2.
Check for 5 Volts DC between terminals 2 and 5 on BTS-3 terminal strip
of the Starter Interface Board.
If voltage is not available at this point, a faulty Starter Interface Board is
indicated and must be replaced.
3.
Check for 5 Volts DC between terminals 2 and 3 on BTS-3 terminal strip
of the Starter Interface Board when the inlet valve is closed.
If 5 Volts DC is not present, check to determine if the tab on the coupling
is actually engaging the closed limit switch on the Stepper Limit board.
If the switch is engaged, check for a loose wire or faulty Stepper Limit
board.
4.
Check for 5 Volts DC between terminals 2 and 4 on BTS-3 terminal strip
of the Starter Interface Board when the inlet valve is fully open.
If 5 Volts DC is not present, inspect areas listed in previous checkpoint

PROCEDURE FOR SETTING THE PROPER BLOWDOWN
SEQUENCE ON SSR INTELLISYS MACHINES
The proper blowdown sequence depends upon the correct unloaded position of
the inlet valve. Loss of unloaded inlet valve position will only result in a longer
blowdown sequence than expected. The following are conditions that will cause
the Intellisys to lose control of the correct unloaded inlet valve position. (2)
alarms will make it dumb high vacuum, los amps or calibration of a transducer.
A. Calibration, (recalibration) of any pressure transducer.
B. High inlet vacuum shutdown.
C. Low sump pressure.
D. Temporary, programmed loss of unloaded inlet valve position occurs
every 500 hours of loaded operation. Recovery from this condition is
automatic and will occur without operator attention.
To establish the correct inlet valve position, perform the following steps:
1. Calibrate 1 AVPT transducer as follows:
a. Power to unit must be shut off.
b. Vent all pressure from the unit.
c. Turn on incoming power to the unit ... you will see the “Power On” light,
the small lightning shaped “Power” light, the small, “Unload” light and
the words, “Checking Machine” which will change automatically to
“Ready to Start”.
d. Press “Set” once ... then you will see the words “Ready To Start”
change to “Press Set Chg Values” and/or “Press Test - Light Ck”.
These two sets of words will flash back and forth about every 3
seconds.
Also, a small white light over the “Set” button and a red “Test” light will
appear.
e. Press the “Down” arrow of the “Display Select” and the Mod/ACS
button at the same time once.
f.
You should see the words “Scroll for Sensor” and 2 red arrows
appear.
g. Press the “Down” red arrow and you will see two sets of words ...
“Sensor 1 AVPT” and “Inlet Vacuum” flash back and forth on the
display about every three seconds.
h. Press “Set” ... and “Sensor 1AVPT” will blink twice and lock in the
transducer calibration. No further transducer calibration is necessary
to finish this procedure.
i.
Now wait thirty seconds and the panel will automatically default back
to “Checking Machine” and then to “Ready To Start”.
2. Start the machine and allow it to warm the injected coolant temperature
to at least 120 Deg. F.
3. Load the machine in either mode - on/off line or Mod/ACS.
4. Manually unload and observe the sump pressure, allowing sufficient
time, (approx. 5 min.) for the sump pressure to drop into the range of 23
- 34 PSI.
5. When the sump pressure falls into the range of 24 - 33 PSI, and stabilizes
for 7 to 10 seconds, load the machine.
6. Unload again and observe the sump pressure. It should fall to 24 - 33 PSI
range, in less time than observed in step 4. (Approximately 3 minutes.)
7. If the sump pressure does not fall quickly into the 24 - 33 PSI range, stop
the unit and repeat steps 1-6.
NOTE: The sump pressure will stay between 45 - 50 PSI when the injected oil
temperature is below 120 Deg. F. when the unit is unloaded. (Unit must be
above 120 Deg. F. coolant temperature to perform the above procedure.)

50-200 HORSEPOWER
Procedure To Calibrate Transducers
1)
Vent all pressure from the unit.
2)
Turn on incoming power to unit...you should see...the big “Power-ON”
light, the small lightning shaped “Power” light, the small “Unload” light and
the words “Checking Machine” which then turns to “Ready-To-Start.”
