DISPLAY DESCRIPTION
L1 Power on
when lit indicates that supply is present at the card and the controlling circuits.
L2 Braking
when lit indicates direct current braking.
L3 Motor turning
when lit during motor rotation, indicates dynamo voltage presence at terminals 1 and 2.
L4 Emergency
when lit indicates an irregular situation due to: overload, absence of on-line and motor
phase, absence of a tachometrical dynamo, or tachometric polarity inverted if the internal
precision rectifying device has not been used. In this case, the motor cannot rotate and
the externally connected emergency relay is commanded. This situation is self-maintained
and can only be unblocked by removing current from the card. If the L4 pilot light lights
up, consult the “TROUBLESHOOTING ” paragraph on page 12.
L5 Stop in ramp
when lit indicates the presence of an active command at terminal 4. In this case the
motor stops with the deceleration ramp set up to zero revs.; the led must be switched off
for the motor to start again.
L6 Running
when lit indicates the presence of an active command at terminal 5. In this case the
motor can rotate;
when unlit indicates that the motor cannot rotate.
INSTRUCTIONS FOR CONNECTING ROWAN MOTORS
CONNECTING THE POWER TERMINAL BOARD
Even if power terminal board connection goes through the speed control drive, it remains the same as a normal threephase
asynchronous motor, therefore if the following is written on the motor plate,follow the relative instructions:
ELECTRICAL CHARACTERISTICS TABLE OF THE MOTORS THAT CAN BE FIT TO THE 390S BOARD
The motor protecting circuit breaker should be calibrated for a current which is 15% higher than the nominal one. For
motors with line voltages of 240-415-440-460V, the relevant absorption data can be obtained by taking the 400V line
voltage figures and proportionally calculating the line voltage of the motor to be used.
