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.

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.
