for electrical and mechanical testing and calibration of multi-turn actuators SA(R) or part-turn actuators SG

Tests which have so far only been possible on the manufacturer's  premises can now be performed on site using the test bench PV 1236.

With the test bench, electric actuators up to a max. torque of 500 Nm (optional: 1,000 Nm) can be tested.

The test bench consists of 3 separate units:

Service unit PV 788 B

for power supply and the operation of the actuator as well as for the measurement of the electric data

Measuring unit module

for the evaluation of the sensors of the measuring bench and therefore for the measurement of the mechanical values

Measuring bench with:

• Braking system 
• Rotary encoder
• Mounting flange 

Functions:

• Testing of the basic functions of the actuator (OPEN-STOP-CLOSE) 
• Calibration of the torque switching
• Measurement of the actuator stall torque
• Setting of the limit switches 
• Measurement of the output speed 
• Measurement of the swing angle 
• Monitoring or indication of the switch functions 

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
• Braking system with a disc brake with two independent calipers 
• Incremental encoder 
• Output drive types according to ISO or DIN standard

Options:

• Extension of the measurable torque range to 1,000Nm

Interfaces:

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