Phason PBx-11 OMNI Select Power Block Installation Guide

Phason PBx-11 OMNI Select Power Block

Start at the Communication Center

The Communication Center provides an overview of the status of your system .

• A This button displays a window that lists system, site, and software information.
• B This area lists your devices and their status. To see a list of messages for a specific device, click the device.
  • A green “ ” on a device icon means there are no new problems with the device.
  • A yellow “!” means there are non-critical warnings or messages.
  • A red “×” means there are alarm conditions and messages that need your immediate attention.
• C This button opens a window that displays messages for all devices.

Review the devices that have alarm conditions
Click each device that has a red × and then determine the types of alarms or problems. If there are several devices with a red ×, click View all messages to display them in one list.

• If there is an “alarm cleared” message, the alarm no longer exists. Click Acknowledge to clear the messages and reset the alarm indicator.
• For all modules except Select Water and Select Environments, if there is not an “alarm cleared” message, the alarm still exists. (Select Water and Select Environments do not have “alarm cleared” messages.)
• For fault alarms—alarms caused by an out-of-range condition—check what is causing the alarm; for example, a jammed sorter, power failure, high temperature, or other condition. Fix the problem that is causing the condition and acknowledge the alarm message.
• For communication alarms, continue reading the next section. If the devices are connected wirelessly, also read Troubleshooting Wireless Adapters (PWAs).
• For all other problems, read Error! Reference source not found.

Create a site map

Before you start troubleshooting communications, you need to know the sequence of devices on the communication cable. If you do not have this information, follow the steps below to create a site map.

1. Create a Site Structure Report.
   • a) Log in to OMNI Select.
   • b) In the main window, click Reports, and then Site.
   • c) Below Reports, select Site structure, and then click Create report.
   • d) In the report, find the Buildings and devices section. Each device has information similar to the following example. The important information to note is the device name, type, and address.
2. Enter the information in the site map template at the end of this troubleshooting guide. Determine the order of devices by following the cable between devices.

Important troubleshooting information

• When replacing a circuit board, use new replacement boards. Using a circuit board that has been sitting on a shelf without an anti-static bag can cause more problems.
• Because electrical interference from AC power cables can cause communication problems, make sure communication cable does not run beside or in the same conduit as AC power cables.
• Because poor grounds or different ground planes between buildings can cause communication problems, use a spare wire in the communication cable as a common reference connection (at position E) between each device. For more information, read the RS485 installation guide, available at www.phason.ca.

Troubleshooting communication problems

Use ToolKit to get a current status of communication
Because multiple communication alarms can occur over time, start by using ToolKit to determine the current state of communications. Read the Using ToolKit section for details.

Determine the type of communication problem
Communication alarms will be one of two categories. Use the section that applies to you.

• Communication alarms for ALL devices in the system
• Communication alarms for SOME devices in the system

Communication alarms for ALL devices in the system
The problem is between the computer and the PCH (or RS485 Converter if you are not using a PCH). After each of the steps below, use ToolKit to test communications.

1. On the RS485 Converter, make sure the power light is on. If the light is not on, it could mean the USB or power cable is unplugged. It could also mean the software drivers are not installed properly. Refer to the RS485-FD installation guide for driver installation.
2. Repair any loose or broken wires on the RS485 Converter.
3. Perform loopback tests on the following devices to determine which one is causing the problem, and then replace the problem device. For more information, read Performing a loopback test.
   • a) Serial port (only used with RS485A)
   • b) USB-to-serial converter (only used with RS485A)
   • c) RS485A or RS485-FD converter
4. If you are using a PCH (Phason Communication Hub)
   • a) Make sure the incoming voltage is 12 VDC.
   • b) Perform a loopback test at the end of the cable that is plugged into the To PC port.
   • c) Perform a loopback test at each used output channel.
5. If devices are still not communicating, proceed to
6. Communication alarms for SOME devices in the system.

Communication alarms for SOME devices in the system
Test the PCH channels
If all devices on one PCH channel are not communicating:

1. Re-strip the wires and test with ToolKit.
2. Move the connector to another channel and test with ToolKit.
   • If communication works on the new channel, the old channel is damaged. If you need all four channels, replace the PCH board.
   • If communication does not work on the new channel, proceed to the next section

Troubleshooting devices after the PCH and RS485
As you troubleshoot the devices, make sure to do the following:

• Make sure the device has power and the incoming voltage is correct (12 VDC or 120/230 VAC, depending on device).
• Remove termination resistors from any device that is NOT at the end of the communication cable. See the device’s installation guide for termination resistor location.
• Communication wires can become cracked under the wire insulation near the green connector. Re-strip the wires, even if they do not look broken.
• Make sure the color sequence is the same at each device.
• Use ToolKit after each step to test communications.

1. Re-strip the communication wires at the first non-communicating device after the RS485 Converter or PCH, and at the previous device.
2. Unplug the communication cable connector at the failed device and then perform a loopback test on the cable. For more information read Performing a loopback test on .
   • If the loopback test fails, there is a problem with the cable between the failed and previous devices. Fix the problem and retest.
   • If the loopback test passes, you have continuity to that point on the cable. The device may be faulty OR another device is faulty and causing this one to fail.
3. Unplug the cable from the device and check communications with ToolKit.
   • If communication works to the remaining devices, replace the communication board of the faulty device. See Replacing communication boards below for what to replace on the different devices.
   • If communication fails to one or more remaining devices, leave the device unplugged. You will come back to this device since other others could be causing this one to fail.
4. Repeat troubleshooting steps 1 to 3 on the next failed device, until you find the device that is causing the problem.
5. Plug in and then test communications one at a time on any devices that were previously left unplugged.

Replacing communication boards

• For PB-2 Power Blocks, replace the micro board with a K329013 PBx-11 display and K329015 PBx-11 display adapter.
• For PB-1,3,4,5,6 Power Blocks contact your dealer for replacement options.
• For PBx-10 and PBx-11 Power Blocks, replace the display.
• For PS-1 Scale Heads, replace the display.
• For all other devices, replace the circuit board.

Complete communication overhaul

When there are multiple problems with a system, it is often best to do a complete communication overhaul.

Steps for a communication overhaul

1. Check input power at each device.
2. Re-strip communication wires at each device.
3. Confirm that the E connection is wired on all communication connectors. This is the 5th wire from the communication cable that provides stability to communications. If not installed, refer to the RS485-FD installation guide for details. For devices that only have a 4-position connector, contact Phason Support.
4. Disconnect the communication cable at each device.
5. Perform loopback tests from end of cable and fix any broken wires.
6. Plug in last device (to provide termination) and test communication with ToolKit.
7. Plug in the devices one-at-a-time, and test with ToolKit after each one. Leave working devices plugged in as you move to the next device.
8. Replace the communication board of any device that causes communication loss when plugged in.

Replacing communication boards

• For PB-2 Power Blocks, replace the microboard with a K329013 PBx-11 display and K329015 PBx-11 display adapter. You must be running the OMNI Select software.
• For PB-1,3,4,5,6 Power Blocks contact your dealer for replacement options.
• For PBx-10 and PBx-11 Power Blocks, replace the display.
• For PS-1 Scale Heads, replace the display.
• For all other devices, replace the circuit board.

Using ToolKit

ToolKit is a communication and troubleshooting tool included with OMNI Select. Use ToolKit to confirm devices are communicating and help track down where communication problems are occurring.

How to check for devices

1. Log in to OMNI Select. Default username is sysadmin and the password is omniadmin.

2. In the Site tab of the Settings section, click Start ToolKit.

3. In the Devices tab, click Check for All Devices.
   The current time will appear in the Response Pending column.

   • If a device is communicating, a time will appear in the Last Response column.
   • If no time appears, the device is not communicating

ToolKit details

Multi-point PWAs tab
This section is for systems that use the PWA multipoint wireless adapters :

• Find Multi-point ECM PWA – This button searches and then displays the address of the PWA-ECM wireless adapter connected to the system.
• Find Multi-point ES PWA(s) – This button searches and then displays the addresses of all PWA-ES wireless adapters within range to respond.
• Add PWAs to OMNI Select – This button adds all discovered PWA-ES addresses to OMNI Select. You can also add the addresses manually in the Configuration > Site > Wireless Adapters window of OMNI Select.
• PWA setup – This button allows you to set up PWAs. This is not required for troubleshooting; it is required only if there is another OMNI Select system with PWAs within range, and it is interfering with communication. Refer to the PWA-MULTI installation guide at http://www.phason.ca/pdfs/pwa-multi_250446.pdf for details.

Performing a loopback test

A loopback test verifies the continuity of the communication cable. During the test, the computer sends information on the communication cable. The information “bounces back” when it gets to the loopback connector. The computer then compares the information it received to the information it sent; if the information is the same, the test passes. When a loopback test passes, it means both the send (TX) and receive (RX) lines are intact.

Loopback connectors
To perform a loopback test, you need loopback connectors to connect to the cable or device. A loopback connector package (PKG-LOOPBACK) is available from your dealer or Phason and includes connectors for different locations/connector types on the communication cable. If a loopback connector is not available, you can create a temporary loopback for most situations by inserting wires into the connectors as shown to the right. However, this type of loopback connector will not work for a serial port or USB-to-serial port loopback test.

Perform a loopback check with ToolKit

1. Connect the appropriate loopback connector to the test location.

2. In ToolKit, click the Serial Port/Loopback tab.

3. Click Loopback test.
   The Loopback test window will open.

4. Click Run Loopback check.
   This performs a loopback test and displays one of the following responses below the button.

   • No Loopback detected – this means there is a break in the cable; a damaged serial port, RS485 Converter, or USB-serial converter; or a PWA radio issue.
   • Detected: Hardwired loopback – this means the cable is intact up to the loopback connector.
   • Detected: Loopback on PWA-ES address: <##ADDRESS ##> – this means the cable is intact between the computer and the PWA-ECM, and from the PWA-ES up to the loopback connector.

Perform a cable integrity test with ToolKit

1. Connect the appropriate loopback connector to the test location.

2. In ToolKit, click the Serial Port/Loopback tab.

3. Click Loopback test.
   The Loopback test window will open.

4. Click Start Test.
   This performs a continuous integrity test on the cable. The higher the green bar is on the left, the better the integrity of the communication cable. Loose and corroded connections will cause poor test results.

Troubleshooting Power Blocks

PROBLEM: PB-1 to PB-6 WORKING OK light is not on solid

1. Measure and make sure the incoming voltage (120 VAC or 230 VAC) matches the selection switch on the circuit board.
2. Switch off the power to the Power Block. Remove and then re-insert the micro board into the socket. When finished, restore power to the Power Block.
3. Replace the micro board with a new one.
4. Replace the bottom circuit board. If the Power Block functions properly, retest the original micro board to see if it functions.

PROBLEM: PB-1 to PB-6 output (fan, heater, and so on) is not operating

1. Test the Power Block using the Power Block test card to determine if the relay or variable stage works. Insert the test card in the slot below the micro board. Each press of the white button will turn on an output and its corresponding light on the display. If a load doesn’t turn on there is a problem with the output, wiring or load.
2. If the test passes, the hardware is fine. Review the settings in the software and make sure they are set to operate the load at the current temperature.
3. Use ToolKit to test communication to the Power Block. The settings in the software cannot be sent if there are communication problems to the Power Block.

PROBLEM: PBx-10 and PBx-11 output (fan, heater, and so on) is not operating
Use manual override to determine if the relay or variable stages work.

• If the test passes, the hardware is fine. Review the settings in the software and make sure they are set to operate the load at the current temperature.
• Use ToolKit to test communication to the Power Block. The settings in the software cannot be sent if there are communication problems to the Power Block.

To use manual override

1. Press and hold Unlock for three seconds until the control beeps and the unlock indicator is lit.

2. Press MANUAL OVERRIDE.
   The display shows the output percentage for variable 1. The MANUAL OVERRIDE indicator is lit and the VAR 1 AC indicator flashes.

3. Adjust the output of the various stages or states of the relays. To move through the stages, press MANUAL OVERRIDE.

4. When finished, press Lock to return to the main display. The control returns to normal operation.

Troubleshooting Wireless Adapters (PWAs)

PWA indicator light descriptions

• Radio: The light is on when the wireless transmitter (radio) is on.
• Joined: For ES models, the light flashes continuously when the radio is connected to a wireless
• network. For ECM models, the lights flash continuously at all times.
• Transmit: The light flashes when data is sent.
• Receive: The light flashes when data is received.
• Power: The light is on when the PWA has power.
• Signal: This light flashes when data is sent or received.

When operating properly and connected to a wireless network, the Power and Radio lights are on and the Joined light flashes.

PROBLEM: The RADIO or POWER lights are off

1. Make sure the PWA has sufficient power (9 to 14 VDC).
2. If the PWA is still not functioning, replace it because it is damaged

PROBLEM: The JOINED light is off

1. Make sure the PWAs are not too far apart or the signal is not being blocked by obstacles like buildings or trees. The typical range through objects is 300 feet (91 meters); line of sight range is 1 mile (1.6 kilometers). Test for an out-of-range condition by bringing the remote PWA closer to the coordinator and then testing to see if it joins. If it does join, find a better location for the PWA. Add another PWA-ES in between to improve the signal.
2. Make sure the other PWA has sufficient power (9 to 14 VDC).

PROBLEM: The RECEIVE or TRANSMIT lights are not flashing when searching with ToolKit

1. Cut and then re-stripe the wiring at the PWA and previous device.
2. Perform a loopback test at the PWA to test the cable back to the computer. Fix any cable problems.
