1)
AC voltage, measured with no detector current at AC 230 V mains voltage. Internal resistance of measur-
ing instrument 10 MΩ. The shutter of the flame detector QRA53... / QRA55... is powered by mains volt-
age
2)
Also refer to the specification given on the KF8832 for measuring the detector current
•
3)
Detector cable laid in a minimum distance of 5 cm from other mains carrying cable:
As a multiple cable
-
-
With 5 single wires
•
With a shielding 3-core control cable to terminals 3, 4 and 5 of the flame detector
QRA53... / QRA55... and standard mains cable to terminals 1 and 2
•
With 2 shielding single-core coaxial cables (≤ 45 pF / m, e.g. RG 62) to terminals 3
and 4 of the flame detector QRA53... / QRA55... and standard mains cable to termi-
nals 1, 2 and 5
•
If possible, shielding should be earthed at both ends
4)
Longer cable distances are permitted when connecting low capacitance detector cables to terminal 24 of
the burner control (especially against earthed wires!)
