Reactive Power Controller; Start-Up And Operation - Icar MICROmatic HP10 Manuel D'installation Et D'opération

Before putting the power factor correction cabinet into service, it is essential to close all openings
machined for cable entry by means of suitably shaped plates.
Total removal of the cable entry plates, whether on the top or bottom of the cabinet, could cause
damage to the unit by ingress of foreign matter inside it, besides impairing correct operation of the
forced ventilation system.

5. REACTIVE POWER CONTROLLER

The type of automatic controller mounted can vary according to the required specification. Hence as regards its
characteristics and
calibration procedures, consult the specific instructions which are always attached to the unit.

6. START-UP AND OPERATION

After carrying out the operations described in the section "Connections to mains", the unit is ready to be
switched on.
Before powering up the unit, check for correct tightening of all connections.
After closing the main disconnect switch Q1 (see Attachment C/D), preset the primary value on the current
transformer connected to the
controller (for presetting of this parameter, see "Quick guide for putting the unit into operation").
To check for correct operation of the unit in manual mode, switch the controller to "MANUAL" function, then
insert the single steps checking that they draw the correct amount of current.
When the controller is turned to "AUTOMATIC" mode, the unit switches the various capacitor banks in and out
depending on the load demand; in this case, the number of banks switched in is signalled by the lighting up of
the STEP leds located on the reactive power controller.
- If optional control and protection module MCP4 is installed (see Attachment C); for functions and
characteristics, refer to the specific instructions always attached to the cabinet.
- If reactive power controllers RPC 5LSA, RPC 5LGA, RPC 8LGA, RPC 7LSA, RPC 8BSA, RPC 12BSA, RPA
8BMA, RPA 12BMA, RPE 12BTA and RPC 8BGA are installed, the starting and stopping of the fan are
controlled directly by the controller (if module MCP4 is not installed).
These latest generation controllers are also able to check for any thermal overloading; hence they can switch
out all steps enabled thereby generating an alarm on the display.
CAUTION!
CAUTION!
Periodically repeat such operation.
