I Undervoltage Alarm Function (Indication and Output)
When output voltage drop is detected, an alarm (a01) and lowest
output voltage value are indicated alternately. The preset value of
detection voltage can be changed in the setting mode.
(S8VS-06024@: The value of detection voltage is fixed at 20V)
Further, the alarm is output from the transistor ((11) DC LOW) to an
external device with the S8VS-09024A/B.
(Upon output voltage alarm: OFF; with no continuity across (11) and
(13))
:
In the case that the
output voltage drops
below the set value (19V)
and an alarm is issued
Note: 1. Operation begins after about two seconds since the AC
power is supplied.
2. The alarm is not indicated in the setting mode.
3. Press the ((8) Mode Key) after the output voltage is re-
stored, to reset alarm indication.
4. The undervoltage alarm function monitors the output termi-
nal voltage of the power supply unit. To check the voltage
accurately, measure the voltage at the load end.
