Recommendations for input and output signals
Recommendations for Input signals
Please see the default factory configuration.
BLOCK: The input will block the operation of the Overexcitation protection
OEXPVPH (24), for example, the block input can be used to block the operation for a
limited time during special service conditions.
RESET: OEXPVPH (24) has a thermal memory, which can take a long time to reset.
Activation of the RESET input will reset the function instantaneously.
Recommendations for Output signals
Please see the default factory configuration for examples of configuration.
ERROR: The output indicates a measuring error. The reason, for example, can be
configuration problems where analogue signals are missing.
