Startup
Burner adjustment data
Adjusting the gas pressure switch
·
To adjust the shutoff pressure:
Remove the cover of the gas
pressure switch.
·
Activate burner and adjust gas
pressure upstream of valve assembly
by turning the ball valve until the
desired shutoff pressure is set.
·
Turn the dial clockwise until the gas
pressure switch shuts down the
burner.
Adjusting the air-pressure switch
·
Remove transparent cover.
·
Provisionally adjust air-pressure
switch to minimum setting.
Checking for correct functioning
The flame-monitor should be checked
for safe and reliable functioning before
initial startup, during regular servicing
and after any extended shutdown
period.
–
Startup attempt with closed gas
valve: Note that the control unit
MUST go into malfunction mode at
the end of the safety period.
–
Normal startup - if burner is in
operation, shut gas valve: after the
flame goes out, the control unit must
go into fault mode!
–
Normal startup ; interrupt
air-monitoring contact during
preliminary ventilation or operation:
Control unit should go into fault mode
IMMEDIATELY.
–
Bypass air-pressure switch before
startup: Burner activates for approx.
2-3 sec., before carrying out fault
shutdown. After 10 sec., this brief
malfunction is automatically reset by
the control unit, and a second startup
attempt ensues (motor activates for
2-3 sec.). If the LW contact is still
closed (e.g. due to fused contact)
resulting in genuine emergency
shutdown. However, if the LW
contact has opened within these 10
sec. (e.g. due to decelerating motor),
normal operation ensues.

The above adjustment data correspond to the
default settings
. Pre-delivery adjustment settings appear within a black
rectangle. These settings allow the burner to be run in normal operation, but always carry out a careful check of adjustment
settings, as individual plant conditions may require certain corrections.
