new product 2014 • Synch check relay • Front panel conﬁgurable • 50/60 Hz comptability • Basic unit ASSOCIATED PRODUCTS Advanced: C2S Complementary: UNIGEN Family SCR2.0 Synchroscope/Synch check relay SCR2.0 is a microprocessor controlled synchroscope with programmable synch check relay in a DIN96 front panel mounted package. It monitors the voltage and frequency of 2 independent power sources as well as the instantaneous phase angle between them. The measured parameters are displayed on the 3 digit display and the 24 led circular synchroscope displays the phase angle between the 2 power source. The synchroscope display is only activated if both power source voltages are within the set limits. A SIMPLE PRODUCT FOR SAFETY FUNCTIONS Synchronization checking is enabled either via the SYNCH CHECK ENABLE signal input or by pressing the front panel SYNCH pushbutton. If all the necessary conditions are satisﬁed: • busbar phase (busbar phase voltage) voltage between set limits • generator phase voltage between set limits • busbar-generator frequency diﬀerence below the set limit • busbar-generator voltage diﬀerence below the set limit • busbar-generator phase diﬀerence (phase diﬀerence below) below the set limit The SYNCH CHECK relay will be energized. If the busbar is not powered up, the synch checking may be overridden with the DEAD BUS ENABLE signal input. FRONT PANEL CONFIGURATION SCR2.0 provides a comprehensive set of digitally adjustable threshold and timers. All settings are modiﬁed via front panel pushbuttons, and do not require an external unit. The MENU pushbutton allows the digital display to navigate between various measured parameters. SCR2.0 is dedicated to basic applications which require no extra costs or expensive hardware. All CRE TECHNOLOGY products aim to provide the same satisfaction levels. The SCR2.0 has passed EMC and low voltage tests, and each unit is 100% tested before delivery. RELAY OUTPUTS The unit provides a synch check relay output with voltage free
