Note:  You can adjust the maximum vacuum time from 0 to 360 

seconds. See Section 5-11, Menu 1. 

 

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.

 

The 

 LED flashes and the screen displays 

----

 as a four-(4) -pulse blowback cycle occurs. 

 

Note: 

You can adjust number of blowback pulses from 0 to 16 pulses. 
See Section 5-11, Menu 2. 

 

The conveying cycle repeats automatically until the Bin Full 
switch senses that the material receiver (machine hopper) is full. 
The hopper loader stops in Standby mode and the screen displays 

FULL

 until the machine bin level drops and automatic operation 

resumes.
