WW400 Product Level Document Overview

Manual

Introduction

Before installation, thoroughly review the WW400 LEVEL 1 System Planner which will familiarize you with the features, operation standards and installation procedures of Carmanah’s WW400 system. Failure to comply with the use, storage, maintenance, installation, or placement instructions detailed in that document could void the warranty. WW400 documentation is also available online at support.carmanah.com. After reviewing the LEVEL 1 System Planner, this document is the next step to installing your WW400 system.

First, install the WW400D and WW400S systems using this guide; then, move on to the following items:

• LEVEL 3 solar options (where applicable)
• LEVEL 4 configuration guides

The WW400S is installed following Carmanah E/F Series product manual. Specific instructions pertaining to the WW400D detector pole are detailed in this section.

• Batteries are shipped fully charged. Use extreme caution when handling batteries as they can generate hazardous short-circuit currents. Remove all jewelry (bracelets, metal-strap watches, etc.) before handling batteries
• Electrical shock hazard. Do not let battery terminals contact any exposed metal. Do not connect battery and solar panel harnesses until all system wiring is completed.

Pole Preparation

1. Mark the positions of the cabinet, cameras, radar and flashing LED sign (if installed) on the pole.
2. Drill a 1-3/4″ dia. hole at the desired position of the cabinet nipple.
3. Drill 1-3/4″ holes for cable exit/entry points near the radar, cameras and if used, flashing LED sign. These holes allow the sealing connectors to clear and permit fishing harnesses from either end.
4. Fish the camera Ethernet and ground harnesses between the cabinet hole and camera hole(s). Ensure the sealing boots on the Ethernet harness and the larger sealed ring terminal on the ground harness are at the top of the pole.
5. Fish the radar Ethernet harness between the cabinet and radar hole, ensuring the sealed bayonet connector is at the top of the pole.
6. If used, fish the harnesses between the cabinet nipple hole and flashing LED sign hole.

Cabinet Installation
Follow the Carmanah G Series cabinet installation detailed in Section 3 of the G Series product manual. Solar-powered WW400D systems use a separate solar power unit. Do not use the solar panel connections within the detector pole controller cabinet located the Carmanah EMS cover plate.

Camera and Radar Controller Connections

The WW400D controller includes network ports for Local Area Network (LAN), Intersection and Freeway cameras, and radar. The controller also includes two test buttons: one for testing LED sign(s), and one to initiate a full violation test, including remote alert and sending video confirmation packages. Three status LEDs indicate the state of the controller. See Section 4 in the LEVEL 1 System Planner for further details.

1. Once the system is wired to its power source, connect the camera grounding wires to the grounding terminal at the top-left corner of cabinet, ensuring any existing ring terminals remain in place. Secure grounding wires in two places as shown, ensuring all slack is removed so wires do not get pinched inside the door gap. The camera ground wire in the cabinet has the smaller #8 ring terminal
2. Connect the RED-labelled radar ethernet cable to the Radar SPD.
3. Connect the BLUE-labelled Freeway camera ethernet cable to the Freeway Camera SPD.
4. Connect the YELLOW-labelled Intersection camera ethernet cable to the Intersection Camera SPD.
5. Use the cable ties to strain relieve cables to the provided features.

• Caution : Avoid tightening network cable ties to the point where they deform the ethernet cable jacket as this may cause damage the network cables resulting in loss of communications.
• Caution : Connecting the radar cable to a camera port will result in damage to the radar unit due to the different operating voltages.

Radar Installation

Mounting Height and Tilt Angle
The mounting height and vertical tilt angle of the radar affect the detection distance and overall performance of the radar. The typical mounting height is 18 to 25ft above grade with tilt angle parallel to the grade of the road. The angle can be adjusted based on local conditions depending on distance from front of zones and required viewing distance. Do not tilt the radar downwards more than 2 degrees relative to grade.

Offset Angle
The radar should be aimed at the center of the detection zones but parallel to the road grade. The “gun sights” on top of the radar body can be used to accurately aim the radar. The bracket assembly should be mounted on the side of the pole so that the pole does not impede the ability to use the sights.

1. Detach the radar from the bracket by removing the bolt. Discard the bolt. Keep the lock washer for re-use.

2. Mount the bracket to the pole, with the flat face of the bracket 5″ above the center of the harness entry hole.

3. Mount the stiffening bracket so it touches the top bracket, and the mounting holes align.

4. Place the lock washer on the supplied longer bolt and mount the radar through both brackets as shown.

5. Adjust the lateral aim of the radar before tightening the bolt in the bottom of the bracket.

6. Adjust the up/down aim of the radar and tighten the horizontal bolt.

7. Lead the connector through the grommet on the upper bracket and connect the radar Ethernet harness to the radar, ensuring the bayonet connector is fully engaged and locked in place.

8. Secure the cable to the lower bracket in two places using the cable tie features in the bracket as shown and ensure the harness does not chafe on the edges of the harness entry hole in the pole.
   Radar angles may need to be adjusted during system commissioning as detailed in LEVEL 4 configuration guides. Connecting the radar to a camera port will result in damage to the radar unit due to different operating voltages.

9. Connect the 25ft Ethernet cable labeled “RADAR” to the radar then route it into controller cabinet and install into the controller port with the corresponding color.

Camera Installation

The Freeway and Intersection cameras are pre-configured uniquely and must be physically installed in the correct locations and connected to the matching ports on the controller.

1. Install the camera brackets on the pole below the radar. The recommended height above grade is 16ft.
2. Tighten banding as per banding manufacturer’s instructions. Camera brackets can also be drilled and through-bolted if desired. Brackets are made of stainless steel and are more difficult to drill than mild steel or aluminum.
3. Aim the camera brackets in the approximate mounting direction and tighten the 7/8″ nut used for panning adjustment with a box wrench and 7/16″ tilt adjustment screws. Fine-tuning of camera aim can be performed when mounting the camera pan/tilt base plate.
4. Install camera pan/tilt base plates and mount the cameras to their respective brackets with included bolts.
5. Connect the 25ft Ethernet cable labeled “FREEWAY” to the Freeway camera, apply dielectric grease to the connector, then install the cable seal using the two attached screws. Once connected to the camera, route the cable into the controller cabinet and install it into the corresponding SPD port.
6. Connect the 25ft Ethernet cable labeled “INTERSECTION” to the Intersection camera, apply dielectric grease to the connector, then install the cable seal using the two attached screws. Once connected to the camera, route the cable into the controller cabinet and install it into the corresponding SPD port.
7. Strain relieve the camera harnesses to the camera mounting arms and ensure harnesses do not chafe or rub anywhere.
8. Connect the two (2) camera ground cables to each camera as shown and route to the ground location in the controller cabinet. Secure the ground cables in the control cabinet with cable ties as indicated.
9. Aim the Intersection camera so that it is aimed at the area monitored by the radar detection zones. Refer to in LEVEL 4 configuration guides for camera operation instructions.
10. For optimum performance, the Freeway camera should be aimed so that wrong-way traffic crosses the camera frame diagonally. The camera should be aimed approximately 20 degrees from the vehicle travel direction and titled down towards the center of the path.

Note : Camera aim will need to be calibrated during system configuration on-site.

Maintenance and Product Care

The WW400 systems are designed to operate reliably for years with minimal maintenance. See Carmanah E/F and G Series product manuals for general product maintenance guidelines.

In addition, a periodic visual inspection of the cameras is also recommended. This should include:

• Visual inspection of cables, connectors, waterproof boots and sealing surfaces
• Check mounting fasteners are tight
• Status indicator lights
• Camera lenses are clear, free of moisture evidence or debris
• Checking for damage to bracket or camera body, cracked case, bent bracket, etc. The frequency of the inspections depends on location and local weather patterns. A yearly visual inspection of the system is typically sufficient. The system is designed to be maintenance-free, but maximum system performance is achieved when fixtures, camera lenses and solar panels are clean. When inspecting the controller cabinet interior, ensure that the vent screens are undamaged and that the vents are clear and allow airflow. Below are some preventative maintenance guidelines.
• Clean cameras – annually or as needed
• Camera aiming (check) – annually or as needed
• Radar aiming (check) – annually or as needed
• Check UPS battery health – annually
• UPS test (local) – 6 months
• Flasher test (local) – 6 months
• Violation test (local) – 6 months
• System test (remote) – daytime
• System test (remote) – nighttime
• System reboot during annual inspection

WWD580 Replacement

1. De-energize the system via the main breaker in the controller cabinet.
2. Disconnect the white network cables from WWD580.
3. Loosen the two WWD580 cover retaining screws and slide the cover to remove it.
4. If replacing the relay board as well as the TS2 board, disconnect the 4x wires from the top board section.
5. Remove the 8x screws with a Philips screwdriver to separate both boards from the mounting bracket.
6. Ensure the thermal transfer pad is in place on the mounting plate; replace if necessary.
7. If replacing the relay board, reconnect the four wires to the new relay board:
   • a) Black wire: GND terminal
   • b) Red wire: 12v terminal
   • c) Blue wire: R1-COM
   • d) Grey wire: R1-NO
8. Connect the relay board and TS2 (main board) if previously disconnected.
9. Install both boards and the 8x retaining screws.
10. Replace the cover and secure in place by tightening the 2x cover screws.
11. Reconnect the network cables, ensuring the correct order is followed.
12. Re-energize the system and check functionality after startup sequence is completed.

Caution : Avoid tightening network cable ties to the point where they deform the Ethernet cable jacket as this may cause damage the network cables resulting in loss of communications.

Uninterruptible Power Supply (UPS) Battery Replacement
The battery installed in AC systems acts as a UPS; it is a 12V battery with a capacity of 1.2Ah. When installed correctly and connected to power it can stay in the float state of charge indefinitely. Use a load tester every 12 months to verify the health of the battery.

In the event the battery needs to be replaced, use the following steps:

1. De-energize the system.
2. Disconnect the negative (-) battery harness from the negative terminal of the battery.
3. Disconnect the positive (+) battery harness from the positive terminal of the battery.
4. Cover the battery terminals with tape to prevent shorting them on the chassis.
5. Cut the cable ties that hold the battery in place.
6. Remove the battery and dispose of it appropriately.
7. Route new cable ties into mounting holes on power plate.
8. Install new battery noting orientation of terminals and secure with cable ties.
9. Energize system.
10. Connect the positive (+) battery harness from the positive terminal of the battery.
11. Connect the negative (-) battery harness from the negative terminal of the battery.
12. Verify all system status lights are correct as per labeling. The backup battery must be disconnected before shutting off the breaker in order to power down the system. Failure to do so will cause the UPS to energize and potentially drain the battery to damaging levels if left connected for a sustained period of time.
