When displaying default information, the display screen will adjust to the set brightness level. If any key on the 239 keyboard is pressed or an alarm/trip occurs,
The brightness of the display screen will automatically change to 100%. If the default message time is set to off, the 239 display screen will dim to the set brightness 5 minutes after the last press of any key on the keyboard.
Note: Information brightness control is only applicable to devices equipped with VFD display screens.
Status indicator
-Trip: When 239 trips, the trip indicator light flashes. Any tripping condition (overload, short circuit, etc.) or serial tripping command sent through the communication port will cause tripping.
The indicator lights and trip relays can be manually reset through buttons, remotely reset using computer reset commands, or reset by turning off external reset inputs.
-ALARM relay is used for general alarm output. When the ALARM relay is working, the ALARM indicator light will light up.
If ALARM is programmed as unlocked, the indicator light will flash as long as the alarm status persists. After the alarm is lifted, the alarm indicator light goes out.
