1.2 Description
Mounting the target display is by using the attached mounting plate that is fixed at the machine by using two
screws. The target display can be hooked onto the brackets provided at the mounting plate.
The position data will not get lost even in case of power failure (min. 10 years).
The current position value is indicated as running value in the two-line LCD display with backlight (2 x 5 digits,
numeric). Optionally the target received by the control unit (master) can be indicated simultaneously in the same
display. Two arrows show the editing engineer the turning direction in order to align current value with target. As
soon as the current value is in coincidence with the target and within the tolerance window, the target will disap-
pear. Programming the relevant parameters at the master enables the display to be turned by 180° to allow ver-
tical installation of the target display. Connecting the target display is by the help of an M8 connector. Power
supply of all target displays connected is by the same cable directly by master. Programming of target display by
master only.
