3.  Use in compliance with regulations 

The self-monitoring low level limiter SMHL2 in conjunction with the level probe EL03 or EL19-
2 is a level limiter, an "equipment part with safety function" according to: 

 

EU-Richtlinie 2014/68/EU 

 

DIN EN 12952-11 

DIN EN 12953- 9 

 

DIN EN 61508 -1/ -2/ -3 

DIN EN 61326-1/-3-2 

 

DIN EN 60730-1 

The limiter meets the requirements for own fault detection under SIL3. 

 

Type aproval certificates: 

 

Type aproval due to PED  /  Certificatnumber: 

     01 202 931-B-16-0021 

 

Type aproval due to SIL  /  Registrationnumber: 

     44 799 13775201 

 

Other applied technical rules: 

Waterlevel 100 

 

The limiter is used for monitoring a water minimum fill level in steam boilers. If the water level falls below 
the  minimum (water fill  level) the  limiter  must 

reliably switch off the boiler’s burner control so that no 

overheating of the boiler can occur and thus injury to people or damage to installations is prevented. 
The prescribed minimum water fill  level in the boiler is dependent on the system  and  is given  by the 
boiler manufacturer. Measuring of the water level is carried out via the probes EL030, EL19-2, EL963 
or MS015A/B (see corresponding assembly and operating instructions) which are fitted in the boiler or 
mounting flange. 
When operating a steam boiler system with limited supervision and also when operating without constant 
supervision  the  required  maintenance  procedures  must  be  carried  out  self-monitored  via  control 
equipment on the limiter. 
The permanet self-monitoring ensures the safety function. Thus a test button is not neccessary.
