3ASC25H209 DATX110 ABB Control unit new automatic controller module

Description

The position of the plug-in jumper XJ1 on the PCB determines
whether the unit’s system alarm signals (“System defect” and
“Stand-by” signals CHO01, CHO02) are operational or not. They
must be in operation in the first O/P unit of a system.

1st 216AB61 (at rack division 12): XJ1 in position X4-X5

2nd 216AB61 (at rack division 13): XJ1 in position X3-X4
The signalling channels are assigned to the activated protection
functions (configuration) with the aid of the portable user interface (PC) connected to the 216VC62a unit.
Refer to the set of specific plant diagrams for the configuration of
the particular plant.
2.5.5. Analogue/binary O/P unit 216AC61
O/P unit 216AC61 has 8 analogue and 16 binary O/P channels.
The analogue O/P’s supply impressed currents in the range 0 –
20 mA, e.g. for driving instruments. They are thus used for
displaying the variables measured by protection functions or an
SCS. The analogue and binary O/P channels are neither
electrically insulated from each other nor from the auxiliary
supply.
The binary O/P signals generated by the active protection functions (protection and control) can be transferred to the auxiliary
relays K1…K16 in the O/P relay unit 216GA61 for purposes of
remote signalling.

connector “a” (upper) : binary channels CHO01…CHO16

connector “b” (lower) : analogue channels AA001…AA008
Where a system requires several 216AB61 and/or 216AC61
units, the O/P channels are designated within the system according to Table 2.1.
If the system does not include a 216AB61 unit, the binary O/P
channels CHO01 and CHO02 of the first 216AC61 unit (at rack
division 12; see Fig. 2.2) are used for the system alarms (the unit
can thus be used instead of a 216AB61).

CHO01 : Stand-by (general alarm line SML); active during
normal fault-free operation.

CHO02 : No system defect (stand-by signal line CK); active
during normal operation.
