FSM21 Front Switch Module
For connection to the FBM38 fieldbus module.

M
acro Function
The functions of the two 2 or 1-stage device controls are made by assigning macro 21 on the FBM38 fieldbus
odule.
m
Using the macro function, relay outputs K1/K2 and K3/K4 are each controlled on the FBM38 with 2-stage control.
Depending on the switch setting, the relays lock against each other or switch together. A mechanical limitation of the
switch positions can be made by attaching switch stop rings (see the “Switch stop” section).
A
load/rolling switch with different switching delays can be set in macro 21.
Binary inputs 55/IN–58/IN on the FBM38 are defined as malfunction messages by the macro function, and are
hown on the signal LEDs (1.3/1.4, 2.3/2.4) on the FSM21.
s
Depending on the operating mode set on the FBM38 ( / ), the following is signaled by the signal LEDs (1.1/1.2,
.1/2.2):
2
Binary inputs 51/IN–54/IN as operating messages (“Remote” operating mode )
The status of relay outputs K1–K4 on the FBM38 (“Local” operating mode )
A
ll macro settings are made on the FBM38 fieldbus module.
The FBM settings and a detailed macro description are found in technical data sheets 2.50-30.038-01-en and
2.50-30.038-02-en. Both of these are included with the FBM38
fieldbus module.
