4.3. Reset and Fault index
In case of lockout, the modulation PCB of the heater allows
the operator to identify about thirty different causes of lockouts
with a code. This makes it possible to manage each event very
accurately.
To reset the Fault and unlock the heater, simply press the two
LDC panel arrow keys (
↑ and ↓ )
simultaneously for at least 3
seconds or operate one of the remote controls provided, if any.
Lockouts may be remotely controlled by using:
•
the digital input ID4-IDC4 - button N.O.;
•
the Smart Web/Easy - optional;
•
the ModBus protocol.
The Faults are classified according to the type of error; the most
common and easier to sort out by user are:
F1x
these faults are caused by the burner failed ignition;
they all require a manual reset.
F20
heater safety thermostat lockout; this fault must be
manually reset.
F22
opening of the safety thermostat of the heater at start-
up, due to a fault or to a temperature below -20°C.
F21
jumper missing across terminals ID1 and IDC1.
F3x
lockouts caused by faults of the fume extractor.
F4x
lockouts caused by an error or by a missing temperature
probe; they must be sorted out by the Service Centre.
F51
the temperature of the air supplied has exceeded the
upper limit set in parameter TH1; as the temperature drops, the
lockout will sort itself out; manual reset is not required.
F60
on the LCD panel only, the heater is connected to a
Smart Web or Easy but does not communicate. When commu-
nication is restored, the lockout condition will disappear; manual
reset is not required.
If ignition fails, the flame monitoring system reattempts ignition
four times. After four failed attempts, it will lock out and will
display the code F10.
If the flame monitoring equipment has locked out (codes from
F10 to F20), it can be reset it by using the button on the equip
-
ment itself. This lockout is shown by a LED that lights up on
the equipment.
The list and meanings of all lockout codes, with any relevant
cause, are shown in the FAULT table in Paragraph 5.7 "Analysis
of lockouts - faults".
WARNING: The flame monitoring equipment memorises
the number of manual resets that are performed during
its lifetime. In case of five resets performed in a period
of 15 minutes, without a flame being ignited and detect
-
ed, the equipment will go into a "timed" lockout (F13).
In this case, it is required to wait another 15 minutes
before resetting it again. Press the reset button on the
equipment to immediately reset this lockout condition.
NOTE: SHOULD THE SAFETY THERMOSTAT (STB) BE
“OPEN” BEFORE THE START-UP CYCLE IS STARTED,
F22 LOCKOUT IS SIGNALLED. THIS CAN OCCUR, FOR
EXAMPLE, IN THE PRESENCE OF LOW TEMPERATURES
