Why is the desired alarm value not displayed on my Omron Surge Protector?
If the desired alarm value is not being displayed on your Omron Surge Protector, it is because the setting is not allowed in the present protection level. Change the protection level setting.
Why is the Omron Surge Protector circuit cut off as soon as power is supplied?
If your Omron Surge Protector circuit is cut off as soon as power is supplied, even though it wasn't designed for such a high current, the abnormal current tripping type might be set to 'instantaneous'. This setting detects abnormal current very quickly, potentially cutting off the circuit due to excessive current during equipment operation. You can either change the abnormal current tripping type from instantaneous to standard or raise the current tripping value. Alternatively, if there are a lot of devices connected to the output, which increases the operating current, use the S8M's startup sequence function to delay the connection of some devices.
How to clear alarm display on Omron Surge Protector?
If an alarm was triggered on your Omron Surge Protector and you've fixed the issue that caused it, but the alarm display won't clear, it's because the S8M retains the alarm display even after the problem is resolved. To clear the alarm, press the Reset Key for at least 3 seconds.
What to do if the Omron Surge Protector output is cut off immediately in Test Mode?
If the Omron Surge Protector output is connected in Test Mode, but it's cut off immediately and can't be reconnected, check the status indicator to see if it's lit red. This indicates the current may be higher than the tripping current. Look for output wiring problems. If no problems are found, press the Reset Key for at least 3 seconds.
Why does the Omron Surge Protector display “- - -” for peak output current?
If the peak output current is not displayed and the display shows “- - -” on your Omron Surge Protector, it is because the current may have exceeded the measurable range. Clear the peak output current in Run Mode.
How to enable branch outputs on Omron Surge Protector?
If the branch outputs of your Omron Surge Protector are not working, it is because all branch outputs are disconnected in the default settings to ensure safety. Switch to Test Mode and connect the desired branch outputs.
Why does the Omron Surge Protector output cut off immediately after being reset?
If the output was reset on your Omron Surge Protector, but it was immediately cut off again, it means that the original cause of the cut-off may not have been eliminated. Eliminate the problem that caused the cutoff and press the Reset Key for at least 3 seconds.
How to clear the run time alarm on Omron Surge Protector?
If the run time alarm was output on your Omron Surge Protector, so the equipment was checked and other parts were replaced, but the alarm could not be cleared, it is because the S8M continues adding to the run time. Clear the run time and then press the Reset Key for at least 3 s. The alarm can also be cleared by increasing the run time value and then resetting.
What to do if alarm output went OFF and cannot be cleared on Omron Surge Protector after setting overvoltage and undervoltage alarms?
If the S8M was switched to Run Mode after setting the overvoltage alarm and undervoltage alarm, and the alarm output went OFF and cannot be cleared on your Omron Surge Protector, the undervoltage and overvoltage settings may have been reversed. Switch to Setting Mode and check the settings.
What to do if Omron Surge Protector display is flashing 'ON' in Test Mode but no power is supplied?
If the Omron Surge Protector display is flashing “ON” in Test Mode, but power isn't being supplied by the outputs, it means the S8M is waiting to turn ON the outputs. Pressing the Mode Key will connect the output and supply power. When power is being supplied, “OFF” will flash on the display.
