Vacuum Ejector with Solid State Timer

Transcription

1 Vacuum Ejector with Solid State Timer Incorporates solid state timer function for release valve control (Timer setting with PLC is unnecessary) Timing Chart OFF Suction command ON Suction output OFF ON OFF Release output ON Timer period 2 to 2, ms Note) When power is supplied, release output is performed once for the time period only. Allows sharing of switch/valve power supply, and single line for suction signal (Valve wiring is unnecessary) Timer can be easily adjusted without programming (Reduction of the load of PLC) ZA ZX ZR ZM ZMA ZQ ZH ZU ZL ZY ZF ZP SP ZCUK AMJ AMV AEP HEP Related Equipment 19 Courtesy of Steven Engineering, Inc.-23 Ryan Way, South San Francisco, CA Main Office: (6) -92-Outside Local Area: ()

7 Vacuum Ejector With Solid State Timer /, Standard Supply Pressure: M.3 MPa How to Read Graph l/min (ANR) l/min (ANR) l/min (ANR) l/min (ANR) Flow characteristics are expressed in ejector vacuum pressure and suction flow. If suction flow rate changes, a change in vacuum pressure will also be expressed. Normally this relationship is expressed in ejector standard supply pressure. In graph, Pmax is max. vacuum pressure and Qmax is max. suction flow. The values are specified according to catalog use. Changes in vacuum pressure are expressed in the order below. 1. When ejector suction port is covered and made airtight, suction flow is and vacuum pressure is at maximum value (Pmax). 2. When suction port is opened gradually, air can flow through (air leakage), suction flow increases, but vacuum pressure decreases (condition P1 and Q1). 3. When suction port is opened further, suction flow moves to maximum value (Qmax), but vacuum pressure is near (atmospheric pressure). When vacuum port (vacuum piping) has no leakage, vacuum pressure becomes maximum, and vacuum pressure decreases as leakage increases. When leakage value is the same as max. suction flow, vacuum pressure is near. When ventilative or leaky work must be adsorbed, please note that vacuum pressure will not be high.

12 Specific Product Precautions Be sure to read before handling. Refer to front matters 3 and 39 for Safety Instructions and pages 44 to 46 for Vacuum Equipment Precautions. Warning Mounting 1. Do not drop or bump. Do not drop, bump or apply excessive impact (1, m/s 2 ) when handling. Even if the switch body is not damaged, the switch may suffer internal damage that will lead to malfunction. 2. Hold the product from the body side when handling. The tensile strength of the power cord is 49 N, and pulling it with a greater force can cause failure. 3. When handling the product, never move or loosen the switch assembly or the switch assembly mounting screws. Warning Wiring 1. Do not allow repeated bending or stretching forces to be applied to lead wires. Wiring arrangements in which repeated bending stress or stretching force is applied to the lead wires can cause broken wires. Warning Pressure Source 1. switches There will be no change in performance if a pressure of approximately. MPa is applied momentarily (when releasing vacuum), but care should be taken that pressures of.2 MPa or more are not applied on a regular basis. Warning Operating Environment 1. The product cannot be used in a strong magnetic field. 12 Courtesy of Steven Engineering, Inc.-23 Ryan Way, South San Francisco, CA Main Office: (6) -92-Outside Local Area: ()
