2.8.1 Information on the display

Diagram Description: MID displays

The diagram shows examples of different MID display states:

• Normal operation: Displays total energy (kWh) and firmware version/checksum.
• Relevant error, Counter still valid: Indicates an error but the counter value is still valid.
• Relevant error, Counter not valid: Indicates an error where the counter value is not valid.
• Normal operation, New log entry: Indicates normal operation with a new log entry.

If the device is in the sleep state, no information is displayed. In the sleep state, the system prohibits the transmission of energy (for details, see "3.2 Operational readiness").

Short description of the displays

• Line 1: Total sum of the energy registered by the device in [kWh] for all charging sessions to date.
• Line 2:
  • 01.00.00 AB12 *: Firmware version, Checksum, New log entry present.
  • Error: Relevant error on the KC-MS10, the module is out of operation. Operation can only be restored by replacing the charging station or the KC-MS10 module. If an energy meter reading is displayed, this count value is correct despite the error.

3.1 Non-return device

The measurement device has an integrated non-return device. Energy is only recorded if it flows from the supply terminals to the output terminals (charging cable).

3.2 Operational readiness

The meter function is active in every operating mode in which energy is flowing through the device. If the KC-MS10 module is in the sleep state, the main relay is open, which prevents the transmission of energy.

3.3 Measurement principle

The transmitted energy is measured in all active phases.

Diagram Description: Measurement scheme

The diagram illustrates the measurement principle of the KC-MS10 module. It shows the power supply, measurement points, and output terminals. The components are labeled:

• 1: Power supply to the supply terminals
• 2: Power tap for internal supply: Before the active power meter
• 3: Power measurement/active power meter
• 4: Switching element
• 5: Outlet for charging cable

The switching element (4) refers to the additional function of the KC-MS10 and is not part of the meter function.

4.1 Checking the compliant state of the device

To get a valid reading on the energy meter value, the following points must be checked:

• The integrity of the energy meter and its associated components must be checked.
• The device must be within the calibration period. The information can be found on the type plate of the device and is marked with the letter "M", followed by the last two digits of the calibration year.
• Use of a suitable device type.
• Correct function and readability of the display.
• Display of the correct firmware version according to the type examination certificate on the display.
• All calibration seals must be present and undamaged.
• Correct installation of the device and energy meter in compliance with national and regional regulations.
• Operation according to the operating conditions.

4.2 Permitted MID software version

A device with an installed KC-MS10 measurement device includes conformity-relevant and non-relevant software parts:

Firmware assessed for conformity

• Firmware version: 01.02.02
• Checksum: 89A1

4.3 Periodic checking

To minimize damage due to failures, it is recommended that you read the meter and thus check the compliant state of the device in reasonable intervals.

If the device is in a non-compliant state during the check, it must be assumed that the meter reading is invalid back to the last valid reading.

4.4 Correctly reading the energy meter

All KC-MS10 variants with a calibrated energy meter have an LCD display. It enables visualization of all relevant information, including that of the energy meter.

Outside of the sleep state, the relevant information is displayed permanently. For improved readability, the backlighting of the display is activated in case of relevant charge events.

Relevant events are:

• Start of a charging session
• Plugging in the charging cable
• End of the charging session
• Unplugging the charging cable

4.5 Displays of calibratable energy meters

4.6 Firmware update

KeContact P40 supports updates to the legally relevant firmware. An update is triggered through the connected gateway (application module). Only firmware versions approved by the notified authority are installed on the device.

Updates to the relevant firmware may require additional approval by the local authorities.

5.1 Calibration mode

If you set KC-MS10 to calibration mode, the functions required for the calibration are enabled:

• Main relay is closed.
• Pulse LED is active and flashes at 10000 pulse/kWh.
• Additional functions¹⁾ of KC-MS10 are deactivated.

In calibration mode, neither the mode of operation nor the measurement accuracy of the active power meter change. The energy transmitted in calibration mode is therefore added to the total energy meter.

¹⁾ KC-MS10 is capable of executing charging sessions in accordance with IEC 61851. In calibration mode, the Control Pilot voltage is set so that the device cannot execute any charging processes in accordance with IEC 61851. KC-MS10 has integrated functions of an RCD and RDC device. In this mode, these functions are disabled. This prevents the RCD function of the device from being triggered unintentionally during the test. Monitoring of the contactor function (weld detection and read-back contact) is deactivated.

5.2 Activating calibration mode

For calibration mode, a specific test firmware is required as a software update; this can be provided by the manufacturer on request. To activate calibration mode, proceed as follows:

• Install the specific test firmware using the normal software update process.

Calibration mode is activated.

5.3 Optical test output (pulse LED)

Diagram Description: Optical test output

The diagram shows the KC-MS10 module with the optical test output (pulse LED) labeled as '1'.

The optical test output is a pulse LED located behind the type plate, which is visible from the outside through a corresponding opening.

5.4 Schematic measurement setup

Diagram Description: Schematic measurement setup

The diagram illustrates the schematic measurement setup for calibration. It shows the connections between the calibration test system and the energy meter:

• 1: Calibration test system
• 2: Supply terminals
• 3: Output terminals (charging cable)
• 4: Optical test output (pulse LED)
• a: Connection lines (source including voltage measurement)
• b: Connection lines (sink)
• c: Evaluation unit for pulse LED

The calibration test system is connected to the energy meter. The voltage is tapped according to the evaluation point at the supply connection on the supply terminals. The test probes are connected to the output terminals on the output side. The optical test output must face the counterpart of the calibration test system.
