FACTORY SETTINGS
•
The muting module is set in the conveyor mode on delivery.
•
Refer to chapter 2.4.1 Selection of the appropriate mode, to select the press mode.
•
The maximum timing tmax allowed between SM sensors is set to 1 seconde on
delivery. For machines different than presses, 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 press
mode, the muting duration is set to 1 mn on delivery. For machines different than presses, it can
be modified to the following values : 2, 4 or 60 mn.
•
Refer to chapter 2.4.2 SM inputs, to select tmax and ∆max.
TIMING CONDITIONS
•
The 8 ms minimum time difference between the two SMs inputs guarantees the
detection of a permanent short circuits of one of the SMs inputs. Physically, the 2
sensors must be slightly apart.
•
The activation of both EMs sensors must occur before the ∆max muting timing has
passed otherwise the muting module need to be restarted before restarting the press (refer to
chapters 2.4.5. Manual restart of the module and 4.8.2. Restart input).

Because of the overtravel, the release and second actuation of the sensor SM1
interrupts the muting sequence. The intrusion of an object inside the dangerous
area immediately stops the machine.
