FACTORY SETTINGS
•
The muting module is set in the conveyor mode on delivery.
•
The maximum timing tmax allowed between SM sensors is set to 1 s on delivery.
It can be modified to the following values : 2 s, 4 s, or 8 s.
•
The setting of the timing tmax also sets the muting maximum duration
∆
max. In the
conveyor mode (delivery setting), the muting duration is set to 2 mn (on delivery). It can be
modified to the following values : 4, 8 or 60 mn.
•
Refer to chapter 2.4.2 SM inputs, to select tmax and
∆
max.
