|
|
| 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 |
| 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. | |
