Color Control GX hanging, freezing

We are experiencing an intermittent case of a Color Control GX hanging, or freezing. The normal symptoms are the display looks live with an indication of AC input and battery charging etc. But in reality it has hung and showing a state that it was in when it hung.

So the first question is this common and can it be cured?

The firmware is latest and its connected to four BV700s, a Quattro and Ethernet. It is using MODBUS to communicate with PLC electrical variables and MODBUS via PLC HMI controls max AC input, i.e. 16A, 32A and 63A shore power.

There is a degree of worry that there might be an issue where the Quattro in conjunction with CCGX may be creating the hanging and thus reluctant to treat this as a pure CCGX issue. The reason for this is there have been some issues where Quattro has not always being doing exactly as expected and have experienced issues where after a hanging we can only get everything looking right after a number of resets of both Quattro and CCGX.

One of the most odd indications of something is not right is the MODBUS command to switch between 16A and 63A works fine and the CCGX shows the correct value on change. Thus that looks good. But when in VRM the Input Current Limit is showing 32A. Also I cannot connect to CCGX in Remote Console on Desk PC, Laptop or iPhone App, irrespective of what network I'm on. So something is not right.

Any thoughts welcome. Thank You

Simon

Hi @Simon Churchill

Just a suspicion, you may be overloading it. The CCGX is one of the lesser powered GX units, and I believe hanging is one of the symptoms. Some explanation in this comparison (see Note 1).. https://www.victronenergy.com/live/venus-os:start

We only have 4 VE Direct devices where max is claimed to be 5. So would like to think not.

This may be the case. But I have been asked to switch the CCGX out for other and see what happens, and send current unit back to supplier for inspection. I'm hesitant to order a new unit and charge client for new if the problem just returns. We have a sister vessel with same set up and they had similar issues, but I was not involved in the issue at that time due to vessel location. It got swapped out for new and as far as I'm aware problem has gone.

I have been made aware of a possible issue that led to a series of CCGX being replaced on warranty and both vessels units would have been ordered by us at the same time, so it may be the case that this one is suffering the same. Both CCGX units were ordered back in March 2018 so will not be under warranty and the problem has generally be ignored and a simple power cycle has been applied each time, by the crew.

The reason for posting this issue here is to get some feedback from others who might be familiar with this issue and have an opinion that will make it easier to justify the replacement and risk that problem does not go away. Hence the question about possible cases where VE Bus devices might have an influence on each other and cause a crash or freezing of each other.

Thus what I'm hoping for is someone who is familier with this issue to give a little support.

Thank you again

@Simon Churchill

If you were to switch it out, consider replacing it with a Cerbo GX. This has the option of a Touch50 (or 70) screen, No buttons (a touchscreen), and even an optional bezel to make it fit the CCGX panel cutout. Much more power and connection options. In it's heyday the CCGX was great. Cerbo now the flagship, and such an upgrade might help the client see where the cost has been applied.

My money's still on the overload thing. Should fix that admirably.

I had thought about Cerbo. We have used before, but was not available when we specified these boats. The trouble is justification. I could suggest to the client that it maybe a good idea, but as I said earlier the other vessel is the same and not having this issue.

I appreciate the justification thing. And I wish someone else would raise other possibilities, as 'overloading' is hard to quantify as the culprit.

Firmware up to date? Not just the CCGX (v2.92 the latest), but the other kit too. That vintage CCGX dates to about the time the earlier ones couldn't handle the later added remote (VRM) Quattro fw update feature (#1342 message). Something to add to the justification list if applicable.
