Page 5: Use In Compliance With Regulations
2. Use in compliance with regulations The self-monitoring low water level limiter SMLC1 in combination with the level electrodes EL 030 or EL 19-2 is a multi-dynamic limiter of a special type in accordance with DIN VDE 0116 and Wasserstand 100. The self-monitoring control system (SMC) enables first failure identification at the time of occurrence and immediately switches off the downstream relays. -
Page 6: Operating Principle
3.1 Operating principle SMLC1 The SMC system is capable of identifying any possible first failure the moment it occurs and switching off the downstream relays. Failure to detect a fault is therefore impossible. As further dynamic monitoring, the periodic overall test of the device takes place every 2 minutes for one second as a fully automatic process. -
