*1 With a pre-ignition time > 100 s or a duty cycle (DC) > 80 % of the ignition output, the maximum permissible
output current is reduced to 1.5 A.
The total currents of all safety-related consumers must not exceed 5 A (note the safety value)
The total currents of all consumers must not exceed 6.3 A (10 A).

Safety chain Potential-free contact 100 m 115 / 230 VAC / max. 5 A
Flame detector 1 (ionisation) Ionisation 10 m Threshold: approx. 1.2 μA
X 16 to X 20
e.g. remote unlocking, air pressure
monitor, heat request, ame detector 2
Switching contact 100 m 115 / 230 VAC
AM 41 display connetion - 10 m internal
Use ame detector 2 for line lengths > 10 m.
For special applications, ionisation line lengths of up to 50 m are possible on request.
Dierent functions can be parameterised for inputs X 16 to X 20, see chapter tbd.
Safety devices in the safety chain must have potential-free normally open or normally closed contacts suitable
for mains voltage and at least 10 A current load.
The connection lines must be suitable for an ambient temperature of at least 75 °C.
