Menu
Allows you to temporarily change the High
Voltage Shutdown set point to another value
(such as system voltage) to test the high
voltage shutdown circuits.
1. Press ENTER and ALARM CUTOFF
(at the same time).
2. Press YES / + / i or NO / - to increment
or decrement, respectively, the High
Voltage Shutdown value displayed.
3. A WARNING appears. Press ENTER
and ALARM CUTOFF (at the same
