Over Current mode
: When the current load presented by the connected appliances exceeds the
setting on the Max. Amps switch, the unit will switch to Over Current mode. The power will be switched
off to the 8 outlets. The red LED in the OFF switch will flash. The LCD will display the protected current
value. The Over Current icon will flash and the audible alarm will sound. Remove the appliance(s) which
is causing the over current power draw or readjust the Max. Amps value to a higher setting. Then press
the OFF key and then the ON key to turn the power back on.
4.
Abnormal Voltage mode
: When the voltage presented at the wall outlet if over or under the normal
voltage range, the unit will switch to Abnormal Voltage mode. The power will be switched off to the 8
outlets. The red LED in the OFF switch will flash. The LCD will display the protected voltage value. The
Abnormal Voltage icon will flash and the audible alarm will sound. When the AC line voltage delivered
by the wall outlet returns to a normal range and is stable for at least 3 seconds, the unit will switch back
to normal mode and restart power immediately. The unit will enter Abnormal Voltage mode if the AC line
voltage is over normal by 13% or under normal by 18%. The unit will switch back to normal mode when
the AC line voltage returns to +10% to -15% normal.
5.
Over Load mode
: The unit contains dual redundant over load protection circuits; an electronic control
breaker and a traditional NFB (No Fuse breaker).
a.
Electronic control breaker
: When the current load presented by the connected appliances
exceeds 15 Amps, the unit will switch to Over Load mode. The power will be switched off to the
8 outlets. The red LED in the OFF switch will flash. The Over Load icon will flash and the
audible alarm will sound. Remove the appliance(s) which is causing the over load power draw.
Then press the OFF key and then the ON key to turn the power back on.
b.
NFB (No Fuse breaker)
: When the NFB detects an over load condition, it will set and cut off
power to the unit. This will cut off power to the 8 outlets as well as the LED’s and LCD display
panel. The unit will be totally without power. Check and remove the appliance(s) causing the
over load, then press the NFB button to reset the breaker.
6.
Ground OK, Wiring OK detection
: When you connect the unit to a wall outlet, the unit will check the
structure wiring to determine and wire faults. The unit checks the Line, Neutral and Ground wiring.
Under normal conditions, “Ground OK” and “Wire OK” icons will display on the LCD. If Line or Neutral
are in the wrong positions, the “Wire OK” icon will disappear. If the Ground wiring is not correct, both
“Ground OK” and “Wire OK” icons will disappear.
7.
Surge Protection
: The unit features a self-test function. If the surge protection circuitry is operating
properly, the LCD display with indicate with the “Surge OK” icon. If the surge protection has failed, the
“Surge OK” icon will disappear.
8.
EMI Filter
: The unit features a built-in EMI (electro-magnetic interference) filter to reject noise from the
AC power line.
9.
Internal Switch Self Test
: The LCD will flash the “REPLACE” icon and sound an audible alarm if the
unit detects that the internal relay switch has failed.
