DKG-108 User Manual V-1.0
(10.08.2011)
-15-
The unit constantly monitors abnormal situations occurring in the system.
Every monitored parameter has programmable alarm limits and delay timer. Alarms may be
of latching or unlatching types. The automatic operation may be programmed to be aborted
or continued. For more details please consider the PROGRAMMING section of this
manual.
When any alarm occurs the ALARM led turns on and the alarm code appears on the
display. Following programming, the auxiliary relay output may be activated. The automatic
operation may be aborted or continued, based on programming.
AL-01: NETWORK NOT 3 PHASED
Occurs if automatic setup is attempted
with non 3 phased network.
AL-02:FIRST BANK NOT 3 PHASED
Occurs if automatic setup is attempted
with non 3 phased capacitors at the fist
bank.
AL-03:FAULTY CT ORDER
Occurs if automatic setup is attempted
with CTs not connected to related phases.
AL-04:HIGH VOLTAGE
Occurs if at least 1 phase voltage is
above
u-Hi
limit during
u-dU
period.
AL-05: LOW VOLTAGE
Occurs if at least 1 phase voltage is below
u-Lo
limit during
u-dU
period.
AL-06: HIGH FREQUENCY
Occurs if the frequency is above
F-Hi
limit
during
F-dU
period.
AL-07: LOW FREQUENCY
Occurs if the frequency is below
F-Lo
limit
during
F-dU
period.
AL-08:EXCESS kW
Occurs if the total active power is above
A-Hi
limit during
A-dU
period.
AL-09: LOW kW
Occurs if the total active power is below
A-Lo
limit during
A-dU
period.
AL-10:EXCESS INDUCTIVE kVAr
Occurs if the total reactive power is
inductive and above
rInd
limit during
r-dU
period.
AL-11: EXCESS CAPACITIVE kVAr
Occurs if the total reactive power is
capacitive and above
rCAP
limit during
r-
dU
period. (Welded contactors)
AL-12:
INDUCTIVE CosØ
Occurs if the total cosø is inductive and
below
cInd
limit during
C-dU
period.
AL-13:
CAPACITIVE CosØ
Occurs if the total cosø is capacitive and
below
cCAP
limit during
C-dU
period.
(Welded contactors)
AL-14: EXCESS CURRENT
Occurs if at least 1 phase current is above
CrHi
limit during
CrdU
period.
AL-15:EXCESS THD(V)
Occurs if at least 1 phase voltage THD is
above
thdu
limit during
uhdU
period.
AL-16:EXCESS THD(I)
Occurs if at least 1 phase current THD is
above
thdi
limit during
chdU
period.
rAt1...rAt8 CAPACITORVALUE LOSS
Occurs when the measured step rating is
below
rtio
% compared to its nominal
value. In order to enable this alarm
dYnC
parameter must be
1
.
AL-18:PHASE ORDER FAULT
Occurs if the voltage phase order is faulty.
Err1...Err8: CAPACITOR DEFECTIVE
Occurs when the measured capacitor
rating is below 20% of its nominal value.
