INSTALLATION
Connect 3-phase wiring to the terminals marked A, B and C.
Connect the control wires to the terminals with the relay
contact markings. The markings shown are in a TRIPPED
condition.
Apply power. If the indicator lights are ON, and the contacts
do not transfer when power is applied, check that all three
phases are present and of the correct voltage. If all phases
are correct, rotate the UNDER VOLTS adjustment fully
counter-clockwise, and the OVER VOLTS adjustment fully
clockwise.
If the contacts still do not transfer, remove power from the unit,
and reverse two of the three input wires. Re-apply power.
The contacts should then transfer (LED-off).
ADJUSTMENT
Turn the DELAY SECONDS trip delay adjustment counter-
clockwise.
Rotate the UNDER VOLTS adjustment slowly clockwise until
the contacts transfer to a tripped condition (LED-on).
Slowly turn the UNDER VOLTS adjustment back counter-
clockwise until the contacts reset to the normal condition
(LED-off).
Rotate the OVER VOLTS adjustment counter-clockwise until
the contacts trip (LED-on).
Slowly turn the OVER VOLTS adjustment back clockwise until
the contacts reset to the normal condition (LED-off).
These settings will be correct for most installations.
