No Indication or false indication of the operating state _________________________
After having switched on the main switch (4), the
autoclave shows its state of process by the following
indicators:
Door closed and locked:
Lamp "MAIN" lights,
Lamp "READY" blinks (if apparatus is still cold),
Lamp "READY" lights (if apparatus is pre-heated),
Lamp "WATER" lights (if there is lack of water).
Door unlocked:
Lamp "MAIN" lights,
Lamp "DOOR" lights,
Lamp "READY" blinks (if apparatus is still cold),
Lamp "READY" lights (if apparatus is pre-heated),
Lamp "WATER" lights (if there is lack of water).
If no indication of any light:
Is the autoclave plugged in?
Is there current in the socket? When switching the
main switch of the autoclave, lamp
„
MAIN“ must
come on.
If power is available to the autoclave, and if the
„
MAIN“ power switch (4) is switched on, but if no
signal is provided, then it is possible that the main
fuse in the autoclave is defective.
You must notify the MELAG Customer Service
Department.
In case of different indication:
Switch off main switch and switch it on again after
10 seconds.
If -- despite attempting the measures described
above -- the autoclave is still not in proper
operational status, as would be indicated by the
proper lamp signals given above, there is probably
an electrical defect within the autoclave. You must
notify the MELAG Customer Service Department. If
the electronic circuit board becomes dirty -- for
example, if disinfecting agent enters the device
through the forward vent slots -- then it may be
cleaned with methylated alcohol (C
2
H
6
O).
7.2
Lamp
„
READY“ does not light continuously__________________________________
If lamp "READY" blinks more than 20 minutes after
having turned on the main switch,
and the chamber
is still hot
, you have previously changed from
sterilization to disinfection program so that the
autoclave is still cooling down to pre-heat
temperature for disinfection (see 1.3). This can take
up to 45 minutes.
If the
„
READY“ lamp (11) flashes more than
20 minutes
while the chamber is cold
and no fault
has been signalled, the temperature sensor of the
preheating system is defective. You must notify the
MELAG Customer Service Department.
7.3
Impossible to start a program______________________________________________
Preheat phase / cool-down phase
During the following phases, it is not possible to start
a program:
•
During the approx. 10...15-min.
preheating
phase
(only once, after first switching on the
autoclave)
•
During the 5-minute
reheating phase
when
switching from the disinfection to the sterilization
program
•
During the
cool-down phase
when switching
from the sterilzation to the disinfection program.
During one of these phases, the lamp
„
READY“ will
glow. The operator must wait until the end of the
preheat, reheating or cool-down phase.
Door contact
A program start is only possible with the sliding door
closed and locked. Lamp "DOOR" will go out when
the sliding door is closed and completely locked.
Check that the door has been pushed to the end.
If the lamp
„
DOOR“ (8) does not go out through the
door has been correctly locked by a quarter turn,
then the contact has not been correctly set, or it has
been damaged by violent sliding of the door in its
locked position (the pushing rod has been bent in
the door guide).
You must notify the MELAG Service Department
The contact must probably be adjusted by removing
the nut of the microswitch and readjusting the
contact position inside the apparatus (while the
autoclave is hot).
If the door contact rod is bent, the microswitch must
first be removed, and then the contact rod must be
straightened. Then the microswitch must be installed
again (with the round side upward), and the door
contact must be adjusted again (see above).
Lack of water
If the signal lamp "WATER" lights, there is not
enough water in the storage tank so that it is not
possible to start a program.
The water storage tank has to be filled (see chapter
3.3).
If the lamp does not go out when the reservoir is
filled to the lower edge of its trapezi-form inlet, a
service engineer must check the water level switch
of the container.
It may be possible to trigger the switching process
for the water-level indicator switch by tapping lightly
against the autoclave or against the water storage
tank.
Program still running
When a process is running (lamp "RUNNING" lights
or blinks) or the sliding door has not been opened
yet after a completed process (lamp "END" is still
on), it is not possible to start a new process. Wait
until the process is over and open the sliding door.
Note:
If the "START"-button is operated in one of the
above cases, you will hear a beep for 2 seconds
because of misoperation.
