Problem

 

Corrective action

 

 

 

Check the Mixer and Dump Setup to see if the mixer is configured

 

 

 

for “Continuous Mixing”. Set it to “Timed Mixing”.

 

 

 

 

 

 

 

Check the value of the mixer timer setting.

 

 

 

 

 

 

 

Check the value of the dump delay timer.

 

 

 

 

 

 

 

Check the mixer motor fuse. This is located in the control panel on

 

 

 

the SSR for the mixer motor. If the unit has two (2) power inlets

 

 

 

with a separate power inlet for the mix motor the overload fuse

 

 

 

will be located in the rear junction box on the blender frame.

 

 

 

 

 

 

 

Check the power source to the blender.

 

 

 

 

 

 

 

Check the load cell in diagnostics under direct scale readout. Place

 

Mixer won’t shut off and runs

 

a calibration weight on the weigh hopper; determine if the weight

 

 

corresponds.

 

continuously.

 

 

 

 

 

 

 

Check the load cells to make sure that a pellet has not jammed

 

 

 

under a load cell.

 

 

 

 

 

 

 

Check the load cell connections to the control panel

 

 

 

Check the power supply voltage and readjust as necessary as

 

 

 

described earlier.

 

 

 

 

 

 

 

Check the memory battery voltage on the CPU board. If the

 

 

 

battery is dead, the blender “forgets” settings when the power is

 

 

 

off. Replace it with a new battery. Order a spare CPU board; send

 

 

 

the replaced one back to the factory to have a new battery holder

 

 

 

and battery installed. If this is done in the field, the controller

 

 

 

warranty will be voided.

 

 

 

Go to the Manual Control Page and check to see if “Hop Low”

 

 

 

equals “1”. If it does, then adjust the low-level prox until the value

 

Out of Material Alarm is

 

reads “0”.

 

 

 

 

 

Ensure that the material hopper is properly vented. If the vacuum

 

displayed, but there is material

 

 

 

receiver is leaky, then this will cause the problem. To test this, fill

 

in the hopper.

 

 

 

up the hopper and turn the loader off to prevent leaking.

 

 

 

 

 

 

If this isn’t the problem, then increase the “Out of Material Retry

 

 

 

Limit” found under Feed Algorithm Options (see manual).

 

 

 

 

 

I’m not getting Out of Material

 

Check the Alarm Flags & Feeder Setup to see if the feeder is

 

Alarms

 

configured to give you an alarm.

 

 

 

 

 

 

 

Clean out the hopper and retest. If this doesn’t fix the problem,

 

Calibration Weight Exceeded

 

then perform a scale calibration. Also, check to sure that the

 

 

Dump Time is not set extremely low. If all else fails, check the

 

 

 

value set for the Max Empty Weight. This might need to be

 

 

 

increased.

 

 

 

 

 

The feeder calibration values

 

First, check that the displayed actual dispensed weight is accurate.

 

 

If this is OK, then check to see if the hopper is properly vented.

 

are moving too much.

 

 

 

To do this, fill hopper and turn off the loader and retest.
