SERVICE MODE KEYBOARD FUNCTIONS
Technical Manual
Main display
The main display in the upper left corner normally displays the tubehead temperature.
The seven segments on the right side of the display indicate the sensor(s) signal(s). When
the sensor is active (magnet on the sensor) the segment is lit.
• Horizontal segments:
upper segment: up/down motor limit sensor
middle segment: temple rest motor limit sensor
lower segment: layer adjust motor limit sensor
• Vertical segments:
right upper segment: rotating arm end point limit sensor
left upper segment: rotating arm start point limit sensor
right lower segment: cassette holder end (return) point limit sensor
left lower segment: cassette holder start (ready) point limit sensor
If the system has detected an error the main display indicates the error number occurred. The
error is cleared by pressing CTL-key and the temperature display reappears. Also, similarly to
the normal mode, if the tubehead temperature exceeds 60 °C the temperature display blinks
and the exposures are not allowed and if it is not possible to make a new exposure due to the
X - ray tube cooling characteristics the blinking count down time is displayed.
Sector A indicator light
The sector A indicator light is used to indicate the cassette holder carriage start (panoramic)
point limit sensor operation. When the sensor is active (magnet on the sensor) this light is on.
(Only in Planmeca Proline EC Pan/Ceph X-ray unit)
Focal trough positioning keys are used to switch on the
positioning lights and to move the patient.
The rotation and cassette movements are not activated in
the service mode. “Focal trough position-
ing keys” on page B-8
kV setting keys are used to change the kV-value.
The display indicates the selected kV-value. During an
exposure the display indicates the actual kV-value mea-
sured from the X-ray tube. “kV keys and display”
on page B-8
mA setting keys are used to change the mA-value.
The display indicates the selected mA-value. During an
exposure the display indicates the actual mA-value mea-
sured from the X-ray tube. “mA keys and display”
on page B-8
Exposure time display shows the selected type of the X-ray
tube. “Exposure time dis-
play” on page B-9
