Connection points
Single point purging setup is possible (Fig. 9) i.e.
no solenoid valves with the Danfoss IPS 8 unit.
This kind of installation should be installed as
shown in Fig. 9 i.e. above the receiver or using a
float valve. (See section on connection locations).
For single point purging as in Fig. 9, the setting in
the MCX for the number of valves to ‘0’ or switch
off the multi-purging functionality in the general
setup (Parameter Name: Activate Multipurger).
As factory default, the Danfoss IPS 8 is configured
to handle 8 purge points (Fig. 10). The correct
amount of purge points connected needs to
be setup in the MCX controller after power-up.
Both power and control wiring of the installed
solenoid valves coils should take place prior to
first power up.
Multi-point purging
NEVER HAVE MORE THAN 1 PURGE POINT
OPEN AT A TIME.
Always close one purge valve before opening
the next.
This is done by turning the purger unit power
on (Parameter Name: Activate Multipurger) and
entering the number of actual purge points
in the program. See section “Programming/
configuration”.
