Commissioning and operation
It is not possible to teach the same actuator on
the same evaluation unit more than once.
The number of valid Teach-in operations on one
evaluation unit is limited to a maximum of 8.
The evaluation unit can be operated only with the
last actuator taught.
A Teach-in operation is invalid if:
–the Teach-in operation is aborted before the
green LED goes out,
–The supply voltage has been disconnected
during the Teach-in operation.
The system automatically reverts to Teach-in
mode even after the 8th Teach-in operation or if
an "old" actuator is moved against the read head.
In both cases, a Teach-in operation lasting 60 sec-
onds is initiated, but the last actuator code
remains active in memory (see chapter 6.2
"System status table"); no new code is taught.
