- Page 6 Section 2 Installation and connection of the controller The BR 604 is designed to be incorporated into the front panel of a PFC- cabinet. It requires a switchboard section of 92 x 92 mm to DIN 43 700. The controller is inserted from the front and is attached by means of the appended clamps.

Page 7: Current Measurement
The outputs of the compensation network must be installed behind the current converter (in the direction of current flow). If the BR 604 is connected up via sum- current converters, the overall conversion ratio is entered. -
Page 8: Fault Messages
MEASURING CURRENT < Section 3 Operating modes and programming When the operating voltage is switched on, the BR 604 briefly displays its designation and software version, then changes to its normal operating status (automatic operation). The active cos-phi value is always displayed in the upper line and the currently connected capacitors are shown as symbols in the lower line (operating display). -
Page 9: Automatic Operation / Display Functions
Manual (manual operation)- Service - Expert mode and back. 3.1 Automatic operation - display functions The BR 604 is set to automatic operation as standard. Capacitor stages are then automatically connected in or out in order to reach the target power factor. - Page 10 LANGUAGE SELECTION: This selects the language of the operating menu ( English, German, Spanish, Portuguese) ) 1 I-CONVERTER PRIM: This selects the primary current of the current converter. Adjustment is via the é / ê keys. (5...7500A) Save and continue with ENTER 2 I-CONVERTER SEC: This sets the secondary current of the current converter.(5A or 1A possible).
- Page 11 7 TARGET COS PHI: By setting the target cos phi, the power factor to be attained via the PF correction is defined. It is also set via the é / ê keys. The range may be selected from 0.3 inductive to 0.3 capacitive.

Page 12: Programming Lock
3.3 Programming lock The BR 604 is equipped with a programming lock to ensure protection from unauthorized or inadvertent changes to the system parameters. The lock can be activated in expert mode. If the lock is active, all parameters can be checked but not changed. -

Page 16: Control Principle
Section 8 Control principle The control response of the BR 604 can be selected in programming mode. In principle, the controller has 3 different control modes: 1. Sequential connection In sequential connection, the required capacitor stages are successively connected and disconnected in stages (last in - first out). -

Page 18: Maintenance And Warranty
Section 10 Maintenance and warranty The BR 604 should need no maintenance if the operating conditions are observed. However, it is recommended that a functional check of the controller be performed in conjunction with the regular checking of the capacitor bank. In the event of any interventions in the controller during the warranty period, all warranty claims lapse. -
