Manually Adjusting the Pump Speed
When the motor control is set to manual operation, the pump speed can be
adjusted from 0-94 rpm.
NOTE: When the motor control is set to automatic operation, pressing the
motor speed arrow keys will alter the ratio of the line speed reference signal
to allow for fine‐tuning of the adhesive output rate.
Adjust the Motor Speed for Manual Operation
CAUTION! To ensure adequate motor control and cooling, the
recommended minimum pump speed is 18 rpm or greater. To prevent
excessive wear on the pump, avoid prolonged operation of the pump at
speeds greater than 80 rpm.
1. Use the following formula to determine the best pump speed:
pumpspeed[rpm] +
desiredflowrate[gńmin]
adhesivedensity[gńcc] pumpoutputrate[ccńrev]
2. Press the pump speed arrow keys to adjust the motor(s) to the desired
speed (rpm). Each press of an arrow key increases/decreases the motor
speed by 1 rpm.
The current motor speed is indicated on the display.
NOTE: You can change the amount by which the motor speed increases
or decreases (1%, 1 rpm, 0.5 rpm, etc.) upon each press of an arrow key
by changing the value of the motor control SEt parameter. Refer to
Changing a Motor Control Parameter in Section 6, Troubleshooting.
