Check mode function

By the reset push button on the main panel of the control flame the
check mode functions are available (prepurging, ignition, 1st safety
time and 2nd safety time).
The CHECK MODE is designed to facilitate the checking of the
working phase of the burner.
This function is particularly useful during the burner first
commissioning or during maintenance.
To enable the check mode function:

keep the reset button pressed, see chapter 8 for more details,
for at least 3 seconds, the status LED changes from green to
yellow to signal that the control device is in check mode;

the control device locks out during pre-purging, after a timeout
of max 30 minutes the flame control will automatically exit the
check mode function;

check mode has a 2 minute timeout during the 2nd safety time.
When the time out is expired, the flame control goes back to the
normal operating status;

check mode has a 2 minute timeout during the MTFI status.
When the time out is expired, the flame control goes back to the
normal operating status;

during the check mode 1st or 2nd safety time, the flame signal
level can be indicated by the 5 central LEDS on the flame
control central panel, which turn on proportionally. 
Each lit LED (starting from the flame LED) represents 20% of
the signal power.
To exit the check mode function, press the reset button; the
flame control will go back to the normal operating mode.

7.3

Flame control lock-out or emergency stop condition

The RFGO control device can be locked (emergency stop) at any
time during the operating cycle and unlocked when already locked
(lock-out) by simply pressing the key on the front panel or by
means of the terminal T21 on the support base.

LED indicator and special function

Fan

It turns on when the fan motor is powered (T6) and blinks when RUN/CHECK switch is set to

“CHECK” during damper movement phases, PTFI AND MTFI.

Open

damper

It blinks when the air damper is moving towards the maximum opening position until the position-

reached feedback sent by the servomotor is received, then it stays steadily on for the time set by

the flame control.

Closed

damper

If blinks when the air damper is moving towards the minimum opening position until the position-

reached feedback sent by the servomotor is received, then it stays steadily on until the end of the

pre-purging time.

Auto

It indicates that the burner is ready for the output modulation. 

Ignition

It blinks during the ignition phase (1st safety time) and stays steadily on during the MTFI.

Flame

It blinks during the first safety time and stays steadily on if the flame detection has been correctly

performed.

Alarm

It turns on in red when a lock-out condition occurs.
Together with the other indicators, it indicates the type of fault during the lock-out phase.

Together with the other LEDs, it indicates the operating status during the normal cycle.
