Af Interface O4Le; Telephony; Teleoperation - ABB ETL600 Instruction Manual

ABB Switzerland Ltd
***) Also available without LSA Plus Quick Connect (Krone) with lengths of 3,
10 or 20 m to be used for terminating on main distribution frame.
LSA Quick Plus quick connect is manufactured by KRONE. With this
system the connections to the AF interfaces can be made quickly
without soldering. A push-on tool (referred to as a KRONE tool), which
is supplied as an accessory, permits insulation displacement,
connection and cutting of the wire at the same time. For best results, a
solid wire of 0.5 mm diameter with a PVC insulation of 0.2 mm
thickness should be used.

AF Interface O4LE

The AF universal interface module O4LE has following main functions:
•

telephony

•

teleoperation

•
external teleprotection equipment
The external connections are divided on two Krone connection strips:
Telephony and Teleoperation.
6.6.3.1.1. Telephony
The first connection strip is for telephony connections as shown in Fig.
6-13.
The interface programmed for 2 wire subscriber, for point-to-point
operation or remote end subscriber or PAX side subscriber should be
connected to terminals 10a /10b.
The interface programmed for 2 Wire/4 Wire, E&M operation. 2 wire
speech should be connected to terminals 8a / 8b.
4 wire speech Tx should be connected to terminals 1a / 1b.
4 wire speech Rx should be connected to terminals 2a / 2b.
M wire (terminal 4a) is activated by positive potential provided on
terminal 4b. I.e. PAX should provide a potential free contact.
E signal should be connected between terminals 3a / 3b.
Transit connection / compander control (terminal 5a) is activated by
positive potential provided on terminal 4b. I.e. PAX should provide a
potential free contact.
PAX blocking in case of bad SNR can be done by the change over
relay contacts provided. (6a, 6b and 7a)
The interface programmed for 4 Wire, E&M operation.
4 Wire speech Tx should be connected to terminals 1a / 1b.
4 Wire speech Rx should be connected to terminals 2a / 2b.
M wire (terminal 4a) is activated by positive potential provided on
terminal 4b. I.e. PAX should provide a potential free contact.
PAX blocking in case of bad SNR can be done by the change over
relay contacts provided. (6a, 6b and 7a)
6.6.3.1.2. Teleoperation
The second connection strip is for teleoperation / external
teleprotection connections as shown in Fig. 6-13.
