INSTALLATION
Rotate both the VOLTS and MINUTES adjustments
counter-clockwise, to their lowest setting. The 3-phase
wiring should be connected to the terminals marked A,
B and C.
The control wiring will be connected to the opposite end
of the unit, to the terminals with the relay contact
markings. The markings printed on the Model 265 are
the failed condition of the contacts.
When power is applied to the unit, the TRIP LED
indicator should not be lit (the reset switch may have to
be pressed on manual reset versions). If the TRIP
indicator comes on when power is applied, check that
all three phases are present and of the correct voltage.
If the voltage is correct, remove power, then reverse
two of the three phase wires.
Re-apply power. The TRIP indicator should not be on.
After a brief delay (approx. 20 seconds) the LED
indicator marked NORMAL should come on, and the
contacts will transfer.
ADJUSTMENT SETTINGS
Rotate the VOLTS adjustment clockwise, until the
contacts trip and the TRIP indicator illuminates.
Slowly rotate the VOLTS adjustment counter-clockwise,
until the LED goes out (on manual reset versions, hold
the RESET button down while making this adjustment).
After approximately 20 seconds, the contacts will
transfer and the NORMAL indicator will come on. If
nuisance trips occur, rotate the VOLTS adjustment
slightly farther, counter-clockwise. This method of
adjustment will be correct in most cases.
Set the MINUTES delay as required. Application
dependent.
TROUBLESHOOTING
Should the Model 265 Monitor fail to operate properly,
check that all three voltages are present, and are of the
correct voltage level and phase rotation (a Model 108A
or 108B Phase Sequence Detector should be used to
verify phase rotation). Check all fuses and verify that all
wiring connections are correct. If problems persist,
contact your local Time Mark Distributor, or the factory
for assistance.
