Protection Functions and Alarms
Undervoltage limit (UVL)
This protection function is activated when you attempt to set the output voltage to a value that
is lower than the set undervoltage limit (the UVL trip point). In other words, it prevents you
from setting the output voltage to a value lower than the set limit. This function does not turn
the output off.
p. 37 , p. 48
You can use the CONFIG settings to limit the set UVL (CF15).
 Setting the UVL trip point
1
Press OCP•OVP.
The OCP•OVP key lights, and the OVP trip point and OCP trip point are displayed in
the display area.
2
Press OCP•OVP again.
The present UVL trip point is displayed.

While viewing the panel display, turn the VOLTAGE knob to set the UVL
trip point.
UVL setting range: 0 % to 105 % of the rated output voltage
4
Press OCP•OVP to finalize the setting.
Overheat protection (OHP), Overheat protection2 (OHP2)
This protection function is activated when the PWX series internal temperature rises to an
abnormal level.
• When the PWX series is used in an environment outside its operating ambient tempera-
ture range (0 °C to +50 °C [32 °F to 122 °F])
• When the PWX series is used with its air inlet and exhaust port blocked.
• When the fan motor has stopped.
If OHP2 is activated, turn the POWER switch off and on.
p. 46
If you do not fix the problem that caused the OHP or OHP2 to be activated, OHP or OHP2 will
be activated again even if you restart the PWX series.
Fan failure protection (FAN)
This function is activated when the number of fan rotations drops to an abnormal level.
