ANTIFLOOD DETECTOR LEVEL CONTROLS Activates alarm if water on floor Inputs: up to 3 sensors for water detection Outputs : – 1 SPDT relay – 1 On-Off optoisolated electronic control Alarm in three-module enclosure for mounting on DIN rail Power supply 230 Volt ~ Application The flood alarm is for use in spaces where water leakages could occur; leakages which, if not dealt with in time,could lead to hazardous situations or cause serious material damage. A typical use for this alarm is to detect the presence of water on the floor of a heating plant. The alarm comprises two units: • • UAL 358 : the detector which signals the alarm and sends the output instructions, SAL 500 : this is the sensor which monitors the presence of water or other liquids having a minimum conductivity of 60 MicroSiemens. All data and contents of this card are the exclusive property of Riels Instruments The mineral water with a low content of residues has a conductivity of about 150 MicroSiemens. Normal aqueduct water has a minimum of about 100 MicrSiemens.

Installation UAL 538 detector: This must be installed in a dry location that respects the ambient conditions given under 5.TECHNICAL DATA. If installed in a location classified as “Hazardous” it must be installed in a cabinet for electrical equipment constructed according to the regulations in force for the class of danger concerned. The controller can be mounted on a DIN rail and housed in a standard DIN enclosure. SAL 500 sensor: This can be secured to the floor and in this position the poles detect the presence of water at a height of two millimetres. If it is preferred to measure the...
