Actuator Control
증상 : Actuator does not work properly
원인 :
- Different operation characteristics of the actuator from each manufacturer.
- Incorrect pin connection
해결책 :
- Check the CAN data of EVCC in terms of setting of actuators types.
- 0x1EBCC001.1.0 (01: Phoenix 12V, 02: Phoenix 24V, 03: REMA, 04: Amphenol, 05: Hela)
- The 3rd makers’ actuator other than stated above, please check with Gridwiz team. - Check the status of the connection between actuator and connector pin.
- ACTUR_N (Pin 14), ACTUR_P (Pin 7)
<3-Wire-Actuator>

CAN Communication
증상 : CAN Communication Problems
원인 :
- Incorrect CAN wiring
- Mismatching of CAN ID setting
- CAN H/W faulty interface
해결책 :
- Check the status of connection between CAN pins and EVCC.
(CAN_H -> Pin 10, CAN_L -> Pin 18)
- EVCC does not have a termination resistor on its CAN bus. 120ohm termination resistor needs to be placed at both ends of the CAN bus.
Pin # Pin Name 10 CAN_H 18 CAN_L
- Check the accordance of the CAN ID of the request upon ordering and the ID on EVCC’s H/W.
- EVCC’s default CAN baud rate setting is 500kbps. - Check 0x1EBCC001.7.0 (evccHeartbeat) via Can analysing tool (e.g. PCAN-Explorer, CANalyzer)
- If it works properly, the value is continuously changing from 0 to 255.
Controlling CP Level
증상 : The CP voltage level of vehicle is not changed from 12V to 9V.
원인 :
- Incorrect initial setting of EVCC.
해결책 :
- Check the subject of CP level switching whether it is changed by EVCC or EV System by its booting log information.
- S2 switch control by EVCC
- S2 switch control by EVS (EV System)
General Charging Failure with EVSE
증상 : Charging failure with EVSE
원인 :
- Incorrect EVCC controlling
- Faulty EVSE status
해결책 :
- There are huge number of causes of charging failure with EVSE. Extract the serial(RS-232) log starting from the beginning of the charging to the end and send the charging log to Gridwiz for analysing.
- Gridwiz team will reach back to sender with accurate analysis of the log sent.
RS-232 Configuration
증상 : RS-232 Log is not checkable
원인 :
- Incorrect RS-232 wiring
- RS-232 H/W faulty interface
해결책 :
- Check the connection of RS-232 whether it is wired to D-sub 9pin. (female)
- Install the serial terminal program (e.g. Tera term), set up the details such as serial port, and baud rate and check whether the logs are able to be extracted.
EVCC’s default serial baud rate setting is 115200.
