Note:
When valve proving is activated (e.g. on shutdown), the load on the valve’s
terminals (according to chapter Technical data/Terminal rating Outputs) is
restricted.
Fuel valve 1 X7-04 pin 4/fuel valve 2 X7-02 pin 3/auxiliary output AUX
 Rated voltage AC 120 V AC 230 V
50/60 Hz 50/60 Hz
 Rated current 1 A 1 A
 Power factor cos >0.4 cos >0.4
If the terminal load (according to chapter Technical data/Terminal rating
Outputs) is not reduced (max. rated current 2 A, cos >0.4), the design
lifetime will be reached after about 100,000 burner startup cycles!
