Wiring the output parameters

Muting must be displayed through an LED (output parameter

MAct). This

LED must be safely monitored to ensure it functions correctly (EN 61 496-1
Section 7.1, 06/98).
For this reason the muting LED should be connected to a dual-pole output
(e.g. PSS DI2O Z module) or use standard function block SB097.

Operating modes

Terminology

Muting ON
“Muting ON” is the switch condition for switching on the muting function. If
muting is switched on, the output parameter

MAct will be high and time

monitoring will be running (input parameter

TMut / TOPD).

Muting OFF
“Muting OFF” is the switch condition for ending the muting function. When
the muting function is ended the output parameter

MAct will be low.

Muting Start-Up
“Muting Start-Up” is the switch condition for switching on the muting
function when the PSS is cold-started or reset using the key switch (input
parameter

RSET).
