IN ACCORDANCE WITH STANDARD EN 298

SCHEDA VISUALIZZATRICE .

The CF5 flame control is supplied

together with the additional display card

STK035. This offers the opportunity to

control the functionality of the equipment

in a more effective and immediate way.

This is made possible by the four LEDs for

displaying the flame level, the LED for

controlling the safety systems and the

LED for remote unlocking. The latter also

remains slightly lit when the main switch is

in position 0 to indicate presence of

voltage (N.B. can only be used by

authorized personnel keeping under

control the burner to be turned on).

MONTAGGIO .

-Mounting position as desired

-Assembly of the fixed rear part,

through 4 preformed holes to be

removed by pressure.

- Prepared for pipe connection collars

- CF5 can be supplied already wired,

otherwise make the necessary holes

only in the rear part and use cable

glands that guarantee at least the

same degree of IP protection declared.

CAVI CONSIGLIATI .

IONIZATION: Maximum length 10 meters with

recommended section 1 mm. Laying away from

sources of disturbance, avoid external electrical

influences.

IGNITION: as specified by the manufacturer of the

ignition transformer. Recommended conductor

diameter 1mm. Lay individually away from metal

parts.

CABLAGGIO .

Remove power from the system.

In three-phase systems, use the same phase on

the inputs. There must be no voltage present in the

output for the solenoid valve.

The enabling command of the CF5 that comes

from the safety sequence (all the main control

devices for safety purposes such as thermostats,

GASmin, GASmax, leakage control, prewash, etc.

...) must be voltage-free contacts.

The output voltage for the solenoid valve and the

ignition transformer (included if required) is the

same as the supply voltage.

The current max. for solenoid valve and ignition

transformer is 1A.

Alarm contacts max 1A 230Vac not protected by

internal fuse.

Make a good connection of the ground of CF5 to

the burner mass to ensure correct operation.

Partenza normale con fiamma

Riavvio dopo mancanza fiamma

MESSA IN SERVIZIO .

1. Open the gas valve.

2. Start the system.

3. Give power to the CF5.

4. Press the power button (green power

LED lights up).

5. Switch on the enable terminal to start

the ignition cycle.

6. Waiting time at the start of about 5sec.

7. After this time the CF5 will carry out the

ignition cycle. The gas solenoid valve

will be commanded and the discharge

will be carried out at the same time

(yellow discharge LED will light up). At

the end of the discharge the presence

of the flame will be checked.

8. In its presence, the equipment goes

into operation by turning on the green

detection LED and continuing to power

the solenoid Gas valve.

9. Otherwise CF5 will go into lockout (the

gas solenoid valve will be

disconnected, the alarm contact will

close and the red lock LED will light

up). To reset it and retry the boot it will

be necessary to switch it off and switch

it on again using the power button.

N.B. The terminl box should never be

used. This clamp has remote unlocking

functionality and must be used only by

authorized personnel, keeping the burner to be

re-ignited under strict control.

OPERATION CHECK .

1. Remove the detection plug during

operation.

2. CF5 will attempt to restart only once,

after which it will be shut down due to

an anomaly (the gas solenoid valve

will be disconnected, the alarm contact

will close and the red LED will light

up).

3. The burner flame must go out.

4. If a different operation should occur

check the wiring. This done if the

problem has not been resolved

disassemble the CF5 and send it to the

manufacturer for a complete overhaul.

After replacing the safety device, check its

operation:

- Close the general gas valve and check

that the appliance, after a few attempts,

does not start.

If the safety device works correctly and

the wiring is in order but the equipment

attempts to start the burner, send it to the

manufacturer for a check.
