Describtion of the device and it´s interfaces
4.1 General
description
The Active Mini-Starcoupler in the plasic housing is a hard-wired and
tested functional unit, which can only be extended by it´s external
interfaces. They are provided with a clip-on mounting for DIN EN 50022
top-hat rail 35 mm. With screw type terminals the auxiliary power supply
can be safely connected and an alarm contact also. The fibre optic
cables are connected via the FSMA screw-type terminals or the ST
bayonet catch terminals. The RS232 interface is connected via a 9 pole
sub-D socket and the RS485 interface comes out via a 2 pole
COMBICON plug connector. The device is free of silicone and halogen
as well as flame-retardant.
4.2
Position and assignment of the terminals
4.2.1
Auxilliary voltage X2
The auxilliary DC voltage (at L- and L+) or AC voltage (at N and L1) is
connected to the terminals X2 (see figure 1). Because the device has no
ON/OFF switch this switch must be installed external if it´s necessary.
4.2.2
Alarm contact X7
The link to the alarm contact takes place at the clamps X7 1/2. The
potential free normally-closed contact opens, if the device is in
operation, and closes if supply voltage is missing or an internal error
occurs.
4.2.3
Optical interfaces Tx/Rx
The 5 optical interfaces are marked with Tx (Transmit) and Rx (Receive)
and numbered from 1 to 5 (see fig. 1). The optical connections are
equipped according to the order code with FSMA or ST plugs. The fibre
connections to other devices must to be crossed, that means the
transmitting output Tx is connected with the Rx input and vise versa.
