Long Range:
120 - 200m (390 - 650ft)
Speed of Response T90 less than 3 seconds
Output Signal 4 – 20 mA
Normal operation
(linearised 0 – 5 LELm)
0 mA
Fault
2 mA Inhibit 2.5 mA Beam block* 3 mA Low signal 21 mA Overrange
*Searchline Excel will indicate Beam Block after 30 s without signal. After a further 120 s it will indicate Fault. These values are
programmable; please refer to Appendix A for details. To comply with FM performance approval, the maximum value for Time to Block
is 200 s.
Note: For safety reasons, if Searchline Excel loses signal while measuring a gas reading above its internal Alarm threshold (default
1 LELm) it will not indicate beam block. Instead it will hold the previous gas reading until it is again able to measure the current gas
concentration. Operator intervention may be required to remove a blockage from the beam.
