output to be deasserted, its input must be deasserted for the dropout time. If an I/O board is
installed, you may define conditions that assert outputs on the board.
You define the logic elements using SEL
OGIC
Control Equations and set their timers using the
SET G command. For a complete discussion of these equations, see Section 7: SEL
OGIC
Control Equations.
Table 6.18 includes a complete description of the SET G settings.

Setting Comment
ID Prompt . Device Identification.
Description . Any string of up to 40 characters that you wish to use to identify this device.
TIME_SRC Prompt . SEL-2020 Time Synchronization source (IRIG, DNP, OFF).
Description . Select the source used by the SEL-2020 to time-synchronize itself.
LOG_EN Prompt . Enable use of intermediate logic (Y/N).
Description . There are five intermediate logic variables, three of which have associated
timers. You set this setting to Y (Yes) to enable their use, or set it to N (No) if you do not
plan to use them.
V Prompt . V=.
Description . You enter a SEL
OGIC
Control Equation definition for the intermediate logic
element V.
W Prompt . W=.
Description . You enter a SEL
OGIC
Control Equation definition for the intermediate logic
element W.
X Prompt . X=.
Description . You enter a SEL
OGIC
Control Equation definition for the intermediate logic
element X.
Y Prompt . Y=.
Description . You enter a SEL
OGIC
Control Equation definition for the intermediate logic
element Y.
Z Prompt . Z=.
Description . You enter a SEL
OGIC
Control Equation definition for the intermediate logic
element Z.
