Changing The Mode Of Operation For Relays On Swom 16A1 - ABB SACO 16D3 User Manual And Technical Description

Changing the
mode of operation
for relays on
SWOM 16A1
The output relays on the relay module SWOM
16A1 can be used in two ways. The output relays
can be used either as field contact signal follower
or group alarm output relays.
In order to switch over from one function to the
other the front plate is first to be removed by
unwinding the four finger screws. Thereafter
the alarm module SWPM 3A1 is withdrawn
from the case by grasping the knob marked
"PULL". Now two flat cables become visible,
one with a connector marked "SIGNAL FOL-
LOWER" and the other with a connector marked
Fig. 24. Changing function of the output relays on the SWOM 16A1 module
"GROUP ALARM". The one needed is snapped
to the counter connector on the output relay
module SWOM 16A1, see the figure below.
Now the alarm module can be reinserted and the
front plate can be refitted.
The output contact of the relay module SWOM
16A1 are normally open (NO) contacts. If the
"GROUP ALARM" function has been selected,
the first two output relays of the relay module
operate in parallel with the two fixed group
alarm outputs 1 and 2, see figure 10 on page 12.
