Page 4: Function
The number following the “WX” denotes the number of ST-15C Control Modules in the model. Each module is referred to as a “channel” and can monitor one sensor. Thus, an ST-15-240-WX10 can monitor 10 probes. The Scully part numbers for the various models are as follows: Model Part Number... -
Page 5: Power Requirements
Multi-Point Liquid-Level Detection System General Power Requirements The ST-15C-WX units consume less than 20 watts of line power per channel exclusive of controlled circuits and alarm devices. Models ST-15-115-WX operate from100-140 VAC, 50-60Hz mains power, Models ST-15-230-WX operate from 200-250 VAC, 50-60 Hz mains power. -
Page 6: Installation
ST-15-WX - Technical Manual Installation Mechanical Installation The ST-15-WX control unit must be installed in a NON-HAZARDOUS AREA. Normally the unit is installed in the control room of a storage tank arena. It may be installed outdoors in its weather proof enclosure. Conduit entries must be properly sealed to keep water out of the enclosure. - Page 7 Multi-Point Liquid-Level Detection System Installation 2.2.4.3 Probe Lead Wire Size The following table should be used to determine the appropriate wire size for ST-15-WX Control Module to sensor connections for distance between ST-15-WX and the sensor. Wire Size Feet (MM Maximum Run Length Feet (Meters) #16 (1.5) 400 (120)

Page 8: Operation
ST-15-WX - Technical Manual Operation ST-15-WX control units are shipped with each channel set to provide high level alarming (alarm output when liquid touches a probe). If your application requires alarm when a sensor becomes “dry”, typical for low level sensing, consult the factory for wiring instructions. When system power is applied, all high-level alarm channels will produce alarm outputs (red lamp on and alarm buss energize) until their associated thermistor probes warm up. -
