Damages that arise from non-observance of the guidelines in the user guide shall be devoid of any liability. – – – – – The device may only be used in the manner described in this user guide. No technical modifications may be made to the device. The device may not be used if the environmental conditions (temperature, humidity etc.) are not within the limits indicated in the specification.
Intended use 2 Intended use The ITP11 is a universally applicable, digital display unit. It is designed to be connected to any transmitter with a 4-20 mA output. The device requires no auxiliary power and is supplied directly from the measured current. The field of application of the device includes the control and monitoring of industrial processes. The display can be used in automated systems as a primary or secondary display.
Specifications 3 Specifications ITP11 can be ordered in different versions. They differ in the display color. Ordering key: ITP11-X - - Display color red G - Display color green Table 1 Supply current Input signal Inputs Measuring range Normal operation Voltage drop, max.
Functional description 4 Functional description A 4-digit, 7-segment LED display with 14 mm character height is located on the front of the device for displaying the measured values, error messages, functions and values during programming. The programming buttons are positioned on the cylindrical surface of the device. The button is used to set the programming mode and to apply the changes. The parameters can be se- lected and changed using buttons rameter changing in three steps. and .
Installation and operation 5 5.1 Installation and operation Installation The device is designed for switch panel mounting in a borehole of Ø22.5 mm (see Appendix A for dimensional drawings). Carefully position the supplied gasket on the display rear surface. Insert the cylindrical part of the device into the borehole and tighten the nut from the rear side of the switch panel. Connect the device to the signal cable in accordance with Appendix B.
