General Considerations - Honeywell S4560 Bedienungsanleitung

Wiring
CAUTION
Wiring must be in accordance with local regulations.
Never combine high tension wiring with other wiring.
 Use untinned receptacles for easier connection.
 Use leadwire which can withstand 105 _C ambient.
 Use leadwire which is proven against moisture.
 Wiring between automatic ignition control and spark
sensing electrode should have good quality insulation,
suitable for the temperatures encountered.
 Length of wiring for external components: 1 m max.
Wiring to automatic ignition controls (see fig. 1.)
1. Ground wire has large self inductance due to long length.
2. High tension wire has large capacitive coupling to other
wire
Results of 1. and 2. :
Sparks and flash over on PCB
Damage of PCB

Supply voltage polarity
WARNING
If automatic ignition control seems to operate normally
but does not detect ignition flame, check for right
polarity of power supply (line, neutral).
Spark gap
Refer to the appliance manufacturer's instructions for
recommended ignition electrode position.
Maximum allowable spark gap: 3.5 mm.
Checking flame current
 The minimum value should be 0.7 ←A.
 To check flame current connect a DC micro--Ampèremeter
between flame sensing wire and flame sensor rod.
 If flame current is insufficient check that flame sensing rod
is fully enveloped by the flame and that burner is reliable
grounded to automatic ignition control.
Checkout
After installation, set burner system in operation and observe
through a complete cycle to ensure that burner system
components function correctly.

GENERAL CONSIDERATIONS

The automatic ignition control should be externally fused.
The automatic ignition control contains no serviceable parts.
Any attempt of replacement of parts will affect the safety of
this device and is therefore not allowed.
High temperatures will affect product life.
When the automatic ignition control is built in an appliance,
the total protection must be IP 40 at least.
To ensure reliable long term operation, mount automatic
ignition control at a position in the appliance with a low
ambient temperature and a low radiation.
For safety a high limit thermostat must be connected in series
with the comfort controls to de--energize the automatic ignition
control in case of over temperature.
To suppress Radio Frequency Interference (RFI) the spark
electrode cabling should be mounted in a sufficient shielded
environment.
NOTE: Electrical rating of connected controls and air
proving switch should be appropriate for the load
that is switched by the automatic ignition control.
NOTE: The emission level in accordance with EN 55014
generated by the electronic ignition is in some
applications higher than allowed and need to be
checked.
Additional EMC filter may be needed.
