Your unit is rated for NEMA 4 (water-tight) and NEMA 12 (dust-tight) environment, provided you install it with its gasket intact in a similarlyrated enclosure. D.3 Dimensions of PWS30xx This section illustrates the dimensions of the Workstations themselves as well as the cutout dimensions. The unit of dimensions is millimeter. You should allow 10 cm (4") of clearance behind the workstation for cable connectors and 5 cm (2") above and below for airflow. Method of installation: Mount the PWS to the preserved hole from the front side. Attach the mounting brackets from behind, and fasten the screw of the brackets with a screwdriver. Don't tighten the screws with too much force or it may cause a damage of the panel. D-3 PLC Workstation Supplement D D.3.1 Dimensions of PWS31xx D.3.2 Torque Specifications After placing the Workstation in the cutout, you should tighten each nut to 0.07 newton-meters (10 inch/pounds) of torque. If you don't have a torque wrench, then try to tighten the nuts to compress the gasket to about 50% of its D-4 About PWS3000/3100 original thickness. D.4 Power Connections You must ground your Workstation at all times. You should also ensure that the Workstation is on the same ground as any other equipment connected to its communications ports. D.4.1 Power Connector The three-position power connector accepts 24VDC only. The unit's power consumption is shown in the following: Item / Model Power Consumption Fuse Rating 30xx-STN 31xx-STN 24VDC10% 15W 1A 30xx-FSTN 31xx-FSTN 24VDC10% 15W 1A 30xx-TFT 31xx-TFT 24VDC10% 20W 1A Be sure to use all three terminals when connecting power. To make a connection, strip about 0.64 cm (1/4") of insulation, turn the screw counter-clockwise until the gap is wide open, insert the wire all the way in, and turn the screw clockwise until it's tight. D.4.2 Electrical Grounding You must make sure that your Workstation is properly connected to earth ground, to prevent it from radiating radio frequency noise. If you connect a communications cable to your unit after static electricity has built up or when the Workstation and the other device are on different grounds, the resulting discharge could damage the electronics in either device. D.5 Touch Panel The PWS30xx/PWS31xx is equipped with a 9.4" VGA sized (640Hx480V) flat panel display and analog resistive touch screen. You can design touch keys for each of your screens. You can configure a touch key to display another screen or control an on/off location within your PLC. The shape of the touch key must be rectangular, but the size of a touch key is configurable and can be as small as a single touch switch or as large as the entire screen. One screen can have up to 80x60 touch keys for PWS3100. For each changeable Object of a screen, the Compile function of ADP3 automatically groups D-5 PLC Workstation Supplement D those touch switches that the display area of the Object covers to form a touch key for the selection purpose. When you press a touch key, the Workstation responds by sounding the buzzer for 200 milli-seconds (default) and reversing the color of that touch key for 200 milli-seconds. With the feedback, you know the Workstation accepts your key-press. You can use Miscellaneous Settings dialog box of ADP3 to set the parameter of touch screen for your Workstation. Figure D-1 Figure D-2 D-6 Figure D-3 About PWS3000/3100 D.5.1 Built-in Touch Keypads The built-in touch keys are touch keys that the ADP3 automatically configure for your application so that you don't have to spend any time to program them. The built-in touch keys allow the operator to select and change a PLC location very easily. There are two groups of built-in touch keys called Numeric Touch Keypad and Password Reentering Keypad that the Workstation displays for you to change data.

If DIP switch No.6 is off, the Workstation doesn't ask you to enter a password and the default user level is 1 after the power-on self-test if the DIP switch SW8 is set to on; the default user level is 3 if the SW8 is set to off. If a password is required, the Workstation doesn't continue its operation until a legal password is entered. D.12.1 Password and User Level The Workstation saves passwords in the Real Time Clock chip. A password must have eight numeric characters. When you create a password, you must specify the user level associative with that password. The user level of a password determines the privilege of the user who enters that password to start the operation of the Workstation. When a user wants to use the function of the System Menu, change to another screen, or make change to a PLC location, the Workstation checks the user's user level. There are three user levels: level 1, level 2, and level 3. Level 1 users have the highest privilege and Level 3 users have the lowest privilege. The passwords and their user levels of your application are unpredictable until you define them. D.12.2 Registering Passwords To register new passwords or modify existing passwords for your application, you have to create an Action button on a screen and assign the function "Display Password Table" to that button. When the Workstation is running the application, a level 1 user can get the password table as the example shown below when he presses and releases an Action button that displays the Password Table. You can register up to eight passwords for your application. To change a password or the user level of a password, (1 ) Select the password or the user level by touching it. D-22 About PWS3000/3100 (2 ) If you select a user level, enter a number between 1 and 3 to change the user level. If you select a password, enter eight numeric characters to change the password. When you press [ENTER], the Workstation accepts the change. (3 ) To abandon the current change, select another field to exit the current selection. (4 ) To save all changes that you made to the password table, press [Save & Quit]. To abandon all changes, press [Quit].
