The connections are similar in all SESRSYN functions, apart from the breaker
position indications. The physical analog connections of voltages and the
connection to the IED and SESRSYN function blocks must be carefully checked in
PCM600. In all SESRSYN functions the connections and configurations must
abide by the following rules: Normally apparatus position is connected with
contacts showing both open (b-type) and closed positions (a-type).
