Appendix One

Alert Messages

The SP PRO is continuously measuring and monitoring the power system to ensure correct system operation at

all times. When the SP PRO detects a problem with the power system it then:

1. Displays a message in the “Attention Required” area in SP LINK (In the Data View - Now tab).

2. Creates an entry in its data log memory. This data can be downloaded from the SP PRO and viewed in the

EVENTS tab of the Performance Data Viewer.

The table in this section outlines all the SP PRO ALERT type event messages, the most likely cause and

possible remedies.

Only the ALERT events are listed - They are listed in alphabetical order.
