Performance test

As part of the performance test a value is simulated that exceeds the measuring range

limit of 12000 µS/cm of the conductivity electrode. The equipment must response as if the

MAX limit were exceeded.

Press button briefly.

LED 1 and 4 are flashing rapidly.

LED 4 is illuminated during intermittent boiler

blowdown.

The test mode remains active for 10 seconds.

Press button and wait until LED 1 is illuminated.

Relay contact 1 opens.

As long as the button is pressed down a conductivity

value greater than 12000 µS/cm is simulated.

Please note when using the equipment as conductivity limiter

Test

Note

The control unit LRR 1-40 does not lock automatically when the adjusted

MAX limit is exceeded.

If a lock function is required by the installation it must be provided in the

following circuitry (safety circuit). This circuit must meet the requirements of

DIN VDE 0116, prEN 50156-1.
