MGE pulsar ex10 start up it goes through test mode and comes on for about 10 seconds and then goes to bypsaa and alarm. Batts. are new. When I unplug before it goes to bypass/alarm system runs on inverter ok. I need solution or a schematic. Thanks

where did you find this old UPS> ? I'd bet cash it did not just fail 14 years online TODAY.!?
Redux1 this is way too long but there are many sub models of PULSAR and non told yet. by you.
nor if TOWER OR RACK MODEL is your? wow. that. ? not the same batteries at all in both ever.
did not read your manual first.

14 YEARS old it is, and now owned by APC.com (a 2007 event)wiki it.
The HIGH DC means the Charger output is too high
or the 36v 3 battery loop is broken (no load equals charge voltage is too high DC bus)
if you have rack UPS and use 12vdc batteries, in it (not 6vdc as it must) the DC bus will be too high.
UPS is complex and more so not telling full model numbers of it and photo of if.



the LIST OF what can be wrong, (besides bad PCB inside)
wrong batteries, used, or connected wrong.
battery terms rusty. or just loose.
EXB option was enabled before (14 years ago?) and not reconfigured now that it is gone. now.
battery breaker rear tripped. in inside batteries and if EXB option the outside battery breaker tripped. on it.
wire backwards is prevented with connector keys, but if hacked , any thing is possible wrong,.
no photos of yours, the DC bus is 36vdc on the tower. 3x12=36v


AC LINE IN CAN BE SET 100VAC TO 480VAC, (TO COVER WORLD POWER USED)
if not configured day1, correctly there is no hope, only smoke.
what AC voltage is your country, (at home are you) and freqency, 50 or 60HZ, (most are auto set for Hz)


MGE is nOT MEG. at all. sorry but typos like that make help super hard.


just one of many 1500, I can not guess what your REALLY is, Pulsar has many sub models.

MGE is now owned by APC for 14 years today, UPS company (a top maker)
and this model is not supported now it is too old,,, found in garage sail for $1 USD, I'd pass on that.

and APC does not support this very very old UPS now. they chose not to support it, but gee call them and ask.
Apc.com, click support , and contact them.

next time post photos of front and rear.
and full model number not just "Pulsar 1500," shortened like that. and MGE not MEG.
and what country you live and if at home or using commercial power , 100v or 480vac or what. LINE POWER.?
last , is , if you buy a used UPS outside of your country it will be wrong AC input line voltage. and must be cured first. by strapping or configuration settings,

I have never seen any UPS made that works in all countries, and the few that do many, must be strapped first.
how that is done is covered in every UPS MANUAL made, in the world.
if done wrong this test step, you will get smoke or worse fire. (only fuse can save you from that done wrong)
never bypass fuses OK
and if doing other hacks say so, tell the hacks , like using the wrong batteries.

This is a commun problem with this unit, you need to replace the static switch but it will cost you more than a new system, get rid of it.

send the detector back and have it replaced,
The CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the following time range when exposed to the corresponding levels of CO: 70 ppm CO Concentration 60 - 240 minutes 150 ppm CO Concentration 10 - 50 minutes 400 ppm CO Concentration 4 - 15 minutes The alarm shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. When the unit detects carbon monoxide, the alarm pattern will be four (4) short beeps - followed by five (5) seconds of silence - followed by four (4) short beeps. The unit shall incorporate 2 LED's. A green LED will be illuminated to indicate the alarm is operating properly when plugged into an outlet, and will flash every 10 seconds when on backup battery power. A red LED will flash to indicate that carbon monoxide has been detected until the device is reset or CO is eliminated or will flash to indicate low battery or alarm malfunction. The unit shall at a minimum meet the requirements of CAN/CSA 6.19-01. It shall also include a 10-year manufacturer's limited warranty or

Test/Reset Button - Tests the unit for proper operation. Resets the carbon monoxide alarm.
• Tamper Resist Feature - If activated, unit goes into constant alarm mode if it has been unplugged or has come loose from the outlet.

Red beeping triangle is a major alarm. It is most likely an internal fault. The inverter section are often the main reason. A technician has to look at the internal problem.

My mge 1500 ups is indicating fault behind with an Problem with the MGE UPS Pulsar Evolution 1500 UPS System my mge 1500 ups is indicating fault behind with an led flashing red and there is no output from the ups with or without ac input

The Galaxy 3000 can only be serviced by a technician with access through to the UPS via software to reset an aging meter. This cannot be reset by other means. Who ever replaced your batteries should have arranged this. My email address is [email protected]. If you let me know where you are located, I can maybe suggest some options for you.

Some economics UPS have a functin called "Green Function". A timer disconnect the load after 5 min to prevent damages on internal circuit.
You can confirm this:

- battery remain to good level charge
- UPS restart for other 5 min if you press On button

See manual if you can disable this features.

MGE Pulsar 3000 is an online UPS. try to check the battery first if its ok. coz for an online UPS it will need to have a good working UPS battery to trigger the switching relays to on the online UPS unlike backups UPS that can be turn on without any batteries

Buy a CB10 10 ohm ceramic resistor (10%)

Alagator clips on (+) (-) and on the resister. If the battery can not hold the charge after one minute above 12V DC, but drops very quickly that battery is due to be replaced. Very simple test and cost hardly nothing.
