By default CEM3 in Sensor 3 racks will give a High Voltage Warning at 140VAC for 100-120VAC systems and 250VAC for 230-240VAC systems.
Description/Explanation of Issue
In some systems this can mean that a High Voltage warning may not occur until the voltage is already in dangerous levels, or you may be in a situation where you do not want to be warned (ETC advises against setting this warning too high to avoid a notice of High Voltage). For these reasons, this threshold can be adjusted. The range can be set between 60-300VAC.
- Push the Setup key
- Use the wheel to scroll to [Rack] and press enter.
- Use the wheel to scroll to [Volt High Warn] and press enter.
