VendorID2 :RTM Errors
RTM errors are generated by the charger when an error occurs and the charging is stopped.
They can be found as “RTM err code” in the Diagnostics tab of the web client.
This error code is sent when the AC RCD protection is
triggered. RCD or “Residual Current Device” is a fault
current protection hardware used in chargers to protect
the user from current leakage.
This error code is sent when one of the following occurs:
The line terminal and the N terminal are swapped
There is more than 70VAC between the N line and the
earth
There is a missing earth or bad earth connection
This error code is sent when the car decides to import
higher current than charge point offers. If the current
demand is 10% above the set current limit and lasts more
than 6 seconds, the fault is generated. Note that the
threshold is 10% of the present current limit, not the
absolute maximum.
This fault can be cleared by power cycling the system, by
unplugging the charging cable or via the web client
Output
RELAYS state
error
This fault can be cleared by system power cycle, by the
charger’s web client
This error code is sent when the DC RCD protection is
triggered.
Note that when the DC RCD is triggered the error code
0x0001 is also sent!
EVSE_FAULT_
ACT_LOCK_FAUL
T
Actuator lock
malfunction
On models with a safety electromechanical lock, the
charger monitors the lock position. A fault occurs if the
actuator fails to lock its pin when a command is sent
EVSE_FAULT_AC
T_UNLOCK_FAUL
T
Actuator
unlock
malfunction
On models with a safety electromechanical lock, the
charger monitors the lock position. A fault occurs if the
actuator fails to unlock its pin when a command is sent
EVSE_FAULT_
DIODE_UNPRESE
NT
EV diode
error - diode
in EV not
detected
EVs have a diode on the CP line as part of the charging
standard. This error code is sent if the charger cannot
detect the diode in the EV. The fault is in a problematic
EV diode and is cleared by removing the faulty device
Proximity
pilot not
detected
This error code is sent when a charging cable is plugged
in and an attempt is made to start a session, but the
charging station cannot read the PP resistor of the
charging cable. The charging session will not start.
This error code is sent when the temperature of the
charging station reaches more than 79 degrees. At this
point the charging station will stop charging at all. This
fault is cleared when the charging station is power cycled
or through the web client.
This error code is sent when the power supply voltage
rises by more than 10% of nominal
