INSTALLATION AND CHECKOUT

Important

:

Before connecting the controller to
main supply, wait for at least one
hour.

:

Installer must be a trained
experienced service man.

:

Disconnect power supply to
prevent electrical shock and/or
equipment damage.

:

Before installing or replacing any
control check that type number is
correct for the application.

:

The appliance manufacturer’s
instructions should always be
followed when provided.
If such instructions are not
provided see fig. 3 and 4 for typical
systems.

:

Ensure combustion chamber is free
of gas before start up.

:

At the first start the automatic
ignition controller can be in lock
out; depress reset button to free
control.

:

Never open the upper part, which
includes the electronics

Mounting
The automatic ignition controller should
be mounted on a flat surface by means
of 2 screws in the mounting holes of the
subbase.

Mounting position
The automatic ignition controller
functions position independently and
such can be mounted in any position.

Spark gap
Refer to the appliance manufacturer’s
instructions for recommended ignition
electrode position.
Maximum allowable spark gap: 4 mm

Wiring

:

Wiring must be in accordance with
local regulations

:

Use leadwire which can withstand
105

E

C ambient.

:

Use leadwire which is proven against
moisture.

:

Wiring between automatic ignition
controller and spark sensing probe
should have good quality insulation,
suitable for the temperatures encoun-
tered.

Supply voltage polarity

Warning
If automatic ignition controller seems
to operate normally but does not
detect ignition flame, check for right
polarity of power supply (line,
neutral).

Checking flame current

:

The minimum value should be 1

µ

A.

:

To check flame current connect a DC
micro--Ampèremeter between flame
sensing wire and flame sensing rod.
(see fig. 1 and 2).

:

If flame current is insufficient, check
that:
-- proportion of flame touching the

grounded portion of the burner
is 3 to 4 times the proportion
enveloping the flame rod.

-- there is a good ground

connection to the controller.

Checkout
After installation, set burner system in
operation and observe through a
complete cycle to ensure that burner
system components function correctly.

See fig. 6 for sequence status LED’s

GENERAL CONSIDERATIONS

The automatic ignition controller should
be externally fused.
If, due to a short circuit, the internal
fuse is blown, the automatic ignition
controller must be repaired by
Honeywell.

When the automatic ignition controller
is built in an appliance, the total
protection must be IP 40 at least.

To ensure reliable long term operation,
mount automatic ignition controller at a

position in the appliance with a low
ambient temperature and a low thermal
radiation.

High temperatures will affect product
life negatively.

For safety a high limit thermostat must
be connected in series with the
thermostat to de--energize the
automatic ignition controller in case of
overtemperature.

To suppress Radio Frequency
Interference (RFI) the automatic ignition
controller including spark igniter
cabling should be mounted in sufficient
shielded environment.

Note
Electrical rating of connected controls
should be appropriate for the load
that is switched by the automatic
ignition controller.
