Operation principle

5.5.6.1

Operating modes

Collecting mode
LEDs that are used in collecting mode of operation are accumulated (latched on) continuously until
the unit is acknowledged manually. This mode is suitable when the LEDs are used as a simplified
alarm system.
Re-starting mode
In the re-starting mode of operation each new start resets all previous active LEDs and activates only
those, which appear during one disturbance. Only LEDs defined for re-starting mode with the latched
sequence type 6 (LatchedReset-S) will initiate a reset and a restart at a new disturbance. A
disturbance is defined to end a settable time after the reset of the activated input signals or when the
maximum time limit has elapsed.
5.5.6.2

Acknowledgment/reset

From local HMI
Active indications can be acknowledged/reset manually. Manual acknowledgment and manual reset
have the same meaning and refer to a common signal for all the operating sequences and LEDs.
The function is positive edge triggered, not level triggered. Acknowledgment/reset is performed via
