Automatic Speed Undershot; Setup Speed Exceeded; Setup Speed Undershot; Standstill Speed Exceeded - Siemens 3TK2810-1 System Manual

7.4.7.2

Automatic speed undershot

If the parameterized minimum automatic speed is undershot, the device switches
immediately to the safe state. Contacts 23/24 are opened and when the lower parameterized
standstill speed limit is violated, contacts 13/14 are closed. The corresponding signaling
outputs are switched.
7.4.7.3

Setup speed exceeded

If the parameterized maximum setup speed is exceeded, the device switches immediately to
the safe state. Contacts 23/24 are opened and when the lower parameterized standstill
speed limit is violated, contacts 13/14 are closed. The corresponding signaling outputs are
switched.
7.4.7.4

Setup speed undershot

If the parameterized minimum setup speed is undershot, the device switches immediately to
the safe state. Contacts 23/24 are opened and when the lower parameterized standstill
speed limit is violated, contacts 13/14 are closed. The corresponding signaling outputs are
switched.
7.4.7.5

Standstill speed exceeded

If the parameterized maximum standstill speed is exceeded, the device switches
immediately to the safe state. Contacts 13/14 are opened. The corresponding signaling
outputs are switched.
7.4.7.6

Start override time exceeded

If the parameterized minimum setup or automatic speed (depending on the switch position)
is not reached within the parameterized start override time t
immediately to the safe state. Contacts 23/24 are opened and when the lower parameterized
standstill speed limit is violated, contacts 13/14 are closed. The corresponding signaling
outputs are switched.

7.4.8

Parameterized monitoring times exceeded/undershot

7.4.8.1

Release delay time undershot

If "unlocked" is indicated at the MAG input before expiry of the release delay time t
device switches immediately to the safe state. The corresponding signaling outputs are
switched.
