11. BRUSH DECK removal

12. BRUSH DECK SYSTEM
Brush motor supply voltage controlled by EB1 depending on the load:
24V when consumption is > 9 amps.
20V when consumption is < 9 amps. (adjustable by Superuser key)
Brush motor rpm reduction advantage in light application:
Less water splashing
Less noise
Less stress of the surface due to lower rpm
Lower energy consumption
New shape brush hub with
2 KEYS 5x30

13. BRUSH MOTOR ELECTRICAL INPUT CHECK
Supplier - AMER

Easy replaceable carbon brushes
Apply an ammeter on the cable, Check the motor electrical input is 3 to 4 20 V (without load) 13

14. Brush deck actuator removal

15. Actuator Supplier – SIR 3 position actuator:
Step 0 = retracted - mechanical end of stroke
Step1 = intermediate mm (green LED) electronically adjusted
Step2 = extended mm (red LED) mechanical end of stroke
No adjustment required
Max thrust load: 300 N
Speed: 16mm/Sec
No load current AMPS MAX:1A/24
Full load current AMPS: 3A/24
Stall Amps: 5,5A
IP44

16. SOLUTION SYSTEM SOLENOID VALVE
The solution flow levels 1, 2 and 3 regulate the flow of the cleaning solution according to the speed of the machine keeping constant the amount of solution dispensed per square meter of cleaned floor. The level of reference flow is the level 3: according to the setting of the respective parameter P3, the opening time of the solenoid valve (and the detergent pump if present) is automatically adjusted so that the quantity of solution in centiliters per linear meter path is constant and equal to the value set in parameter.
Level 4: 2,8 L/min full valve open, not controlled by speed.
