1. REMARKS
•Caution:
•Before working at the machine make sure that no voltage
applies (disconnect battery plug); except for cases of
current and voltage measurement.
•When replacing the stripe fuses only loosen the screws.
Do not remove them completely to avoid short-circuit
hazard.
Place the new stripe fuses completely i.e. evenly under
the screws.
•Measure starting and operating voltage after any repair
action to detect any eventual defect.
•The applicable safety and accident prevention regulations
as imposed by law have to be respected when working at
the machine.

For Internal Office Use Only
2. GENERAL
•The ADMIRAL 30/32 uses a service display integrated in the
hourmeter display. When turning the key switch ON, a 4-digit
display will appear for about 3 seconds, describing the software
version (e.g. 3.017), then another 4-digit display may appear which
repeats the last error, followed by the hourmeter display.
•In case of malfunction during operation, a red error LED alights
and a buzzer sounds. The actual error code (4-digit number in the
service display) with flashing dots between the numbers will
appear in the service display. Only if these criteria are fulfilled the
error is actual.
•The versions 7090.10/20 of the ADMIRAL 30/32 machines are
equipped with an integrated charger unit; the versions 7090.30/40
need an external charger unit. The versions 7090.10/30 work with
plate brushes, the versions 7090.20/40 work with cylinder brushes.
•The separate instruction manual of the integrated charger unit is
enclosed in the machine. The working and error codes of the
charger are enclosed in the charger manual.

For Internal Office Use Only
2.1 SETTINGS
The following settings on the control unit (A1)/control panel of each
machine must be defined and checked:
• machine type
• LDS (low discharge signal sender)
• options
• delete last error display after elimination
• program variants with a given drive rheostat position
Settings via control panel which may be defined by the customer:
• display of the last (eliminated) error when turning the machine ON
• water stage selection when start cleaning
Settings on power electronic module:
DIP-switch for electronic circuit breakers

For Internal Office Use Only
2.2 BRIEF DESCRIPTION
The following electronic modules control the machine:
•control unit (A1)
•power electronic (A2), referred to as ”module 1” in the diagrams
•drive control unit (A4)
•control panel (A3)
The control unit (A1) ensures all control and monitoring functions in
the machine except for the drive control unit.
No particular error code is displayed when an error occurs at the
drive control unit since it is equipped with an independent diagnosis
display (flashing LED at the drive control unit) (see chapter 9).
The keys for scrubbing, vacuuming and the green ADMIRAL key for
combined cleaning can be used autonomously, only the selected
function being active.

For Internal Office Use Only
2.2.1 VACUUMING OFF/ soiled water
tank full
The vacuuming function is turned OFF either by operator’s key action
or automatically when the signal “Soiled water tank full” applies.
Operator turns vacuuming OFF:
•squeegee is lifted
•suction motor turned OFF with a delay of 15 seconds
Turned OFF when tank full:
•the “soiled water tank full” switch opens as soon as the tank is filled
•If the switch opens 3 seconds or longer (spill protection) the squeegee is
lifted and the suction motor turned off with a delay of 15 seconds.

For Internal Office Use Only
2.2 INITIAL POSITION OF THE MACHINE
•After turning ON the machine, all components are set to “initial position”
after the seat contact switch has closed.
•The lifting elements will lift if they have not been turned OFF in top final
position by the micro switch integrated in the lifting element.
•The motors are turned OFF and the LEDs on the control panel for cleaning
elements extinguish.
•The seat contact switch is connected to the control unit A1 at
A1:X7:11+12.
•The A1 control unit’s reaction to activation (opening) of the seat contact
switch is delayed by 2 seconds i.e. if, during operation, the contact is
opened for more than 2 seconds, the motors stop and brush head and the
squeegee is lifted.
•If the switch is closed again within this delay, operation is not
interrupted.
•When the machine is switched ON without the seat switch being closed or
when the switch is opened for more than 2 seconds all functions (driving
and cleaning) are now inhibited.

3.1 CHECK AND SET MACHINE TYPE
1. Setting the correct machine type is absolutely necessary. To do so use
the
DIP-switch A on the control unit (A1).
2. For the B750R type the first and the last bar have to be positioned in
the top line
and the second and third bar in the bottom line. This setting results in
the
displayed cipher 9.
3. If the display does not correspond with these parameters, correct the
DIP-switch
combination.
B750R 1: ON (= bars in top line)
2: OFF (= bars in bottom line)
3: OFF (= bars in bottom line)
4: ON (= bars in top line)

For Internal Office Use Only
3.2 CHECK AND SET OPTIONS
1. The setting of all options on the DIP-Switch B of the control unit (A1) is
absolutely
necessary.
2. The DIP-switches are assigned as follows:
1 - 3: unassigned, i.e. “OFF”
4: OFF
5: OFF
6: plate brush or cylinder brush unit
(ON = cylinder brush; OFF = plate brush)
7 - 8: unassigned, i.e. “OFF”
3. The only option switch used in the B750R is switch S6. It is used to toggle
between
plate brush and cylinder brush.
These machines are not provided for more options and all switches have to
be
set to OFF.
