With each impulse, relays will be connected one after one, and disconnecting the previous one. The sequence could be produce by external impulses or thanks to an internal oscillator. The oscillator is adjusted with a potentiometer inserted in the PCB. It includes reset output, protection against polarity inversion, indicator output led and terminals to connect it. Do not forget to read all the information sheet in order to obtain a perfect operating of the module. OPERATING POWER SUPPLY. The I-203 circuit had to be supplied by a 12 VDC power supply. Then, we recommended you the FE-2 power supply which has been developed to perfectly answer to the circuit needs or a 12 V batteries for mobile applications. Install a fuse and a switch as it is indicated in the drawing. Both are obligatory to guarantee a correct protection of the module as well as for your own safety as it is required by theC marking. 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. See the general wiring map. The module has a switch indicated as INT-1. Thanks to this switch you could select between automatic operating (controlled by the internal oscillator) and manual operating which be externally inserted. Regarding manual operating. you have to place (in the switch INT-1) the contact N1 in ON position and the contact N2 in OFF position. Do not place permanently both contact in the same position to avoid to damage the module. See the drawing. Connect a push button to the terminal indicated as impulses input (See General wiring map). If you have to connect a clock signal from an other apparatus, you have to respect their polarity and verify that it is a 12 VDC signal. When the push button is installed, after each pressure relay will be activated one after one, and disconnecting the previous one. Regarding automatic operating. you have to place (in the switch INT-1) the contact N1 in OFF position and the contact N2 in ON position. Do not place permanently both contact in the same position to avoid to damage the module. See the drawing. Adjust the speed using the potentiometer inserted in the PCB to adjust the frequency. After each pressure relay will be activated one after one, and disconnecting the previous one. REST. See the general wiring map. Connect a push button to the terminal indicated asRese. Each time you press this push button and independently of the activated relay, the module will come back at the beginning of the sequence (to the first relay) until you stop to press therese push button.GENERAL WIRING MAP. OUTPUT. CONNECTION OF THE LOAD. The output Module (I-55) is controlled by a relay, allowing any load until 5 A. as maximumconsumption. The relay has 3 output terminals the normally open at quiescent (NA), the normally closed at quiescent (NC) and the common. The operating of this mechanismis the same as a switch with two (2) terminals NA and common, if you wish that the output will be activated during the timer, or between the NC and the common to obtain the reverse operating. VDC and to operate at 220 VAC. OUTPUT. DO NOT FORGET. When the module is working and according to its load, it could happen an incorrect operating of the output. If it is the case, you have to install a circuit between 2 relay s contacts used for the www.cebek.com - sat cebek.com
