4.1.1.5 QRA2 / QRA4 / QRA10 with AGQ1 (for intermittent operation only)
Β
Note!
AGQ1 is only available for AC 230 V mains voltage.
Power supply in operation DC 280…325 V
Power supply in test mode DC 350…450 V
Attention!
In order to ensure that a higher voltage is supplied to the UV cell for the
extraneous light test in phase 21 (via fan output X3-01 pin 1), parameter
MinTmeStartRel (minimum time for phase 21) must be parameterized to at least
5 seconds.
For more detailed information about QRA2 / QRA10, refer to Data Sheet N7712.
For more detailed information about QRA4, refer to Data Sheet N7711.
Caution!
Flame detectors QRA2 / QRA4 / QRA10 must not be used when extraneous light
suppression is activated since detector tests are not made in that case
(parameter ExtranLightTest = deactivated)
Possible ionization current Max. DC 10 µA
Display flame approx. 100%
(with factory setting of the parameter
StandardFactor)
Ionization current required Min. DC 6 µA
Display flame approx. 50%
(with factory setting of the parameter
StandardFactor)
Permissible ionization current during
extraneous light test
Max. DC 0,3 µA
In connection with the LMV5, ancillary unit AGQ1.xA27 must be used.
Power supply AC 230 V
Possible current Max. 500 µA
