Setting guide
After completion of wiring, set the values as following instruction :
1. Set starting period to known motor run up time or to the maximum
if not known with D-Time knob.
2. Set trip delay to desired trip delay time with O-TIME knob.
3. Start the motor and notice run-up time. then, slowly turn the LOAD knob
CCW,
until red LED flashes, where the 100% of the actual
load current is indicated.
Set the LOAD knob to desired trip current. 110бн125%
setting of running
current is recommended.
4. Readjust D-TIME knob setting to normal motor run-up time.
5. Periodic testing with TEST button is recommended to ensure the full protection
and regularly as a preventive maintenance.
