1-Wire Network Troubleshooting

If reported item is IRD Controller inside GOC (“DIFOCHDv”) then remove jumper cable and connect cables J4 and J5 to IRDC J4, J5.

Locate input and output 1-Wire connections to item and reseat.

If reported item is SRPS then reseat or replace SRPS Control Board.

If reported item is eSRPS then replace.

If reported item is Cronus then reseat or replace GMC Board.

Replace any other single reported item.

Locate connection between PHPS and first reported item and reseat. Remove PHPS2 and SRPS power before reconnecting any cable.

If system is 32ch, can swap entire cable between RRx1 J7 and RRx2 J7 and TDM J1 and J2. Remove PHPS2 and SRPS power before reconnecting any cable.

Can bypass or remove DTX1, DTX2, Cronus, and PEM. Cannot bypass CFB.

Replace item “Not Detected” that is ‘nearest’ to PHPS on 1-Wire network and cable connecting item to network.

Remove power from PHPS. At front of PHPS, remove cables at connections J8 and J10. At magnet room side of Pen Panel, remove cables at connections J35, J41, and J42.

Restore PHPS power. Repeat 1-Wire test (TPS Reset not necessary) and confirm “PHPS BOARD ID Detected”. If OK skip to Step 9.

If not detected, then remove PHPS power. Perform system shutdown. After shutdown, install Emergency Stop bypass jumper to J103 connector at top of PGR Cabinet. Remove cable at J40 on magnet room side of Pen Panel. Restart system and start applications boot.

Repeat 1-Wire test and confirm “PHPS BOARD ID Detected”. If detected, then skip to Step 11.

Remove PHPS2 power. Remove cables at rear of PHPS from J40, J41, J42, J43, and J35. Temporarily remove filter module at PHPS J35.

Restore PHPS2 power and repeat 1-Wire test and confirm “PHPS BOARD ID Detected”.

If detected then remove power from PHPS2. Install cables one at a time until bad cable identified and replaced. Remove PHPS2 power before reconnecting any cable. Proceed to Step 14.

If not detected:

1. Confirm DIP switches on USB-to-Serial converter in rear of GOC set SW1-ON, SW2-ON, SW3-OFF, SW4-OFF.

2. Reseat USB connectors at PC and converter, sub-D connector at converter and FJ7, sub-D connector at J12 PHPS2.

3. If necessary replace converter and PHPS2.

4. Proceed to Step 14.

Remove PHPS2 power and reconnect cable at PHPS J8. Restore PHPS2 power and perform 1-Wire test. If not detected, skip to Step 12.

Remove PHPS2 power and reconnect cable at PHPS J10. Restore PHPS2 power and perform 1-Wire test. If not detected, skip to Step 13.

Remove PHPS2 power. At magnet room side of Pen Panel, reconnect cables one at a time to J35, J40 (if removed), J41, and J42 until problem returns. See Illustration 3, 4 or 5. Remove PHPS2 power before reconnecting any cable. Open connection at the other end of the cable with problem. If the problem does not change, replace cable. If problem goes away, replace component that connects to cable. Proceed to Step 14.

If problem returns when J8 is connected, remove PHPS2 power and disconnect other end at SRPS/eSRPS J6. Restore PHPS2 power. If problem remains unchanged, replace cable. If problem returns, remove SRPS power. Refer to Illustrations 3, 4 or 5 and continue removing cables, one at a time, at Pen Cabinet Panel Filter, ePDB or TDM. Repeat 1-Wire test until bad item identified. Remove SRPS power before connecting or disconnecting any component or cable. Proceed to Step 14.

If problem returns when J10 is connected, disconnect other end at CFB J18. If problem remains unchanged, replace cable. If problem is gone, refer to Illustrations 1 – 2 and keep disconnecting items (CFB, DTX1, DTX2, Cronus, PEM) and cables and repeating 1-Wire test until problem returns. Proceed to Step 14.

When finished, shutdown system, remove PHPS power, and remove E-Stop jumper from PGR J103. Reconnect any loose cables. Restore power, boot software, and perform a Goodbye scan.
