 +====== Gantry Translation Stage (GTS-1500) ======
  
 +===== INTRODUCTION =====
 +
 +
 +This manual outlines the operation of ASI’s GTS (Gantry Translation Stage) control system. ​ The GTS is a large, highly functional, computer-controlled stage system than can be configured in several different ways, depending upon the needs of the user.  The basic system consists of the control unit, the GTS X-Y-Z stage. ​
 +
 +This manual will describe the installation,​ operation, and programming for basic system components, plus sections for applicable options. ​ Please contact ASI regarding addition options if you wish to upgrade your system.
 +
 +==== Features and Capabilities of the GTS System ====
 +
 +
 +  *Standard system comes with X and Y travel distance 400mm x 400mm; Z travel distance 100mm
 +  *Closed-loop DC servomotor control of the X, Y, and Z axes for relatively precise positioning and highly repeatable focusing
 +  *Joystick control of X/Y position and Z range. ​
 +  *Wide dynamic speed range with adjustable trapezoidal move profiles
 +  *Multiple controller options from compact ergonomic tabletop control unit is 3½ x 13 x 7½ inches (9 x 33 x 19 cm) to standard Rack Mount
 +  *Back-lit LCD display shows X, Y, and Z coordinates,​ and Zoom Magnification
 +  *Smooth adjustable dual-range joystick control
 +  *Microprocessor control with RS232-C serial and USB communications
 +  *X, Y & Z axis Hall-effect limit sensors
 +  *Electronic torque limit on drives minimizes damage by runaway stage
 +  *“Zero,​” ​ "​Home,"​ and the programmable “Special Function” buttons .
 +
 + 
 +===== PACKING AND SHIPPING =====
 +
 +(Unpacking is the reverse of the procedure described below.)
 +
 +The GTS main assembly is fastened in place in the shipping container. ​ Foam padding is used to protect the rails and provides a platform for the attachments which are packed in separate boxes.
 + 
 +===== CONNECTING CABLES AND SET-UP =====
 +
 +==== Connecting the Cables ====
 +
 +Connect the cables referring to the following pictures if needed:
 +
 +1) X/Y cable with DB25 Connector to the GTS-2000 Controller.
 +
 +{{ gts_2_.jpg?​direct&​300 |}}  ​
 +{{ gts_3_.jpg?​direct&​300 |}}  ​
 +{{ gts_4_.jpg?​direct&​300 |}}
 +{{ gts_5_.jpg?​direct&​300 |}}
 +
 +2) Z cable with DB15 Connector to the GTS Controller. ​ Note: Some systems may have and optional F Axis for zoom capability.
 +

 +{{ gts_6_.jpg?​direct&​300 |}}
 +{{ gts_7_.jpg?​direct&​300 |}}  ​
 +{{ gts_8_.jpg?​direct&​300 |}}
 +
 +3) Attach the X,Y,& Z Connectors to the GTS as shown in the photo below.
 +
 +{{ gts_new_2_.png?​direct&​300 |}}
 +
 +4) Connect the 24V DC 2.7A power power supply to back of the  GTS controller.
 +
 +===== Limit Switches on the GTS =====
 +
 +There are three sets of limit switches on the GTS.  The limit switches for the Z (focus) axes are fixed and merely prevent the controller from driving the motors past the end of travel. ​ The limits for the X(gantry) and Y (tray) axis may be adjusted to limit the range of travel. ​ Each axis has  two magnets that slide on a rail slot which limit the range of motion by activating a hall effect sensor. ​ The limit switches are set at the factory to allow the longest range of travel. ​
 +
 +<WRAP center round important 60%>
 +WARNING!: Be careful when adjusting the limit switches, if you move the switch past the sensor, you can crash the axis into the end of travel – this can cause damage that may need to be sent in for repair. ​  The current limit protection will protect the motors – but will not cut off the motor voltage till after mechanical contact has already occurred
 +</​WRAP>​
 +
 +==== Adjusting the Y Limit Switches ====
 +
 +
 +To adjust the Y Limit switches –locate the two limit switches on the  Y(tray) axis.    ​
 +
 +{{ gts_new_3_.png?​direct&​300 |}}
 +
 +{{ gts_new_5_.jpg?​direct&​300 |}}
 +
 +{{ gts_new_4_.jpg?​direct&​300 |}}
 +
 +Figure 5 below shows one of the limit switch magnets, which can be moved along the rail after loosening its locking set screw with  a 0.050 Allen wrench. ​ To reduce the range of travel, move the magnets inward toward the center of the sample tray.
 +
 +[{{ gts_new_4_.png?​direct&​300 |Figure 5: Adjusting a Y-axis Limit Switch}}]
 +
 +
 +Check the operation of the limit switch by slowly moving the stage toward the end of travel. ​ When a limit is reached, the motion will be terminated and the letter “U” or “L” will appear on the LCD screen showing that the limit is in force
 +
 +
 +==== Adjusting the X Limit Switches ====
 +
 +To adjust the X Limit switches, locate the two limit switches on the X (gantry) axis.    ​
 +
 +{{ gts_new_5_.png?​direct&​300 |}} 
 +
 +Just as done with the Y axis, the X axis limit switch magnets can be moved along the rail after loosening its locking set screw with  a 0.050 Allen wrench. ​ To reduce the range of travel, move the magnets inward toward the center of the gantry bar.
 +
 +{{ gts_new_1_.png?​direct&​300 |}}
 +
 +{{ gts_new_1_.jpg?​direct&​300 |}}
 +
 +Check the operation of the limit switch by slowly moving the stage toward the end of travel. ​ When a limit is reached, the motion will be terminated and the letter “U” or “L” will appear on the LCD screen showing that the limit is in force
 +
 +===== GTS Operation ​ =====
 +
 +Refer to [[ms2000_operation|MS2000 OPERATION]] on how to setup and use the MS2000 controller with the GTS system.
 +
 + 
 +
 +===== MAINTENANCE AND SERVICE =====
 +
 +The only periodic maintenance necessary for the GTS system is occasional re-lubrication of the lead-screws,​ should they become dry enough to start squeaking. ​ The recommended lubricant is TriGEL-300S from BSA (800-882-8857). ​ Lubrication is only required when operating at the high speeds. ​ If squeaking becomes a problem, lubrication or reducing the speed are both solutions.
 +
 +The X-axis lead screw can be lubricated through the slot in the lead screw cartridge without any disassembly.
 +
 +To lubricate the Y-axis lead screw, it is necessary to remove the stage (and the optional light table, if applicable). ​ This procedure is outlined in figure 10.
 +
 +[{{ gts_1_.jpg?​direct&​300 |Figure 10:  Remove the coupling screws}}]
 +
 +
 +Remove the transport handles from the front end, and once the coupling has been de-attached,​ the entire stage can be slid off of the rails. ​ The lead-screw can then be lubricated through the slot in the cartridge.
