5-4-7. How to rotate display panel by 90 degrees (for vertical installation)
The panel operation unit of the PSF Series may be rotated by 90
degrees to ensure easy operation in either horizontal or vertical
installation. Hold the encoder and rotate the panel operation unit
while pressing the ROTATE key below the encoder.
A
“click” sound is heard and the panel operation unit is locked.
CAUTION
Be sure to confirm that the POWER switch is off before rotating the
display panel.
If the display panel is rotated with power on, the set value may change
due to rotation of the encoder. Be careful.

5-4-8. How to invalidate on-panel operations (Key lock function)
It is possible to invalidate operations conducted on the panel by
pressing the FAST/LOCK (3s)/LOCAL key on the left of the encoder.
Hold this key for three seconds or more to lock the keys. The keys
are locked when the LED on the side of the key goes on red. To
cancel the key lock condition, hold the FAST/LOCK (3S)/LOCAL key
for three seconds or more.
CAUTION
This key serves as the FAST, LOCK (3s), and LOCAL keys. Even if the
power supply unit is in the FAST state (green), the FAST state is canceled
and the normal (SLOW) state is restored when the key is reset in order to
avoid danger. Even in the key locked condition, the OUTPUT key is only
functional to avoid danger. (output off only)
