Muting
4.2.2 Muting with two sensors (one sensor pair), crossed placement, and an
a
dditional signal C1
The protection provided by the protective device is muted when the muting sensors are
activated in a defined sequence. The muting sensor (signal C1) must always be activated,
before both muting sensors in the first sensor pair (e.g. A1 and A2) are active (see section
“Additional signal C1” on page 49).
The following requirements must be met:
Condition Description
C1 & A1 & A2 Brief, to the start of the muting. C1 must always be activated,
before both muting sensors in the first sensor pair (e.g.
A1 and A2) are active.
A1 & A2 Muting applies as long as this condition is met.
