Operation principle
FUNCTIONS :
* ET : timed on voltage application
* MT : timed on voltage lack
TIMING RANGES :
Two timing ranges (2 different relays) cover a timing range from 0.20 sec. up to 75 min.
Long timing :
* 1/2 range A : 0,5 to 9 mn
* 1/2 range B : 4 to 75 mn
Short timing :
* 1/2 range A : 0,2 to 3 s
* 1/2 range B : 3 to 45 s
Timing range switch and adjustable potentiometer on front face. Red LED indicating the status of the timed contacts and green LED giving the timing status.
