K0/K1 (Panel key of this unit)
A/D of the key fails to function properly when the standard
value is deviated by ±2%. In this case, check the constant
of voltage dividing resistor, solder condition, etc.

9. AD DATA CHECK
This menu is used to display the A/D conversion value
of the main microprocessor which detects panel keys
of this unit and protection functions in % using the sub-
menu. During signal processing, the condition before
execution is maintained.
PS (Power supply voltage protection detection)
* When the value of PS, P2 and P3 is not at the normal
value level, the protection function works and the power
is turned off.
(Reference voltage: 3.3V=100%)
PS (PS1) Voltage detects: -24V, +5V, +6.3V
Normal value: 48.7 to 91.3 %
(1.6 to 3.0 V)
P2 (PS2) Voltage detects: +12V, +10V, D+12
Normal value: 63.9 to 88.2 %
(2.1 to 2.9 V)
P3 (PS3) Voltage detects: +3.3 V
Normal value: 66.9 to 85.2 %
(2.2 to 2.8 V)
* The normal value has been revised from 2.5V
(measured value) to 3.3V (indicated value) by the
voltage dividing resistor.
