Setup

6.1

The switching status of the electronics can be checked via the signal

lamps (LEDs) integrated in the upper part of the housing.

The signal lamps have the following meaning:

•

Green lights - voltage supply connected

•

Yellow lights - vibrating element covered

•

Red lights briefly - function test during instrument start (for approx.

1 s)

•

Red lights - shortcircuit or overload in the load circuit (sensor

output high-impedance)

•

Red flashes - Error on the vibrating element or the electronics

(sensor output high impedance)

6.2

The SITRANS LVL100 has an integrated function for simulation of the

output signal which can be activated magnetically. Please proceed as

follows:

→

Hold the test magnet (accessory) against the circle symbol with

the label "TEST" on the instrument housing

Fig. 9: Simulation of the output signal

The test magnet changes the current switching condition of the instru-

ment. You can check the change on the signal lamp. Please note that

all connected device are activated during the simulation.

If SITRANS LVL100 does not switch over after several tests with the

test magnet, you have to check the plug connection and the con-

nection cable and try it again. If there is no switching function, the

electronics will be defective. In this case you have to exchange the

electronics or return the instrument to our repair department.

Caution:

It is absolutely necessary that you remove the test magnet from the

instrument housing after the simulation.
