Installation
The Encoder Buffer Unit is designed to be mounted in an electrical
cabinet via its integral mounting feet. For all applications, this
installation method should be observed. Before powering up your
Encoder Buffer Unit, make sure it has been configured correctly and
that all peripheral equipment has been correctly connected to it.
WARNING
!
A feedback loop must not be closed via the
Encoder Buffer Unit. Use of this Buffer in the
feedback path of a position controller disables any
"encoder loss" detection function which can cause a
runaway condition.
Failure to observe these warnings will cause
unexpected and/or uncontrolled movement of
peripheral equipment. This may cause damage to the
equipment and to your health and safety.
WARNING
!
Do not apply power to your Encoder Buffer Unit
when it is part of a control system without first
establishing that this will not have any adverse
effects.
Do not make or break any electrical connections to
your Encoder Buffer Unit while power is applied.
Do not change any selection link settings on your
Encoder Buffer Unit while power is applied.
Failure to observe the above warnings may cause
damage to the follower unit, unexpected and/or
uncontrolled movement of peripheral equipment
and your health and safety.
