ICAR PQS rev8 may1835 / 86For each alarm, it is possible to define:o the source that is the condition that generates the alarm,o the text of the message that must appear on the screen when this condition is met.o The properties of the alarm (just like for standard alarms), that is in which way that alarms interacts with the powerfactor correction.The condition that generates the alarm can be, for instance, the overcoming of a threshold. In this case, the source will be one ofthe limit thresholds LIMx.If instead, the alarm must be displayed depending on the status of an external digital input, then the source will be an INPx.For every alarm, the user can define a free message that will appear on the alarm page.The properties of the user alarms can be defined in the same way as the normal alarms. You can choose whether a certain alarmwill disconnect the steps, close the global alarm output, etc. See chapter 21.2 Alarm properties.When several alarms are active at the same time, they are displayed sequentially, and their total number is shown on the statusbar.To reset one alarm that has been programmed with latch, use the dedicated command in the commands menu.For details on alarm programming and definition, refer to setup menu M2616 MASTER-SLAVE CONFIGURATIONTo further extend the flexibility of use of 8BGA power factor controller it is available the Master-Slave function, which allows, forplants with high installed power, to compose a series of panels in cascade, each with its own controller and associated capacitorbanks.This solution allows to expand in a modular way the power factor correction system, in case it becomes necessary because of theincreased needs of the plant.In this configuration, measurements are made only from the first controller (Master) which controls a maximum of 32 logical stepswith commands that are then sent to all the slave units.The slave controllers drive their steps as indicated by the master, while performing the ‘local’ protections like panel or capacitorovertemperature, no-voltage release, harmonic protections etc.The maximum possible configuration is one master with 8 slaves.Example 1 (application in series):It is required to create a system with 18 step of 40kvar each, divided into three identical panels with 6 step (240kvar) each. Foreach panel, the 8 relay outputs of the controller are used as follows: the first six for the steps (OUT1. .6), the seventh for thecooling fan (OUT7) and the last for the alarm (OUT8). On the master panel we will define 18 logical step of 50kvar. The stepsfrom 1 to 6 will be 'mapped' on the outputs OUT1 .. 6 of the master, those from 7 to 12 on the outputs OUT1 .. 6 of slave1 andfinally the steps from 13 to 18 on the outputs OUT1 .. 6 of the slave 2. In this case, the parameter P02.07 Smallest step powerwill have to be set (on the master) to 40kvar.Programming of the master:PARAMETER VALUE DESCRIPTIONP02.07 40 40 kvarP03.01.01…P03.18.01 1 All the 18 logic steps are 40kvarP04.01.01…P04.06.01 Step 1…6 Outputs OUT1…OUT6 of the master are activated by logical steps 1…6.P04.07101 Fan OUT7 of the master controls the ventilation systemP04.08.01 All glb 1 OUT8 of the master controls global alarm 1P05.01 COM1 COM port used for the linkP05.02 Master Role of masterP05.03…P05.04 ON Enables slave 1 and slave 2P06.01.01…P06.06.01 Step 7…12 Outputs OUT1…OUT6 of slave 1 are activated by logical steps 7…12.P06.07.01 Fan OUT7 of slave 1 controls the ventilation systemP06.08.01 All glb 1 OUT8 of slave 1 controls global alarm 1P07.01.01…P07.06.01 Step 13…18 Outputs OUT1…OUT6 of slave 2 are activated by logical steps 13…18.P07.07.01 Fan OUT7 of slave 2 controls the ventilation systemP07.08.01 All glb 1 OUT8 of slave 2 controls global alarm 1Programming of slave 1:P05.02 Slave1 Role: slave1Programming of slave 2:P05.02 Slave2 Role: slave2Example 2 (application in parallel):A system provides 8 logical step for 400 kvar total. The system is organized on two panels. Each panel has 8 steps of 25 kvar.The logical step are programmed as 8 banks of 50 kvar. The first step is ‘mapped’ on OUT1 both for the master and for slave1,same for step 2 mapped on OUT2 on the master and the slave, and so on. When step1 is activated, it will result in the activationof both the first bank of the master board (25kvar) and the first bank of the slave1 (25 kvar) for a total of 50kvar. In this case theparameter P02.07 Smallest step power must be set (on the master) at the resulting value of 50kvar.
