General
Infilex ZM (Infilex: named for “Infinity” and “Flexible”) Model
WY5122, integrated into savic-net FXBMS (building
management system), manages remote units (also called
sub-controllers), such as Infilex VC, Infilex FC, and Infilex
SC.
Up to 50 remote units can be connected. Infilex ZM can
control these units separately as well as per group.
Infilex ZM communicates with the savic-netFX center unit
through the transmission trunk line NC-bus and with the
remote units through the transmission trunk line SC-bus.
Features
Compact design:
Small size body ensures space saving.
Installation:
A quick-fit screwless (clamp) terminal block is used for
the communication terminal block of the I/O module,
ensuring the labor saving of the wiring work.
Additionally, either DIN rail mounting or screw mounting
can be selected.
Management of remote units:
Infilex ZM manages up to 50 connected remote units
(Infilex VC, Infilex FC, Infilex SC, etc.), allowing ON/OFF,
failure monitoring, measuring, and setting individually
from the BMS center unit. Infilex ZM can perform such
managements of remote units by group and is applicable
to any group configuration consisting of up to 50 units of
Infilex VC and Infilex FC. Additionally, Infilex ZM
provides flexible management. For example, group
ON/OFF can be commanded even when individual
measuring is commanded.
Risk diversification and high-speed supervision:
Infilex ZM has 50 programs of time schedules, analog
alarm monitoring, and runtime/cycle-count integrating in
order to manage the connected Infilex VC, Infilex FC,
Infilex SC, etc. This achieves diversification of risks and
high-speed supervision of BMS.
One Infilex ZM controls up to 4 sets of VAV (VAV:
variable air volume, controlled by Infilex VC) and AHU
(controlled by Infilex GC). Load reset control of supply
air temperature, fan speed control, interlocking operation
are available. Additionally, the mixing loss control of the
interior VAV and perimeter FCU (fan coil unit) can be
performed.
Support functions:
Infilex ZM supports to adjust VAV by setting the
max./min. air volume levels of all VAV units included in a
specified set. Infilex ZM also supports to adjust
AHU/FCU flow rate and to flush the piping by fully
opening and closing all the valves that the Infilex ZM
controls.
CE Marking certified product:

Wiring
Wiring from power supply to terminal block
Attach the crimp terminals for the M3 screw terminal
block to the wire ends, and connect them to the terminal
block.
Wiring to the NC-bus Terminal Block
Since quick-fit screwless terminal block is used for the
NC-bus terminal block, the procedure for wiring is
specified as follows.
1) Strip the wire sheath 8 mm. (The gauge for the strip
length is located at the front lower part of Infilex ZM
main unit. If the stripped part is longer than 8 mm, the
conductor will be exposed, causing electrical shock or
short circuit between adjacent terminals. If it is shorter,
the conductor may not contact the connector.)
2) Make sure that no wire fiber is protruded from the
stripped conductor.
3) Press the button on the terminal block deeply enough
to insert the wire using a slotted screwdriver.
(Maximum button-pressing force is 14 N {1.4 kgf}.)
4) Release the button, and gently pull out the wire to
make sure that it is tightly fastened. (If you pull out the
wire diagonally, it may be disconnected.)
Make sure that no wire fiber is protruded from the
stripped conductor.
Precautions for connected cables
Neatly place the cables connected to Infilex ZM so as
not to hide the parts shown in Fig. 8.
Make sure there is no slack in the wires from the cable
ducts to Infilex ZM.
Figure 8. Connected wires in position
System indication label for the controller number
The indication tag has the system indication label on its
back.
Turn it over and fill in the controller number on the label.
Figure 9. System indication label
Protective sheet
After wiring installation, be sure to peel off the protective
sheet before turning on the power.
1) Adhesive is applied to the sheet approximately 20 mm
from the front edge. Peel off this area.
2) Tear off the sheet along the perforations.
Figure 10. Protective sheet
Tube marker
Since Infilex ZM adopts quick-fit screwless terminal
block for communication, communication cables are
connected to the terminals without crimp terminal lugs.
Therefore, if normal tube markers are used, they may
come off when the cables are disconnected. To prevent
this, use the Flat Tube Marker. It is held on a cable by
friction and thus does not come off easily.
