VME-5565 Gas turbine electrical module

An RE. 216 system can have a maximum of two 216EA61 units with a total of 48 I/P's. Every input can be used by any number of protection functions. The type of every channel must be defined:
Voltages:
single-phase
three-phase delta-connected
three-phase Y-connected
Currents:
single-phase metering
single-phase protection
three-phase metering
three-phase protection. All protection function settings are based on the input values (secondary ratings) of the RE. 216. The fine adjustment to suit the effective primary system quantities is accomplished by varying the reference settings of the c.t/v.t inputs (see "Setting the c.t/v.t inputs"). Three-phase I/P's must be wired consecutively to adjacent I/P channels. The first channel (R phase) must thus be connected to either channel 1, 4 or 7 etc. Since c.t/v.t I/P's are scanned simultaneously in groups of 6 channels, associated channels should be in the same group wherever possible (e.g. channels 1 to 6, 7 to 12 etc.). The following applies with respect to the allocation of c.t/v.t inputs to protection functions:
Generally, only the first I/P (R phase) of three-phase I/P's is stated.
In the case of functions with several c.t/v.t inputs, all I/P's must be processed by the same 216EA61 unit.
For certain functions, all the c.t/v.t inputs must belong to the same scanning group (e.g. generator differential protection). For others (e.g. power) the I/P's must belong to the same scanning group to achieve maximum sensitivity

Binary inputs (binary addresses)

 In a RE. 216 scheme, a binary signal can have one of the following values:
logical "0" (fixed value) = FALSE
logical "1" (fixed value) = TRUE
binary input values (216DB61, 216EB61)
Double indication signals; two consecutive binary inputs are combined.
binary protection values (trips) as defined by the function number and the corresponding signalling output. All the above can also be set as binary inputs of protection functions. All the binary addresses set may be used either directly or inverted. 3.2.3. Signalling outputs (signal addresses) All the RE. 216 signalling outputs (signal addresses) can be configured for one of the following modes of operation: 1) Control a signalling relay and be recorded as an event.

Pick-up signals activate "General start" (signal and event)
Tripping signals activate "General trip" (signal and event)
