3. BASIC REQUIREMENTS, OPERATIONAL
SAFETY
The controller conforms to a safety standard EN 61010-1.
Additional comments concerning safety:
• Assembly and installation of the electrical connections
should conducted only by people authorized to perform
assembly of electric devices.
• Always check the state of connections before turning
the controller on.
• Prior to taking the controller housing off, always turn
the supply off and disconnect measuring circuits.
• Removal of the controller housing during the warranty
period voids the warranty.
• The device is designed to installation and usage in the indu-
strial electromagnetic environment.
• A switch or a circuit-breaker should be installed in the buil-
ding or facility. This switch should be located near the device,
easily accessible by the operator, and suitably marked.
4. INSTALLATION
4.1. Controller installation
Fix the controller to the board with three screw
brackets as shown in the fig. 1A slot in the panel must have
the following dimensions: 92.5+0.6 x 92.5+0.6 mm. The thickness
of the panel material cannot exceed 6 mm.

4.2. Electrical connections
The controller has three separate strips with screw
terminals. Two strips with 16 terminals each allow to connect
all signal sources by a wire with a 2.5 mm2cross-section,
and two strips with 10 terminals each allow for connecting by
a wire with 1.5 mm2cross-section.

ETHERNET CONNECTION
For Ethernet connection use the category 5 shielded
twisted-pair wire with RJ-45 connector, compliant to
the following standards:
• EIA/TIA 568A for both connectors in strike-
-through connection (i.e. between RE92
and hub or switch),
• EIA/TIA 568A for the first connector and EIA/
TIA 568B for the second one in the cross-over
connection (i.e. when connecting RE92
to the computer).

4.3. Recommendations for installation
To achieve full electromagnetic resistance of the con-
troller, it is necessary to follow the rules described below:
–do not supply the controller from the network in the proximi-
ty of devices generating high pulse noises and do not apply
common earthing circuits,
–apply network filters,
–wires leading measuring signal should be twisted in pairs
and for the resistance sensors in the three-wire connection
they should use twisted wires of exactly the same length,
cross-section and resistivity protected by shielding,
–all shields should be one-side earthed or connected
to the protection wire, the nearest possible to the controller,
–as a rule of thumb, wires transmitting different signals sho-
uld be spaced as far as it is possible (at least 30 cm) and
should be crossed only at the right angle (90 degrees).
–to connect RE92 controller to the Ethernet it is recommen-
ded to use:
• U/FTP – twisted pair cable with separate foil shielding
for every pair,
• F/FTP – twisted pair cable with separate foil shielding
for every pair and additional foil shielding for the cable,
• S/FTP (former SFTP) – twisted pair cable with sepa-
rate foil shielding for every pair and additional mesh
cable shielding,
• SF/FTP (former S-STP) – twisted pair cable
with separate foil shielding for every pair and additional
mesh and foil cable shielding.

6.1. Information bar
Information bar displays the state of outputs, binary
inputs and real-time clock. When active binary outputs
and inputs are displayed in black, inactive ones are displayed
in light grey color. State of the outputs, binary inputs and real-
time clock can be hidden.
5. STARTING WORK
After turning a supply on, the controller displays logo and then
moves to the normal operational mode.

6.2. Button markings
Depending on the service location, controller buttons
can perform different functions. Functions are described
in the bar on the bottom of the screen. If the button lacks
description, it is inactive at the moment. Fig. 5 shows an example
of the button marking.
