EEZ BB3 Manuals

EEZ BB3 two channel kit assembly instructions Last modified: 2021-06-12 Read me first Introduction Instructions presented in this document are related to BB3 – Two Channel (Full) kit offered through a crowdfunding campaign. The EEZ BB3 kit is not an end-user product. As such, it has not been subjected to any conformance testing, and it may not comply with some or any technical or legal requirement that are applicable to fin- ished products including, without limitation, directives regarding electromagnetic compatibility and recy- cling for instance (WEEE, FCC, CE or UL). Assembling and using the EEZ BB3 requires an under- standing of electronic circuits and basic computer programming skills. If you need assistance, please contact us using this form or join us on our Discord server (invitation) or post your problem on the EEVblog forum here. Or, feel free to open a New issue on GitHub here, but please check first to see whether a similar issue already exists). The only tool required for the kit mechanical assembly is a medium Phillips head screwdriver. Of course, a multimeter for checking the wiring and voltage at a few points during assembly is recom- mended. Before you start We made our best effort to make your EEZ BB3 kit complete and functional. However, please note that due to limited resources, the kit is not completely and thoroughly tested. Basic tests were performed on the core and power modules and the cooling fan. Modules are tested on our “testbed”, but not using a wire harness, with the AC/DC modules that come with your kit. Therefore, it’s highly recommended that you check visually, mechanically and with an ohmmeter that cables are properly assembled before you proceed with final assembly (consult the Wire harness section). The basic testing covered communication over Ethernet, fan control, power control, touchscreen func- tionality, beeper, TFT display and output voltage and current programming over the full range (i.e. up to 40 V and 5 A with connected load). The AC/DC modules are capable of working with both 115 and 230 VAC. Kit version identification Starting in April 2021, the BB3 kit with new versions of the modules is on sale. They are most easily recognized by the blue color of the PCBs (Fig. 3) as opposed to the crowdfunding version which has green PCBs. The kit version with the new modules for simplicity will be listed below according to the MCU module version number which is r3B3 (the previous version is r2B4). If you own the r3B3 version, consider the following: • The SDcard comes already mounted on the MCU module. It is recommended that you remove the SDcard before mounting the front panel (Fig. 12, 13, 14). • The holes on the front panel for the Standby LED and PE terminal can be too tight, which can make it difficult to mount the front panel because the LED indicator can move in the process from the center. If this happens carefully from the back of the front panel with a screwdriver return the LED indicator to sit in its hole. • Your MCU module may have come with v1.6 firmware installed. If this is the case you will need to update it to v1.6.1 or later otherwise working with power modules (DCP and DCM) will not be possible (see resolved issue #172). • The AUX-PS module (r3B5) is missing one mounting hole (above the AC inlet). Therefore for PE connection to the chassis a separate wire is used (Item R, Fig. 5) • Top cover (Item 1, Fig. 1) has two additional holes for better fixation to the front and back panel. 1 EEZ BB3 two channel kit assembly instructions Field report update (r2B4 version) A large number of backers have already successfully completed their EEZ BB3 kit. In a small number of cases, they encountered issues with the supplied parts. The issues seen are: • The 16-pin IDC cable may be faulty (Item F, Fig. 4). The cable problem can be detected by visual inspection, and if it is connected between the AUX-PS and the MCU module, the MCU module will not work (nothing will appear on the display, no tone will be heard). If you don't want to wait for replacement use D89116-0031HK-3365/16-D-3 available on Digi-key. • Missing M3 threads on 2 of the 4 holes on the Mean Well AC/DC converter mounting frame (Item 5, Fig. 1) • One Hexagonal M3×6 mm metal spacers (Item J, Fig. 4) may be missing • One or more M3×5 mm countersunk screws (Item M, Fig. 4) may be missing • You can find excess M3×4 mm screws (Item L, Fig. 4) • TFT display on enclosure front panel (Item 3, Fig. 1) came with broken glass • Important discovery that may affect backers that has AUX-PS module r3B3 (green PCB): #108. Feel free to contact us if you notice any defect that we can arrange a replacement.
