Cause : BAMU meas settings comes when error in settings (parameters 191.40…191.43) of BAMU measurement unit. Check the settings of parameters 191.40…191.43.

Check the auxiliary code for details

• 1: Voltage U1 measurement location is not set (check parameter 191.42),
• 2: Either voltage U2 measurement location is not set or voltage U1 measurement location is after U2 (check parameters 191.42 and 191.43),
• 3: Transformer and circuit breaker are either not set or at the same location (check parameters 191.40 and 191.41),
• 4: Voltage U1 measurement location 1 or selection Other is not allowed in this configuration (check parameter 191.42),
• 5: Circuit breaker location B is not allowed in this configuration (check parameter 191.41),
• 6: Voltage U1 measurement is disabled (check parameter 191.01).
