movement)
CAUSE
L2100 or R5100 or rotating unit stepper motor is faulty.
The rotating unit cannot position itself correctly and
keeps on rotating, until the timeout (E 9) stops move-
ment, because L2100 is faulty.
The rotating unit does not move when the Return key is
pressed.
SOLUTION
L2100 can be checked by using the service command
"optotest", see section 5. S2terminal and Service
Functions .
The optotest command displays values that indicate
the position of L2100. When you manually rotate the
rotating unit the values should change, sector 0, sector
1, sector 2 and sector 3, which indicates that the op-
tosensors on the board are working and that L2100 is
functioning correctly.
If the values do not change, L2100 or the cable from
L1700 to L2100 is defective.
If L2100 is functioning correctly it indicates that there is
a problem with the stepper motor.
Check if R5100, the stepper motor or cable from R5100
to the stepper motor are faulty. Replace any that are.
