These units are very versatile as they can be used with all NAMUR, NPN and PNP sensors, functioning with relay ON or OFF load with a timing function in both states. Furthermore they have a programmable time scale from 0,03 seconds to 12 minutes. PROGRAMMABLE FUNCTIONS DELAY The range of delay is from 0,03 seconds and 512 seconds (see table A) distribuited on 9 selectable scales via a dip switch mounted on the front. The selected scale can be adjusted by means of a potentiometer on a graduated scale from 0,05 to 1. It is possible by summing the two scales to obtain full scale values which are different to the standard. This is obtained by placing the switch with the chosen values in the ON position (e.g. pos. 1 an 2 switch ON corresponds to a full scale of 640 seconds). TYPE OF FUNCTION AND SENSOR For this function it is necessary to simultaneously programme the dip switches of position 10-11-12. Following table B it is possible to programme the instrument with an on delay (TE) or off delay (TD) depending on the sensor NAMUR, NPN or PNP. Furthermore it is possible to programme these functions with relay on load (ON) and off load (OFF).
