ALIM01

The ALM01 circuit feeds the amplitude sensor SIND1 or SIND2 and makes it therefore possible to manage its reaction to the vibration so that any anomalous functioning can be detected (a too high or insufficient vibration).It is possible to regulate the level where the intervention will be required through a trimmer (T2 and T3).Moreover, thanks to the T1 trimmer it is possible to adapt the circuit to different types of vibrations.When the maximum vibration level is exceeded,the red Led indicator switches itself on (LD1) and the relay RL1 also goes off ( such alarm can be kept in auto retention by closing the contacts number  4 and 5 of the connector number 3; the system is reset by opening said contacts again).When the vibration is too low the green Led (LD2) switches itself off and the RL2 net stops being excited. The circuit is designed to function with tensions of  230V; if required, however, it can also be designed for tensions of 400V/115V. The whole of the control section is isolated from the electrical network. An (optional) instrument capable of indicating vibrations can be connected to contacts 4 and 5 of the connector.  This output V 0/10V can also be used for other purposes.

Usage instructions

Connect the amplitude sensor SIND1 to terminal 1 (+/green cable) and 2 (S/ black cable) and 3 (-/brown cable) of connector 2. Feed the circuit and bring the vibrator up to the maximum level of vibrations.Adjust trimmer T1 until the tension at terminal 4 and 5 of connector number 2, as measured with the voltmeter, reaches 10V+/-100mV (should the maximum vibration of 10V not be achievable, move bridge Y1 on High Gain), and check again that the tension is 10V+/-100mV. By adjusting trimmer T2, you should notice that, at a certain point, led LD1 (red) either switches itself on or turns itself off, if it was already on. Position the trimmer so that the led is swit ched off but near enough to the ignition level.Bring the vibrator at the minimum vibration level.  By adjusting trimmer T3 you will find an area where, by rotating in both directions, the green led LD2 will switch on and off. Position the trimmer so that the green led is switched on but near enough to the area where it switches itself off. Connect the (optional) indicating instrument, respecting the +/- priorities, to be able to visualise the width of the vibrations in %.
