Control System 30Service Manual – SC2000
System for Flow Rate Adjustment as Function of Speed
Solution ow levels 1, 2 and 3 regulate the ow of solution on the basis of the machine speed so as to keep the
quantity of solution dispensed per square metre of oor treated constant.
The reference ow level is level 3: based on the setting of the corresponding parameter P3, the opening time
of the solenoid valve (and of the detergent pump when tted) is regulated so that the quantity of solution in
centiliters per metre travelled by the machine is constant and equal to the value set in the parameter.
For example, for P3 = 3.0, the machine will dispense 3 centiliters of solution per metre travelled, which equates
(for the standard deck width of 530mm) to 5.7 centiliters per square metre of oor treated.
Levels 1 and 2 are dened via the corresponding parameters P1 and P2 as a % of level 3.
For example, for P1 = 25 and P2 = 50, P1 and P2 are respectively ¼ (25 %) and ½ (50 %) of the reference ow
rate P3.
The default values (the same as in the example above) are summarized in the table, with the corresponding
ow rate values in liters per minute, dependent on machine speed, given as a reference.
SC2000 detergent ow (as a function of speed) (standard setting)
Level 1 Level 2 Level 3
Liters/minute @ 1 km/h 0.2 0.3 0.5
Liters/minute @ 3 km/h 0.4 0.8 1.5
Liters/minute @ 5 km/h 0.6 1.3 2.5
Centiliters per metre cleaned (constant) 0.75 1.5 3
Centiliters per meter
2
cleaned (Ø530 deck) 1.4 2.8 5.7
Level 4 (when enabled) is independent of any parameter and supplies the maximum possible quantity of solu-
tion as it keeps the solenoid valve of the supply system constantly open (with the brush rotating).
