6.3 Safe energy monitoring

The IMD monitors continuously the SE voltage. Using CAN/CANopen or the IMD Manager, it is
possible to read the actual SE voltage. IMD 122 C has an extra input for measurement of the mid-
point voltage. A wrong mid-point voltage, SE voltage or both, is an indication that a battery or ultra-
capacitor module are defective). No warning or configuration are associated with this function, and the
IMD does not take any action or evaluation. Evaluating the value and taking actions is done by
external controller.
If the SE voltage is below SE Vlow parameter value, a "POWERVOLTAGE sources < min" warning is
generated, it is not possible to disconnect mains either from the IMD Manager or CAN/CANopen.
NOTE If no SE source is connected, the measured values of SE+ and SEM are random (0 to DC-link
voltage) due to the protection circuit or the charger. However, the charger will detect it and
report an error.
