This might be caused by the application of a closing pulse while the circuit breaker is being tripped via the protection relays. Alternatively, it may
SNO 2003-2012
The switch-on monitoring logic triggers relays K1 and K2 which, after response time tA, become self-locking through their own contacts. Simultaneously, the relay contacts of K1 and K2 deactivate the
SNO 1002-2002
Following application of the supply voltage to terminals A1/A2, and the E-Stop switch is not activated, the K1 relay is energized with the RESET switch. The contacts of relay K1 trigger the relays K2 and K3.
Katalog 2 englisch Ausgabe 2000
Simultaneously, the contacts of relays K2/K4 and K3/K5 de-energize relay K1, which goes into its off-position after a drop-out delay time tR1. After this switch-on phase, the three non-delayed enabling
