The cardboard being used to make the box must have a resistance of 170 Kg (375 lb.). 2.- When sending it to a Fagor Automation office for repair, attach a label indicating the owner of the unit, person to contact, type of unit, serial number, symptom and a brief description of the problem. 3.- Wrap the unit in a polyethylene roll or similar material to protect it. 4.- Pad the unit inside the cardboard box with poly-utherane foam on all sides. 5.- Seal the cardboard box with packing tape or industrial staples. Page: 8 - Installation Manual - NC-200 PB DESCRIPTION OF THE DIFFERENT MODELS (THEY MAY BE SELECTED WITH PAR64) A. Controlling only the final position of the bend. The foot switches and the hydraulic circuit are not controlled by this NC. The intermediate positions of the ram are detected by electrical microswitches. A1. Same as model "A" with footswitch treatment and outputs for governing the hidraulic valves for the 4 EXECUTION modes. The rapid approach feed is not managed. Especially indicated for conventional down-stroke machines. B. Same as model "A" with a linear encoder or potentiometric scale for decoding the intermediate ram or bed positions affecting the bending approach speed and depth: With outputs to relays or to a PLC: STOP - Top dead point overrun S9 S29 S28 Fast ram approach. Slow speed controlled by the footswitches. Ram retraction. With internal processing: (without external output). · · Going through "Y=sheet thickness" position to withdraw the X axis. Bend position reached to start bending timing on upstroke models that do not have a presostat. C- Control of the actual ram/bed position. With internal processing of all the intermediate positions. The footswitches control directly the position of the bending tool, Y axis. NC-200 PB - Install ...
