Note
Open input
An open input is interpreted as "low".
To enable the digital inputs to function, connect terminals MEXT1 and MEXT2. This is done
in one of the following ways:
● The incorporated ground reference of the digital inputs
● A jumper to terminal M
In this case, the isolation for these digital inputs is removed.
Note
Diagnosis when the 24 VDC auxiliary voltage fuse ruptures
The 24 VDC auxiliary voltage is protected internally by a 4 A fuse. A ruptured fuse is indicated
by loss of the auxiliary power and/or by a diagnostic message. All digital outputs are also
affected by a ruptured fuse. You will not be able to replace this fuse. Replace the component
and send it for repair.
