Rapid-Air PALLET MASTER (PMD) HIGH SPEED: 35, 50 & 100 SERIES - Manual (Page 13)

OPERATION
Before operating the control, carefully check that all connections are correct. Check that there
are no wire chips or other foreign material on the printed circuit boards. Make sure that the in-
put voltage is the same as listed on the control nameplate.
FIRST TIME STARTUP
1. Set the direction select Speed Adjust Pot to approximately its center position. If this pot is
wired for unidirectional operation, set the pot to full CCW. Apply AC power to the unit.
2. If Regen Run-Brake switch is used, place it in the open position.
3. If Start and Stop pushbuttons are used press the Start button. (If not used, terminals 10 and
12 must be jumped.)
4. Slowly turn the direction select Speed Adjust Pot CW or CCW for the desired direction of
motor rotation and speed. If the Speed Adjust Pot is wired for unidirectional operation
slowly turn it CW to the desired speed. Verify that the motor starts slowly and increases
speed in accordance with the potentiometer setting. If the control does not behave as ex-
pected, disconnect the AC power immediately and refer to the Troubleshooting Section of
this manual.
OPERATING PROCEDURES
The motor may be started or stopped with the power line at any speed setting on the direction,
select speed adjust pot or unidirectional speed adjust pot. When power is applied the motor will
accelerate to the set speed and when the power is disconnected the motor will coast to a stop.
For a fast stop the operational Regen Run-Brake switch should be used. When placed in the
BRAKE position the motor will then be regeneratively braked to a stop.
For push button operation, the Regen Run-Brake switch must be in the open position. When
the Start button is pressed the motor will accelerate in the direction and to the speed as selected
by the direction select Speed Adjust Pot. (If the Pot is in the center position the motor will not
begin to run until the Pot is turned off center.) If the speed adjust pot is wired for unidirectional
operation the motor will accelerate to the speed selected. If the motor runs in the wrong direc-
tion, disconnect power from the control and interchange the leads to terminals A1 and A2.)
When the STOP button is pressed the motor will coast to a stop.
CALIBRATION INFORMATION
SAFETY WARNING: Dangerous voltages exist on the printed circuit board. Contact with
components and/or printed circuitry could cause serious injury or fatality. Please refer to and
follow all Safety Warnings.
