Red LED
Burning indicator and after-cooling
In the heating phase, when the burning indicator has
turned on during glowing or ignition, the red LED light
will illuminate at that point and remain illuminated
continously. The LED light will react without any delay
if the burning indicator shuts off. The actual
malfunction that caused the burning indicator to shut
off will be locked 5 seconds after the burning
indicator fails to work.
During after-cooling, the LED light will begin to
uniformly flash once the burning indication limit has
been broken.
The LED will flash on and off for a duration of 0.25
seconds. After-cooling lasts for approximately five
minutes.
Flashing due to over-heating
During the heating phase, when the alarm indicating
over-heating has locked as the result of a 5-second
over-heating situation, the red LED light will
uniformly flash. The LED will flash on and off for a
duration of 0.25 seconds. The LED light will shut off
5 minutes after the start of the flashing due to over-
heating.
Flashing light after the flashing due to a malfunction
When the flashing light due to intial test
malfunctions, as presented in the “Initial testing”
section, has lasted 5 minutes, the yellow LED light
will shut off and the red LED will begin to flash at
intervals of 30 seconds. Each flash during the 30
seconds lasts 0.125 seconds.
Third attempt to start the device
After two unsuccessful attempts to start the device,
the third attempt will lock it. In this case all LEDs will
begin to flash at a quick pace. The LEDs flash on
and off for a duration of 0.125 seconds.
Incorrect device parameters
If the device’s parameters are not set within the
permitted range of values at the point of start-up,
then the device will not start. However, the attempt to
start the device counts towards one start-up. All
LEDs will begin to flash in a circulating pattern; each
LED light will be on for a duration of 0.125 seconds.
All LED lights shut off for a duration of 0.125 seconds
between the time the first LED light shuts off and
another LED turns on. The LEDs circulate in the
following order: the yellow LED light and the red LED
light. During normal use, incorrect device parameters
should not occur in the device’s memory because the
XP Link terminal programme does not allow users to
enter incorrect parameters into the device’s memory.
Testing phase
The red LED light will be on during the testing phase
when the voltage measured on the T4 circuit
exceeds the 5 mV threshold. Correspondingly, the
LED will shut off when the measured value drops
under 5 mV.
