MK 7850N/500: as MK 7850N/200 but with
• 2 additional functions:
M8676_a
- Cyclic timer, start with break (TP)
- Fleeting on make and break (EW / AW)
• second time setting t
- Cyclic timer, start with pulse (TI) or break (TP), based on the
separate setting of pulse and break time the flasher function
can be used as cyclic timer
- Fleeting on make and break (EW/AW)
- Delay on energisation and de-energisation (AV / RV)
- Delay pulse (IE) and setting of pulse length
• Connection facility for 2 external potentiometers
