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 second 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 any of the SMs inputs. Physically, the 2
sensors must be slightly apart.
•
If both sensors are maintained while the press tool is at the top dead center, the
muting sequence stops when the next press cycle starts or when the ∆max muting
timing has passed.
•
If the ∆max muting timing has passed, the muting module must be restarted before restarting
the press (refer to chapters 2.4.5. Manual restart of the module and 4.8.2. Restart input).
Hydraulic presses
In this example, A pair of limit switches SM1&SM2 is used to start the muting sequence,
and another pair of limit switches EM1&EM2 is used to stop the muting sequence (on a
different machine, the sensors could also be photoelectric controls, ultrasonic sensors
or inductive proximity sensors). Correct operation of these sensors is monitored by the
muting module.
