FAAST LT FAULT CODES
FAULT /
ALERT
SHORT NAME
DESCRIPTION
SA
LB
NOTES
Fault [F001]
CONFIGURATION
FAULT
Device configuration data
is not available .
X
X
This fault is given when at power-on EEPROM data is
not available (device cannot read its EEPROM) or
when data is wrong (bad checksum) or when data is
invalid (not in correct range) . When device is in
WRONG CONFIGURATION fault it enters
automatically into maintenance mode, waits for USB
connection and activates only general fault relay .
Note that in WRONG CONFIGURATION, if RESET is
pressed for 2 seconds, device will restart . Normal key
functions are not available .
Fault [F002]
EEPROM FAULT
Device is unable to access
its EEPROM .
X X
Fault [F004]
EXTERNAL INPUT
FAULT
Device external line input
fault .
X
X
Given when external input is configured to give fault
when not in normal state
Fault [F005]
ULTRASONIC
CIRCUIT FAULT
CH1
The ultrasonic circuit of
channel 1 is not working
properly .
X X
Fault [F006]
SOUNDER FAULT
CH1
The sounder 1 output is in
short or open circuit .
X

Please check the sounder circuit and the 47K end of
line resistor .
Fault [F007]
SENSOR
COMMUNICATION
FAULT S1
Error in communication
with sensor 1 .
X
X
In SA variant, it is given when sensor doesn’t answer
to FAAST LT unit or sensor reports low chamber
signal .
In LB, sensor alarm mode, it is given when sensor
remote output is OFF for configured timeout .
Fault [F008]
SENSOR

Fault [F012]
LOW FLOW FAULT
CH1
Channel 1 flow is below
the configured limit .
X
X
User can configure a specific delay between fault
condition and fault indication (0-240 s)
Fault [F013]
HIGH FLOW FAULT
CH1
Channel 1 flow is over the
configured limit .
X
X
User can configure a specific delay between fault
condition and fault indication (0-240 s)
Fault [F014]
ULTRASONIC
CIRCUIT FAULT
CH2
The ultrasonic circuit of
channel 2 is not working
properly .
X X
Fault [F015]
SOUNDER FAULT
CH2
The sounder 2 output is in
short or open circuit .
X
X
Please check the sounder circuit and the 47K end of
line resistor .
Fault [F016]
SENSOR
COMMUNICATION
FAULT S2
Error in communication
with sensor 2 .
X
X
In SA variant, it is given when sensor doesn’t answer
to FAAST LT unit or sensor reports low chamber
signal .
In LB, sensor alarm mode, it is given when sensor
remote output is OFF for configured timeout .
Fault [F017]
SENSOR
INITIALIZATION
FAULT S2

ALERT
Device temperature is
over the limit .
X X
SA denotes a Stand Alone unit
LB is a Loop Based (addressable) unit
An
x
denotes applicable to either SA, LB or both .
