QRA2 / QRA4 / QRA10 with AGQ1 (for intermittent operation only)

Note!
AGQ1 is only available for AC 230 V mains voltage.
Power supply in operation
Power supply in test mode
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)
