SENSOR FAILURE
•
If a sensor EM fails, the next muting sequence is not allowed even if the condition of
simultaneity between sensors SMs is satisfied. In this case the muting lamp remains
permanently off (refer to chapter 4.8.3 Muting lamp output).
•
Restarting the module either by pressing the restart push-button in the press mode
or by using the override function in the conveyor mode., will allow the performance of a
single muting sequence ONLY.
•
Resetting the module by switching off and on the power supply, will allow the
performance of a single muting sequence ONLY.
•
Normal operation can be achieved by switching the power off, replacing the
defective EM sensor, switching the power on and restarting the module (refer to chapter
2.4.5 Manual restart of the module).
