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

•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).

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.

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.
