Time monitoring
4.3.6.4.1
Muting hold time
A muting hold time is active in combination with the exit monitoring function.
If one of the muting sensors in the hazardous area is no longer engaged and the sensor
gap monitoring of 0.5 s has been exceeded, the muting hold time of 4 s begins. ESPE
protection is bypassed within this time period and material or a means of transport can
pass through the ESPE without the machine stopping.
Muting ends if the muting hold time of 4 s has passed.
4.3.6.4.2
End of muting by ESPE
Important information
DANGER
Muting end by ESPE delayed or ineffective
If automatic measurement of the protective field width is configured and the protective
field is interrupted when the ESPE is switched on for the first time, the muting-end
function by ESPE is delayed or ineffective.
b
Configure a dynamic protective field width.
Principle of operation
Using the muting end by ESPE function, exit monitoring ends if the ESPE is clear again
(
1
) and a sensor gap monitoring of 0.5 s has passed. This results in a shorter muting
time and greater safety at the same time.

Hazardous area
The following applies to the muting end by ESPE function:
•
The entire length of the material and means of transport must be detected by the
muting sensors or the ESPE
•
Exit monitoring is ended too early if one of the muting sensors remains clear for
longer than 0.5 s, i.e. the sensor gap monitoring has been exceeded
