1 Instruction 1.1 Introduction Before connecting the regulator to the mains, read the instructions in this handbook, they provide important indications about the safety, use and maintenance. Take carefully this handbook for any information. This regulator has been manufactured and tested in accordance with international standard, it leaves the factory in perfect safety conditions. In order to mantain these condition and to ensure safe operation, the user must comply with the instructions and remarks given in this manual. After removing the packaging check that the regulator has not been...

1.2 Operator safety Before to perform any maintenance, the regulator must be disconnected from any power supply source, wait 5 minutes before start any action. During maintenance it is necessary to follow standard safety procedures. Do not touch any printed circuit board for any reason. This regulator will be assigned only to the use for which it has been specifically made. Each other use has to be considered improper and therefore dangerous. 1.3 Instruction for proper installation Before connect the equipment, check the data plate: this has to be in conformity with the electrical network...

24 1.5 Warranty Comar Condensatori S.p.A. guarantees its own products for twelve months from purchase date. The warranty covers the faults of materials and manufacture and it has to be understand for goods ex-works. Before the equipment works, all instructions, present on this handbook, have to be meticulously followed. Breakdowns caused from improper use and/or not conformity to enclosed instructions and faults caused from tampering by unqualified technicians aren’t covered. The misuse of any of the previous points will erode the right of warranty. 2 General 2.1 Unit description QSR is an...

25 2.3 Worning situation The regulator works according to binary logic sequence; the switching on and off of capacitors banks always start from the first bank. 2.4 Power of controlled banks For correct operation of the automatic bank, the power ratio per bank should be: a. equal to each other (1-1-1-1-1-1-1-1) b. double of the previous bank (1-2-4-8-16-32) c. equal or double of the previous bank (1-1-2-2-4-4) 2.5 Number of steps Is determined by the power combination which has been used on single capacitors bank: Examples: 6 banks in the sequence 1-1-1-1-1-1 make 6 steps 6 banks in the...

3.5 How to choose the CURRENT TRANSFORMER (C.T.) Use a Current Transformer (C.T.) with 5A at secondary circuit and primary equal or slightly higher than the maximum absorbed by the loads. The C.T. must be chosen in such a way to obtain a good current signal in the secondary circuit. Current values between 0.5 and 5Amps are suitable to obtain good working conditions of the regulator. The C.T. must be good quality (first class) and with power equal or higher to 5VA. If the C.T. has been mounted far from the equipment, it needs to add the normal demanded the power consumed from the cables of...

31 The C.T. has to be connected to the line, upstream the load and the P.F. Regulator: the C.T., can then measure the current demanded by the load, inductive and capacitive. Possible capacitors for fixed P.F.Regulation will be mounted downstream of the C.T., as they aren’t used and dimensioned for the P.F. Regulation of transformers that feed the load. It’s important to check that the phase, where the C.T. is connected, is the same that will be connected to terminals of the main switch, inside the equipment, signed with the letter “L1”. Before doing any work on the C.T. circuit, be sure...

4 Functions 4.1 Powering on When power is switched on, an internal self test routine has been performed. The display shows the installed s/w release. Power Factor Regulator 4" Setup Made in Europe SELF TEST - v1.9 After start-up process, the regulator is working in ”Automatic” operation. 4.2 Key function The key enable change from “Automatic” to “Manual” (light is on). When pressed for 4 seconds it enable to enter the set-up page and confirm setting Keys used in “Manual” enable switch-on and off the output. Used in “SET-UP” enable setting of the value. Used in “Automatic” enable...
