Switch-off Test
WARNING!
Checking the safety-related parameters by means of a switch-off test
You must check the safety-related parameters of the F152 to ascertain whether they are set
in accordance with the requirements for the furnace to be monitored and to ensure compliance
with the relevant standards.
Check the parameters for adherence to the flame failure detection time
(FFDT) by means of switch-off tests in the relevant performance range and the relevant
modes of the furnace.
Make the flame go out. To do this, you have to shut off the fuel supply of the burner mon-
itored by the F152 (preferably using the quick-action valve).
Check after the flame goes out that the signal for closing the
safety shut-off device within the necessary timescale is triggered.

ument your checks of the parameter settings. This documentary evidence can be included in
the burner's settings log.
