VERY IMPORTANT - PLEASE READ
MOST COMMON ISSUES ENCOUNTERED DURING INSTALLATION
Polara’s 2-Wire Accessible Pedestrian System transmits power
and data
between the iCCU Central Control Unit and each
Push Button Station (PBS). It is not simply voltage/power carried over the PBS wires. This equipment must be wired
correctly, and the wiring must be of good quality for data to transmit properly. The following are the
most common
problems
installers experience when installing Polara’s 2-Wire system. Please read the items listed below, then thoroughly
read the attached Quick Start Installation Guide and make sure each step is understood before proceeding.
1.
PROPER WIRING:
A.
Never apply 120 VAC to a PBS, ICB or iCCU terminal block. This will cause damage and void the warranty.
B.
For proper operation, a dedicated pair of #14 or #12 AWG wire is required between each PBS and the Interconnect
Board (ICB) / iCCU to ensure good communication. It is not recommended to share button wires between buttons.
2.
PROPER POWER UP SEQUENCE:
A.
DO NOT CONNECT AC POWER TO THE iCCU UNTIL INSTALLATION OF ALL SYSTEM WIRING IS COMPLETE!
B.
Once all cabinet wiring is complete and all PBSs are mounted and connected to the button wires, power up the
iCCU-S2 by connecting the power cord to the iCCU-S2 AC inlet, or if using an iCCU-C2, slide it into the rack.
C.
Each PBS should beep, and then after a short time, its LED should flash with a 2-flash sequence, while the PBSs
attempt to communicate with the iCCU. Once a PBS is communicating with the iCCU, it will begin to flash in a four-
flash pattern.
D.
If any PBS continues in a two-flash pattern, this indicates the PBS has not established communication with the
iCCU. Typically, this is corrected by changing the communication channel. See Advanced Communications, Settings
Sections 5.3 (iOS App) in the iNS2 System Manual (or Section 1.3 in Android manual) before proceeding with
system setup. The manual is available in the Field Service apps, or on our website
www.polara.com
.
***(Do not
change the gain settings)
*** If changing the channel does not bring a PBS out of a two-flash pattern, contact
Polara Tech support for assistance @ 903-366-0300 EXT 4 or 888-340-4872.
ALL buttons must have a four-flash
pattern to proceed with setting up the system
.
E.
If installing an iCCU-C2 and there is a two-flash sequence on
all
buttons, verify wiring complies with that shown in
the iCCU-C2 Quick Start Guide or Section 3.3 of Manual.
3.
PASSWORD ISSUES
: The iCCU can be connected to thru Wi-Fi. The buttons can be connected to thru Bluetooth.
A.
Once Wi-Fi is turned on at the iCCU, the Wi-Fi password is
DEFAULT1
(ALL CAPS).
B.
Following power up, each button will say “change password” every 30 seconds, until the default password is
changed. There is one shared password for logging into an iCCU and all PBS connected to it. The factory default
password is
1234
. Using a Field Service app, use 1234 to log into the iCCU or any PBS the first time, and change
the password. This changes the password for all PBS and the iCCU. See Section 5.2 in the Manual for details.
C.
If the password is unknown,
a
Password Reset
requires a call to Polara Tech Support.
4.
iCCU and PBS FIRMWARE VERSIONS:
A.
The system will not work properly if it does not have the latest, or correct firmware. Once the system is powered
up and operating,
the firmware must be upgraded
to the latest version,
first on each PBS
, then on the iCCU using
the Polara Intelligent Config PC app, or the Polara iOS / Android Field Service apps.
UPGRADE BUTTONS FIRST
5.
CHANGING SYSTEM SETTINGS:
A.
A button can be logged into to change its settings. If desired, those settings can be uploaded to all buttons.
6.
Operating in BIU/SDLC mode
:
A.
A connection from the iCCU-S2 to the Traffic Controller’s Logic Ground must be established using a Polara
manufactured SDLC cable because standard SDLC cables do not pass through Logic Ground connections.
Polara
offers a straight SDLC cable with an external ground wire, or a “Y” cable with internal ground.
If a Polara made
SDLC cable is not used, then the CABLE-C-LG supplied with every iCCU-S2, must be used. Not doing this can
cause damage to the iCCU and other equipment connected to the SDLC bus. Request document 350-079 for
details.
If you have questions, or encounter issues during installation, call our Tech Support line at
888-340-4872
between 7:30
AM and 5:00 PM CDT/CST.
