1、REXA XpacQUICK START GUIDEX2 DesignREXA Electraulic? ActuatorIMPORTANT READ THIS FIRSTThese are MINIMUM Setup Parameters for a Standard Actuator/Drive with a 4-20 mA Control Signal. For more detailed setup instructions, please refer to the Installation and Operation Manual, IOM.Once th e REXA Actuat
2、or/Drive is mounted, this guide can get you up and running quickly. Refer to Drawing D97904-D; it will provide information on:? Power Requirements Refer to Nameplate Rating on the Control Enclosure door.? Wiringo Control Signal Connectiono Actuator Feedback Connectiono Actuator Module Connection? Mi
3、nimum Setup ParametersGROUNDINGProtective Earth GroundA dedicated Protective Bonding Conductor (Protective Earth, PE) must be provided. The conductor must be connected to the terminal labeled PE at the Power Input Terminal. Conductor must be capable of safely carrying the maximum fault current that
4、may be imposed upon it. Protective bonding provides protection against electrical shock.A Protective Earth conductor should be provided at both Control Enclosure and Actuator.MAIN POWERThe Main Power requirements for the Control Enclosure/Actuator vary according to model. The Main Power requirements
5、 are given as part of the Nameplate Information in the lower right corner of the control enclosure. If no control enclosure is used, the nameplate will be attached to the backplane on which the Electronics is mounted.In general, the Main Power requirements are given in Table 1. Information provided
6、in Table 1 is for reference only. The Nameplate rating takes precedence.Table 1MaximumModule SizeIncoming Voltage*VA RatingCurrent RequiredD-Pump208-240 Vac, 1? 50/60 Hz10.0 amp2400*If another voltage is to be used, an External Step Up/Down Transformer must be used.SUPPLY DISCONNECT DEVICETo comply
7、with IEC 61010-1, Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use,a Supply disconnect device with the proper ratingMUST be provided. The supply disconnecting device shall disconnect(isolate) the Control Enclosure/Actuator from the supply when required. The su
