• Gently rotate speed selection stim to desired speed (see Figure 7a). • Re-install (2) timer cover screws. 9. Troubleshooting Figure 7a When the pump is first started, the shaft may rotate slowly until water has fully penetrated the bearings. If the pump does not run, the shaft ...
UPM3 UPM3 is the right choice for all projects and appliances produced on a big scale where only one specific external control mode with one specific speed range is requested. UPM3 is controlled via a signal cable entry. UPM3 FLEX AC By combining 2 PWM profiles, the UPM3 FLEX AC brings...
is possible to adjust the speed of the motor in response to a certain input parameter. By choosing the input parameter and at least one operator and one action of the pump it is possible to create an individual user application or user function for the pump control which fulfills the indivi...
