Initial Start-Up; Trimpot Adjustment Procedure - DART Controls 530B CONTROL Série Mode D'emploi

1. Check to see that the 115/230 VAC selection switch is set for the desired input voltage.
2. Recheck all wiring. Accidental grounds, loose or pinched wires on armature or speed potentiometer wires may damage the
control when power is applied.
3. See "ADJUSTMENT PROCEDURE" and observe the WARNINGS pertaining to cover removal for adjustments.
4. Preset trimpots for your horsepower by using the "TRIMPOT CHART". NOTE: Options may change the trimpot setting from
this chart. If your control has an option, be sure to carefully read the section in "OPTIONS" that pertains to your option.
5. Turn speed potentiometer to zero (fully CCW).
6. Turn power on and advance speedpot while observing motor.
7. If motor rotation is incorrect, turn power off at external disconnect and reverse the +ARM and -ARM connections.
8. If operation is satisfactory, no re-adjustments are needed.
9. If instability or surging is observed, or if maximum speed is higher than desired, proceed to "ADJUSTMENT PROCEDURE".
10. For other problems, see section "IN CASE OF DIFFICULTY".
WHEN MAKING AN ADJUSTMENT, ALWAYS USE A SCREWDRIVER WITH AN INSULATED SHAFT TO AVOID THE
SHORT CIRCUITING OF PC BOARD COMPONENTS. WHENEVER THE CONTROL COVER IS REMOVED, IT MUST BE
SUPPORTED TO AVOID ACCIDENTAL CONTACT BETWEEN CONTROL CHASSIS AND LIVE COVER COMPONENTS.

TRIMPOT ADJUSTMENT PROCEDURE

Four adjustments (MIN., MAX., I.R. COMP., and CUR. LIM.) are checked at the factory using a typical motor. Use the "TRIMPOT
CHART" to adjust the trimpots to the approximate setting for your horsepower. The other two adjustments (ACCEL and DECEL),
are the Acceleration and Deceleration adjustments and should be set for your particular application requirements. The "TRIMPOT
CHART" is approximate and is valid when using a speedpot or a 0 to 12VDC input signal to control the speed. Operation of the control
beyond ±10% of normal line voltage is not recommended and could result in readjustments. These settings are permanent; periodic
readjustment is normally not needed. (NOTE: Use only an ungrounded voltmeter).
MAX.
Sets maximum motor speed when speedpot is at 100% CW rotation. Clockwise rotation increases maximum
motor speed.
1) Turn drive power OFF!
2) Connect a DC voltmeter; plus to +ARM and minus to -ARM.
3) Set meter voltage range for either 90 VDC or 180 VDC.
4) With no load on the motor, adjust the MAX trimpot to the rated armature voltage as seen on the meter.
NOTE: A tachometer or strobe may be used in place of a meter. Follow the above steps, but adjust the MAX trimpot
to the rated motor base speed, indicated by tach or strobe.
MIN.
Sets minimum motor voltage when Speedpot is set at zero. Clockwise rotation of the MIN. trimpot will in-
crease the minimum motor voltage.
1) Set Speedpot to zero (fully CCW).
2) With no load on the motor, adjust the MIN trimpot clockwise until the motor starts to rotate.
3) Slowly back off the trimpot in the CCW direction until the motor stops.
NOTE: If motor rotation is desired at zero Speedpot setting, adjust the MIN trimpot clockwise until the desired
minimum speed is reached.
I.R. COMP.
Provides a means of improving speed regulation in the armature feedback mode. If a change in motor speed
during a load change is of no concern, rotate this trimpot fully CCW.
1) Set speedpot at 50%.
2) Observe motor speed during a no load condition.
3) Apply a full load to the motor.
4) Adjust the I.R. COMP. trimpot clockwise (while the load is applied) until the no load motor speed is obtained.
