a safe level regardless of motor load or input from the tension-arm. This pot is
factory pre-set to suit ½ hp motors. Should changes be required in the
field, proceed as follows: Monitor the motor current. Advance the pot slowly
until the desired current is achieved. This should not exceed 125% of the
motor nameplate rating. Do not stall the motor for more than a few seconds,
or damage may occur.
Trip:
The output relay located on SCR Board (Outputs: Com, NO, NC)
is energized when the current flowing between
DC “+”
and
DC “-“
overshoots
the level selected on the pot marked
“Trip.”
It de-energizes when the current
falls below the normal current by approximately 5% or when power to the board
breaks.
