Device Configuration And Commissioning - Horstmann ComPass B Instructions For Use Manual

Dipl.-Ing. H. Horstmann GmbH
Important note for the connection of the external input (see Table 2)
• For activation of the functions use potential-free contacts, e. g. coupling relays or tra-
cers.
• Use separate potential-free contacts for each indication device.
• If the functions of several devices shall be operated in parallel, the triggering disconnec-
ting elements (relay outputs, coupling relays etc.) are to be operated in parallel.
• Operational earth or other "GND" potentials are inappropriate as common reference po-
tential.
• Use a momentary contact for triggering (momentary time 1-5s), but not a permanent
contact.

Device configuration and commissioning

5.1. Device configuration
ComPass B is delivered with a standard factory setting (see Appendix A) which, in most cases,
meets all requirements. Some parameters (see Table 5) however need to be set and checked indi-
vidually which can be carried out either via the front panel control or the RS485/MODBUS interface.
Any alteration in the configuration should be carried out while assuring that the ComPass B is
supplied by an external supply, otherwise parameter storage may fail.
