the unit are the failed condition of the contacts.
AUTOMATIC RESET VERSIONS:
Apply power. If the contacts do not transfer (TRIP LED-Off),
check that all three phases are present and of the correct
voltage.
If all phases are correct, rotate the VOLTS adjustment
potentiometer counter-clockwise, to the low position.
If the contacts still do not transfer, remove power from the unit.
Reverse any two of the three input wires and re-apply power.
The contacts should transfer to the energized condition; N.O.
contact-closed, NORMAL LED-On.
MANUAL RESET VERSIONS:

ADJUSTMENT SETTINGS
NOTE: During adjustment, you may wish to install a jumper
across the control contacts, to prevent cycling the load on and
off.
AUTOMATIC RESET VERSIONS:
Rotate the VOLTS adjustment slowly clockwise, until the
contacts transfer to the failed condition (TRIP LED-On).
Slowly turn the adjustment back counter-clockwise, until the
contacts reset to the normal condition (TRIP LED-Off).
Remove the jumper, if installed. This setting will be correct for
most applications.
If nuisance tripping occurs, turn the adjustment slightly farther
counter-clockwise.
In adjustments to eliminate nuisance
tripping, the VOLTS adjustment
small increments, until the true nuisance trips are eliminated.
MANUAL RESET VERSIONS:
During adjustment, you will need to press and hold the RESET
button.
Rotate the VOLTS adjustment slowly clockwise, until the
contacts transfer to the failed condition (TRIP LED-On). A
slight buzz in the contacts may occur when the relay is at the
transfer point to the failed condition. This is normal and will
not occur in operation.
Slowly turn the VOLTS adjustment back counter-clockwise,
until the contacts reset to the normal condition (NORMAL LED
-On).
Release the RESET button, and remove the jumper, if
installed. This setting will be correct for most applications.
If nuisance tripping occurs, turn the adjustment slightly farther
counter-clockwise.
In adjustments to eliminate nuisance
tripping, the VOLTS adjustment
small increments, until the true nuisance trips are eliminated.
