MANUAL - SOLVENT RECYCLERS - URS1600 SERIES, URS2000 SERIES & RI 80 Rev 2019-05
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
POSSIBLE CAUSE
ACTION
BOILING TIME OUT
(No change in vapour tempera-
ture was detected within the set
time limit, usually 45 minutes)
• 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
• 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
READY TIME OUT
Recycling was not completed
within 9 hours and/or dirty sol-
vent remains in the Tank.
If dirty solvent remains in the
Tank, see the Troubleshooting
Guide.
RESET OCCURRED
The heater has stopped and
the computer has reset due to
a power interruption or drop in
voltage.
Press the “STOP” button to
restore the unit to the beginning
of a new cycle. The display will
read: “READY-SP = XXX° C”.
CONDSR OVER-HEAT
Over-heating occurred at the
Condenser.
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.
CHECK FAN
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.
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).
CHK HEATER FUSES
Appears if the computer does not
detect a rise in tank temperature
after 15 minutes.
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.
WARNING! VERY IMPORTANT! IF TRIAC IS FAULTY, DISCONTINUE USE IMMEDIATELY!
CHK HEATER TRIAC
Short circuit in the TRIAC (a
switching transistor that controls
heater power, located on the
Power Control Board).
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.
