SERVICE MODE DETAILED DESCRIPTION
Technical Manual
n 1 Show software version on MCB (n.nn.n version)
Shows the currently installed software version on the MCB. Shows normally version number
(“3.02.5” ie. 3 = Major version, 02 = minor version and 5 = fix version). When in Set-mode,
shows “234.b” where 234 is build version and b can be d, b or r where d for development, b
for beta and r for release.
The software version is also briefly displayed whenever the unit is turned on. There is nor-
mally also a label on top of the software chip containing the same information.
The unit’s behaviour, features and functions depend completely on the installed software.
Always use the latest software available, especially if you notice that some features are miss-
ing described in any available documentation.
Some new instruments or retrofittable extensions might require a MCU software upgrades. In
this case the unit will display automatically respective help or error codes (HE9, HE14, E16,
E19.n, E32.n, E47.n, E52, E62).
The foot-control and the IMUX also both contain microprocessors. Their software is “embed-
ded” inside their respective CPU’s and cannot therefore be replaced. Since the “main brain” is
the MCB and its microprocessor, there is rarely ever a need for this. However, you can check
their software versions by using service modes n19 and n60 (respectively).
n 2 Show internal unregulated operating voltage (nn.n volt)
This voltage reflects mains voltage magnitude variations. The nominal value is +33VDC and
is allowed to vary ± 15% (28...38V) without affecting the normal operation of the unit.
If one of the MCB electronics fuses (F9 or F10) is blown, the display will only be half of normal
(Ý16.5VDC ± 15%). If the internal voltage is too low or too high, the unit will show respective
error codes (E9 or E10). If the internal voltage rises above 44VDC (a heavy mains surge, too
high mains voltage, wrong voltage jumper position or wrong transformer primary wiring), an
internal protection circuitry will blow fuses F9 and F10, protecting the unit electronics from fail-
ure.
n 3 Show output current of IPS (n.nn ampere)
This is the output current of the instrument power supply (IPS) located on the MCB. This
microprocessor controlled power supply feeds power to micromotors, light-curing bulbs and
scaler units. This built-in ampere meter is intended for checking the current consumption of
the selected instrument. If the current is continuously zero it indicates an open-circuit some-
where between the MCB and the instrument. This mode is also good for checking the no-load
current of micromotors, that is a direct indication of the motor condition.
n 4 Show output voltage of IPS (n.n volt)
This is the output voltage of the instrument power supply (IPS) located on the MCB. This
microprocessor controlled power supply feeds all micromotors, light-curing bulbs and scaler
units with appropriate voltages. The voltage on the display is measured directly at the IPS
output on the MCB, therefore the voltage shown is normally somewhat higher than the instru-
ment receives. However, the voltage drop in the cabling is compensated for so that instru-
ments always receive a proper voltage.
