Installation
Before installing the instrument, heed the following warnings:
a)
Connect the instrument strictly following the instructions of the manual.
b)
It is the responsibility of the user to check, before using, the correct setting of all parameters of the
instrument to avoid damage to persons or things.
c)
The instrument CANNOT function in a hazardous environment (inflammable or explosive).
d)
The unit contains parts sensitive to electrostatic charge, therefore handling of the internal electronic
cards has to be carried out with appropriate care to avoid permanent damage.
Description
The electronic position indicator EP43RS / EPRS, which includes within the same case a position transducer
and a display unit, is a device for measuring linear or angular movement which is compact, easy to install,
and applicable in several types of industry (packaging, woodworking, aluminum, sheet metal, etc.)
This device simplifies and quickens format changeover on machines with manual axis adjustment (for ex.
with hand-wheels).
The backlit LCD display has two lines: the first shows the current value and the second shows the value to be
reached in the new machine configuration.
The target value is communicated to the EP43RS / EPRS via a serial interface with the PLC to allow a
manual changeover by handwheel. The two LEDs indicate if the target value has been reached or not.
With the 3 frontal keys it is possible to program the value on the display for every rotation of the hollow shaft
and activate the following functions: reset/preset of the value, absolute/relative measurement, mm/inches
conversion, and reading range in degrees.
The instrument must be powered externally with a 10-30VDC power supply and is equipped with an internal
backup battery which assures that the value is updated and saved, even in the absence of external power, for
a period of 6-8 years. When external power is not present, the display is off and the serial port is inactive.
The robust case of the EP43RS / EPRS is made of aluminum alloy which is billet machined and anodized
while the hollow shaft is made of stainless steel and is supported by ball bearings.
Programming
To access programming of the parameters, keep pressed until
appears on the display. Then press
O
2 times and 3 zeroes will appear. The first digit on the right will blink: using (digit increase) and.
(digit
selection) insert the pass code which is 273 and confirm with
O
. In case of incorrect insertion of the
password, the unit exits the programming mode.
The various parameters can be scrolled with and appear in the following order:

To set a negative number, press until the last digit on the left blinks then press once again and after press so
that the minus sign will appear.
To exit programming press
