THE ENGINE, TURBINE, OR OTHER TYPE OF PRIME MOVER SHOULD BE EQUIPPED WITH AN OVER SPEED (OVER TEMPERA-TURE, OR OVERPRESSURE, WHERE APPLICABLE) SHUTDOWN DEVICE(S), THAT OPERATES TOTALLY INDEPENDENTLY FO THE PRIME MOVER CONTROL DEVICE(S) TO PROTECT AGAINST RUNAWAY OR DAMAGE TO THE ENGINE, TURBINE, OR OTHER TYPE OF PRIME MOVER WITH POSSIBLE PERSONAL INJURY OR LOSS OF LIFE SHOULD THE MECHANICAL-HYDRAULIC GOVERNOR(S) OR ELECTRIC CONTROL(S), THE ACTUATOR(S), FUEL CONTROL(S), THE DRIVING MECHANISM(S), THE LINKAGE(S), OR THE CONTROLLED DEVICE(S) FAIL.

ANY UNAUTHORIZED MODIFICATIONS TO OR USE OF THE EQUIPMENT OUTSIDE ITS SPECIFIED MECHANICAL, ELECTRICAL, OR OTHER OPERATING LIMITS MAY CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE, INCLUDING DAMAGE TO THE EQUIPMENT. ANY SUCH UNAUTHORIZED MODIFICATIONS: (I) CONSTITUTE MISUSE AND/OR NEGLIGENCE WITHIN THE MEANING OF THE PRODUCT WARRANTY THEREBY EXCLUDING WARRANTY COVERAGE FOR ANY RESULTING DAMAGE, AND (II) INVALIDATE PRODUCT CERTIFICATIONS OR LISTING.

TO PREVENT DAMAGE TO A CONTROL SYSTEM THAT USES AN ALTERNATOR OR BATTERY-CHARGING DEVICE, MAKE SURE THE CHARGING DEVICE IS TURNED OFF BEFORE DISCONNECTING THE BATTERY FROM THE SYSTEM

ELECTRONIC CONTROLS CONTAIN STATIC-SENSITIVE PARTS. OBSERVE THE FOLLOWING PRECAUTIONS TO PREVENT DAMAGE TO THESE PARTS.

DISCHARGE BODY STATIC BEFORE HANDLING THE CONTROL (WITH POWER TO THE CONTROL TURNED OFF, CONTACT A GROUNDED SURFACE AND MAINTAIN CONTACT WHILE HANDLING THE CONTROL).

AVOID ALL PLASTIC VINYL, AND STYROFOAM (EXCEPT ANTISTATIC VERSIONS) AROUND PRINTED CIRCUIT BOARDS.

DO NOT TOUCH THE COMPONENTS OR CONDUCTIONS ON A PRINTED CIRCUIT BOARD WITH YOUR HANDS OR WITH CONDUCTIVE DEVICES.

Section 1: General InformationIntroductionThe VR-300 model is a multifunction protection unit packaged into one compact device. Typical applications are generators and switchgear equipment that require independent protection archi-tecture to implement transfer schemes.

Measurement Value LoggingVoltageVoltage is displayed as three-phase R.M.S. measurement of the phase-neutral and/or phase-phase voltages. The unit utilizes sin-gle-phase R.M.S. measurement of the synchronizing voltage VL1-L2.This device can be ordered with the following measuring voltage input ranges (rated voltages). Please indicate the measuring volt-age input required when ordering (refer to Appendix B: Technical Data on page 23): 66 V/115 V...... [1]FrequencyFrequency measurement is extracted from the digitally filtered measuring voltages. The frequency is measured 3-phase if the measured voltage exceeds 15% of the nominal voltage. This ensures rapid and precise measurement of the frequency. How-ever the frequency is still measured correctly even if voltage is only applied to one phase.

Functional DescriptionsThe unit is equipped with the following functions.General functions: One ready for operation relay output (normally open contact); One additional, freely configurable relay output (change-over

contact); Discrete input for blocking of protective functions or remote

acknowledgment; Password system; Wide-range power supply (90 to 250 Vac/dc); and Synch-check function
