Description

Note

Keys are included

Functional description

In combination with a control system, the Euchner Control Box allows dangerous machine movements to be performed as long as all valid unique, transponder-coded keys (CKS keys) are inserted. If at least one CKS key is removed during operation, the two safety contacts are switched off and a stop command is triggered. The safety contacts remain switched off when the CKS key is removed. The installation cannot be restarted.

Function as lockout bar

When the CKS keys are removed from an ECB device up to two persons can access the hazardous area for servicing. As long as the operator carries the CKS key with him, there is no hazard for the operator due to unexpected machine start-up or being locked into the machine unintentionally. The ECB therefore performs the function of a safe lockout bar. The system can fulfill its safety function only if the users always carry their CKS keys with them when accessing the machine.

Function as trapped key system

When the CKS key is removed, the operator can enter the hazardous area safely and can use the same CKS key to start local machine functions via another ECB device.

Safety characteristics according to EN ISO 13849-1
