ERROR MESSAGES

If an abnormal condition is detected by the unit's Self-diagnostic System, the Display Panel shows one of
the following error messages:
MESSAGE
BOILING TIME OUT
(No change in vapour tempera-
ture was detected within the set
time limit, usually 45 minutes)
READY TIME OUT
RESET OCCURRED
CONDSR OVER-HEAT
CHECK FAN
CHK HEATER FUSES
WARNING! VERY IMPORTANT! IF TRIAC IS FAULTY, DISCONTINUE USE IMMEDIATELY!
CHK HEATER TRIAC
POSSIBLE CAUSE
• Boiling did not occur within the
set time limit because the dirty
solvent mixture is too contami-
nated
• Blockage in the solvent fl ow
path, most likely with leakage of
solvent at the lid
Recycling was not completed
within 9 hours and/or dirty sol-
vent remains in the Tank.
The heater has stopped and
the computer has reset due to
a power interruption or drop in
voltage.
Over-heating occurred at the
Condenser.
Appears 10 min after the mes-
sage above if the problem is
a loose fan blade, blown fuse
(F3 or F4) or other fan-related
problem. Also appears if the
condenser is dirty.
Appears if the computer does not
detect a rise in tank temperature
after 15 minutes.
Short circuit in the TRIAC (a
switching transistor that controls
heater power, located on the
Power Control Board).

ACTION
• Run SETUP, raise the Temper-
ature Set Point and repeat the
recycling operation. See Trouble-
shooting Guide ("Dirty solvent
remains in Distillation Tank after
recycling').
• Follow Sevice Procedure 2
If dirty solvent remains in the
Tank, see the Troubleshooting
Guide.
Press the "STOP" button to
restore the unit to the beginning
of a new cycle. The display will
read: "READY-SP = XXX° C".
The Condenser is dirty or the
Fan stopped for another reason
(see below). Clean the Con-
denser. When the Fan Motor has
recovered (4-5 min), this mes-
sage will disappear and normal
operation will resume.
Clean the Condenser. Run TEST
MODE to check for defective fan
motor. If necessary, check for a
loose fan blade or blown fuse
(see next section).
There may be a short circuit in
the Heater circuit causing fuse
F3 and/or F4 to blow or poor
electrical contact in the Heater
circuit. Check circuit condition
with a tester. Correct as required.
To confi rm, fi rst disconnect and
re-connect the power supply. If
the Distillation Tank becomes hot
to the touch and both the Heat
Light and the Fan Light are off ,
the TRIAC is defective. Discon-
nect the power supply imme-
diately and do not use again
until the Power Control Board
has been replaced.
