DUNGS has the following require-
ments to ame detectors used with
the MPA51xx:
1. Approval and certication by the
respective bodies (DVGW, DIN
Certco,...) must be ideally pro-
vided.
An independent prove about the
compliance with the respective
demands of the DIN EN298 is
required.
2. The ionisation behaviour of a
ame must be simulated (rectier
eect)
3. The following values are active on
the ionisation input and output
230 VAC +10 % -15 %
The internal resistance of the
MPA is approx 1 MΩ. For safety
reasons, the ame sensor must
work properly also with an internal
resistance of 360 kΩ.
4. Under these conditions, the simu-
lation circuit in the ame detector
must reach at least a direct cur-
rent 3 µA.
If an alternating current with a DC
component is simulated, the DC
component should reach at least
25%.
The current can be derived to N,
PE or returned to N on the MPA.
5. The supply voltage for the ame
detector must be tapped o at the
output ION_PWR of the MPA51xx
(230 VAC, max. 1 A).
6. The reaction times must be ob-
served!
Total reaction time = reaction time
MPA + reaction time ame detec-
tor
The reaction time of the MPA is < 1 s
7. The EMC regulations must be
observed (EN 298). The entire
system must not represent inad-
missible emissions.
8. The MPA51xx is not decoupled.
The polarity of the MPA and the
ame detector must be strictly
observed.
9. Prior to use a ame sensor which
is not included in the list, please
contact DUNGS. DUNGS cannot
be held liable if the ame detector
and the automatic burner control
do not work orderly together.
Especially if the electromagnetic
behaviour is not according to the
regulations or if the time depend-
ent behaviour is not correct.
For a good ame detection the ame
signal has to be considered during
conguration of the burner.
The LED of the ame on the display
must not be ashing and the dis-
played signal in the VisionBox appli-
cation must have more than 40 digits.
