Simple pulse controller 20 Road I. Features: controller using industrial-grade chips as the control; the controller on the printed circuit board has a clear set a flag, can be easily controlled instrument settings; control device is provided on the output side work instructions for each output point, you can quickly determine the status of the output point; a control device with manual operation button, can easily debug the equipment, operations; controller with waterproof shell structure, with waterproof connectors, available at outdoor, dust environments; controller with removable printed circuit boards dedicated terminals, wiring can be easily performed. Second, the model significance: Third, technical indicators: Number of outputs: 1-20 road options; supports remote start / stop control; input voltage:? AC 50HZ 180-240V; drive capacity: AC 220V 1A; Dimensions: 248 × 188 × 100mm; 4 Parameter setting range: Pulse width: setting range is 0.05 to 0.80 seconds; pulse interval: Set the range of 095 to 120 seconds; five panel indicates: 2) Controller installation Figure: Six? , Wiring: Wiring: 1) J4 to 220V AC input terminals (L, N); 2) J6 for the power signal (dry contact), external start signal or differential pressure switch; 3) J10 to two output wiring public end; 4) 1-20: Pulse valve signal output terminal; when seven different effective output terminal wiring large ones when selecting a different way of outputs in 1 to 20, the output terminals in sequence, but can also be Direct light emitting diode output instruction directly determined by the runtime; Eight, Installation: Because FC-A-20 type pulse controller using waterproof transparent plastic shell, effectively isolating the impact of external dust control chip can be mounted in the dust concentration higher occasions. Installation is as follows: 1) control device Dimensions: Nine, Instructions: 1) control principle: control device using LSI structures made using two potentiometers adjust time two important parameters: pulse width, pulse interval ; with selectable number of pin structure can be achieved within 10-20 road of outputs freely adjusted, the specific location pins see location printed circuit boards. 2) parameter setting and modification: The FC-type control device is powered without any action automatically according to the latest set parameters to implement controls. There are three main controller status - standby, running, maintenance state. Standby: control after instrument power on. If not the boot and conditions (start signal is off), the system will go into standby mode. Operating status: power control device, and meets the conditions of the boot after entering the power running, LEDs display the status of each output point. Maintenance Status: In normal operation the controller will automatically, manually convert two pins inserted on the right hand enters the maintenance state, then press the "Manual" button, the output will be shifted on all the way back until the plug needle into the left two exit manual state. Parameter modification status: any time, while slowly rotating the potentiometer, while observing the output LEDs lit situation can be pulse width / pulse adjustment interval.
