Event codes
When the capacitor bank protection module
SPCJ 4D40 is linked to a control data commu-
nicator over the SPA bus, the module will pro-
vide time stamped event markings e.g. to a
printer. The events are printed out in the for-
mat: time, user specified text and an event code.
The events are generated on starts, trips, resett-
ings and output relay operations. Every func-
tion has their own code designation from E1...
E34.
Masking parameters can be used to inhibit event
generations from one or several functions.

An event buffer is capable to memorize up to
eight events. If more than eight events occure
before the content of the buffer is send to the
communicator an overflow event "E51" is gen-
erated. This event has to be resetted by writing
a command "0" to parameter C over the SPA-
bus.
More information about the serial communi-
cation over the SPA-bus can be found in the
pamphlet "SPA-BUS COMMUNICATION
PROTOCOL", 34 SPACOM 2 EN1.
