PCD7.LR-TR40 and PCD7.LR-TR42
LCD and non-LCD Wall Modules
BEFORE INSTALLATION
Fig. 1. PCD7.LR-TR42
Mount the wall module on an inside wall approximately 1372 mm
from the oor (or in the specied location), to allow exposure to
the average zone temperature. Do not mount the wall module on
an outside wall, on a wall containing water pipes, or near air ducts.
Avoid locations that are exposed to discharge air from registers or
radiation from appliances, lights, or the sun.
The wall module can be mounted on a wall, on a standard utility
conduit box using 3.5 mm screws or on a 60 mm wall outlet box
(see Fig. 3). When mounting directly on a wall, use the type of
screws appropriate for the wall material.
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can intro-
duce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive loads such
as motors line starters, lighting ballasts, and large power distribu-
tion panels.
Shielded cable is required in installations where these guidelines
cannot be met.
Ground the shield only to the grounded controller case.
IMPORTANT
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring dia-
grams.
• For information on Sylk bus distance limitations,
see Table 1 on page 2.
• All wiring is polarity insensitive.

aFor the congurable PCD7.LRxx it can only connect 1 wall module to
the controller. For the programmable PCD7.LRxx-P5 please refer to
the PCD7.LRxx-P5 manual for the maximum quantity of wall
modules which can be connected to 1 controller.
bAs a rule of thumb, single twisted pair (2 wires per cable only),
thicker gauge, non-shielded cable yields best results for longer runs.
c The 30 m distance for standard thermostat wire is conservative, but
meant to reduce the impact of any sources of electrical noise
(including but not limited to VFDs, electronic ballasts, etc). Shielded
cable recommended only if there is a need to reduce the eect of
electrical noise.
dThese distances also apply for shielded twisted pair.
All terminal connections can be made to the backside of the
module. There are no eld adjustable/replaceable components
inside the module.
Attach the wires from the programmable controller and network
to the appropriate wall module terminals, as indicated in Fig. 6 on
page 3.
CAUTION
Improper Electrical Contact Hazard.
Screw-type terminal blocks are designed to accept no
more than one 2.5 mm2conductor.
Connect multiple wires that are 2.5 mm2with a wire nut. Include a
pigtail with this wire group and attach the pigtail to the individual
terminal block.
Wiring Wall Modules
Wire the terminal block shown in Fig. 6 as follows:
1. For single wires, strip 5 mm; for multiple wires going
into one terminal, strip 13 mm insulation from the
conductor. See Fig. 5 for wiring multiple PCD7.LR-TR4x.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
3. Review and verify the terminal connection wiring
illustrated in Fig. 6.

Each wall module on a Sylk bus must use a dierent bus address,
and there may be multiple PCD7.LR-TR4x wired on a single Sylk
bus. To change the bus address of a wall module, adjust the
address dipswitches to match that of the desired bus address
(1-15). Use the bus address label, shown in Fig. 7, as a reference.
The default address for both PCD7.LR-TR40 and PCD7.LR-TR42 is 1.
The address on the wall module must match the address in the
conguration tool.
Setting the Wall Module Bus Address Dial
Fig. 7. Bus address settings label.
When all wiring is complete, hook the top side, and then snap
down like on a hinge. See Fig. 8.
Attaching the Wall Module to the Subbase
To remove the wall module from its subbase:
1. Locate the two snaps on the bottom of the IFC .
2. Push a screwdriver into each snap to release the IFC
from the subbase.
3. Pull the wall module up and away from the subbase.
See Fig. 8.

After the wall module is properly wired to the controller, it will
power up. Upon initial power up, the wall module’s LCD panel
displays three screens for two seconds each, shown in Figs. 9-11,
while the conguration le is being loaded. Once the congura-
tion le has been loaded and the startup screens have cycled
through, the LCD panel will then display the home screen. If these
screens continuously cycle, this indicates there is no program
downloaded to the controller, or the bus addresses don’t match
between the wall module and the PG5 cong tool.
