When using a colored line sensor, use "F 1" to switch between light line, dark line and color contrast. On the operating panel for the support beam it is possible to switch between left drive, right drive and both drives. F 2 Switch between operating panels The "F 2" key can be used to switch between the existing operating panels. F 3 Oscillation The oscillation stroke (amplitude) and time are set here. F 4 Multi-operation Using the multi-operation function, key "F 4", up to 8 control loops may be operated by just one command station DO 200. . The groups that are to be operated simultaneously are selected in menu "F 4". Values (web offset, web width etc.) may be displayed by one of these selected groups.
"Increase value" / "Decrease value “key A web offset may be set via these keys in automatic mode. In manual mode, the actuating element or positioning carriage may be shifted to the left/right. Variable numbers, e.g. parameters, parameter values etc. may be changed. Shortly before reaching the end position, the display in the appropriate key ?ashes, once the actuating element reaches its end position, the display lights up. Simultaneous pressing effects a reset of the web offset to "0" in automatic mode, a jump back to the start of the parameter list or in the parameter itself, the parameter value will be set to 0.

Command station DO 2000 / DO 2001 "Automatic" key If the "Automatic" key is pressed, the green display will light up on the key. If the display ?ashes, the guider block signal is supplied and automatic mode inhibited. The function of the "Automatic" key depends on the setup settings in parameters ".9.9. >operatorkey con?g" and ".1.1. >osc. trigger mode" of device X.5 (master device). Amongst others, automatic mode may mean: a. Guiding by the web center, an edge, line or colour contrast If the automatic key is pressed, the web guider controls according to the signals of the selected sensors. Both sensors must be selected for guiding by the web center. b. Hybrid (machine center) If the automatic key is pressed, all support beams and sensors are selected, the web guider controls according to the machine center (automatic hybrid mode). c. Oscillation The "Oscillation" function must be set in parameter ".1.1. >osc. trigger mode" in the master device address X.5 and may be selected in addition to operating modes a. and b.. In oscillation mode, the web is moved in parallel to the left and right. "Center mode" key If the "center mode" key is pressed, the actuating element moves itself to the stored center position. While advancing to the center position, the display ?ashes. Once the center position is reached, the display on the push button lights up. "Manual mode" key If the "manual mode" key is pressed, the display on the push button lights up, the actuating element may be moved to the left or right via the "Increase/Decrease value" keys. In "Support beam" mode the positioning carriage may be moved to the left/right via the "Increase/Decrease value" keys.
