Operation Of The Switchgear - Wilo Control EC-Fire Einbau- Und Betriebsanleitung

Output for an external signalling unit
Depending on the application of the switchgear,
the parameters of a 24 V (DC) output for an exter-
nal signalling device can be set as follows
(menu 5.67):
• "off": deactivated – no warning function
• "Error": the output is activated when a fault occurs
in the system
• "Run": the output is activated when at least one
pump is running
Fieldbus connection
The switchgear is prepared for connection via
ModBus RTU as standard. Connection is estab-
lished via an RS485 interface (electrical connec-
tion as per section 7.2.12).
The switchgear works as a Modbus slave. Basic
settings are made in menus 2.01 to 2.05.
Different parameters can be read and also
changed to some extent via the Modbus interface.
An overview of individual parameters and a
description of the data types used are shown in
the appendix.
