10. AD DATA CHECK/FAN TEST

This menu is used to display the A/D conversion value of
the terminals which detects panel keys of the main unit
and protection functions in % using the sub-menu. During
signal processing, the condition before execution is
maintained.
* The figures in the diagram are given as reference only.

DC/PS (protection detection)

DC: DC protection value
Normal value: 17 to 29 (Reference: 5V=100%)
If DC is out of the normal value range, the protection
function works to turn off the power.
PS: Power supply voltage protection value
Normal value: 12 to 26 (Reference: 5V=100%)
If PS is out of the normal value range, the protection
function works to turn off the power.

THM/Fan (temperature detection/fan drive level)

THM: Temperature detection value
Normal value: 30 to 147 (Reference: 5V=500%)
If THM is out of the normal value range, the
protection function works to turn off the power.
Fan: Current fan drive level on the left and the past fan
drive history on the right.

REC-OUT
Not applied to these models.

IMP SW/POWER LIMIT (Impedance/power limiter detection)

IMP: 8 or 6 ohms impedance switch setting (U, C models)
PL: Power limiter detection value (Reference: 5.0V=255%)
The voltage value of pin No. 91 of IC242 is displayed.
The port (pin No. 4 of IC242) output is controlled by
using the input voltage.
value of pin No. 91 of IC242.
When higher than VthH, the port output is changed
from H to L.
When lower than VthL, the port output is changed
from L to H.

K0/K1 (Panel key of main unit) (Reference: 5V=100%)
A/D of the key fails to function properly when the standard
value is deviated. In this case, check the constant of
partial pressure resistor, solder condition, etc. Refer to
table 1.

When K0/K1 menu is selected, keys become non-
operable due to detection of the values of all keys.
However, it is possible to advance to the next sub-
menu by turning the VOLUME of the main unit. When
using this function, note that turning the VOLUME more
than 2 clicks will cause the volume value to change.
