Allen-Bradley SLC-150 Controllers are used on many Besser machines. Since 1988 most
Besser Concrete Products Machines, SF-7 Cubers, BTO's and LSC-40 Crawlers have SLC-150 controllers
inside the control panel. The PC Run Light, LED must be illuminated for the controller to operate.
The SLC-150 may drop out of Run during lightning storms, welding on the machine, amperage surges,
or voltage fluctuations, either up or down. If the SLC-150 drops out of
Run, the Run LED, will go out and usually an error message will be displayed on a T CAT or hand held programmer. If you are
repeatedly dropping out of Run, contact the Besser Technical Service Department for assistance.
Figure 1 -
Allen-Bradley SLC-150 Controller
In most cases, a hand held programmer, Besser Part No. 112778 is required to get back into the
Run Mode. If you do not have this unit, follow Part 1 on page 2.

WARNING Have all personnel remain clear of the controller equipment when power is applied.
Intermittent and sudden unexpected machine motion could occur and result in injury.
Have someone ready to operate an emergency stop switch in case it becomes necessary to
shut off power to the controller equipment. See NFPA 70E Part II for additional guidelines
for safety related work practices. |

PART 1
STEPS TO GET INTO THE RUN MODE WITHOUT A HAND HELD PROGRAMMER.
- Make sure the Auto/Man Switch is in the Auto
position.
- Turn the power off for ten seconds - then turn it
back on. If the RUN LIGHT is still not
ON, proceed to Step 3.
- Download your EEPROM chip. (Besser No.
112668)
a.) Turn the power OFF.
b.) Plug the correct EEPROM chip into the SLC-150.
c.) With the Auto/Man Switch in Auto, turn the
power ON for ten seconds.
d.) Turn the power OFF. Remove the EEPROM chip.
e.) Turn the power back ON.
- If you are still not in RUN MODE, you
must use a Hand Held Programmer. Proceed to Part 2.

Programmer
PART 2
USING A HAND HELD PROGRAMMER - QUICK METHOD.
- With the pane power OFF, plug the hand held programmer into the front of the SLC-150. (If you
have a T CAT, it will have to be unplugged first).
- Turn the power ON at the panel and on the programmer.
- a.) After 5 seconds, see if an error code,
E and a number following it, like
E06, is shown in the data area. If and error code is displayed, press the
CANCEL CMD, button on the the programmer.
Then continue to 3 b.
b.) When an abbreviation for one of the 9 modes and the mode # is displayed, press
mode, 3, ENTER. Mode 3 is RUN and entering mode 3 will put the SLC-150 back into
RUN. NOTE: If you followed part 2 above, but the machine will still not
function normally follow
the steps in Part 3.
PART 3
USING THE HAND HELD PROGRAMMER AND "DOWNLOADING" THE CHIP.
- All the steps in Part 2 have been completed with the programmer plugged in, the
RUN light may or may not be on.
- Make sure the programmed EEPROM chip is not plugged into the SLC-150.
NOTE: Always make sure you have a programmed chip on hand before doing step 3 of
Part 3.
- Press MODE, 1, ENTER, when it asks
SURE? on the programmer, press
ENTER again. This will clear the program in the SLC-150.
- Press, MODE, 3, ENTER, on the programmer to get the
RUN light back on.
- Download your EEPROM chip by following the
Part 1 - Step 3 instructions.
NOTE: Make sure the Run light is on before downloading the chip.
