Troubleshooting
1. Check for error codes on the display.
= Bad load cell connection or damaged load cell. Verify load cells are connected
to the control unit per the wiring diagram. Inspect cables for cuts or broken wires.
= Negative load cell flow. Verify load cell connections to the control unit are per
the wiring diagram.
= Positive load cell flow. Load cells are too small for the application and must be
replaced with proper units.
= Polarity error. Verify load cell connections to the control unit are per the wir-
ing diagram. Reprogram the control.
= MB-D display short. Locate the short. Disconnect MB-D display, turn off the
control, then reconnect the MB-D display.
= Loss of data in memory. Reprogram the control.
2. Verify that proper voltage is being supplied to the control unit.
3. Check all connections to the control unit.
4. Check the fuse: Disconnect power to the control unit. Open the unit by removing the five
(5) screws that hold the cover. Remove fuse from black fuse holder next to controller
transformer and replace with new fuse if necessary.
