CEBEK PM-11 Quick Start Manual

The PM-11module is a mono previous with relay output. When the module receive the Audio input signal the output will be
connected activating the relay.
Specially recommended for automatic applications where the audio signal or the voice is important.
It included a potentiometer to adjust the sensitivity and a protection against polarity inversion.

POWER SUPPLY.

The PM-11 circuit had to be supplied by a voltage between 9 and 15 V DC., perfectly stabilised to avoid
to damage the module.
Then, we recommended you the FE-2 power supply which has been developed to perfectly answer to the circuit needs.
Connect the positive of the power supply to the positive terminal indicated in the wiring map, then connect also the negative
of the power supply to the negative terminal indicated in the circuit. Verify that the assembly has been correctly done.

OPERATION.

Connect input signal and input terminal indicated in the General Wiring Map. In the installation, the distance
between the sound source and the PM-11 had to be as short as possible and as maximum30 cm. More over, you have to use
a low frequency shielded cable. The input signal could be the signal supplied by auxiliaries input as mixers, desks, etc.. but
this last have to be inferior than 300 mV. as maximumlevel.
Connect input and output with the power supply. Each time the module will receive an audio signal, it will connect the output,
activating the relay which will be connected till it stop to receive signal. If you wish to adjust the sensitivity level, you have to
use the potentiometer indicated in the General Wiring Map.

OUTPUT CONNECTION OF THE LOAD.

A. as maximumconsumption. The operating of this mechanism is the same as a switch, opening or closing its terminals to
allowor not to supply the module, with two (2) terminals NA and common. To obtain the reverse operating, you have to use
NC and Common terminals. In the Output connection paragraph, you could appreciate the typical connection for a devices
operating at 12 VDC and to operate at 220 VAC.
During the operating, and according to its load, it is possible that a fluctuation appear and/or an incorrect output operating. If
it is the case, you have to install a circuit against sparks (resistor or capacitor) between both relay contacts used for the
connection. (see the drawing)
