INTR ODUCTION TECHNOLOGY Step Three A. Application: The general purpose ultrasonic level switch pro- vides non-contact level detection up to 26’ or 8m with 3 relays.
Step Four Step Five CALIBRA TION A. Introduction: The switch has two modes, the RUN and CAL modes. In the RUN mode, the switch is operational and the relay(s) will energize or de-ener gize at the calibrated set point distances. In the CAL mode, the relay set point distances and states may be target-cal- ibrated into memory .
Step Seven Step Six CALIBRA TION B. Calibration T ools: T o target calibrate the switch set points, you will need the appropriate power supply (95-250 V AC or 12-28 VDC for DC version), tape measurer , flat reflective target such as a wall, and optional Omega box insert for use as a product holder .
Step Eight PR OGRAMMING Step Nine PR OGRAMMING C. Programming a High and Low Level Out of Bounds Alarm: After having powered the switch with the appropriate supply voltage, entered the CAL mode, selected a relay channel and erased any previously input set points, follow the below procedure: 1.
Step T en PR OGRAMMING E. Programming A utomatic Empty: After having powered the switch with the appropriate supply voltage, entered the CAL mode, selected a relay channel and erased any previously input set points, follow the below procedure: 1. Stretch the tape measurer out to the appropriate distance in between the switch and target.
A. Fitting Selection: Check the switch part number to determine the required fitting mount size and thread type. The switch is commonly installed in tank adapters, flanges, brackets or stand pipes.
