The MATERIAL “A” and MATERIAL “B” LEDs alternate on
and off as set in Steps 4 to 6 above. This indicates the
proportioning valve cycle.
Example: If the percent of Material B was set at 50% in Step 4, the
MATERIAL “A” and MATERIAL “B” LEDs alternate ON for
ten second periods; this equals 50% of the factory-default thirty
(30) -second proportioning cycle.
Note: The proportioning SPV total cycle time is adjustable; see Section
5-11, Menu 4 for more information. This time is not the same as
total vacuum time. To see the relationship between these two time
parameters, see Figure 10, Proportioning Cycle.
When the proximity sensor trips or sixty (60) seconds elapses, the
vacuum motor shuts off for three (3) seconds to relieve vacuum in
the hopper and to allow the material to dump.
