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.
All 32 O/P channels of the second 216AB61 unit in a system are available for the signals of active protection functions.
the front view of the binary O/P unit, which is a plug-in unit with a width of 1 standard division (1T). The internal auxiliary supply voltage is 5 V and is derived inside the unit from the 24 V auxiliary d.c. supply. The unit's main components are:
a bus interface
an O/P register and O/P monitor
O/P driver stages.
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.
