If you experience intermittent shut downs on the Intellisys equipped units,
indicated by the appearance of all 8888’s or-01-in the display window, check the
female connector on the gray ribbon.
We have learned that this connector may not be making a good contact with the
male pins on the interface boards.
To correct the problem, remove the female connector from the interface board,
look into the connector holes, if any of the contactors are depressed or appear
not to be making a good contact follow this procedure to effect the repair.
1. Remove the gray ribbon cable connector from the interface board.
-13- -14-
MESSAGE -12- INCORRECT COMPRESSOR ROTATION
Generally this fault will only occur during initial start up where the operator has
connected the cables wrong so that the compressor is being driven backwards.
Check the main incoming and power leads to insure that they are correct.
In earlier versions the controller will try to read a positive 10 psig sump pressure
in the first 3 seconds of operation. If it does not see this pressure it will assume
the unit is rotating backwards and can not develop pressure.
This condition can also exist when the flexible tubing attached to the line sump
solenoid is not inserted into the fittings completely and a small air leak exists.
Foreign material inside the solenoid valve orifices can also prevent a pressure
build up and the fault will occur.
Refer to the Intellisys Field Service Sheet No. 9.
Certain SSR 10-40 units may not develop adequate sump pressure of 10 psi (or
more) within 3 seconds of a manual start up. When this happens the unit shuts
down and indicates -12- (reverse rotation) on the display even though rotation
is correct.
To help alleviate this potential situation, we are revising the logic within the
Intellisys to look for a positive pressure within 3 seconds of start up. This will
eliminate the nuisance shutdown on -12- in these instances.
To secure this new revision level Intellisys Controller, order Kit No. 39679097.
This is for a factory re-manufactured controller and should be used when making
warranty repairs. We also have the capability of programming into the controller
appropriate load and unload hours to match units operating in the field. Specify
this requirement with your order if it is an important consideration.
Keep in mind that the parts manual also lists a new controller, P/N 39786470
order Kit No. 39668793. It will also have the new software feature described
above, but with zero hours running time. When making field repairs, it is
necessary to order gasket P/N 39786413. (Included in 39679097 and 39668793
Kits)
An order must be placed on Davidson for these parts, and the controller will be
shipped out of Davidson.
Units shipped after January 2, 1990 will have the reverse rotation revision
described above. Units manufactured prior to this date will not have the feature
described.
LOSS OF ELECTRICAL POWER
8888's
If this happens all 8888’s will appear in the display. This occurs when the
electrical power is interrupted for 250 milliseconds, which is equivalent to 15
cycles of electrical power. A conventional volt meter can not respond quickly
enough to detect this. However, the Intellisys can.
"Intellisys made after August 31, 1990 (Rev 9.0) go to 'ø' ready to start."
5. Make sure the latch is bent back
to the original position.
2. Identify the connector that is not
making good contact with the in-
terface connector pin.
4. The socket will slide out of the
plastic housing.
3. Remove the connector socket by
pressing on the latch while pulling
on the wire.
