Interface XS2
The interface serves as a connection between the system and external
devices. The functions are described in detail in the manual Control System
CS 20 for Bulk Melters, section Central Module with Digital Input/Output.
NOTE: It is essential to bridge Pin 9 with Pin 1 (24 V
DC
) before initial startup.
Also refer to plug connection diagram Interface XS2 for BM 20 (wiring
diagram).
NOTE: To conform with a European standard regarding electro‐magnetic
compatibility, only shielded cable may be connected. The shield
must be
connected to ground in compliance with the standard (PE connection in plug
connector).
NOTE: Inductive loads (e.g. solenoid valves) connected to the system must
be equipped with a protective device (e.g. recovery diode) that disables the
inductive voltage generated when an inductive load is switched off.
