The flow rate is approximately 4 gallons (15 liters) per minute. In order to
compensate for residues on the sensor and aging of the optical system, the
turbidity sensor must be recalibrated regularly. This process is carried out
automatically by the electronic and cannot be modified in any way.
Measurements are carried out at different times during the pre-wash, main
wash and interim rinse stages. For this the top and bottom spray arms must
be supplied with water.
2.16 Spray
Arms
The following speeds apply to all programs except
Pots and Pans
,
China &
Crystal
and
Energy Saver
:
Spray Arm
Speed
Top
40 - 50 rpm
Middle
22 - 30 rpm
Bottom
34 - 42 rpm
Table 050-3:
Spray Arm Speeds
Note:
The programs
Pots and Pans
,
China & Crystal
and
Energy
Saver
are not suitable for checking spray arm speed. These programs are
designed for special applications, such as cleaning heavily soiled loads
(
Pots and Pans
), glassware (
China & Crystal
) or economical
cleaning (
Energy Saver
), and operate with differing water pressure.
The higher or lower water pressure required for these programs is produced
by the MPPW circulation pump; see Section 050-2.11.
2.17
Spray Arm Sensing, Middle and Bottom Spray Arms
(Excella/LaPerla)
Two spray arm sensors are installed on the water intake to monitor the
bottom and middle spray arms. A small magnet is installed on one end of
each of the two spray arms.
The sensor for the middle spray arm is monitored when the circulation pump
is in operation and the slide shutter is in the middle spray arm position.
The sensor for the bottom spray arm is monitored when the circulation pump
is in operation and the slide shutter is in the top and bottom spray arm
position. If the slide shutter position is undefined or if a fault occurs,
monitoring is not carried out.
The time period during which the spray arms are monitored is given by the
electronic. If a fault is detected, it will be indicated but not saved in the fault
memory. The indication will be canceled when the fault is remedied.
The minimum spray arm speed is approximately 5 revolutions per minute.
Therefore, the next pulse should be registered approximately 12 seconds
after the start of the monitoring time.
