11. SYSTEM MONITOR
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. Signal processing is maintained in the status
before execution.
When K0/K1 menu is selected, keys become non-op-
erable due to detection of the values of all keys. How-
ever, it is possible to advance to the next main menu
by turning the PROGRAM knob of this unit.
* The figures in the diagram are given as reference
only.
DC1/DC2 (Protection detection)
DC: DC detect protection value (Normal value: 3 to 33)
* If DC is out of the normal value range, the protection
function works to turn off the power.
(Reference voltage: 5V=255)
PS1/PS2/PS3 (Protection detection)
Power supply voltage protection value (Normal value:
PS1: 53 to 104, PS2: 52 to 83, PS3: 83 to 103)
PS1: Detects ±B1, ±B2, FAN LOCK.
PS2: Detects ±12RY, ±12A, ±7A, +5A, +3.3HD.
PS3: Detects +2.8DSW, +4.3DSW, +6.3DSW, +2.0DSW,
+9VA, ±5VA.
* If PS is out of the normal value range, the protection
function works to turn off the power.
(Reference voltage: 5V=255)
TM1/TM2/TM2 (Temperature detection)
Temperature detected value
(Normal value: 10 to 83)
(Normal value: 10 to 78) L model
TM1: Detects the temperature of the heat sink at the right
side.
TM2: Detects the temperature of the heat sink at the left
side (power transformer side).
TM3: Detects the temperature of the power transformer.
(Reference voltage: 5V=255)
