SENSOR FAILURE
•
If a sensor SM fails, the muting sequence is not allowed. In this case the muting
lamp remains permanently off (refer to chapter 4.8.3 Muting lamp output).
•
After clearing the detection field, the muting module can be restarted either by
pressing the restart push-button in the press mode or by using the override function in
the conveyor mode. However, the next muting sequence will not be allowed.
•
Normal operation can be achieved by switching the power off, replacing the
defective SM sensor, switching the power on and restarting the module (refer to
chapter 2.4.5 Manual restart of the module).
Setting the maximum timing tmax of sensors SMs
Simultaneous action of the sensors SMs is monitored by the module which detects
possible failure of a sensor.
FACTORY SETTINGS
•
The maximum timing tmax 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. In the conveyor mode
(factory setting), the muting duration is set to 2 mn on delivery.
The setting is done with 2 switches ST3 located inside the module. The removal of the
upper terminal strip eases access to the switches ST3 :
