Insulated amplifier
The PXUB 201 insulation amplifier is connected to the voltage output of the tension electronics. S1 is usually set to a voltage ratio of 1:1. Output is selected through switches S1 and S2 to generate voltage or current output. Slow response is selected by switch S2 (position 3). The switch is located inside the unit. Figure 3-17. Insulating amplifier PXUB 201 must be turned on to set switches S1 and S2. 1. Remove the insulation amplifier from the DIN rail. Use a screwdriver to remove the spring at the bottom of the insulation amplifier. 2. Press the spring locks on both sides of the insulation amplifier. 3. Pull off the top cover until you see switches S1 and S2 Set switches S1 and S2. 5. Slide the top cover back to the locked position. 6. Reinstall the insulation amplifier on the DIN rail.

As long as the system is turned on, the measurement will continue to run. However, you need to know how to start and shut down the system, see section. Starting and shutting down 2 Safety instructions Before starting any operation, read and follow the safety instructions given in Chapter 1 "Introduction". However, if local regulations are more stringent, priority should be given 3 The LED indicator and operation keys of the operating device are shown in Figure 1. The power status backlight LCD displays the backward backward normal (confirm) LED "power" LED "status" or cancels the tension electronic device PFEA111/112. Chapter Operation 3BSE029380R0001 in the User's Manual. Start and close.. 1 Start Use the external ON/OFF switch (not provided by ABB) to start and close the tension electronic device.
During normal maintenance
No action by the operator is required. 1. Check whether the main tension control machine is ready for normal operation. 2. Turn on the tension electronics by setting the external on/OFF switch to the on position. For IP 65 version (NEMA), also set the internal switch to "on". 3. Check: - The display is on - The "Power" indicator is on - The status indicator is on (green). A red light indicates an error 2 OFF Turn off the tension electronics by setting the external ON/OFF switch to the OFF position 5 The measuring equipment in normal operation shall be permanently opened to obtain the best measurement results. This allows load cells and electronics to operate at uniform temperature conditions. The measuring equipment is designed for continuous operation.
