XIII. TROUBLE SHOOTING
1. Check for the correct style of paper in the printer. (It must use
Thermal paper 2 1/4 inch roll).
2. Check the paper tension bar (located under the bottom of print
head). Tension Bar must be in the up position to allow it to feed
paper thru.
3. Check for paper jam.
4. Check the cutting wheel on the printer head. (The wheel must be
all the way to the right in the ready position.)
5. Check the wiring from the relay board to the control board and
the wires from the control to the printer.
6. Paper must be installed correctly. (It must come off the top of the
roll with the treated side up as it passes thru the print head.)
7. If the unit has two printers you might, try to swap the two printers
to help confirm the printer is not repairable.
8. Should the Printer causes the unit to have a power interruption,
while asking to print the label, the issue will be with the Smart
Chill Board and must be changed out with a version 1.12 or higher
to correct the problem.
1. The Box Temperature has exceeded 160 . All fans, compressors
and heaters turn off.
2. The Refrigeration Systems have failed to come on to cool the box.
3. The Cabinet Air Sensor could be bad and could be reading higher
than 160 and will cause this Error message.
4. The power must be turned off and then back on to reset the
control.
1. Check all operation sensors. (Cabinet air senor, Maintenance coil
sensor, and Blast Chill coil sensor).
2. Check the refrigeration systems for proper operation. The lack of
either refrigeration system will cause the chill time to run longer.
3. Check the blower motors for proper operation. Observe the
Blower Motor housing & blower wheels for any deformation.
4. Check the operation of the unit. If the control was in a "By Temp
or By Time" mode for more than six hours the unit will shut down
and the only way to make it come back on is to turn off the power
and then restart the unit.
1. Both Defrost Sensors did not achieve defrost termination
temperature (50 ).
2. Go to program 75 until you reach the Def/coil button. Press this
button and observe the temperature of both sensors. If one or
both read strange or open circuit, the bad sensor should be
changed out.
3. Check the Thermal fuse, located near the evaporator coil. If it is
open the heater will not come on to raise the temperature past the
termination point.
4. Go to program "85" (see manual & scroll thru until you see the
defrost time). The length of defrost should be set to 40 min.
