Power Supply Test - GE Multilin MIB Instruction Manual

8.6 POWER SUPPLY TEST

8.6POWER SUPPLY TEST
Connect the relay to a power supply at rated minimum voltage indicated in the table below.
A (C1-C2 terminals) a current equal to 0.1 amp.The will trip and close trip contact and OUT1 and OUT4 outputs.
Under these tripping conditions check that theREADY (B5-B6 terminals) output is open, and trip contact (A5-A6 terminals)
and OUT! (A7-B7 terminals) and OUT4 (A7-B10 terminals) auxiliary contacts are closed. Also check that the relay can
communicate with the PC program in case you are using the relay connected to a PC:
Voltage test and maximum consumption is shown below:
Shown values are only illustrative, as due to the nature of the internal power supply (switched power supply), the
consumption currents are high frequency currents, and the meters used measure these values with a poor accuracy.
