4.5 Inputs and outputs
4 Burners
4.5.2 Element's outputs
Element's outputs 4- E/As_Ausgänge  SV1: Safety valve 1
Safety valve 1 is activated via this output. Safety valve 1 is on the fuel
side.
SV 1 = 0: Close safety valve 1
SV 1 = 1: Open safety valve 1
If the safety valves are activated via relay outputs, the special re-
quirements of EN 50156 must be considered. We recommend that
the safety valves are activated via the PNOZmulti expansion module
PNOZ mo5p (see section entitled "Examples", under "Connecting
the safety valves").
 SV2: Safety valve 2
Safety valve 2 is activated via this output. Safety valve 2 is on the
burner side.
SV 2 = 0: Close safety valve 2
SV 2 = 1: Open safety valve 2
If the safety valves are activated via relay outputs, the special re-
quirements of EN 50156 must be considered. We recommend that
the safety valves are activated via the PNOZmulti expansion module
PNOZ mo5p (see section entitled "Examples", under "Connecting
the safety valves").
 IV: Ignition valve
The ignition valve is activated via this output.
IV = 0: Close ignition valve
IV = 1: Open ignition valve
 VV: Vent valve
The vent valve is activated via this output. If tightness control is not
configured but continuous vent is, this valve must be designed to be
"normally open". If neither tightness control nor continuous vent is
configured, the output is inactive.
VV = 0: Close vent valve
VV = 1: Open vent valve
 IGNT: Ignition transformer
The ignition transformer is activated via this output.
IGNT = 0: Switch off ignition transformer
IGNT = 1: Switch on ignition transformer
