Troubleshooting
Make sure the cable length value is less than the value calculated on the right
side of the equation. For example, a Cresnet run using 18 AWG Crestron
Certified Wire and drawing 20 watts should not have a length of run more than
333 feet (101 meters). If Cresnet HP is used for the same run, its length could
extend to 1250 feet (381 meters).
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs.
One twisted pair is the 24 and G pair and the other twisted pair is the Y and Z
pair.
Strip and Tin Wire
When daisy chaining Cresnet units, strip the ends of the wires carefully to avoid
nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector and tin the twisted connection. Apply solder only to the
ends of the twisted wires. Avoid tinning too far up the wires or the end becomes
brittle. Insert the tinned connection into the Cresnet connector and tighten the
retaining screw. Repeat the procedure for the other three conductors.
Add Hubs
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the number of
Cresnet devices on a network exceeds 20 or when the combined total length of
Cresnet cable exceeds 3000 feet (914 meters).
PROBLEM INSTALLATION RESOLUTION HARDWARE RESOLUTION SOFTWARE RESOLUTION
Occupancy
sensor does not
function.
Verify that the occupancy sensor is
placed in the correct location by utilizing
the Test mode on the sensor. For
additional details refer to the occupancy
sensor’s installation guide at
www.crestron.com/manuals.
Verify the occupancy sensors are
connected correctly. If sensors are
connected via GLS-SIM, verify that DIP
switch settings match those listed in this
guide.
Verify that occupancy sensors are associated with loads
from the “Occupancy Sensor” screen.
Photo sensors do
not function.
Verify that the photosensor is placed in
an area where natural light is changing.
Verify the photo sensors are connected
correctly. If sensors are connected via
GLS-SIM, verify that DIP switch settings
and dials are correct.
Verify that photo sensors are associated with loads from the
photo sensor setup screen.
Verify that the photo sensor levels are set such that actions
occur with the level of natural light incident to the sensor.
Verify that Auto mode is triggered by an external device.
Keypad buttons
do not trigger the
expected action.
Verify that the Cresnet wiring is in place
and that adequate power is being
supplied.
N/A Verify that the keypad buttons have been programmed from
the keypad programming screen.
Verify that the loads are in a condition where they would
change from a keypad button press. For example, the loads
are off if the keypad action turns on the load.
Timeclock events
are not occurring.
N/A N/A Verify that timeclock events are programmed properly.
Ensure that there are no timeclock overrides present.
Verify that the date and time of the GL-IPAC-SW8 are set
correctly.
Contact closures
do not function.
Verify that the contact closure is being
triggered.
Verify that the contact closure wires are
being connected to the contact closure
input and to the ground terminal.
Verify the contact closure input is programmed via the
“Contact Closure” screen.
Verify that the contact closure is capable
of sinking 10 mA of current and it does
not provide current to the input terminal.
A city is not
available from
the “Project
Settings” screen.
N/A N/A Select a city that is geographically close and in the same
time zone as the current city. The location selection allows
for accurate calculation of sunrise and sunset times.
Selecting a nearby city may cause the sunrise and sunset
times to be off by a few minutes.
External loads
are not being
controlled.
Verify that the modules attached to the
GL-IPAC-SW8 are supported. Refer to
“Accessories” on page 13 for a list of
supported devices.
Verify that Cresnet wiring is properly
wired between the GL-IPAC-SW8 and
the external panel. Verify that the
modules within the panel are wired
properly. Refer to “Wiring Diagram” on
page 2 for wiring information.
Verify th
at the modules IDs have been properly set
according to the “Panels” setup option.
Use the Right Wire
To ensure optimum performance over the full range of the installation topology,
use Crestron Certified Wire only. Failure to do so may incur additional charges
if support is required to identify performance deficiencies because of using
improper wire.
Calculate Power
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure
to do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead
to unpredictable results or damage to the equipment. Use the Crestron Power
Calculator to help calculate how much power is needed for the system
(www.crestron.com/calculators).
When calculating the length of wire for a particular Cresnet run, the wire gauge
and the Cresnet power usage of each network unit to be connected must be
taken into consideration. Use Crestron Certified Wire only. If Cresnet units are
to be daisy chained on the run, the Cresnet power usage of each network unit
to be daisy chained must be added together to determine the Cresnet power
usage of the entire chain. If the unit is run from a Crestron system power
supply network port, the Cresnet power usage of that unit is the Cresnet power
usage of the entire run. The wire gauge and the Cresnet power usage of the
run should be used in the following equation to calculate the cable length value
on the equation’s left side.
