After the loads are correctly set, turn the controller power OFF, and connect the high voltage
amplifier (HVA) power connectors to the bottom of the isolators.
4 System Initialization
4.1
Pre-Operational Self-Testing (POST)
After switching the controller power to ON, the controller will start its boot sequence; the system status
LED will light up red momentarily, then flash green for a few seconds. The controller will then perform a
number of internal self-tests to confirm system performance. The tests last approximately 60 seconds.
This includes a ~25 second warm-up time for stabilizing the analog filters and preamplifiers. Immediately
on power up, the following display will be shown:
T M C S T A C I S 2 1 0 0
P o w e r - U p S e l f T e s t
The system status LED will then change to steady amber as the unit goes through the POST. The
system is not ready for operation until the self-test is successfully completed.
The beginning of the system diagnostics (servo-loop) tests is indicated by the following message:

Prior to initial power-up, confirm the room environment is within a temperature
range of 10
°
C to 32
°
C (50
°
F to 90
°
F) and the dew point (humidity) is less than
20
°
C (68
°
F). Allow the STACIS
System to stabilize in temperature to prevent
condensation which could damage the actuators.
•
Ensure the difference in the displacement readings is kept to a minimum. For
example, on a symmetric payload supported by 4 isolators, the isolators along one
diagonal should not be loaded more than those on the opposite diagonal.
•
Adjusting the wedgemount on one isolator will change the load on all isolators.
•
If adequate adjustment cannot be achieved with the wedgemount, aluminum or
stainless steel shims, maximum one (1) per isolator, of approximately 10” x 10”
(254mm x 254mm) square should be added between the top of the isolator and the
interface plate/payload for the isolators with the less than desired loading.
•
Similarly, if the platform is not level as desired, shims must be used to change the
level. Measure the height of the platform at the corners to calculate the height
difference at each isolator. Compensate for the height difference by adding shims
on top of each isolator accordingly. This can be accomplished by slightly jacking
up one end of the platform to add shims to two isolators at a time. When complete,
allow 20-40 minutes for the internal elastomer mounts to settle
before re-
checking the level. Use 10” x 10” (254mm x 254mm) square shims, maximum one
per isolator
Mechanical Installation is complete.
