5. PROTECTION SETTING
This menu is used to change the protection setting value.
The change is effective in this menu only. A set value can
be specified between 0 – 255 (0V – 5V).
Operation:
Change the digit with the “EDIT” key.
UP / DOWN with the TUNING MODE / MEMORY key.

The PS protection LO level threshold value can be set.
Protection operates when the voltage value of the de-
tection terminal falls below this value.
The PS protection HI level threshold value can be set.
Protection operates when the voltage value of the de-
tection terminal exceeds this value.
The DC protection LO level threshold value can be set.
Protection operates when the voltage value of the de-
tection terminal falls below this value.
The DC protection HI level threshold value can be set.
Protection operates when the voltage value of the de-
tection terminal exceeds this value.
The TEMP protection HI level threshold value can be
set.
Protection operates when the voltage value of the de-
tection terminal exceeds this value.
