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
"chapter stepsize detection / defective capacitors
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.
