S1 is normally set for voltage 1:1 ratio. The output is selected to generate a voltage or current output by means of switch S1 and S2. Slower response is selected by means of switch S2, position 3. The switches are located inside the unit. Figure 3-27. Insulation Amplifier PXUB 201 You must open the insulation amplifier to be able to set the switches S1 and S2. 1. Demount the insulation amplifier from the DIN rail. Use a screw driver to unload the spring at the bottom of the insulation amplifier. 2. Press down the snap-locks on both sides of the insulation amplifier. 3. Pull the top lid open, until you see both the switches S1 and S2.
