“CL” on the keypad is a warning message indicating that the motor is drawing more amps than the current limit setting entered into the VFD. This warning message may be displayed for multiple reasons, all of which are listed below, along with possible solutions:
1. Aggressive use of product feeder
The product feeder should be used to gently feed produce through the grinder. If an operator is applying too much force you will notice the CL warning. Most probable reason for applying too much force is a dull or incorrect grinder disc. Restart grinder after inspecting grinder disc, and be careful not to apply too much force when feeding the produce into the grinder.
Extremely aggressive use of product feeder may cause the the stub shaft to move down on the motor shaft. This causes the shaft seal located beneath the grinder backing disc to become squashed. A squashed shaft seal will result in a slight burning smell accompanied with the CL warning. See stub shaft alignment article to rectify.
2. Incorrect speed setting
There is a direct relationship between speed and horsepower when operating the grinder. As you increase speed you increase the horsepower. If you experience a “CL” warning when operating at slower speeds(below 45hz), increase the speed to above 45hz and continue grinding.
3. Product build up
While processing certain products, A “CL” warning will be an indicator of built up product inside the EG-260 feed hopper. This can happen after long production runs. To address this, simply remove the hopper, clean out built up product and reattach the hopper.
4. Dull or incorrect grinder disc
The grinder discs are considered a consumable part and after extended use they will start to dull. As a grinder disc dulls it becomes more susceptible to clogging and allowing product to build up. It is recommended that a replacement grinder disc is on hand at all times. Using an incorrect grinder disc can also cause a CL warning. Always match the grinder disc to the product you are grinding.
