Starting behavior of the safety option

DANGER

After a error, the safety option automatically restarts if the supply voltage is switched on, if the standby mode is completed, or if certain inverter error are acknowledged.

Severe or fatal injuries.

• The Error status after startup parameter must be parameterized to "start inhibit". This way, the automatic restart of the safety option is prevented in the cases mentioned above.

In the "Basic settings" of the "Assist CS.." parameterization tool, the starting behavior of the safety option can be defined using the Error status after startup parameter. The following parameter settings are possible:

• "Start inhibit" parameter setting
• The safety option always starts with start inhibit after the supply voltage is switched on. This parameterization is provided for independent operation.
• "No start inhibit" parameter setting
• The safety option starts immediately. Note that errors must be acknowledged by switching the supply voltage off and on again or by quitting standby mode. This means that a error pending prior to switching off the supply voltage or during standby mode is acknowledged and the safety option starts up. This parameterization is designated for fieldbus operation where the higher-level controller, if necessary, takes over interlocking in case of a error.

Start inhibit is deactivated if one of the following conditions is met:

• An acknowledgment has taken place
• Muting is activated
