Control Panel ETV 1991
The control panel is an intelligent terminal for programming and visualization of automated
processes. Process diagnosis as well as operating and monitoring automated procedures
is simplified using this terminal.
A touch screen serves as the input medium for process data and parameters. The output
is shown on a 19" SXGA TFT color display.
With the LSE mask editor, graphics can be created on the PC, then stored and displayed
on the terminal.
The available interface connections can be used to exchange process data or configure
the terminal. An internal Compact Flash serves as the storage medium for the operating
system, application and application data.
The integrated, high-performance VARAN bus enables the direct control of I/O modules.

Problems can arise if a control is connected to an IP network, which contains mod-
ules that are not running with a SIGMATEK operating system. With such devices,
Ethernet packets could be sent to the control with such a high frequency (i.e. broad-
casts), that the high interrupt load could cause a real-time runtime error or runtime
error. By configuring the packet filter (Firewall or Router) accordingly however, it is
possible to connect a network with SIGMATEK hardware to a third party network
without triggering the error mentioned above.

Storage Media
It is recommended that only storage media provided by SIGMATEK
(CompactFlash cards, microSD cards etc.) be used.
The number of read and write actions have a significant influence on the
lifespan of the storage media.
Il est recommandé d’utiliser uniquement les supports de stockage fournis par
SIGMATEK (Cartes CompactFlash, cartes microSD, etc).
Le nombre de lectures et d'écritures ont un effet significatif sur la durée de vie du
support de stockage.
Buffer Battery
The exchangeable buffer battery ensures that programs and data in the expanded
memory (SRAM) as well the clock time (RTC) are preserved in the absence of a supply
voltage. A lithium battery is installed at the manufacturer.
The battery has enough capacity to preserve data in the absence of a supply voltage for
up to 2 years.
We recommend however, that the battery be replaced annually to ensure optimal perfor-
mance.

Battery Exchange
Switch off the terminal.
Loosen the marked screws and open the
housing.
The corresponding screws are:
2 pieces
Combination pan-head screw M3x6
10 pieces
PT screws countersunk head KA40x10
Remove the battery and replace it with the
new battery.
The negative pole of the battery must be on
the board side.
The exchange must take place within 5
minutes with the terminal switched off,
otherwise zero voltage safe data (SRAM,
date and time) will be lost.
Close the housing and switch on the termi-
nal.

Wiring Guidelines
Earth Connection
The terminal must be connected to earth through the mounting on control cabinet or over
the terminal provided. It is important to create a low-ohm earth connection, only then can
error-free operation be guaranteed. The earth connection should have the maximum cross
section and the largest electrical surface possible.
Any noise signals that reach the terminal over external cables must be filtered over the
earth connection. With a large electrical surface, high frequency noise can also be dissi-
pated (skin effect).
CMB

ETV 1991 CONTROL PANEL
Page 16 21.06.2018
Shielding
For the CAN and DIAS bus wiring, twisted pair shielded wires should be used. The cable
shielding must be connected to earth either directly before the terminal over a large sur-
face and with low Ohms using grounding clamps or with a blade terminal. With Ethernet
and the VARAN bus, CAT5 cables with shielded RJ45 connectors are required. The
shielding in the CAT5 cable is connected to earth through the RJ45 connector.
Noise therefore cannot reach the electronics and affect the function.
ESD Protection
Typically, USB devices (keyboard, mouse) are not equipped with shielded cables. These
devices are disrupted by ESD and in some instances, no longer function.
Before any device is connected to or disconnected from the terminal, the potential should
be equalized (by touching control cabinet or earth terminal). Electrostatic loads (through
clothing and shoes) can thereby be dissipated.
DIAS Bus Termination
In a DIAS bus system, both end modules must be terminated. This is necessary to avoid
transmission errors caused by reflections in the line.
The DIAS bus termination is integrated in the terminal and must no longer be built into the
DIAS bus connector.

CONTROL PANEL ETV 1991
21.06.2018 Page 17
DIAS bus with C-DIAS modules
To ensure a good bus connection, several wiring guidelines must be followed:
•The cable used must be designed for the data transfer speed:
Data cable (10 MBit, 2 x 2 wire TWISTED PAIR, shielded)
E.g.: LAPPKABEL / UNITRONIC-BUSLEITUNG FD P LD
•Because of the internal resistance of the module, the cable impedance should be
100 Ohms.
•With twisted-pair cables, ensure that the correct pairs are connected to one another:
2x2 pair cables: Pair 1 MBUS+, MBUS-
Pair 2 SBUS+, SBUS-
•The shielding must be connected over a large area and the shortest possible route.
•To connect the individual wires to the connector, the insulation must be removed and
the exposed shielding shifted to the side. Only remove as much of the insulation and
shielding as needed.
•The send and receive modules must have the same GND potential.
The maximum length allowed for twisted-pair cables 20 m (when using the UNITRONIC
bus cable FD P LD / Fa.LAPPKABEL)
DIAS bus with DIAS modules
It is also possible to connect the terminal to a DIAS module. However, the DIAS modules
require a power supply (a DPS 001, for example) as well as an adapter module for con-
nect the twisted-pair cable to the ribbon cable connector (i.e.: DKO 012 /013).

If the terminal is an end module, it can be terminated by placing a 150-Ohm resistor be-
tween CAN-A (Low) and CAN-B (High).
USB Interface Connections
The terminal has two USB interface connections that can used to connect various USB
devices (keyboard, mouse, storage media, hubs, etc.) in LASAL. Several USB devices,
which are fully functional in LASAL, can be connected using a hub.
The following restriction applies to the BIOS setup:
The BIOS setup can only be operated when the USB keyboard is connected directly to the
USB socket. Using a USB hub can cause errors in the BIOS setup!
It should be noted that many of the USB devices on the market do not comply with USB
specifications; this can lead to device malfunctions. It is also possible that these devices
will not be detected at the USB port or function correctly. Therefore, it is recommended that
every USB stick be tested before actual use.
