Table 2: Indication of diagnostic status
Set plug monitoring as part of Ready message
From version 2.2 the motor plug monitoring message can also be
assigned to Ready message DI0 (
a section “I/O assignment” on
page 48).
This is recommended if
• the motor plug is used as isolating switch in combination with
lock shackle SET-M-LOCK (
a
page 152).
• motors without temperature sensor winding are used and T1/T2
in the motor’s terminal board are bridged (
a
figure 55 on
page 53).
If maintenance work is performed under these conditions with
disconnected and locked motor plug, a Not Ready signal makes
more sense than a fault message.
To activate this operating mode, close the left hook jumper
(
a
table 3 on page 61).
In this operating mode, a high-resistance connection between pins
5 and 8 of the motor plug (thermistor tripping or no motor plug)
the following effects:
• The motor switches off (as in the normal operating mode).
• No group fault message is applied to DI1.
• LED Motor does not indicate a group fault message.
• No Ready signal is applied to DI0, even if the key-switch is set
to AUTO.
Setting the functions with DIP switches/jumpers
When the locking screw in the cover is undone, the electronics can
be configured through jumpers and DIP switches.

settings, make sure the key-switch is in its OFF position.

RA-MO version 1.x registers changes in the DIP switch
settings only when power supply is interrupted and
reconnected or the 24 V are applied again. From version
2.x changed DIP switch settings take effect immediately.
