BLR-CX
ATTENTION!
When installing BLR-CX, there are the dangers of electric shock! Installation and
commissioning are therefore to be performed by a technician with necessary
qualification. During installation, the relevant regulations setting up of switchboards
and accident prevention have to be respected.
Equipment with damaged or open housing or terminals shall not be operated at
mains and are instantly to unlock.

Installation and Commissioning:
1) Compare voltage and current ratings of BLR-CX with data of mains
and installation!
2) Disconnect panel from mains voltage (5 safety rules of electricity!)
3) Is CT short-linked or not in operation?
High voltage level of an open secondary of CT endangers people
and devices. The CT will be damaged by this.
4) Disconnect and remove previous pfc-relay..
5) Mount BLR-CX to the control panel with two mounting clips.
(cutout 138x138mm)
6) Connect protection earth to PE connection of metal case.
7) Connect BLR-CX according to connection diagram.
(CT/P1 income-feeder, CT/P2 load!)
8) Remove short-link from CT
9) Connect mains voltage to panel.
10) When connection of relay is correct and technical data of mains is
according to ratings and settings of BLR-CX, LCD will show AUTO
and control function will start!

FAQ during Commissioning:
1) No indication AUTO PFC is stopped
Cause: manual operation, SETUP/100/PFC = OFF or HOLD,
temperature is too high, current < 15mA, voltage oder THD U is out
of tolarance.
2) Indication U ALARM "voltage out of tolerance
Check settings for nominal voltage (SETUP/Un) and
voltage transformer (SETUP/Pt)
3) Indication I Lo ALARM "current < 15mA
Cause: connection error of CT; short-link of CT is not removed; CT-
ration is too big compared to real current; no current
4) Indication EXPORT "kW export
if there is no real kW export, voltage and current connection of BLR-
CX has to be checked! "chapter wrong connection
5) Wrong Cos jindication "wrong connection
voltage and current connection of BLR-CX has to be checked!
"chapter wrong connection
6) Exits are connected and immediately disconnected

7) Frequent switching operations
size of capacitors is not completely detected

INFO Step Database:
Attention: Actual state of control outputs is not shown!
Choose step by p, qand enter by u. The selected step is blinking. By
using p, qfollowing information can be selected:
Actual Size of Capacitor
the value is rated to nominal voltage
Derating of Capacitor:
actual power / nominal power in %
Switch Cycles:
Steptype:
AUTO: automatic controlled step
Fon: step fix on
Foff: step fix off
AL: step used for fan control
FLty: defective step

MANUAL Operation:
For manual operation uhas to be pushed for 3 seconds!
Selection of step by p, q. Number of selected step is shown in line 2 of
LCD. By pushing uselected step will switch on / off..
Manual operation will be left by t.
Important Information:
- Menue Manual Operation cannot be opend in modes LIFO and
Combi-Filter. ("Referencebook!)
- Discharging lock-time is also active during manual operation
(steps are locked a certain time after switching-off)
- when voltage is out of tolerance all steps are disconnected.
- THD U-alarm and overtemperature are locking switching-in steps in
manual operation.
- Only steps with steptype AUTO can be switched!
- After leaving manual operation menue, control continues from
actual state.

Wrong Connection / AI - Automatic Initialising:
A pfc-relay needs a correct connection of voltage and current (polarity and
phase), for a proper function. If this is not the case, connection must be
corrected. As this is not always possible, BLR-CX is offering alternativly the
following functions:
Manual Correction: SETUP / 200
Automatic Initialising: SETUP/ 100 / Ai
Ai is connecting and disconnecting all control exits several times on and
off. Duration for this is several minutes! Not connected exits get steptype
Foff. Stepsizes are not detected by this function!
After finished Ai, BLR-CX has to be checked for correct function!
Requirements for successful operation of Ai:
- voltage is within tolerance
- CT is conencted (no simulation!)
- capacitor banks are installed and fuses are insert
Possible problems for function of Ai:
- load variations
- small current signals (big CT-ratio, small stepsizes)
Failure indication Ai / Abrt:
Ai is abort, as no clear result could be achieved,PFC = OFF.
"Referencebook

Step Size Detection:
At each switching operation, step size is measured (except this function
is not active SETUP / 300 "Referencebook)
Because of this setting of c/k value is not necessary. Switching sequence
is defined automatically by using the selectied capacitors.
The recognised values are taken to stepdatabase. A derating of
capacitors can be seen there.
Is there no function of a step during the first 3 switching operations after
a reset of stepdatabase, steptype Foff is set automatically.
Defective Steps:
When a step is switched 3 times in series without measured size, it is
detected as defective and it is blocked for 24h.
Step state: blinking
Status: Flty, step is blocked
Failure analysis:
After commissioning, all steps have step type Foff:
Is short link of CT secondary removed?
Is position of CT correct?
Are all fuses present and in order?
In normal operation, one or more steps are blinking?
How is condition of fuses, contactors and capacitors of this step.
Reset in SETUP / 100 / OUt or by re-start (interruption of supply
voltage) of BLR-CX!
