as needed. Secure the button diaphragm in the correct orientation by tightening the two retaining screws with a Phillips-head screwdriver.
Please use caution as the metal button diaphragm is sharp.
Remove the electronics module and speaker module together from the
backplate.
8. Position backplate on pole at correct height and orientation so arrow points to ending of crosswalk on the opposite side of the street.
Orientation is very important because a blind person uses the arrow and face of the sign to orient themselves to the direction of travel. Mark
mounting bolt locations if existing holes not correctly located. MUTCD max. height is 48”. Typical recommended height is 42”, but can be
lower. Drill and tap ¼-20 bolt holes and wire access hole (if necessary, see
Step 6
).
9. Position the backplate against the pole and route the wires forward near the bottom end of the backplate. Position the wire such that 3 or 4
inches of wire is available at the bottom of the backplate.
10. Attach the backplate to the pole using the provided ¼-20 bolts with washers.
11. Re-install the electronics/speaker modules. Re-install the sign (and sign backplate if using), securing the PBS Module in place before wiring.
Re-install EARTH GND (ground) connection screw to location between terminal blocks.
12.
Connect the two wires from the traffic signal cabinet to the terminals of the larger black terminal block labeled BUTTON/PLC. Wire polarity is
not important. Recheck tightness of all connections. Re-install the lower cover.
13.
Remove two ped isolators from Input File and replace with iCCU-C2. The two ped isolators that will be removed are normally located in
slots I-12 and I-13. In this case, the iCCU-C2’s card edge needs to be installed in slot I-13. The iCCU-C2’s card edge always needs to be
installed into the odd-numbered slot, to be able to use all 4 channels. Connect 15 pin cable of C4 Cable adapter to front of iCCU-C2.
14. Once all cabinet wiring is complete and all PBSs are mounted and connected to the button wires, power up the iCCU-C2 by connecting the
power cord to the iN2-150WPS-C’s AC inlet. Each PBS will beep, then it’s LED should blink in a four sequence pattern. If any PBS flashes
in a two sequence pattern, this indicates the PBS has not established communication with the iCCU-C2. See Advanced Communications
Settings, Sections 5.3 (iOS App), in the iNS2 System Manual before proceeding to step 9.
Note: Wi-Fi default password is “DEFAULT1” (all caps, no quotes), iNS2/iCCU-C2 default password is “1234”.
15.
The first step is to update the firmware on each PBS. For each PBS, connect to the PBS and perform a firmware update. See Section 8.1 of
Manual if using the iOS app. The PBS will reset after the firmware upgrade is completed.
16.
Next, connect to the iCCU-C2 and perform a firmware update. See Sections 5.1 and 8.1 of Manual if using the iOS app. The iCCU-C2 will
reset after the firmware upgrade is complete.
17. Each PBS will play the message “Change Password” until the password is changed. It is now necessary to change the password and
perform channel and PED phase setup of the iCCU-C2. Use the iNS2/iCCU-C2 default password as the “Current” password. See Sections
5.2-5.4 of Manual if using the iOS app.
18. Once the channel and phasing is set for the iCCU-C2, each PBS must be assigned to a phase. See Section 5.5 of Manual if using the iOS
app.
19.
Once each PBS phase is assigned, the settings of each PBS can be configured as needed. See Section 6 of Manual if using iOS app.
Advanced Communications Settings
All iNS2 PBSs connected to the interconnect board communicate with the iCCU-C2 via the field wires, using one of two communication
channels, A or B.
The iNS2 PBSs and the iCCU-C2 need to be on the same channel in order to communicate with each other. Anytime an iNS2 PBS is powered
and electrically connected to an iCCU-C2 but is not communicating with the iCCU-C2, the iNS2 will automatically perform a recalibration.
The iNS2 will recalibrate by resetting itself, identifying the correct communications channel, and adjusting its signal until it establishes
communication with the iCCU-C2. This process typically takes 1-3 minutes. Once calibrated, each iNS2 will save its communications settings
in non-volatile memory and use them during any subsequent restart. Once a PBS’s communications settings are calibrated and it makes
a successful connection to the iCCU-C2, it will flash its pilot light in a four flash pattern. This four flash pattern will continue until the PBS is
assigned to a phase that is receiving pedestrian Walk, Don’t Walk, or Clearance intervals.
There may be field conditions that make one communication channel work better than another. Upon installation, customers should place calls
and observe proper operation during at least 3 full ped cycles. Next, connect to any iNS2 and confirm that the health log of every other iNS2
and the iCCU-C2 can be read without error. If either of these steps fail, try the other communication channel. It is only necessary to change
the channel of the iCCU-C2, as the iNS2 PBSs will automatically configure to the appropriate channel. To change the communication channel
on the iCCU-C2 with the iOS App: from the main menu, choose Advanced Options, then Communication Settings. Next, select Channel A
or Channel B, and then Save. Make sure the target device is the iCCU and not an iNS2. Within a few minutes, all iNS2 PBS devices should
establish a connection to the iCCU-C2.
If any PBS exhibits a two flash pattern, see Advanced Communications Settings, Sections 5.3 (iOS App), in the iNS2 System Manual.
Because of the various types and states of field wiring, PLC communication may not work in all field wiring conditions, so Polara cannot
guarantee an iNS2 system will work on all intersections. If the steps in the Advance Communications Settings Sections of the iNS2 System
Manual fail in establishing reliable communication between a PBS and iCCU-C2, a 3-Wire system is the only option.
