6.4 Connection supply
First check, if the existing supply voltage agrees with the voltage version of the switching
amplifier should be checked first (see marking on the circuit board).
230 V ~
LSO.25-X1X
115/120 V ~
LSO.25-X2X
24 V ~
LSO.25-X3X
24 V =
LSO.25-X4X
24 V = without potential separation
LSO.25-X7X (only for standard)
At the plastic case version the line terminals "supply" is marked with the operating
voltage in addition and it is the connection to see directly from the imprint. Carry out the
connection in accordance with "Connection diagram transducer and switching amplifier"
on page 22.

6.5 Connection relay
The signals "signal" and "failure" are provided for per a relay with change over contacts.
These are potential-free and can be used for every arbitrary application. At the mounting
case version the connections can be seen directly from the imprint on the pcboard.

6.6 Function control
After wiring been carried out and checked the supply can be switched on. One of the
yellow LED's should come on now. By pressing the button "test" at closed switch S2 (time
delay turned off) one of the two yellow LED shines approx. 1 s. After this the other yellow
LED is flashing as long as the test button remains pressed. This shows that wiring and
switch amplifiers are all right. If this should not be the case, follow the justage instructions
see chapter "7.2 Adjustment with CAL".
Please observe the actions to be taken in the event of any faults that may
occur, see chapter "10. Troubleshooting".
