XC77 • XAC77 - Encoder ATEX
5.8 XAC77 with analogue output
ATEX encoders with analogue output are based on the EM58 PA series programmable encoders,
thus refer to the transmission specifications described in the enclosed EM58 PA manual;
differences, if any, are described below. Furthermore they need the programming interface tool for
configuration. User's manual and programming file are available at the address:

Description

” 0Vdc Analog “ signal is internally connected to 0Vdc.

Preset:
Data latch in memory (active high for at least 100 ms).

Counting Direction: set counter clockwise (active high).

Fault:
Open collector signal for cable integrity check (only current output).
To connect fault signal refer to Figure 2 and Figure 3, pay attention to the value of R2.
No enc. error = transistor ON (in conduction).
Encoder error = transistor OFF (open).
