Brake and clutch Feeder MA-800 Brand Macesa Description of equipment

Photoelectric Amplifier MA-800, can run through the mechanical cycle (garnish-brake levers) by micro switches, proximity switches or PLC and / or photoelectric head TS-80 (or another of the same characteristics). The coils of clutch and brake must be 24 VDC. And 1.5 Amp. Max. The impulses of 90 V. Overvoltage and demagnetization of the clutch / brake are adjustable in timing and intensity through four multi-turn potentiometers located on the printed circuit 1 of control (Maximum time 90 msec.). At the base are located, a 1 Amp fuse. And two 2 Amp fuse. That protect the entrance to the 1 Amp transformer. And the output of the 2 transistor amp. When the clutch lever (terminal 13 and 10) connect, the connection is off the clutch and brake. Automatically produces the movement of material, until the end of the cycle (the clutch lever has disconnected), connect the brake lever (terminals 13 and 11) stopping the material, this situation is the so-called mechanical cycle. The clutch and brake cams, they have a small area (approximately 30 º) and the pulses from micro switches, sensors, or robots are of short duration. Although both match the two input pulses (clutch and brake) will not happen because the MA-800 amplifier includes protection for the item you are in labor continues to receive voltage and the other channel is locked until you remove the anomaly . Working with the photoelectric head TS-80, the movement of material occurs also by connecting the clutch lever being unemployed by the signal that sends the head, produced by the brand name printed on the material to be controlled. Blinded cam (terminals 12 and 13) is insurance whose mission is to block any signals to send the head out of the operating point, in other words, limits the degree cycle time machine that has the head to activate brake. As his work has normally closed to open a few inches before the head is to read the mark to identify and may close again occur immediately after the stop of the material. The head switch Focus (terminals 3 and 4) is provided for if you want to work in unmarked or anonymous material, and by a switch to cut power to the head spot lighting. The MA-800 amplifier incorporates five leeds pad to display the proper functioning of the cams (3 leeds green) and the element that is currently working on (2 leeds red).   More details of this article
