5.2.8 Output relays (control outputs)
Depending on instrument type, the PQC is equipped with 6 or 12 output relays (con-
trol outputs). Relays or contactors are usually connected to these to switch the capac-
itor stages in and out.
The output relays Q1–Q12 (Q1–Q6 in the case of PQC versions with 6 output relays)
receive their control voltage from a common feed P. The load ratings of the output
relays and the common feed line P can be found in the connection diagrams or the
technical data (see Section 3 “Technical data”).
If not all of the available output relays are to be used, it is recommended to connect
the output cables starting with output 1 and leaving no gaps.
5.2.9 Alarm function
The PQC has a volt-free contact to transmit alarms externally, alarm terminals a and b
being provided for this external connection as shown in the diagrams in Section 5.2.10
“Connection diagrams for all PQC types”. Attention must be paid to the load rating of
the contact (see Section 3 “Technical data”).
