Parameterization of the ETU input and output
To activate the maintenance mode DAS+ via the circuit breaker's digital ETU input, 2
parameter assignments are necessary:
1. The parameterization of the input to the maintenance mode DAS+ function
2. The parameterization of the signal state. This determines whether the ETU input reacts
to a LOW or HIGH level.
The digital ETU output of the circuit breaker can also be parameterized to "Maintenance
mode DAS+ activated".
Configure the settings in the menu "Device configuration 5.0" using the operating keys
on the display or with the help of the SENTRON powerconfig configuration software.
Parameterization using the operating keys on the display comprises the following steps:
(1)
Device configuration digital ETU input
