a) For applications in accordance with EN/ IEC 60079-29-4 or FM 6325, the full scale deflection must at least amount to 4 LEL-m for
Pulsar 7700 RX
b) For applications in accordance with EN/ IEC 60079-29-4 or FM 6325, the full scale deflection must at least amount to 5 LEL-m for
Pulsar 7900 RX
c) For applications in accordance with IEC 60079-29-4, the following values must not be exceeded:
0.3 LEL-m for full scale deflection 8 LEL-m
0.15 LEL-m for full scale deflection 4 LEL-m.
d) For applications in accordance with IEC 60079-29-4, the following values must not be exceeded:
0.05 LEL-m for full scale deflection 8 LEL-m
0.025 LEL-m for full scale deflection 4 LEL-m.
e) 0.5 mA ... 3.5 mA with SIL lock
f) "Warning" is only deactivated on the 4-20 mA interface. "Warning" will still be issued on the HART
g) In strong mode, the transmitter is operated with an increased flash frequency. The receiver requests this operating mode via the DIGITAL
LINK connection.
h) "Fault" is only deactivated on the 4-20 mA interface. "Fault" will still be issued on the HART
