CW-90/90X Checkweigher Overview The CW-90/90X is a high-speed digital weight indicator and scale base programmed to compare weight readings with predetermined tolerance limits defining an ACCEPT band. If the current weight reading is within the acceptable range, the green ACCEPT LED is illuminated. If the current weight reading is less than the acceptable range, one or more of the red UNDER segments is illuminated.
CW-90/90X Checkweigher Tare Recall When a stored tare is displayed, the gross and net annunciators are turned off and the PT annunciator is lit. To display a stored tare: 1. Press 2. Press . The tare value is displayed for 10 seconds. If there is no tare in the system, nothing will display.
6. Install coupling nuts, counter bored end first, onto threaded stem of rubber feet. 7. Install feet onto bottom side of the column. 8. Turn the CW-90/90X upright and replace the platter on the platform. 9. Attach indicator to the column with the two knobs and nylon washers provided. Position nylon washers between indicator enclosure and column mounting holes.
Leveling Set the CW-90/90X in an area that is level and free of vibrations and air currents. Adjust the four corner feet on the base and refer to the bubble level on the inside frame. The base should not rock and the feet should have solid contact with the surface.
CW-90/90X Checkweigher 2.6.2 Serial Communications Port 1 supports full duplex RS-232 communications only; Port 2 provides either active 20 mA output or duplex RS-232 transmission. 1. Wire serial communications cables to J2, which is Port 1 (5-wire RS-232 port) and J3, which is Port 2 (RS-232 and 20 mA).

CW-90/90X Checkweigher The Under value you are entering is a negative value. However, it will appear to be a lower number than the Over Note value on the display because the negative symbol is not displayed. An example of Over/Under negative checkweighing values as they appear on the display would be Over: 3 (actually recorded as -3) and Under: 1 (actually recorded -1).
Serial Commands The CW-90/90X can be controlled by a PC or remote keyboard connected to an indicator serial port. Control is provided by a set of serial commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions.
6.1.3 Clear and Reset Commands RESETCONFIGURATION can be used to clear and reset the CW-90/90X: Reset System ( ) – resets the indicator without resetting the configuration. RESETCONFIGURATION – restores all configuration parameters to the default values (menu mode only). It can also be initiated by navigating to the DEFALT parameter in the VERS menu and selecting YES.

CW-90/90X Checkweigher Print Formatting The CW-90/90X provides seven print formats, GFMT, NFMT, ACC.FMT, STRM.FM, BUS.FMT, HDRFMT1 and HDRFMT2. These determine the format of the printed output when the PRINT key is pressed or when a KPRINT EDP command is received. The GFMT and NFMT will print to all ports assigned as DEMAND in the TRIGGE parameter, based on whether a tare is in the indicator.
7.2.1 Using the EDP Port With a personal computer, terminal, or remote keyboard attached to the CW-90/90X EDP port, you can use the EDP command set to customize the print format strings. To view the current setting of a format string, type the name of the string (GFMT or NFMT) and press Enter. For example, to check the current configuration of the GFMT format, type GFMT and press Enter.
WiPort™ wireless networking device (PN 108671) can be installed inside the ® CW-90/90X Checkweigher. This option is used to communicate with a serial port on the host indicator. The Windows -based configuration software, DeviceInstaller™ (available on the CD that comes with the kit) can be used for installation and setup after the option card is connected to your wireless network.
