9. Trouble shootingProblem : The balance does not come into specification or a Maximum deviation alarm occurred.Possible causes:1. Check if all cables are connected correctly.2. Check if the transport protection is removed from the load cell safety bolt.3. Check if the hopper assembly is fixed tightly to the weighing platform and that the neckpiece is fixedtightly to the production machine.4. Check if the dosing cylinder is tightly fixed to the motor shaft.5. Excessive build up of material on the dosing cylinder may have impact on proper dosing.To avoid this, be sure that the seals and dosing cylinder are clean.6. Check if there is no tension on the cables connected to the weighing platform.7. Use the weight check function with the reference weight to determine the correct function of theweighing system.8. If the weight check gives the correct result, check if the material flow into the cylinder has beenblocked.9. Another cause may be an obstruction to the weighing system. Check if there is at least ≈ 1mm spacebetween all the pointed screws and the load cell frame or platform and that there is no material ordirt blocking the movement.10. In case of a water cooled neckpiece, check if there is material build up around the dosing cylinderand the water cooled pipe that can obstruct the free movement of the weighing system.11. Check if the input signal is stable.12. If none of the above causes the problem, recalibrate the system and try the weight check again.Problem: The balance does come into specification but seems to be slow.Possible causes:1. Extreme vibrations and shocks to the system.2. Extreme low Setpoint. See Chapter 8: SYSTEM PERFORMANCE3. Check in case of use of an automatic hopper loader if the hoses are connected in the right way.Problem : The input/start-signal is connected but the unit does not recognize this start signal.Possible causes:1. Check if the correct wires are connected for potential free contact, potential contact or tacho. Alsocheck if the + and – side are connected correctly.[See chapter 6.5 , 7.4 and the Wiring diagram in Appendix B.]2. The first delivered series controllers has a different main board than the present ones. The changesin the wiring diagram for main boards with the code MVC000BA02 (version 2) regarding to theMVC000BA03 (version 3) can be seen in appendix B.The version code is printed on the main board.3. Automatic fuse is activated, this can for example happen when there was a short-circuit at the inputconnection. To deactivate the automatic fuse the controller needs to be switched OFF for a whileand ON again, but first check and repair the short-circuit.Problem: The hopper weight is not stable.Possible causes:1. Check if the weighing signal is not influenced by external circumstances, for example that theloadcell cable passes near to electromagnetic fields or electro motors.2. Extreme vibrations and shocks to the system.3. Check if there is no obstruction to the weighing frame.4. Check in case of use of an automatic hopper loader if the hoses are connected in the right way.39MC-Balance manual
