For intermittent operation only.
Note!
AGQ1 is only available for AC 230 V mains voltage.

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!
QRA2 (QRA4 / QRA10 must not be used when extraneous light suppression is
activated since detector tests will not be made in that case!
Possible ionization current
Ionization current required
In connection with the LMV5, ancillary unit AGQ1.xA27 must be used.

When laid together with other cables (e.g. in a cable duct), the length of the 2-core
cable between QRA and AGQ must not exceed 20 m. A maximum cable length of 100
m is permitted if the 2-core cable is run at a distance of at least 5 cm from other live
cables. The length of the 4-core cable between AGQ and LMV5 is limited to
20 m. A maximum cable length of 100 m is permitted if the signal line (ionization /
black) is not run in the same cable but separately at a distance of at least 5 cm from
other live cables.
