Fig. 3 - Simplified Drawing

Figure 3, Simplified Drawing, gives a quick idea of how the 5th mirror and iodine cell insert/retract stages work. For safety, the programmers asked to have the AC power to the mirror and iodine cell segregated from the mirror cover. This allows the software to interlock the mirror cover from the mirror and cell so that it can't open or close until the program applies power to the control modules. The signals that do this are DO41 (Digital Out 41) and DO42. DO41 turns on the mirror cover relay rack and DO42 turns on the 5th mirror and iodine cell relay rack. Obviously, these signals are levels whereas the remaining signals must be applied as pulses. Each of the other outputs are wired to pulse type air solenoids which are plumbed to Bimba cylinders. In each case, the cylinder is activated to either extend or retract depentent on which coil of the solenoid was last pulsed. The

Table 3.

Table 3 shows the connections between J2 (axes A - D) and the rear stage connector. This consists of the HOME, FORWARD LIMIT, REVERSE LIMIT, and the Error signals. Note that the ERROR signal is generated by the Applied Motion ST5-S stepper driver box. If this is asserted a technician should physically look at the stage to see if there is a problem such as blown fuse. If nothing is obvious it may be useful to power cycle the drive box.

Table 5.

Table 5 show the wiring for the FINE fiducials between the various Galil connectors and the stage connectors. Note that the FINE fiducial signal is referenced to the Galil's internal +5V supply. Also, the signal is used to trip the stage index input but is derived from Hall-effect sensor mounted to the shaft of the stage stepper motor. Only the Grating Tilt and Slit stages incorporate a FINE fiducial signal/sensor.
