Connecting An Alarm With Dry Contact; Connecting The Remote Reset; Relays Connection; Ethernet Connection - Stahl EC-94 Série Manuel D'instructions

7.5.2 Connecting an alarm with dry
contact
Connect terminals AL1 and COM to connector J6 as
shown in the image (Fig. 15, page 101).
Maximum length of the alarm cables: 200m (656ft).
Use a shielded cable to carry out the connection.

7.5.3 Connecting the remote reset

Connect the two RST terminals on connector J6 as
illustrated in the figure (Fig. 15, page 101).
Maximum cable length: 200m (656ft).
Read the Factory Default chapter to find out how to
use the remote reset (11.2.3 Factory Default, page
107).

7.5.4 Relays connection

Maximum relay voltage and current: read
the technical data in the relevant chapter (
15 Technical data, page 110).
Connect terminals RL1A, RL1B, RL2A, RL2B to
connector J8 as shown in the image (Fig. 15, page
101).
The device can be equipped with a washing system.
Use the terminals RL2A and RL2B to control the wash
system.

7.6 Ethernet connection

The product is equipped with an integrated Ethernet
switch that manages a RJ45 port and a slot for SFP
modules.

7.6.1 Connection via RJ45

Make connections in accordance with the
TIA/EIA-568-B standard.
Connect the Ethernet cable to port RJ45 (7.3
Connector board description, page 100).
Use of Ethernet cables with the following
characteristics is highly recommended:
• STP (isolated)
• Category 5E or category 6
Use a shielded RJ45 connector on both ends of the
cable. The Ethernet cable shield (user side) must
always be earthed via the connector.

7.6.2 Connection via SFP

The optical modules compliant with the SFP
(Small Form Factor Pluggable) standard
are conversion devices of the electrical to
optical signal and the optical to electrical
signal.
The SFP module is used for the optical fiber
connection. The SFP module should be suitable for
the installation system.
Consult the SFP module manual for the relevant
specifications.
The SFP module (not supplied by STAHL)
must meet the following requirements:
• Laser: Class 1, complies with EN60825-1
• UL/IEC 60950-1 or UL/IEC 62368-1 Certi-
fication
The user switch, connected via the SFP
module, must work at a speed of 100Mbps.
Check the settings of the switch to which
the product is connected.
STAHL has tested various types of SFP
modules. For further information please
contact the STAHL service center.
Insert the SFP module (not supplied) in the SFP slot (
7.3 Connector board description, page 100).
