OPERATING.
POWER SUPPLY : The I-53 circuit had to be supplied by a 12 VDC power supply perfectly stabilised and we suggest
you to not use rectifier or power supply not 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.
OPERATING : The I-53 module is an automatism to imitate the operating Bell clock, indicating hours and others.
Then, the hour relay will be activated each hour and the second relay will be activated each 15 minutes. The
module had been designed on a quartz oscillator basis, guaranteeing a maximum exactitude. It also includes
different options offering it a wide applications range.
HOW TO ADJUST HOUR : The module had a clock to control the automatism and to visualise the hour. Before to
activate the module in its definitive application, you have to adjust it. Then, you have to maintain pressed the
"enter" push button placed in the front of the module till the LD1 led will light on. At this moment both hour
displays will intermittently light and minutes display will be fixed.
When you are adjusting the hour, do not forget that you only modify fix displays because intermittent display are
in stand by. Then, you could firstly adjust minutes displays pressing on "up" and "Down" push buttons to increase or
decrease the number. If you maintain pressed any of these two button, the change will be quickly done.
