Connection to a
distributed system
with or without event
sequence reporting

When connecting a SACO 64D4 to another
SACO 64D4 or to the control data communica-
tor SACO 148D4, they can share the group alarm
relays, the interlocking lines, the self-supervision
relay and the audible alarm relay.

The units are interconnected by means of a flat
cable and the connectors marked X16 on the
mother PC-board of both units. The cables are
brought in under the rear plate of the units
through the cutout along the lower edge of the
panel. When several units are to be connected
to the SACO 148D4, the flat cables are to be
chained together. The following cables are avail-
able for the purpose:

Cable type SWIR 24

Intermediate cable for two racks

Cable type SWIR 25

Intermediate cable for three racks

Cable type SWIR 26

Intermediate cable for four racks

Cable type SWIR 27

Intermediate cable for five racks

Cable type SWIR 28

Intermediate cable for six racks

An already mounted system can be extended by
using a flat cable extension module type SWCM
8A1. The extension module is attached to the
last rack and the extension is made with a suit-
able cable. The mounting instructions are
packed together with the extension module.

The group alarm reflash functions can be con-
nected in parallel by fitting a flat cable to the
terminals X21, X22, X23 and X24 of SACO
64D4. The cable is then extended to another
SACO 64D4 or 148D4 to its X21…X24 ter-
minals.. From a system united in this way 16
group alarm output contacts are obtained. The
type designation of the cable is SWIR 23.

When the group alarms of several SACO 64D4
systems are to be parallelled, the output con-
tacts are recommended to be parallelled.

In the last rack of the system the terminating
resistors R1 and R2 of the SPAbus must be con-
nected but from the other racks they ought to
be removed. The resistors which are located on
the mother PC-board are connected or discon-
necting by means of a jumper on contact X46.
R1 is connected by short-circuiting the poles
1-2 and R2 is connected by short-circuiting the
poles 4-5.

Connection to a
distributed system

The components in the SPACOM system are
linked together, optically, over the SPA-bus.

The higher level system can obtain data for for
event sequence reporting purposes. Remote set-
tings can also be performed trough the serial
communication interface.

For connecting the SACO 64D4 units to the
fibre optical loop, bus connection modules are
used. SACO 64D4 can be connected both to
SPA-bus and LON-bus systems.
