Service unit PV 788 B

The parameters of AUMA actuators are ex works set to the values specified by the customer. However, test run and fine-tuning in combination with the valve has to be performed on site. To this end, AUMA offers the service unit PV 788 B.

In case of faults, the PV 788 B can also be used for diagnosis. Precondition for the use of the device is the operation of the multi-turn actuators with 3-ph AC current. 

Design features:

• End position indication via LEDs 
• Digital display for measured values
• AUMA plug/ socket connector as control and power connection
• Mains plug (CE 3 + N + PE, 32 A)
• EMERGENCY STOP switch

Functions:

• Power supply of the actuator to be tested
• Testing of the basic functions of the actuator (OPEN-STOP-CLOSE) 
• Menu-controlled measurement of all electric data such as:
  - electronic position transmitter RWG
  - inductive position transmitter system IWG
  - Potentiometer
  - Tandem potentiometer
  - Adjusting plate for remote position indicator
  - Motor current
• Measured data logging

Options:

• Supply voltage selection via selector switch 
• Perspex protection cover of the front plate
• Remote control
• Special adapter for actuators with actuator controls AUMA MATIC
• Special adapter for actuators without AUMA plug/ socket connector or non-AUMA products

Interfaces:

• 25-pole Sub-D connector for further processing of the measured data (computer, printer, ...)
