prevention regulations as provided by law.
1. Remarks

Foil 7
The Hakomatic B 1100 and the Hakomatic B1050 are equipped with a service indication
in the hourmeter display. Upon switching the key switch ON, a 4-digit code describing
the software version (e.g. 3.018), is displayed for about 3 seconds, followed by another
4-digit code signalling the last error which again is followed by the hourmeter indication.
Upon launch of the Hakomatic B1050, software version has updated to 4.020.
With the software revision 4.026 the Hakomatic B1100 TB 1230 was introduced.
As soon as a malfunction occurs, the red LED signalling a defect lights up and a warning
buzzer sounds. The current error code appears (as 4-digit alpha-numeric code in the
service display) with blinking dots between the digits. When all these criteria are met,
the error is a current one!
There is NO error code, containing a “0”.
Find the error codes listed in a table in chapter 11.
This document uses the following abbreviations:
TSG - low discharge signal sender
SWA - dirty water recycling

Settings on the control electronics/panel which have to be set and checked on
each machine:
In contrast to the Hakomatic B1100, scope of performance of the Hakomatic B1050 is
reduced and does not feature all the options available in the Hakomatic B1100. The
Hakomatic B1050PB (Plate Brush aggregate) has the side scrub unit optionally
available only; the Hakomatic B1050CB (Cylindrical Brush aggregate) has the side
broom unit optionally available, while the pre-sweeper, dirty water recycling and
cleaning agent dosage (99756402) options are available and settable for the
Hakomatic B1100 only. The B1050 PB 1230 doesn´t have any options adjustable via
the control moduls of the machine control system.
The Hakomatic B1100 PB1230 is equipped with the pre-sweep unit generally.

Machine control is effectuated via the following electronics:
Control electronics
Module 1
Module 3 (for pre-sweeper, side broom and side brush, 3rd brush options)
Operator panel
Cleaning agent dosage /SWA operator panel (B1100 only)
Pre sweeper operator panel (B1100 only)
Cleaning agent module (optional, B1100 only)
Auxiliary voltage module (36V/24V transformer)
Voltage to the electronics is supplied by the auxiliary voltage module which transforms
36 Volts to 24 Volts. As the electronics are the same as integrated in the B910 and B
750R machines, the 24V electronics have to be transformed for use in the B 1100 and
B1050 machines. Components such as the motors and pumps, however, are still 36V
components.
The 24V voltage supply must not, even under load, fall below 23V since otherwise, supply
of the modules 1 and 3 would be insufficient and cause a CAN error (4000 error code).
2.2 Brief Description

Foil 12
The control electronics covers all control and monitoring functions in the machine
except for drive control.
Operation of drive controller is independent from the other electronics and only the
release signal and the signal for speed reduction are transmitted via control
electronics to drive controller. Beyond that, a signal is transmitted from drive controller
to control electronics for forward and reverse ride.
Upon occurrence of a defect on the drive controller, an error code is not output since
this controller has its own diagnostic indicator (see chapter 10).
The buttons for scrubbing, suction, scrubbing and suction and the green Hako button
for combined cleaning may be switched arbitrarily such that the selected function is
activated. Pre-sweeper/side broom and /or side brush function can be activated or de-
activated disregarding of the selected cleaning mode, if present in the machine.
The remaining functional buttons (water, brush ground pressure) allow activating or
de-activating the related functions in addition to the cleaning procedure without effect
on the running function.
2.2 Brief Description

Foil 13
The machine is equipped with a seat switch. Activation of this switch is required before
switching key switch on since otherwise sweeping and scrubbing functions (even in
combination) are locked. If the seat switch is not activated, suction can only be
activated for the „Hand suction hose“ option.
A reset of the machine after it was deactivated by the seat contact switch, is realized
by switching off and on again with the key switch.
Constant activation of the seat switch is also required. Leaving the seat while key
switch is ON causes locking of the functions.
The seat contact switch is 3 seconds delayed.
At the Hakomatic B1050 machines the sequence of switching on the machine (key
switch, seat contact switch), has no influence to the ability of function of the machine.
It is equally required to release parking brake to enable cleaning functions and drive
control is released.
To switch on the “TOOL”-function of the B1050 machines, it is necessary to activate
the brake of the machine.
2.2 Brief Description

Foil 14
The suction function is either stopped by the operator via button actuation or
automatically upon the „recovery tank filled up“ signal.
Switching off by operator:
Squeegee is lifted up
Suction motors switch off delayed (15 seconds)
Switching off after tank filled up:
The switch signalling „recovery tank filled up“ opens as soon as the tank is filled
If switch is open for 3 seconds or longer (spill protection) squeegee will be lifted
and the suction motors switch off with a delay of 15 seconds.
2.2.1 Switch Off Suction /
Recovery Tank Filled Up

Foil 15
When turned ON and the seat switch closed, all units of the machine are set to „initial
position“.
This means that the control electronic triggers all units (lifting elements and motors).
Lifting elements will be lifting up as long as they are not switched off by the microswitch controlling the upper limit position and integrated in the lifting element.
This means that the outputs for the lifting elements are powered for approx. 6 sec
every time the machine is switched on. During this time a voltage can be measured at
the outputs for the lifting elements.
Motors are off and the cleaning unit LED indication in the operator panel extinguishes.
The drive controller is transmitted the release signal.
Should the seat switch not be activated, the motors will also be turned off - for safety
reasons - but the lifting elements will not be lifting and the travel drive controller will
not be released either.
The only exception: water suction by hand hose (B1100).
2.2.2 Initial Position/Release,
Lock Functions

Foil 16
Before operation of the pre-sweeper (B1100 & B1100 PB 1230 only), the hood is to be
closed and the dirt hopper correctly inserted. The hood and the dirt hopper are
monitored each by a switch (NC switch) being serially connected. As soon as the
switch opens, the LED in the standard operator panel lights to signal „open hood“ and
the pre-sweeper function is disabled. Since both switches are serially connected, this
LED equally lights if the switch signalling „no dirt hopper inserted“ opens. In case of
faulty function, check the switch and all cable connections and connectors.
Another safety request is effected by the thermal switch of the broom motor. If this
switch opens, the pre-sweeper function will be disabled and an error code appears.
After engaging the parking brake, all cleaning functions will be disabled and the red
LED „brake engaged“ lights. This switch is an NC switch as well and it is thus
required, in case of faulty function, to check the switch, all cable connections and
connectors.
2.2.2 Initial Position/Release,
Lock Functions

Foil 17
Activation of the „Brushes“ function causes lowering of the brush head to the so-called
central position. The lifting element does not attain the lower limit position before
cleaning with increased ground pressure. The brush head lifting element thus has 3
micro-switches integrated, one each for the upper, the central and the lower limit
position.
Extracting the side brush unit is possible only after the brush head had lowered or in
other words: if the central position micro-switch does not switch, the „brush lowering
completed“ signal is missing and the side brush does not swing out. This signal
depends on the central position micro-switch only such that swinging out of side brush
is possible as well for cleaning with increased brush ground pressure. Since on its way
down to the lower limit position the central position micro-switch had been triggered
even if no fault occurred during cleaning with increased ground pressure.

3.4 TSG Error 3211
TSG - Remarks on the error 3211
The controller receives data from the TSG module in serial form and transmission of a telegram
takes one second. The 3211 error occurs when two telegrams with the same contents are not
received within 5 seconds and this equally is the case if there is no transmission at all.
Apart from an actual defect of the TSG the following causes are possible for this error message:
No voltage supplied to the TSG (MK controller: A1:X2.1 + 4)
TSG is in auto test mode: battery DIP switch set to off-off-off or on-off-off (1-2-3) -
from Software revision 4.020 on, this adjustments are used for US-american
batteries
After occurrence of the 3211 error it is also possible to use the LED of the TSG to detect
functioning of data transmission since the TSG bar lights as soon as two telegrams with the same
contents have been successfully transmitted within 5 seconds. In all other cases, the bar does not
light.

8. Water Pump
8.1 Water Amounts
For checking function of the water pump, voltage for each of the stages can be
measured at Module 1 (A5:X2:6+7).
When using a True RMS device, having water in the tank and ensuring that suction
turbine is OFF, the values from the following table shall be obtained:
When using other than the indicated measuring devices, values may vary since
measured voltage is pulsed. Beyond that the value depends on battery voltage.
Here, measurement was done with charged battery presenting three green LED
lighting in the battery indication.
The voltage values in the table are given for the Hakomatic B1100 and B1050PB only.
Beyond that, evaluation of the actually delivered water amount is to be
preferred since voltage values only indicate whether water pump control is
operable or not.

Stage 1: xx V ca. 1,3 l/min ca. 2,7 l/min ca. 1,3 l/min ca. 1,0 l/min
Stage 2: ca. 5,7 V ca. 2,2 l/min ca. 3,3 l/min ca. 2,2 l/min ca. 1,0 l/min

8.2 Standstill Detection For
Water Pump
Automatic standstill detection for water pump:
The electronics offer a possibility for water pump protection if delivery of pump is
blocked.
When the pump takes in water from the tank but cannot deliver it to the brushes,
a pressure builds up downstream the pump. Without protection by the electronics,
the pump would continue delivery against this pressure and could be damaged.
The electronics detects interruption of free delivery of the pump and automatically
switches off the pump for 2 seconds.
After these 2 seconds, pump is briefly switched on with simultaneous measurement
whether delivery then is free or whether water supply to brushes is still blocked.
When delivery of the pump is free, the selected stage remains ON; if counter-pressure
is still present, the pump again is switched OFF for 2 seconds. This procedure is
repeated until fault will be remedied.
