For safety related applications additional mechanisms (devices) are necessary to maintain safety and to avoid damage. Disregard of this advice releases the manufacturer from product liability. The meter must be operated only within values specified in the data sheet. Connection to power supply must be performed in accordance with safety instructions for electrical facilities and performed only by trained staff. Danger of Destruction! It has to be guaranteed that the excitation voltage agrees with the indicated value on the type label. Do not open the process meter.

The fast counter processes 90° phase shifted A,B signals (quadrature signals) for direction and counting information. When using ASM sensors resolutions up to 5 µm resp. 2 angular minutes are possible. The sensor excitation voltage is supplied from the meter. With four membrane keys all parameters can be programmed for the special application. An index pulse and a reference switch can be used for calibration of the measurement system. Optional comparator function with two relays and four NPN open-collector outputs are available. With the RS232 interface data can be transmitted easily to a PC, printer or PLC. Quadrature signal A Quadrature signal B Zero- or index signal Z Reference signal T (multiple function, see page 12) The reset of the display takes place for the condition ( A & B & Z ) resp. ( A & B & Z & T ) The Zero signal is a pulse signal unique within the measurement range and explicit to the phase of the quadrature signal to reset the PRODIS®INC meter. The Index signal is a multiple periodical pulse signal within the measurement range and explicit to the phase of the quadrature signal, e.g. the zero signal of an incremental encoder that appears at every single turn. The Reference signal is a pulse signal unique within the measurement range to enable the reset of the PRODIS®-INC meter, e.g. mechanical reference contact for end position recognition.

When the meter is switched on a short self test sequence will start with all LED segments on and then the version of the process meter will be displayed. After that procedure PRODIS®-INC is in the normal mode. Operation keys and display Explanation of the operation keys and display elements: LED 2 Sign LED 1 : Key to control the programming menus : Multifunction keys for parameter settings : Multifunction key to reset the display and to store the parameters in a non-volatile memory Note: + 10 means: hold key and press MAN-PD-INC-E-13 www.asm-sensor.com . ASM GmbH PRODIS®-INC Instruction Manual Explanation and operation of the functions Normal mode, displaying the position value The displayed mesurement value will be calculated as Measurement value • Multiplier Reading = Divisor + Offset value Multiplier, divisor, decimal divisor and offset are user definable parameters (for calculation examples see appendix). When the display range is exceeded, the display shows oFrAnGE. PRODIS®-INC counts every pulse edge of the quadrature signal (times 4 counting mode). Relative measurement In addition to the normal mode display PRODIS®-INC can display a second position value, a relative measurement mode with an independent zero to be set by the reset key manually. The normal mode measurement value remains in the background and will be displayed again after returning to the normal mode. With the parameter CHnul (-> CHnul=1) the display will be set to zero when relative measurement is activated. Offset function The offset function allows setting and changing of the offset value directly in the normal mode. Comparator function (for versions with comparator function only) Up to four comparator functions can defined by programming of limit value, hysteresis and operating direction. Outputs are two isolated relays with C/O contacts and four ground related NPN open-collector outputs. The operating condition of the comparators will be indicated by LED1 for relay1, NPN1, NPN3 and LED2 for relay2, NPN2, NPN4. With the parameter measurement mode (rx) the comparator function will be assigned to the normal measurement or to relative measurement. Last-value memory When the last-value memory function is activated by ISt=1 (see table page 13) the current measurement value wil be stored into memory when PRODIS®-INC is switched off. In the switched off condition, input pulses are not recognized. When the display is switched on again, the stored measurement value will be displayed.
