Does anyone know WHERE and WHEN the cert battery warning is visible on a (classic) Barco ICMP GUI? I know I need to replace the battery soon, but I still would like to know where the warning would show up.

Good question!
The relevant InfoT (1381) says a "a timely warning will be generated on an active ICMP installed in the projector when replacement is due" but doesn't say how or where.
I haven't seen a warning. Maybe someone else has? -
Yes. From memory, you'll get a yellow tail light, and if you click on the warning triangle bottom right in Communicator, you'll see an "ICMP battery is almost flat" entry. Don't have a screenshot - sorry. You might also have to be on a relatively recent version of the projector and ICMP software/firmware bundles, and version of Communicator, for this to work. I've experienced it twice, and in both cases the old battery I pulled out read 2.9something.Comment

Main problem with it is that if voltage of battery rises a bit warning is moved!
I've had few cases where battery was low and warning was there, but operator saw it way later. For example, in sp2k without tail light, operater starts the projector some hour before show, he do something else while projector boots etc. When projector boots there is warning, but after booting projector gets warmer and battery voltage rises few mV and warning is cleared automaticly....and when operater logs to projector around 15 min after booting everything is ok. Some month after, when battery is way too low alarm stays abd operater calls you. Than in logs i can see first warning was about 3 to 4 months earlier!!
First, they should implement that such of warning that js not cleared by itself, but with operator confirmation, so you need to click that you saw it before is cleared, even if voltage is again above treshold (I think 2.8V).
Barco always tells you that in year period service, you should check logs for battery alarms....
Plus replacement procedure is way too tricky.....I have heard situation from official barco training that they show how to replace it and icmp was dead after......
They could just put two dio switches, where you can have emplty socket disconected while installing new battery, and they switch it on, switch off old one and just take old one out without any problem....Comment

As long as the battery has not drained to the point of being right on the cusp, as long as you remember to put a plastic drinking straw over the spring-loaded positive terminal while pulling or inserting a battery, and as long as you use regular CR2477s, not the N variant (on the N variant, it is easier to short the positive and negative with your finger), you should be OK. I've lost significantly more SX-3000s than ICMPs and ICP-Ds while swapping batteries.Comment

Thanx all!
Leo - why don't you like the 2477N? I noticed it is much easier to insert it into the socket because of the narrower bottom.Comment

I'm with Leo...I don't like the "N." The battery just feels loose in the socket. For servers (or ICP-D) with batteries, I'm trying to change them a year early. I'd rather the system not be teetering on the cusp of failure. Batteries are cheap...failed servers are not.
Thus far, I have yet to lose a GDC server on a battery change (SX2001, SX-2000AR, SX-3000, SR-1000). I'm also still clean on the ICMP battery swaps. This year, I start on the ICP-D battery swaps.
In the way-back news...I was working on a Panastereo recently and also make a point of changing the 3.6V battery on the Control board...once it goes flat, it will start to leak and then start etching the board, like a capacitor...I go to change it out and my new battery (still in its sleeve as I still deal with enough to buy them that way)...was down to 1.6V! Fortunately, the one on the board was still measuring good. If any of you still do have Panastereos and don't power them up often, I do recommend just pulling the battery. They don't go bad when they're powered up...just when they're powered down and draining on the battery.Comment

Marin is right. Once the low voltage warning comes up it should stay there until a new battery is put in place. The threshold point is at 2,8 Volts. I hope that Barco will fix this in future software releases.Comment

I've had one trivial situation last winter. Operator called me that he saw low battery alarm on sunday and that he even take out logs from projector. Since they run only on weekend, when he powered projector on next saturday, icmp did not boot as batert was dead......well yes he did forgot to call, text or email on sunday..... So i went there with spare server and i just check out that logs, well alarm was there more than few times a three moth earlier... Since SPxK doesn't have tail light and this one either have lcd, he did not saw it....Originally posted by Christos Gartaganis View Post
As for barco, i think i spoke with more than few people in support, training and so, they just like don't have anz answer why that alarm is treated so "easy".....Comment

Similar here for 2 Barcos used in summer locations on camping grounds. They were put into storage before the winter, not looked at, and when it became spring, the batteries were depleted on one and gave a warning on the other.
The person in charge tried to swap on the one with warning, but used a screwdriver and shorted the cell contact.
So both ICMP had to be returned for the factory service for replacement. You can't just connect anything else with ICMP...
Costly reminder to take a little bit care for your equipment.
You might even tell clients to keep the power on until replacement to prevent full drainage, they still turn off to save electric bills of a few cents. And pay some grands afterwards to get service restored.Comment

There is another thing comming up (maybe)......in case one see alarm and leave projector turned on......everything is ok,. But, this come up to question. Does the certificate FIPS IC is powered from power supply while ICMP (projector) is on, or does certificate FIPS IC is powered only via battery? If FIPS IC is powered via battery ONLY than laving projector on will not make difference, much, as it will not boot when next time FIPS will not be read from ic.Originally posted by Stefan Scholz View PostComment

Because it's easier to short it accidentally with your finger. On the N, the surface of the negative terminal extends up the side of the battery as far as the orange insulating ring just under the rim of the positive. Therefore, if your finger touches the side of the battery at all, you can cause a short. If you do that while removing or inserting the battery, the risk of shorting the actual circuit and thus losing the certificate increases, for example, if the drinking straw you've placed over the positive terminal of the holder starts to move with the battery, and you accidentally have one finger on the side of the battery, and another touches the terminal on the holder.Originally posted by Carsten Kurz
On the regular CR2477, the surface of the positive terminal extends all the way down the side of the battery: only the bottom surface is the negative. The risk of making an accidental short circuit while manipulating the battery in or out of the holder is thus a lot lower.Comment

Why couldn't you wear a pair of nitrile rubber gloves? Nitrile is a good electrical insulator.
At the place where I work, parts have to be hipot tested with 600v AC. If the operator touches a part while under test, they can get a nasty shock. Even though the current is only a few milliamps, it still hurts like hell. You don't have to ask me how I know.
The solution is to be sure you don't touch the part while it is under test but there are still times when an operator either bumps the part, accidentally, or, sometimes, they'll grab the part, thinking that the test is finished but the part still might be energized for a moment. Both of those things have happened to me. If you're careful, there's no problem but, if you want to be extra careful, you can put on a pair of gloves and you'll be 90% safe from those little accidents.
If gloves can protect you from a 600v hipot test, they'll certainly protect a five volt watch battery from shorting. Further, the salt and oil from fingerprints can reduce the life of a button battery if that fingerprint bridges the positive and negative sides of the battery. Wearing gloves would guard against that, too.
Unless there's something I don't understand, I don't see any reason not to wear nitrile gloves when changing batteries in a projector.Comment
