Sistema Qualità Certificato BELTRAME CSE, TEL. 049/5965127 - FAX 049/9440024 - MAIL TO: info@beltramecse.com PICTURE OF THE REACTIVE POWER SHARER S155 Vn 100/220/400 V 50/60 Hz TECHNICAL DESCRIPTION THE FACTORY CAN MAKE MODIFICATIONS AND IMPROVEMENTS WITHOUT ANY PRIOR NOTIFICATION REGISTERED MODEL The module S155 is a reactive power sharer especially designed for paralleling systems, and his high performances are the result of more than 25 years experience in regulation of power production plants. This device is very simple to use: adjusting a trimmer, the DROOP is controlled within a range of 0-10% . An output terminal, ranging from 0,5V makes the S155 suitable for connection to others devices by Beltrame c.s.e; for example the AVR S099, S130, S160, please see below. In this way, three different combination of regulation are possible using the same S155. Moreover, the S155 keeps under control the reactive power for each generator in parallel using the same DROOP. ADJUSTMENT PROCEDURE FOR S155 The S155 has a few dip switch to set the parameters. - Dip switch 1 in off position sets the maximum current detectable by the T.A to 1Amp. - Dip switch 1 in on position sets the maximum current detectable by the T.A. to 5Amps. - Dip switch 2 is not qualified. - Dip switch 3 in on position enables to check the DROOP. - Dip switch 4 is always pre-set in off position. - Dip switch 5 in off position enables to check the maximum current I max. - Dip switch 5 in on position enables to control trimmer number P3, which is pre-set by the manufacturer and can not be changed by the customer. - Dip switch 6 in off position gets the device work in 50 Hz mode. - Dip switch 6 in on position gets the device work in 60 Hz mode. The DROOP is regulated with trimmer P1. During the first running test this trimmer must be completely turned counterclock- wise to get the minimum value of the DROOP itself. Turning trimmer P2 it is possible to select the work range of T.A. (for example, if T.A is 100A and the load is 80 A the minimum value will be set moving P2 trimmer to 80A). STANDARD FEATURES OF S155 Each S155 is delivered to the customer having the following pre-set standard configuration: - Dip switch 1 in on position so to have the T.A. current reading value set to 5A - Dip switch 3 in on position so that the DROOP can be controlled turning the trimmer P1 - Dip switch 5 in on position so that control goes by turning trimmer P3 (this can not be changed). FUNCTIONING OF S155 L2 and L3 are two voltage inputs, whereas TAs2 and TAs1 is the current input; these determines the output voltage 0¸5V and get the desired reactive power just turning the trimmer P1. The module S155 is available with three different feeding: 100V, 230V, 400V. So the following are available: S155/100, S155/230, S155/400. The standard version is S155/400. CONNECTING S155 WITH AN AUTOMATIC VOLTAGE REGULATOR Use the red & black cable of the S155 to connect with input IN S155/PFC of the AVR (S130 or others). Use terminal L2 to connect with the phase output L2 of the alternator, and use terminal L3 to connect with the phase output L3 of the alternator. Finally connect terminal Tas2 of S155 with P2-S2 of the T.A., and connect terminal TAs1 of S155 with P1-s1 of the T.A. made in Italy
