SERVICE MODE DETAILED DESCRIPTION
Technical Manual
2.5 Suction holder related service modes
n 50 Show suction holder type and status for branch 1 (n. ¦
¦¦¦¦)
This service mode shows the suction hose holder sensor statuses and sensor PCB type con-
nected to the MCB branch 1 (normally the dentist's console suction hose holder). The three
(3) rightmost vertical bars represents the sensor statuses (hose in/out) from the three hose
sensors.
The fourth (leftmost) vertical bar shows the signal from the optional AUX input on the sensor
PCB (reserved for future use). A number 0 (zero) to the left indicates either that no suction
hose holder is connected to this branch, the cable to the hose sensor PCB is loose or faulty,
or that the sensor PCB itself does not respond. A number other than 0 (zero) shows that sen-
sor PCB is communication with the MCB. Currently only type 1 is in use.
n 51 Show suction holder type and status for branch 2 (n. ¦ ¦¦¦)
This service mode shows the suction hose holder sensor statuses and sensor PCB type con-
nected to the MCB branch 2 (normally the assistant side suction hose holder). See explana-
tion above.
n 52 Show left (high volume) suction sensor signal for branch 1
(nnn signal)
This is the direct sensor signal from the high volume hose sensor (leftmost) on the suction
hose sensor PCB connected to MCB branch 1 (normally the dentist's console suction hose
holder).
The display range is 0 to 255. When a hose is in the holder the display should be in the range
120...255, when no hose is in the holder the signal should be in the range 80... 200.
n 53 Show middle (saliva) suction sensor signal for branch 1
(nnn signal)
This is the direct sensor signal from the saliva suction hose sensor (middle) on the suction
hose sensor PCB connected to MCB branch 1 (normally the dentist's console suction hose
holder). See service mode n52 for further information.
n 54 Show right (ejector) suction sensor signal for branch 1 (nnn
signal)
This is the direct sensor signal from the ejector/assistant syringe sensor (right) on the suction
hose sensor PCB connected to MCB branch 1 (normally the dentist's console suction hose
holder). See service mode n52 for further information.
n 55 Show AUX input signal for branch 1 (nnn signal)
This is AUX input signal on the suction hose sensor PCB connected to MCB branch 1 (nor-
mally the dentist's console suction hose holder). This signal is reserved for future use and
shows always 255.
