1. Remarks

•Caution:

•Before working at the machine make sure that the batteries are disconnected

(disconnect battery plug); except for cases of current and voltage measurements.

•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 guide lines should be followed

2. General

•The Minuteman E Ride 30 uses a service display integrated in the hour meter

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 hour meter 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

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

Di C t lU it(A4)

•

(A4)

•Control Panel (A3)

•The control unit (A1) ensures all control and monitoring functions in the machine

except for the drive control unit

•There isn’t any error code is displayed on the dash board display, when an error

occurs at the drive control unit since it is equipped with it’s own diagnosis display

(flashing LED at the drive control unit) (see chapter 9).

(see

chapter

•The keys for scrubbing, vacuuming and the green Minuteman key for combined

cleaning can be used autonomously, only the selected function being active.

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 “Dirty (Recovery) water tank is full” applies.

•Operator turns vacuuming OFF:

•Turned OFF when 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.

2.2.2 Initial Position of 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.

2.2.2 Initial Position of Machine

•Test the seat contact switch, its wiring and the module’s input by means of the

dia

as detected by the module.

•The drive control unit is equipped with an individual diagnosis and self test function.
