Particularly suitable for steam plant operation to TRD 602/604. Design All-electronic logic unit SRL-63 for continuous monitoring, with three LEDs (stand-by, purging, switching off) with case for mounting on walls. Operation The monitoring equipment with Mini-PLC periodically activates a memory for a defined period of time. During this period the memory registers all functional operations, e. g. purging of the level pot. If this signal is not received within the fixed period, the plant is shut down. The plant is also shut down if the purging process lasts for more than five minutes.
