Fig. 10-27 R.p.m. sensor 663P8001 delivered up to September 2003
Speed nominal range (164... 819 Digit)
• I 300 ... 3000 pulses/min (Standard)
• II 800 ... 4000 pulses/min (Standard)
• III 1000 ... 8000 pulses/min
Range which is theoretically, technically possible (140-941 Digit)
• I 200 ... 3500 pulses/min
• II 680 ... 4600 pulses/min
• III 740 ... 9310 pulses/min
Only 2 wire NAMUR.
If the set pulse range is exceeded the value remains at the upper end of the range (higher
pulse numbers are ignored).
Below the measuring range the signal goes to 0 (approx. 0 - 7 digit).
CAUTION!
Make sure that the selected measuring range is not exceeded, otherwise speed changes in
excess of this will no longer be detected.
(new version delivered from October 2003 onwards)
In ETAMATIC S OEM, a r.p.m board can be integrated, allowing you to connect an inductive
sensor for speed feedback directly. It could be a NAMUR type or a three wired type.
