Page 4: 1．Introduction
JB/T 9663－1999 Low-voltage reactive power automatic compensation controller 1.2 Overview SFR-M series low voltage intelligent power capacitor modules take two △ type compensation capacitors or one Y type compensation capacitor as main body and are highly integrated with compound switch, microprocessor and other function modules. Due to their modularity structure, they have such advantages as small volume and easy maintenance. -

4.3.3 Secondary Current Transformer is an optional unit which is used for primary current (5A) sampling in bus line of incoming cabinet. The transformer is necessary when customer only use SFR-M series low voltage harmonic suppression reactive compensation module. Usually SFR-M series modules are defaulted to be equipped with reactive power compensation controller （... - Page 8 WGK-31-203-G compensation controller is suitable, otherwise, please equip WGK-31-203-F compensation controller in that system. SFR-M series modules are connected with WGK-31-203 compensation controller by specialized pluggable data line. One WGK-31-203 controller can be connected up to 32 SFR-M series modules.

（3） The following operation process shows an example for module switching parameters (Usually it is not needed to set these parameters only if there is no controller.) 6. Panel description and measurement information display... - Page 12 1. C1 and C2 indication lights show the switching and running status of two capacitor modules; if Fault indication light is on, that means the power capacitor module is in protection status. 2. Three-row code segment LCD shows measured electrical information such as present status of power capacitor module, capacity, temperature and electrical parameters.

automatically; Er 06： Three phase unbalance protection, need to be reset; Er 07： Harmonic voltage protection THDu%, return to normal automatically; Er 08： Harmonic current protection THDi%, return to normal automatically; Er 09：Internal fault, need to be reset. 7. Common problems and solutions 7.1 Automatic switch in after power on The compound switch inside a module is defaulted to be open, but it may become closed because of vibration in transportation. -

in; if the indication light is off, that means the capacitor module is switched off. ② Controller normal switching test 1) Change the dial switch on the capacitor module to Work; 8.Change the power factor of circuit. Controller will control the real switching of capacitor modules according to power factor.
