LED Status Indicators
Diagnostic LEDs are located on the front of the ASCO 360 SPD device.
They operate as follows:
• Verify that all phase voltages are present. If any of the LEDs are not
illuminated, the device may not be installed correctly. Check the power
supply and service voltage. Upon energizing the SPD, check the LED status.
• If all of the LEDs are illuminated, surge suppression is operating.
• If one or more LEDs are not illuminated, there is a loss of surge
suppression on that phase.
•
If an inoperative condition occurs the device must be replaced by qualified
electrical personnel.
