Signal conversion / amplification The 2261 converts bipolar mV signals from transducers supplied directly by the module to standard current / voltage signals. The 2261 is suitable for load cell applications. By way of the relative calibration function the scale can be tared, i.e.
Technical characteristics In general: The 2261 is microprocessor-controlled and basic-calibrated meaning that input and output can be programmed acc. to the requested signal range without any readjust ment. This guarantees high accuracy and flexibility. The user interface consists of a 3-digit display and 3 front function keys which are used for taring or change of input / output signal range.
Front error LED At an incorrect output, the red LED will flash, e.g. at overrange saturation. Transducer supply Front-programmable to 5...13 VDC. It is up to the customer to ensure a max. load of 230 mA (e.g. 6 parallel 350 Ω load cells). Sense When the transducer supply is applied, the sense input can be used for compensa- tion for cable resistance to the transducer.

PROGRAMMING / OPERATING THE FUNCTION KEYS DOCUMENTATION FOR ROUTING DIAGRAM General The programming is menu-controlled. The main menus are numbered in level 0 (X.0), and the submenus are numbered in level 1 (X.1 - X.5). Each submenu has an accompa nying entry menu. The menus are structured in such a way that the menus most frequently used are closer to the default menu 0.0.

tAR - Taring When submenu 5.1 has been selected for {tLO or tHI}, activating the key for more than 2 s will tare the input value to the value it had when activated. The input span is not affected but is kept relative to the new offset value.

Example: A signal of 5...15 mV corresponds to a weight of 0...1000 kilo. It must be possible to detect a 50% overrange of the scale on the analogue output of the mV transmitter at the same time as the display shows 150%.
4.3 UI - Selection of current or voltage output See the hardware programming for correct jumper setting. Possible selections are: 001 = Current output in the range 0...10 mA 002 = Current output in the range 0...20 mA 003 = Voltage output in the range 0...500 mV 004 = Voltage output in the range 0...1000 mV 005 = Voltage output in the range 0...5 V 006 = Voltage output in the range 0...10 V...
