Figure 1.3: System Components
Measurement Objectives shown in Figure 1.3d are available in magnifications from 2.5x to 100x
and can be mounted on a turret, as shown, or in a single objective adapter.
Operator Station shown in Figure 1.3e is an typical example of the location at which the user
interacts with the system.
Power Supply in Figure 1.3f converts AC line voltage to the DC voltages required to run the
instrument. The power switch on this power supply is the main on-off switch for the instrument
electronics.
1.2 Safety Precautions
Emergency Motion Off Button (EMO)
When the ContourGT system is configured with automated stages it is equipped with an emergency
off button, located on the EMO box (see Figure 1.3c). This unit must be placed in any convenient
and readily accessible location. Pressing the Emergency Off button, or the power off button, shuts
off DC power to the system devices. However, the 24 VDC control circuit remains energized. To
re-power the system after an Emergency Shutoff, the EMO button must be released (turn counter-
clockwise), then press the green On button.
Equipment Service & Maintenance
Specific risks presented during service or maintenance of this system are described in the “ContourGT-
K Installation and Maintenance Manual”. Please refer carefully to this manual, and the lockout
tagout procedure detailed therein, before undertaking any service or maintenance task.
