FMS Commissioning Run to shut-off limits
Checking the shut-off limits This test is necessary with the use of continuous actuators and with
at the continuous output r.p.m.regulation without the use of O /CO-regulation affecting these r.p.m.

of the FMS With using O regulation it can be abandonned, if the excesse air at
2
deactivated O2/regulation is higher than the setpoint
Selector switch (1) to "Load rating”
Run to load point to be checked
Wait until the system has run to that point
Mode selector switch (2) to "Setting”
Adjust set-point value (4) of the continuous channel in the air deficiency
direction until the actual value feedback has changed by the set number
the set number of points (1. monitoring band parameter 62-76)
Wait until the system has run to that point
Mode selector switch (2) to "Setting”
Check firing
Reset set-point value (4) to its origin value
Check firing
Reset set-point value (4) to the next continuous channel in air
deficiency direction.
Check firing
Repeat, until all continuous channels are checked at their limits.
___________________________________________________________________
If a correction affects the continuous channel, the test can be omitted, if the
correction range is bigger than the adjusted monitoring band (what is ordi-
narily the case). Instead the firing has to be checked at maximum correctio-
nal intervention. See section 2 "Checking the O influence". The test can
2
also be omitted if the monitoriing band is set to 0 at the air deficiency side.
___________________________________________________________________
As the case may be the above described inspection has to be examined in
direction excess air than in direction air deficiency, if it cannot be ensured,
that with the adjusted excess air limits,
the combustion boundary values
The correction value can be altered as follows in order to set the correction
range and to check the combustion boundary values.
Burner on, regulator is enabled (terminal 4).

If the system is not equipped with an extra O2- or CO-monitor, it has to be
