I-2
INFORMATION ABOUT THE OUTPUT :
During the operating mode and according to its load, it could happen a
fluctuation or an incorrect working of the output. In such case, you have to install an anti-spark circuit (100 nF/400V
Capacitor type X2 and 47 . ½ W resistor) between both contacts of the used relay, as it is indicated on the drawing.
OPERATING MODE :
The timing adjustment is done adjusting the potentiometer inserted on the PCB. At beginning you
have to place the potentiometer at the minimum, after you could adjust it accoridng to your wished time.
Once the time selected, the module I-2 could be activated according towdifferent modes: Activation by push button or
supplying the module. To activate the module thanks to the push button, you have firstly toinstall a quality push Button
between indicated terminals. See the General Wiring Map. Each time you activate it, and if the previous timing is completely
finish, the module will be activated, lighting the LED and exiting the relay duringthe selected time.
To activate the I-2 each time you supply the module, with out using the push button, you have to connect both terminals of
the JP1 jumper. Then, each time you supply the module, the timing will be automatically activated.
INSTALLATION OF THE EXTERNAL POTENTIOMETER :
If you wish to remove the potentiometer already inserted on
the PCB and install an external potentiometer, you have to firstly desold the resistor fromthe circuit. Then, install two
connection wires fromthe JP2 Jumper till the new potentiometer. This one has to be a Linear 4M7 potentiometer.
