5.0 BCi Integrator Troubleshooting Tips
The following table lists general troubleshooting tips for various hardware and software error conditions
regarding the BCI in-motion belt scale.
Symptom Remedy
integrator does not power up Possible blown fuse or bad power supply. Check fuses and replace if necessary. If fuses
are good, check all voltages on CPU board. Power supply should output both +6V and
–6V levels to the CPU board. If power supply appears bad, check the small glass fuse
(2.5A, 5x20mm) on the power supply board.

Power supply overloaded. Check for shorts in A/D card regulators or in the DC-to-DC
converter of any installed analog output or pulse input cards.
"Blue screen" Check LCD contrast pot (under interface board access cover; possible corrupt core
software; reset or reload software.
Tare storage is corrupt error
messages at startup Possible dead battery. Perform configuration reset then check for low battery warning
on display. If battery is low, replace battery, perform another configuration reset, then
reload files.
Divide by zero error message at
startup User program error.
Dashes in weight display Overrange or underrange scale condition. Check scale. For out-of-range conditions in
total scale display, check all scale inputs for positive weight values.
Display reads 0.000000 Scale not updating. Check for bad option card hanging the bus.
Cannot enter setup mode Possible bad switch. Test switch; replace interface board if necessary.
Serial port not responding Possible configuration error. For command input, ensure port INPUT parameter is set to
CMD.
A/D scale out of range Check source scale for proper mechanical operation. Check load cell and cable
connection. Possible bad load cell: check integrator operation with load cell simulator.
Locked — Scale in use Scale is assigned as an input to a total scale or is the source for a serial scale, analog
output, or setpoint. If not correct, deconfigure this scale assignment and reconfigure as
required.
Option x Error Field bus card (Profibus, DeviceNet, or Remote I/O) in slot x failed to initialize.
Option card failure Possible defective card or slot. Disconnect power, install card in different slot, then apply
power again.
