What to do if the front panel controls are non-functional on TDK-Lambda Power Supply?
If the front panel controls on your TDK-Lambda Power Supply are not working, the power supply might be in Local-Lockout mode. Turn off the AC input power and wait until the display turns off. Then, turn the AC input power back on and press the front panel REM/LOC button.
