Ramp Time (Adjustable Current Ramp)
The motor current is ramped up from the starting current value over a timed period set by the
ramp time potentiometer (adjustable from 2 to 30 seconds at 400% current limit setting). The
19XL is factory set at 15 seconds. However, based on jobsite conditions, a range of ±5 seconds
is acceptable.
Current Limit
This protection limits motor current to a set value and holds motor torque at a reduced level
during motor start. The current limit is adjustable from 100% to 400% of the motor full load
current value. The current limit is factory set at 250%.
Pulse Start
A pulse start is not used on this machine. It is set to the OFF position.
Current Trip
A control contact closes when the motor reaches a factory set value of 175% of full load
amps. This signal is used as an interlock to shut down the machine if the motor stalls
(increasing load).
Changing Adjustments
The settings are interdependent. If any setting is changed, the other settings should be
checked. Check the settings in the sequence shown above.
