7.2 General faults

Fault display

Cause

Display remains blank.

- supply voltage is missing.
- equipment fuse is defective. Possibly the applied supply voltage is too high.

Controller does not react to changes; display shows actual cos 

ϕ

and LED 

'

AUTO

' 

flashes.

- Controller has been changed to '

MAN

', press key           to revert to automatic

operation.

Controller is hunting.

- C/k value is too low (only with 

AU3

 mode)

Controller displays a capacitive power factor while inductive

load is present, and no capacitor steps are switched in.

- C.T. connection 

k/l

 

(S1/S2) 

is mixed up (only with 

AU3

 mode)

The set target power factor is reached but does not coincide with

the actual power factor of the plant.

- a wrong measuring voltage connection is set in mode 

AU2

 

or 

AU3

.

The displayed current does not coincide with the actual current.

- the current transformers connected to the summation current transformer are

wrongly 'poled'.Terminals 

k/l (S1/S2)

 

are mixed up, i.e. the currents are not added

up but subtracted.

-

 

the current measuring path of the Controller is connected in parallel with other
measuring equipment; current measuring paths should be connected in series.

- A wrong setting of the C.T. transformation ratio k (parameter 18) was made.

Upon switching it in, the Controller starts with initialization

mode 

AU2

 and, after this mode is completed, operates

incorrectly.

- Controller is set to 

AU1 

and uses wrongly memorized data. Possibly the Controller

had been applied in another plant before, wiring of measuring connections were
changed, or a fault occurred with mode 

AU1

.

- refer to items 6.0 and 6.3 'setting menu' in order to select  the initialization mode

new.
