_.,,------------------------------------- PRESS For presses arranged with an air clutch, the <strong>Bliss</strong> Type #46H Combination Clutch and Motor Control is standard equipment. It is housed in an oiltight NEMA 12 enclosure with a hinged door that is interlocked with the disconnect switch. On the panel are mounted the fusible disconnect switch, dual voltage transformer, motor starter, secondary fuse, and the clutch control relays. Wiring between the components conforms to N.M.T.B.A. standards with all terminals clearly numbered. Vinyl wireways house all wires neatly and safely. The following are mounted in the side of the control enclosure on presses 22 thru 110; combination motor "Start-Stop" pushbutton; a 4-position key lock mode selector switch for "Off", "I nch", "Single Stroke", and "Continuous"; and a 3-position key lock selector switch for "Bar", "Bump", and "Off". The latter control is provided on all presses to enable power use of ~he unsticker. In addition to the key lock selector switch, a red warning light glows on the panel when the unsticker is out of its receptacle. 12 Standard operator's palm-type pushbuttons with ring guards are: "Run-I nch" (two), "Stop" (one!. "Top Stop" (one). A finger-type pushbutton "Continuous Preset" (one) is also standard. Two detector outlets for customer convenience, mounted in the side of the enclosure, are standard equipment. One outlet is arranged for "Top-Stop" and the other for "Stop". The control also includes a rotary limit switch of the make-and·break-contacttype, cam actuated; a double solenoid air valve with self'monitoring feature and remote recock for air clutch actuation. Control circuitry provides for "I nch" action whereby the slide will move only as long as both guarded palm buttons are held depressed; "Single Stroke" whereby the slide automatically stops at the top of its stroke even though both "Run" buttons continue to be depressed; and "Continuous Run" whereby, with the mode selector set for "Continuous", the press starts and runs when the "Run" buttons are depressed_ It is also necessary to depress the "Continuous Preset" finger pushbutton just prior to depressing the "Run" buttons for continuous operation. The rotary limit switch is adjustable for desired top·stop to suit different press speeds and weights of dies. The clutch control has been designed for long, trouble-free operation, with particular attention paid to the operator's safety, protection of the equipment, and adequate size of the components_ A preventive maintenance program, outlined inside the enclosure, has been developed to help maintenance engineers keep the machine in a safe operating condition. N.M.T.B.A. standards have been fo Howed throughout, including the wire size, panel location, and electrical component identification. All controls and circuitry are in full compliance with the ANSI B11.1-1971 Code, as we interpret it.
CONTRa S R <strong>Presses</strong> equipped with the "CKU" combination air friction clutch and brake are furnished with a rotary limit switch with external adjustment. A pull/turn knob provides all necessary adjustments for varying top-stop position. This feature is standard on all sizes from 22 to 110 tons. .J T E W.
