186 Tap position analog
output
The value cannot be output via
the analog output. Check the parameter settings and the wiring of
the analog output.
259 Phase sequence incor-
rectly connected
Phase sequence incorrectly con-
nected Check whether the motor is correctly connected
to the power supply (note rotary field!).
260 Limit value ∆U-3ph The limit value for the difference
in voltage between the three
phases is exceeded. Check the current operating conditions of the
transformer and the set parameter ∆U-3ph.
263 Limit value ∆f-3ph The limit value for the angle dif-
ference between the three
phases is exceeded. Check the current operating conditions of the
transformer and the set parameter ∆f-3ph.
266 Measuring connection
or configuration faulty
The connection and/or configura-
tion of the three-phase measure-
ment is faulty. Inspect the connection of the current trans-
former and voltage transformer and the configu-
ration of the three-phase measurement.
267 cosf interpolation ac-
tive
The parallel operation is carried
out with interpolated values. No CAN bus communication with other
TAPCON® present. Check wiring as per con-
nection diagram.
271 Signal from gear motor
missing
No feedback from gear motor
(S13) Ensure that the gear motor is correctly con-
nected to the control cabinet. Check the func-
tionality of the cam switch S13.
276 Protective relay RS of
OLTC column A trig-
gered
The protective relay RS of the on-
load tap-changer (column A) has
triggered. Contact Maschinenfabrik Reinhausen GmbH's
Technical Service department.
279 Pressure relief device
of OLTC column A trig-
gered
The pressure relief device of the
on-load tap-changer (column A)
has triggered. Contact Maschinenfabrik Reinhausen GmbH's
Technical Service department.
282 Pressure relief device
of transformer trig-
gered
The pressure relief device of the
transformer has triggered Establish the cause of the pressure relief device
triggering.
283 Buchholz relay: Accu-
mulation of gases (col-
umn A)
The Buchholz relay of the on-load
tap-changer (column A) is report-
ing the accumulation of gases. Establish the cause of gases accumulating.
286 Buchholz relay: Loss of
insulating fluid (column
A)
The Buchholz relay of the on-load
tap-changer (column A) is report-
ing a loss of insulation fluid. Establish the cause of the loss of insulating
fluid.
289 Buchholz relay: Insu-
lating fluid surge (col-
umn A)
The Buchholz relay of the on-load
tap-changer (column A) is report-
ing a sudden surge in insulating
fluid. Establish the cause of the surge in insulating
fluid.
292 Buchholz relay: Accu-
mulation of gases
(transformer)
The Buchholz relay of the trans-
former is reporting the accumula-
tion of gases. Establish the cause of gases accumulating.
293 Buchholz relay: Loss of
insulating fluid (trans-
former)
The Buchholz relay of transformer
is reporting a loss of insulation
fluid. Establish the cause of the loss of insulating
fluid.
294 Buchholz relay: Insu-
lating fluid surge
(transformer)
The Buchholz relay of the trans-
former is reporting a sudden
surge in insulating fluid. Establish the cause of the surge in insulating
fluid.
