Digital input
function
Inhibited
The digital input of the device is not verified.
Reset / Stop
The digital input plays a double role: it leads the manual burner
shutoff in case the burner was ON or the burner restarts (if activated
for a time between 1 and 3 sec.) in case the burner was in lockout
stage.
Only stop
The digital input of the device is verified only with burner ON: when
activated leads the manual burner shutoff.
Only reset
The digital input of the device is verified only with burner in lockout
stage: if activated for a time between 1 and 3 sec it restarts the
burner.
Thermostat
The digital input has the thermostat function as the digital input
foreseen in the expansion card EXP-2: when the input is active, the
device ignites the burner, while when the input is disabled it
determines the burner shutoff. This setting is allowed only in case the
expansion card EXP-2 is not installed.
High
temperature
The digital input is used to activate the specific operation. This setting
is allowed only in compliance with EN746-2 and the activation of this
function is correlated to the parameter “High temperature function”.
Main burner
on / off
The digital input controls the 2
nd
gas stage as alternative to the serial
commands: with active input and 1
st
stage gas ON, the device allows
the ignition of the 2
nd
stage gas; while with input disabled it leads the
burner shutoff.
Air valve on /
off
The digital input controls the air valve as alternative to the serial
commands: with active input and 1
st
stage gas ON, the device allows
air valve opening; while with input disabled it leads the valve closure.
This function can be activated only when the air control is
discontinuous.
Lockout output
Stop / fault
The device activates the output signal in case of lockout, manual
shutoff or waiting for power supply (blinking display). The output is
disabled during the self-diagnosis phase.
Fault
The device activates the output signal only in case of lockout. The
output is disabled during the self-diagnosis phase, the manual shutoff
or waiting for power supply.
Local button
Remote
enable
The device doesn’t verify the push button because its control is
accomplished through serial communication. When the specific
command of request status is received, the device activates the
button with “Reset / Stop” function in order to allow the operation of
maintenance with local control.
Reset / stop
The push button plays a double role: if the burner is ON, it leads the
immediate shutoff, in case the burner is in lockout phase or is turned
OFF, if pressed for a time between 1 and 3 sec it restarts the burner.
Only stop
The device verifies the push button only in case of burner ON: when
pressed it leads the immediate burner shutoff.
Only reset
The device verifies the push button only in case the burner is in
lockout phase or is turned OFF: if pressed for a time between 1 and 3
sec it restarts the burner.
