Operating Instructions
24
To test the RCD operating time, fi rst identify the rated
residual operating current of the RCD under test and
press the appropriate button (10mA or 30mA) to begin
the test.
The mains supply status is checked and the status
is indicated using the LN, LE and NE enunciators of
the LCD.
PAC3760 DL
If the mains supply is incorrect, testing is inhibited.
If the mains supply status is correct then the 0° test
will be performed, when the RCD is reset then the
180° test will be performed. Ensure that both tests are
performed for each RCD.
The operating time for each RCD test will be shown
on the PAC3760 DL display.
For 10mA RCD tests the PAC3760 DL will indicate a
pass for
≤
40ms.
For 30mA RCD tests the PAC3760 DL will indicate a
pass for
≤
300ms.
