PRODIS
®
-INC
Instruction Manual
The process meter PRODIS
®
-INC is designed for use with incremental
position sensors to display angles and displacements. 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 RS-
232 interface data can be transmitted easily to a PC, printer or PLC.
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 measure-
ment 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.
Description
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 )
