DANGER!
Explosion risk due to leaking fuel or release of
additional units!
Downstream units (e.g. burner/igniter) can be
connected via incorrect operation of the gas fired
igniter.
– The gas fired igniter, and the flame monitor
signal of the gas fired igniter should be
incorporated into an overriding safety controller.
– Only use measurement sockets for short term
measurement purposes on site.
– Do not use measurement sockets for distance
or continuous display.
– Do not bridge measurement sockets, or bring
them into contact with mass under any
circumstances.
– On commissioning, it must be ensured that in
the case of a flame signal breakdown, the flame
signal contact opens within 1 s, and leads to
the safety and fault shutdown via the overriding
safety controller.
