- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Frequent PC / network disconnections
MediumSymptoms: C8000 drops off BatteryLab repeatedly, Data Monitor shows no communication.
Root cause: Duplicate TCP/IP address on the network, or a marginal Ethernet cable / port.
Channel driver / power-stage failure
HighSymptoms: One channel fails tests, no charge or discharge current, over-temperature on that channel.
Root cause: Blown output device or driver on that digital channel, or a cooling-fan fault.
Calibration data lost or corrupt
HighSymptoms: Test results inaccurate, calibration warning, factory calibration not found after a system update.
Root cause: Calibration database not backed up before an update, or storage corruption.
External load-bank / high-power discharge fault
MediumSymptoms: Cannot reach rated discharge wattage, load bank not recognised, thermal shutdown.
Root cause: Load-bank connection, fan, or element failure.
Battery-adapter / channel connector wear
LowSymptoms: Intermittent "no battery" or contact-resistance errors on a channel.
Root cause: Worn or dirty adapter contacts and channel terminals.

Error Codes
Extracted directly from this unit's own service manual.
10No battery is inserted, or the inserted battery is not detected.
Check and clean all contacts.
12Battery temperature is too cold when inserted. The battery is trickle charged until temperature rises above minimum. (Only for NiCad / NiMH).
Allow the battery to warm up.
13Battery temperature is too hot when inserted. The battery automatically starts processing when temperature drops 5°C below maximum value.
Allow the battery to cool or use the tester in a cooler room.
14Battery has overheated during charge. Channel goes to Resting 00:00 (code 19) until the battery cools.
Reduce the Charge rate in the C-code.
15Current battery-service program is complete.
16The program has produced an error. The Next statement is not processed. The program has been terminated.
See the detailed display for the exact nature of battery failure.
17Battery was removed when the program completed. This message appears briefly when the battery is removed.
If message persists, press ESC.
188An abort command has been issued. Program terminated. The user issued an abort command.
19Channel is in a rest period, as specified in the program. The program will proceed to the next step when resting period is complete.
20The C8000 detects a battery in an adapter. If message persists, press ESC.
Press ESC.
21PROGRAM IS PAUSED (CUSTOM PROGRAM FUNCTION ONLY).
255A system operation, such as a firmware upgrade, is being performed.
26User suspended the test. Resume or wait for the condition that caused the "suspend" mode to be resolved.
If this message persists, abort the test. If this condition cannot be resolved, contact Cadex for support.
112Cells are reaching full charge at different times so the negative slope is not well defined. The program proceeds to the next cycle.
Wait until processing is complete.
113Battery was fully charged before full-charge conditions were met. For SLA and Li batteries only. The end-of-charge setting in the C- code may have to be increased.
Battery may be old and operating time less than manufacturer's specifications.
116Final capacity of the battery is below the target capacity. Attempts to improve battery capacity did not succeed in bringing capacity above target.
Battery is old and has less operating time than manufacturer's specification.
120Battery voltage is too high. Discard the battery.
121Reverse voltage detected on insertion. Battery may be connected backwards in the adapter. Ensure that battery leads are firmly connected to the battery.
Ensure that battery leads are firmly connected to the battery.
122Battery voltage is lower than (the voltage remains low).
Ensure battery leads are firmly connected to the battery. Battery may be shorted.
123Battery voltage remains low after approximately one minute into the charge cycle.
See BATTERY SHORTED, Code 122.
124Battery voltage remains low after approximately ten minutes into the charge cycle.
See BATTERY SHORTED, Code 122.
128Battery voltage is too high. Processing has ended. Battery may be a high capacity type battery.
Check that correct contacts are used. Battery may be in poor condition.
142Battery capacity has exceeded 250% of the rated capacity.
144Charge time has exceeded the expected value for the battery. Tester may not have detected the end of charge conditions.
159Battery temperature has exceeded its maximum setting after service has ended and battery was on trickle charge. The trickle charge stops.
Lower the room temperature. Verify that the C-Code is correct for the battery. Battery may be in poor condition.
162The tester cannot discharge the battery.
See BAD FUSES OR DRIVER, Code 160.
164Tester cannot provide the requested charge current
See BAD FUSES OR DRIVER, Code 160.
207Service on all channels is temporarily suspended due to high temperature inside the tester. Service will resume in a few minutes, after the board has cooled down. If it reoccurs continuously, move the tester to a cooler room.
32Power resumed or the battery is re-inserted into the adapter.
33The time programmed in a custom program setup has completed.
The program g
231LOAD CAPTURE DEVICE IS DETECTING A REVERSE CURRENT FLOW
232LOAD CAPTURE UNIT IS BEING CALIBRATED
233TEMPERATURE IS OUT-OF-MEASURABLE RANGE

236NO CHARGE ALLOWED ON PRIMARY CELLS
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: C8000 keeps disconnecting from the PC
- From the C8000 menu open Data Monitor and confirm whether it is communicating at all.
- Have the network admin check for a duplicated IP address on the subnet and ping the C8000.
- At the C8000 Ethernet port confirm a solid link light and a blinking activity light.
- Swap the network cable and try a different switch port.
- Assign a static IP outside the DHCP range if duplication recurs.
Symptom: One test channel fails or has no output
- Move the same battery/test to another channel to confirm the fault follows the channel.
- Check the cooling fans run and airflow is clear; a thermal fault can disable a channel.
- Inspect and clean the channel and adapter contacts.
- Back up calibration data, then replace the channel power module.
- Restore calibration and re-verify against a reference battery.
