The CTC061-RT-242-WW from SCS is a WS Aware workstation monitor with standard remote terminals, relay out. It works with dual wrist straps that have a standard 3mm audio mono plug. It verifies proper wearing of a wrist strap by measuring an operator’s resistance. It monitor detects body voltage and alarms if it exceeds the preset level. Alarm thresholds for body resistance and body voltage are set at the factory but can be changed in the field. It provides independent monitoring of four grounds - two tool grounds and two mat grounds. Red LEDs indicate that when wrist strap fails or when proximity sensor fails or when wrist strap is incorrectly plugged into the visitor’s jack, green LEDs indicate that wrist straps are properly connected and worn and power LED indicates that WS aware workstation monitor is on.
