Utilisation
This cogeneration switchgear is equipped with a
control, output and auxiliary drive component and it is
factory-tested together with the cogeneration module.
The customer only has to connect the power cable
(power current 400 V) of the standard version to the
main low-voltage distribution. The outgoing cable unit
should be secured with fuses and the customer should
provide a contact for selecting or deselecting with the
standard version that selects or deselects depending
upon heat or power needs. Then the cogeneration
module is automatically started by the internal
cogeneration switchgear, switched to the mains and
adjusted to the set or specified load output. The load
adjustment can be either specified by an external
analog signal (0/4
–20 mA) or changed right on the
cogeneration module. If there are malfunctions, the
cogeneration module turns itself off automatically and
the centralised fault indication is available potential-
free for passing onto any control equipment of the
customer. The customer then has to provide space
ventilation and a heating water pump control system
and return temperature increasing mechanism should
also be provided. The pump is requested through a
potential-free contact from the switchgear. The return
control valve is supplied with 24 V~ and triggered with
a 0
–10-V signal.
