Jumper A closed: fuel signalling outputs (Kl. 88/90) are active only, if burner
runs (that is fan is ON).
Jumper A open: fuel signalling outputs are also active when burner is not running
(this is equivalent to R16 version 3).
Jumper B: not used
*) At terminals 82 through 86 an alternating testing current must flow. Otherwise the relais module will switch off all
outputs during the self-test which forces the FMS to do a fault-shutdown. At a mains voltage of 230V an
impedance of Z<=100k
W
is required. At 110V Z must be 22k
W
or less. If necessary connect an appropriate
auxiliary load (as a resistor or RC element). Outputs which are not switched on by the FMS (e.g. ignition valve
when starting without ignition burner) need no auxiliary load.
