TAP-UP COMMAND
This signal becomes active when the DTR receives by communications a command to increase the tap in the OLTC.
TAP-DOWN COMMAND
This signal becomes active when the DTR receives by communication a command to decrease the tap in the OLTC.
-E-1, -E-2, ..., -E-35
This signals indicate the status (active or not active) of the physical inputs of the DTR. This signals can be used to do
logic circuits (OR, AND) using external and internal signals by means of the GE_INTRO configuration software.
STOPPED, AUTOMATIC, MANUAL, TIMING, TAP-UP PULSE, TAP-UP TIME, TAP-UP=SUCCES, TAP-UP=FAIL,
TAP-DOWN PULSE, TAP-DOWN TIME, TAP-DOWN =SUCCES, TAP-DOWN=FAIL.
These signals represent the status of the regulation automatism.
REM TRIP PULSE.
This signal indicates the status associated to Remote Trip
HOLD REM TRIP.
This intermediate signal is enabled to permit the activation of the REMOTE TRIP INPUT by pulse, and not by level.
-E LOCAL
This signal becomes active when the DTR system receives in a digital input (RTU) a signal to change the DTR to
local mode.
-E REMOTE
This signal becomes active when the DTR system receives in a digital input (RTU) a signal to change the DTR to
remote mode.
-E TRIP. REM.
This signal indicates that the unit has received through an input a command to permit the operation of an associated
output contact, independently from the operation mode.
-E STOP
This signal becomes active when the DTR system receives in a digital input (RTU) a signal to stop the regulation
automatism.
-E AUTOMATIC
This signal becomes active when the DTR system receives in a digital input (RTU) a signal to change the regulation
automatism to AUTOMATIC mode.
-E MANUAL
