Installation Guide / User Manual
Protection Loss
When the SPD detects a Protection Loss this animation will be shown. It will
remain on screen until acknowledged by an operator. Any subsequent events
that occur while the disconnection event animation is on screen will be
registered and queued for acknowledgment. Along with displaying the
disconnection animation, the Audio alarm will sound, and the dry contacts will
change state. A corresponding LED will also change state during a Protection
Loss. A loss of protection means that either the SPD has detected the loss
of a system phase or that one of the protection modes has permanently
disconnected and requires attention. As long as a fault state exists the dry
contacts will remain disengaged and the corresponding LEDs will be in a non-
green state. If the Protection Loss event was caused by a phase loss, returning
the phase will return the system to a GOOD state.
However, if the Protection Loss event was caused by a Mode disconnection, the
SPD will stay in the faulted state indefinitely. Pressing the CENTER button will
acknowledge the event and clear the alarm state. The Main Screen will be
showing the details for the Protection Loss.
Neutral to Ground Fault Event
When the SPD detects a Neutral to Ground Fault Event (NGF) this animation will
be shown. It will remain on screen until acknowledged by an operator. An NGF
is detected when greater than 20 volts has been detected between Neutral and
Ground. Any subsequent events that occur while the NGF event animation is on
screen will be registered and queued for acknowledgment. Along with displaying
the NGF animation, the Audio alarm will sound. Pressing the CENTER button will
acknowledge the event and clear the alarm state. The Main Screen will be
showing the details for the NGF.
The SPD may be exposed to a NGF for several minutes. The NGF animation
will be displayed as soon as a NGF has been detected. If an operator is able to
acknowledge the event while a NGF condition still exists, the screen to the left
will be displayed.
Power Outage
Should the SPD be subjected to a full power outage this animation will be
shown once power is restored. It will remain on screen until acknowledged
by an operator. Any subsequent events that occur while the power outage
event animation is on screen will be registered and queued for acknowledgment.
Along with displaying the power outage animation, the Audio alarm will
sound, and the dry contacts will change state. Pressing the CENTER button
will acknowledge the event and clear the alarm state. The Main Screen will
be showing the details for the Power Outage.
This SPD’s timekeeping is equipped to survive several days of a power outage.
When power returns the SPD will record the date and time of the power loss and
when power was restored. Should the SPD be exposed to an extended power
outage the SPD’s timekeeping may have been affected. It is highly recommended
that the time and date be updated.
Due to the nature of installations, were power may be cycled several times. The
Power Outage alarm is suspended. It is automatically engaged after the SPD has
been continually powered for 1 hour.
