iNS2/iDS2 2-Wire System Troubleshooting
Flash Patterns of Button's LED |
Meaning |
| 2 | Button Searching for iCCU |
| 3 | Button Performing POST (Power On Self Test), or Button In Maintenance Mode |
| 4 | Button Phase Unassigned, or SDLC Error, or Button's Assigned Phase not receiving valid interval data (according to the iCCU) |
| Rapid | Sudden loss of iCCU Communication (reboot power supply or button) |
| 5 | POST (Power On Self Test) Fail |
| 2 quick blinks (3x) | Flash LED Initiated/BLE Connection established |
| Constant Call |
| Check flash patterns, if rapidly flashing, move to communications loss troubleshooting steps |
| Check phase assignments in field service app, if extra buttons are present on this page, unassign them |
| Check the field service app to see if the buttons are receiving interval information. If not, check wiring on load switches (for 4 Channel mode or SDLC mode) or SDLC BIU assignments (for BIU mode) |
| Make sure cabinet controller is not set to Recall for that phase |
| Remove PLC wires from buttons. If the call goes away, the issue may be with the buttons or field wiring. |
| Connect button directly to the PLC port on the iCCU-S/S2 or the ICB to bypass field wiring. If the issue follows, swap the button with a known good one. |
| If SDLC Hybrid mode, check if iCCU is receiving SDLC data. |
| Button will not place call |
| Check button flash patterns (see above) |
| If flashing twice, change communications channel under Advanced Communications Settings in the Field Service App. Factory default is Channel B. Change from B to A and give the system up to 5 minutes to find everything. Change to Channel C, if still flashing twice on Channel A. |
| If flashing four times, check Phase assignment using the Field Service App. If button is correctly assigned a phase, check Interval Status (iCCU Configuration > Cabinet Ped Interface > View Interval Status) |
| Confirm Cabinet Ped Interface is configured correctly in Field Service App under iCCU Configuration (See Quick Start Guide) |
| See if Locate tone and wait messages are audible. If not, measure voltage across field wiring to see if 24VDC is reaching the PBS. |
| Will not power on |
| See if other buttons are powered on. Check for 12-14 gauge wire and ICB wiring. |
| Measure voltage across button wires for 24VDC. If not present, measure across PLC terminals on iCCU for 24VDC. |
| Will not exit maintenance mode (3-Flash) |
| Ensure maintenance mode is not enabled under PBS configuration, Settings. |
| Power cycle the button, if still in 3-flash, RMA the PBS |
| Will not play audio or distorted audio (Custom Messages only) |
| Ensure Walk Mode Sound is set to "Custom Walk 1" and Information Message is set to "Custom (With Pulse)" using field service app, under PBS configuration, Settings |
| Make sure audio file is in *.ogg format. If not, convert the audio file to *.ogg format using the PC Intelligent Config App. |
| If audio is still distorted or will not upload, it may be corrupt. Either request a new audio file from Polara/distributor, or create a new file using an audio recording application such as Audacity (Mono, 48000Hz, 32-bit float). |
| Will not play audio or distorted audio (All sounds) |
| Ensure firmware is the current version. This can be checked and updated using the PC Intelligent Config App or the mobile field service app under Firmware Update. |
| Power cycle the button by disconnecting, then reconnecting one of the button wires. |
| Measure resistance across the speaker terminals (cannot be field tested for iN3). If significantly less or greater than 8 ohms, send in the PBS for RMA. |
| Low Audio (All sounds) |
| Verify "Quiet Time" is disabled |
| Intermittent communications loss with iCCU |
If flashing twice, change communications channel from B to A under advanced communications settings in the field service app. Change to Channel C, if still flashing twice on Channel A. iCCU-C/C2 systems: power cycle power supply brick after each channel change. |
| Ensure use of 12-14 gauge button wire. |
| Ensure use of dedicated pairs of wires from each button to the interconnect board. |
Check wire continuity. (Resistance: 1.5 Ohms or less for total run (from cabinet to pole and back to cabinet) To check, disconnect field wires on both ends; twist the 2 wires on one end & measure resistance of the entire run on the other end.) |
| Cannot connect to button via Bluetooth |
| Make sure field service application version is up to date. |
| Android: cycle the Android device's Bluetooth off and on, then try again. |
| Ensure that the Bluetooth setting on the iCCU is enabled (front screen menu iN2 Bluetooth Enable/Disable). |
| iN2 Only: Check if wireless sync is enabled, hold the button for an extended push, then see if device shows up on the Connect menu of the Fiels Service App (connect to it before the device cycles back to DW). |
