5.13 Safety Limiter Settings Page
Figure 140 - Safety Limiter Settings
The Safety Limiter provides an independent high temperature cutout capability to ensure protection
against over-heating of the EHT or the workpiece. It uses a separate temperature sensor input and
controls an independent external contactor. If the measured temperature exceeds the setpoint, the
Safety Limiter will open its output relay and de-energize the Heat Trace.
