DISPLAY STATUS DESCRIPTION
FLASHING
Lockout due to an error in the internal memory reading. The failure can be tem-
porary or final. The causes can be found in the incorrect connection to ground
of the instrument or of the connected ignition devices, in the missing suppres-
sion filter in the ignition electrode connector, or else in the strong electromagne-
tic disturbances in the atmosphere or in the power supply. If after an attempt to
reset the problem reoccurs, the instrument must be sent back to the manufac-
turer.
FLASHING
Lock out due if the ZSL gas valve limit switch signal is missing for more than 5
seconds prior to ignition or if the actual limit switch has not been released after
10 seconds following the ignition phase. The causes can be found in possible
incorrect wiring or in the adjustment of the limit switch of the valve.
FLASHING
Lockout due to missing communication with the optional card, if the presence of
the expansion card has been configured. The causes can be found in the incor-
rect programming or in a card failure; in the first case check the programming,
whilst in the second case if after an attempt to reset the problem reoccurs, the
instrument must be sent back to the manufacturer.
FLASHING
Lockout due to a short circuit in the internal command relay. If after an attempt
to reset the problem reoccurs, the instrument must be sent back to the manu-
facturer.
FIXED (1)
Malfunctioning due to the front button or the digital input button (if the reset/stop
function from remote is on) that are blocked as if pressed during the auto dia-
gnosis of the instrument. The causes can be found in the connection and con-
trol of the remote reset, in the possible absence of the RC filter, or front button
failure. To reset the alarm, cut off the power to the instrument for a few seconds.
FIXED (1)
Malfunctioning due to memory corruption or a failure in the safety system. The
failure can be temporary or final. The causes can be found in the incorrect
ground connection of the instrument or of the connected devices, in the missing
suppression filter in the ignition electrode connector, or else in the strong elec-
tromagnetic disturbances in the atmosphere or in the power supply. To reset the
alarm, cut off the power to the instrument for a few seconds. If the problem
reoccurs, the instrument must be sent back to the manufacturer.
FIXED (1)
Malfunctioning due to a short circuit in the internal safety relay. To reset the
alarm, cut off the power to the instrument for a few seconds. If the problem
reoccurs, the instrument must be sent back to the manufacturer.
FIXED (1)
Malfunctioning due to a short circuit between the pins and the microprocessor.
If the problem reoccurs, the instrument must be sent back to the manufacturer.
FIXED (1)
Malfunctioning due to a gap in the program. The causes can be found in the
incorrect ground connection of the instrument or of the connected ignition devi-
ces, in the missing suppression filter in the ignition electrode connector, or else
in the strong electromagnetic disturbances in the atmosphere or in the power
supply. To reset the alarm, cut off the power to the instrument for a few seconds.
If the problem reoccurs, the instrument must be sent back to the manufacture
FLASHING
DISPLAY
AND BARGRAPH
Mlafunctioning due to excessive ambient temperature that does not allow the
instrument to work. When this malfunctioning occurs the instrument continues
to switch on and off displaying only the beginning of the auto diagnosis phase.
(1) (1) The indication of these failures or lockout conditions starts flashing when power is supplied again, indicating
that alarm reset is possible.
