5.0 ABA Operation
The door open warning indicator in the header bar of the main menu screen (see Fig
35.) will appear red if the door is open or the lock is not properly fastened.
Fig 35 - Screen-view: Door Open Warning
The door locked indicator (see fig 34.) shows that the door is locked after a test has
started.
If either or both of the shock risk warning lamps (see Fig 34.) light up when
the door is open,
do not load or remove a sample. Samples may be
removed if the power is first turned ‘Off’. Contact a Carbolite Gero
approved service engineer immediately
.
The door lock is automatically controlled but has an override key, the lock is on the right
hand side of the ABA case. Ensure that the key override has been correctly left in the
‘locked’ position after installation.
If the door lock is unlocked when a test is started the test will fail to start and a
continuous warning tone will be emitted along with a warning screen indicating that “The
door has failed to lock”. The door must be locked before the test can be started.
If the door is unlocked during a test a continuous warning tone will be emitted along
with a warning screen indicating that “The door should be closed and locked
immediately”. This warning should not be ignored; failure to do so may result in serious
injury. The test will continue when the door is once again locked.
Door Lock will operate under the following conditions:
l
when the ABA is disconnected from the power supply the door is locked
l
when the illuminated furnace power switch (see Fig 33.) is switched on the door nor-
mally unlocks
l
If however there has been an interruption in an operating test, for example by a
power cut or the ABA being switched off, the door lock remains locked when the ABA
is once again switched on. To unlock the door, the test must be cancelled using the
test cancel code (see section 7.7) .
l
at the start of a test the door locks automatically
l
at the end of a test the door unlocks automatically

General Operating Notes
Heating element life is shortened by use at temperatures close to maximum. Do not
leave the ABA at high temperatures when not required. The maximum temperature for
the main chamber is 750 °C (1380 °F) and is factory set for the after burner at 900 °C
(1652 °F)
The chimney and should always be correctly fitted and unobstructed (see Fig 13.).
see section 20.0 for information about maintenance.
