 To restart a system, first switch all units off, one by one. And then switch all units on again. Do this with the On / Off / Charger-only rocker-switch on the front of the device. To restart a system, first switch all units off, one by one. And then switch all units on again.

   - This error often follows VE.Bus Error 1. Solution: solve the cause for VE.Bus Error 1. Note that when using an older CCGX (version before v1.40), ​ it can be that the first error is not reported on the Alarm log on VRM. So even when it only lists VE.Bus Error 3, it can very well be that that error was preceeded by VE.Bus Error 1.   - This error often follows VE.Bus Error 1.

-Error 17 will only appear on slaves. ​You'll see it when its phase-master ​is no longer communicating on the VE.Bus network.+Error 17 will only appear on slaves. ​They report this error when there communication with the phase-master ​has timed out.
  
-  * In some cases this error can be seen temporarily while using Remote VEConfigure to write a new configuration. +Steps to take: 
-  ​The most likely cause is bad cabling/​contacts ​on the VE.Bus: ​Check cabling and contacts. Make sure to also inspect the female RJ-45 sockets, instead of only the cabling: ​Sometimes ​badly mounted RJ45 cable connectors prevent the spring-contacts in the female RJ45 connectors on the Multis to properly make contact. +  - In some cases this error can be seen temporarily while using Remote VEConfigure to write a new configuration. \\ __Solution__:​ ignore the error; the system will recover by itself

If that doesn'​t solve it, replace all network cables, including the cable to the [[venus-os:​start|GX Device]]. Make sure to also inspect the female RJ-45 sockets, instead of only the cabling: ​sometimes ​badly mounted RJ45 cable connectors prevent the spring-contacts in the female RJ45 connectors on the Multis to properly make contact. Make sure to machine-made cabling. Do not use self-crimped cables
 +  ​DC fuse blown. ​In this case, all units can in some situations seem fine and work well as long as mains is available. And then when there is no longer AC available on the input (mains fails or generator is stopped) ​the non powered units are disconnected from the system. \\ __Solution__:​ Check the fuse in all units; replace the broken one. 
 +  - Update firmware and Assistants of the inverter/​chargers. And of the GX Device. \\ __Solution__:​ [[updating_firmware:​updating_ve.bus_products|Update the Inverter/​charger firmware]] - [[assistants:​how_to_update_an_assistant|Update the Assistants]] - [[ccgx:​firmware_updating|Update the GX Device firmware]].

 +If after all above steps you are still experiencing a VE.Bus Error 17, contact your dealer whom will contact Victron repairs; please provide photos of the installation and network cabling. Depending on the situation, they might advice to replace the [[venus-os:​start|GX device]] and the inverter/​chargers. We advise to replace only the GX device first since that is less work.

   * The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a generator. Especially when combined with AC loads that increase their current draw when the AC voltage drops: by the time that the inverter/​charger initiates the disconnect, the current through the relays has increased well beyond the ratings, and is too high to open them.\\ __Solution__:​ Make the Multis or Quattros disconnect earlier: increase lower limit of AC input voltage in VEConfigure3. For example to 210 VAC. The factory setting is 180 VAC.   * The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a generator.

-__How to determine ​which unit raised ​the error in parallel, multi or split-phase system?__+Error 24 will always appear on all units at the same time. There is unfortunately no indication, not on LEDs, nor on a GX device, VRM, or any other manner, ​to see which of the devices caused ​the error. Below procedures outlines how to manually determine which unit has faulty relay.
  
-First, always double check option 1 and 2 in above list. Those are the common causes. In case that doesn'​t lead to a solution, follow this procedure to find out which unit raises the error.+Do make sure to first, always double check option 1 and 2 in above list. Those are the common causes. In case that doesn'​t lead to a solution, follow this procedure to find out if its a relay issue, and then which unit.

Do not first reset the system; and do not reset it after making the video either.+Start with making ​a video of all units and their LED code. Do not first reset the system; and do not reset it after making the video either.
