Characteristics
- monitors temperature of motor winding
- sensor PTC which is in-built in motor winding (or external sensor or bi-metal con-
tact) is used as monitoring element
- PTC sensor is used for sensing, It is in-built in motor winding by its manufacturer
- MEMORY function - active by DIP switch
- RESET of faulty state:
a) button on the front panel
b) by external contact (remote by two wires)
- function of short-circuit or sensor disconnection monitoring, red LED fl ashing in-
dicates faulty sensor
- output contact: 2x changeover 8 A / 250 V AC1
- red LED shines and indicates exceeded temperature
- terminals of sensor are galvanically separated, they can be shorted out by terminal
PE without damaging the device.
- multivoltage supply AC/DC 24-240 V, not galvanically separated
- 1-MODULE, DIN rail mounting
Warning!
In case of supply from the main, neutral wire must be connected to terminal A2.
Sensors could be in series in abide with conditions in technical specifi cation -
switching limits.
