Danfoss VLT 5000 Serie Instruction Seite 7

Instruction for 5V to 24V converter for VLT5000
encoder inputs.
The converter is used to connect an encoder with 5V
differential signal (Linedriver/RS 422) to the 24V
inputs on the VLT5000 control card.
The converter has a 5V Linedriver output so that the
encoder output signal can be used by other
equipment parallel to the VLT5000.

The Application Option Card as well as other electronic components within
the VLT are susceptible to Electrostatic Discharge - ESD. Make sure that
the option card remains in the ESD protective bag at all times during trans-
portation and storage. Before you take the card out of the protective back for
mounting, make sure that you are properly connected to common ground, for
example by means of a ground-connected wrist-band, and that the same
applies to the VLT. When the option card is out of the protective bag, you
should only touch the rim, and never touch the electronic components, as
they may suffer irreparable damage.
VLT ® Series 5000 5V TTL -> 24V DC Option
There is a 5V input which is driving a relay with a
normally open switch. This input can be used for a
ready or fault output from the encoder and the relay
swich can for example be connected to one of the
digital inputs of VLT5000.
The card is mounted behind the VLT 5000 control
card like other option cards.
