ASCO 430 Surge Protective Device (SPD)

Operation

LED Status Indicators

Figure 13:

Diagnostic Operation

Diagnostic LEDs are located on the front of the ASCO 430 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.

Indicator light ON = OK

Indicator Light OFF =

loss of surge suppression

on that phase and

Audible alarm ON =

Loss of surge suppresion

Indicator light ON (red) =

loss of surge suppresion

The audible alarm does not have a silence switch. Silence the alarm by

removing power from the SPD. The alarm indicates that the device needs

replacement by qualified electrical personnel.

INADEQUATE DRY CONTACT USE

• Do not supply more than 24 Vdc / 24 Vac and no more than a current

of 2 A.

Failure to follow these instructions can result in injury and equipment

damage.

The ASCO 430 series SPD device is provided with dry contacts. The

unpowered state shall be closed between the common wire and the normally

closed wire. This is also the alarm condition. The opposite state, closed

between the common wire and the normally open wire, indicates that power

is on to the unit and that no alarm condition exists (See Table 3). These dry

contact leads can be used for remote indication of the SPD operating status

to a computer interface board or emergency management system. Also,

these dry contact leads are designed to work with the SPD remote monitor

option described in the following section.
