Problem Possible 
cause 
Solution 
The controller panel is not 
plugged in. 
Plug in the controller panel. 
The external disconnect 
(recommended) in the dedicated 
circuit is open (off). 
Close the switch (on). 
Fuse/circuit breaker in the power 
drop is blown/tripped. 
Replace/reset. 
The controller panel doesn’t light 
up at all. 
Broken controller power switch. 
Replace. 
The motor overload has tripped. 
Reset the overload and check 
the motor for the proper amp 
draw on tag. 
Main fuse in power drop or 
optional fused disconnect has 
blown. 
Replace the fuse. 
A pump package doesn’t run, 
even though it is on line and its 
indicator is lit. 
Motor contact is faulty. 
Repair or replace as required. 
The bin below it is full if its 
amber indicator light is off. 
Normal operation. When the 
level drops, material conveys to 
the hopper. 
The hopper is off line. 
Using the controller, place the 
hopper on line. 
The convey time for the hopper 
is set to zero. 
Using the controller, enter a 
reasonable convey time. 
The field-installed station bypass 
switch is simulating a Bin Full 
condition. 
Normal operation. Set the switch 
so the hopper is back in the 
loading sequence. 
A vacuum hopper is being 
bypassed in the loading cycle. 
The field-installed station bypass 
switch is bad or mis-wired. 
Repair, replace, or rewire. 
Conveying times are too long 
(Time Fill mode only). 
Time the hopper(s) during 
loading, and set conveying times 
to a few seconds less. 
Vacuum hoppers are over-filling.  Maximum conveying times are 
too long and the PCB does not 
recognize the Hopper Full 
proximity switch(es). 
Check proximity sensors for 
proper operation and proper 
wiring to the PCB. Repair as 
needed. Reset the conveying 
times to a reasonable value, and 
adjust as needed.
