Page 8: General Information
Electronics Research Inc. motorized RF dual switch controller. Switch Controller Description The EC130 motorized RF switch controller is designed to operate a two industrial standard motorized waveguide or coaxial RF switch. The controller is contained in a 5.23-inch standard 19-inch rack mountable chassis. The front panel, shown in figure 1 below, has a key-lock selector switch and a red/green LED that indicates the RF switch’s interlock status.
Page 9: Rf Switch Requirements
Technical Manual for ERI Model EC130 RF Switch Controller TM_EC130 RF Switch Requirements The controller requires that the motorized RF switch DC voltage matches the controller DC voltage (either 12V or 24V available) The switch must have two form A (Normally Open Contact) limit switches in each of its two positions.
Page 10: Installation
This section describes how to do this. READ BEFORE APPLYING POWER The EC130 is capable of 12Vdc or 24Vdc operation of two switches. It is not capable of controlling both a 12Vdc and a 24Vdc switch simultaneously. VERIFY the control voltage required by the switch intended to control and toggle the slide switch on the back panel to the appropriate voltage before powering the switch controller.
