SERVICE MODE DETAILED DESCRIPTION
Technical Manual
n.80 Backrest mechanism position sensor calibration mode
(b --)
This service mode is used to calibrate the backrest potentiometer. This needs to be per-
formed if the pot is loosened from the motor or if the motor is replaced. Press the S key for 8
seconds until the LED in the key lights. Use the C and D keys to first align the two marks in
the mechanism. Loosen the potentiometer cogwheel and turn the pot axle until the segments
align in the display. Tighten the cogwheel. For more detailed calibration instructions, please
refer to 2.1 “Calibrating backrest motor position sensor” on page F-18.
Note that during the calibration of the backrest motor position sensor all software limits are
ignored. Special care must be taken for not to damage the unit by driving the backrest to its
mechanical limits.
2.9 Separator/suction system related service modes
n 81 Show type of installed suction system (n mode = 0, 1, 2, 3,
4...)
This service mode displays the type of installed separator system (if any). The type of the
separator system is automatically determined by the type of separator cable connected to the
MCB (jumper wires).
0 = wet suction system or no separator system installed
1 = Microvac II dry suction system separator (manufactured by Planmeca, no amalgam sepa-
ration)
2 = Dürr Combisep amalgam separator (manufactured by Dürr, centrifugal amalgam separa-
tion)
3 = Metasys (manufactured by Metasys, centrifugal amalgam separation)
4 = VSA suction motor/amalgam separator combination (manufactured by Dürr, stand alone
system)
5..7 = reserved
n.82 Set suction motor turn-off delay (n mode = Cont, 00.03...
30.00)
This service mode sets the turn-off delay for the suction motor controlled (optionally) by the
unit. The factory default is 00.03 (three seconds). This turn off delay protects the suction
motor from repeated start /stop cycles. Setting the mode to “Cont” (continuous) would start
the suction motor immediately when the unit is turned on, and turn off the motor automatically
when the unit is turned off. Any other setting would keep the suction motor running as long as
indicated, after the suction hoses are put back to their holders.
The turn-off delay for the suction hoses is used also for the Dürr spittoon bowl valve.
n.83 Set number of suction hoses / disable suction system (n
mode = 0, 1, 2, 3)
This service mode tells the unit how many simultaneous suction hoses are installed in the
unit. The unit needs to know this detail so it can determine when to turn off the suction system
and the suction motor. The following settings are possible:
0 = no suction system installed (no suction hoses, ignores all related possible error mes-
sages)
(used also with independent suction system)
1 = one suction hose only
2 = two suction hoses (factory default)
3 = three suction hoses (mainly USA, using extra T-branch adapter)
