Logic Unit SRL 6-50
If the level electrode (high or low level limiter) is installed in an isolatable level pot outside the boiler, make sure that the level pot is drained and the connecting lines are rinsed at regular intervals.
For this purpose the connecting lines must be shut off and opened at regular intervals and by opening and closing the drain valve the lines and the level pot will be rinsed.
The logic unit is designed to be used in conjunction with level switch NRS 1-50 (water level limiter) or level switch NRS 1-51 (high level alarm) to monitor the correct timing and sequence of valve operations.
During the rinsing process the level switch jumpers the level electrode, thus preventing the safety or control circuit from opening. The level switch - controlled by the logic unit - also monitors the rinsing and bypass time.
