  • My ENC do not turn on after software update

ENC buttons operating principle may seem strange for beginners. These are custom designed piezoelectric modules integrated into thick polycarbonate front-panel. Rubber “buttons” have indicative function only (easier operation in thick gloves- diver knows where the piezo modules are located).

Designing a non-magnetic solution that guarantees operation in very wide range of extreme pressures- up to 300m depth- is not easy task, with ensuring reliability and simplicity. Some “geting used to” their operation is recommended, as ENC operation may be different from any other device you have used previously.

When diving, water pressure around this device is changing slowly all the time. Buttons cannot be sensitive for SLOW pressing/depressing. If so – only RAPID pressing can activate buttons. Thus, to activate button, quick “tapping” action rather than “pressing” is favored.

In the upper part of the device (nr 3 on the picture below) there is small red LED. It will light up when a button is pressed. It allows for clear evaluation about the buttons operation- if the LED is lighting when button is pressed, it works.

If you cannot turn ON the device and both buttons are working- device may be discharged, or they are not pressed simulatnously.

In our ENC devices, the present baterry charge is not measured precisely, but approximated by present battery voltage. This is common behavior in many products, hoever it has some limitations. Our battery is very specific- low-magnetic construction, thus implementing a more precise remaining charge measurement method is not possible.

 

We are using almost maximum allowed charging current to make charging time as short as possible. This is hardware-coded and cannot be changed programmatically.
During charging, the internal battery is slightly heating up – and it’s voltage increases more than it’s “real” value (from collected charge). When you disconnect the charger and wait few minutes, the battery goes back to his normal temperature and voltage MAY drop, so displays drops too from 95% to 87% at once (for example). Even in your cellphone this effect is present but hidden with sophisticated software “tricks”, which we don’t want to follow.

If you want to make sure your ENC has maximum charge – leave it connected to the charger for 2,5 – 3 hours one time. There is no possibility to overcharge – inside we have 2 independent hardware protections. This is recommended especially when your ENC was unused for long period (>2 months).

Many factors have an influence on ENC work time. We designed our console to work at least 20 hours (brand new battery) in typical usage. So if your device was fully charged (see above) and cannot work for at least 10 hours (recording on, underwater, in water temp. >= 10 deg. C) there is a possibility that battery or device itself has some issues.

Please remember also about one important thing. It is really hard to find good 5V charger. Some of the “charging problems” may be caused by them, not by ENC battery or electronics. If we have some suspicious if the charger is good or not, we usually try charging by PC USB port and observing if it is going better / quicker / … But there is also no common rule for that – modern PC (especially laptops) has some strange “protections” and they may assume that ENC is trying to get too much power from them. You will have to try yourself.

Other useful tips  :

  • battery performance may be degraded due long storage, but it is reversable after first long charging procedure.
  • battery charge indicator may drop with temperature , especially in 0-10 deg. C range .
  • battery capacity may drop to it’s half after 300 full charging-discharging cycles, or after 1 year from the manufacturing date – this is natural, altough many manufacturers tries to hide this information from the users. ENC battery can be easily replaced by the Seacraft service.
  • battery voltage measuring has 3% accuracy (sometimes better, but no worse), so it may happen that really fully charged battery will show “only” 95 or 97% and this is also normal
  • it MAY happen, that if ENC was left in the sun and heated up to 40 deg. C or more, you may not be able to charge it until it is cool down (internal protectors)

If you proceeded carefully the procedure described in your ENC manual and there is still a problem with Bluetooth connection, you may try:

  1. Try to disable WiFi in your PC/Android device (switch-off), just for time when you updating firmware in ENC. WiFi has similar operating frequency (2.4 GHz) and it can interfere with Bluetooth.
  2. Try to place your PC/Android device and ENC just like on the picture below. Due to the alluminium housing and BT module location- it proven to be the best data transfer position. Send to our support the model and Android version of your mobile device, if you can.
  3. During the update process, try to observe Seacraft application on your Android device. There will be small green counter saying ‘Processing xxx of 2048‘, almost on the center of the screen. Value xxx should increase from 1 to 2048 (for example). If it hangs – something is wrong with data transmission (please inform us about it).
  4. At last you may try other option, but only if everything else failed.
    Put your Android device away. Run ‘Send data’ function on your ENC. Then press quickly top button on ENC, 5 times or more.
    The screen will go off and red LED diode on ENC will blink several times, then ENC will go to the main screen. In newer devices (2019 or 2020 models) you will see the message „Wait” in the center of the screen during this process. This (hidden) procedure is for resetting the transmitter inside the ENC. You may need to run this procedure 2 times, if the first time didn’t help.

 

If your ENC device cannot get the GPS location, try to :

  • switch off the „Auto-OFF” option in the configuration (see manual how to do this)
  • make sure the ENC is charged at least 50%
  • go to the open area (away from high buildings, trees, metal bridges, …)
  • switch on the ENC and leave it alone, screen towards the sky, for the 5 minutes
  • If after 5 minutes there is still no GPS indication on the ENC (green or yellow colour of GPS icon), the internal GPS receiver may be broken. Contact our support for determining next steps.

 

CAUTION – when the weather is bad (low, dark clouds cover the sky), you may need to wait even 10 minutes for the first fix.

After successful GPS fix, another fix’es will be easier/quicker for at least 3 days, unless you move to another region of the world. This is an internal GPS feature.

When you cannot switch on your ENC:

Please push first the lower button and then the upper button few times. Look at the small circle on the top of the ENC, above the screen. There is small red led light deep inside. This light should blink each time you press any button (in off state). That means buttons are OK and device has good condition (battery has some voltage and electronic inside is working correctly).

Of course if you push both buttons at the same time, the ENC should power-on.

If one of the buttons is causing blinking and the other is not – it means one of the piezo buttons, or connectors failure.

If no light can be seen when you pushing any button – propably battery is discharged below the limit. Both button failure never happend.

 

Battery has it’s own, independent discharge protection. And ENC is drawing very small current even when it is switched off – the internal clock must be running, also water immersion sensor (auto-on function), atmospheric pressure detector and some more features are periodically called. When you leave ENC console switched off for long period (i.e. 3 months or more), it may happend that battery is totally drained and you will have to charge it again.

Other advice – make sure the ENC is off and left alone for at least 5 minutes. Connect the charging cable to the ENC (with other end left unconnected). Then connect the other end of the cable to the charger or PC USB port. Wait 10 minutes even if the screen is still blank. The ENC console should turn on at least for a while. Do not disconnect it from the power source for at least 20 minutes. If the battery was drained, the device may not power on immediately (battery diagnostic test inside delays it). Also, when it switch on, it may blink, restart few times. This is natural after long lasting in full discharge.

 

When device is not switching on even when charging, it may be  flooded.

You can leave the ENC in cold place, turned screen down, for 2-3 hours. Then watch the screen and the front cover (transparent part of it) – if you will see any “fog” or water drops – it was flooded and it will not switch on.

CAUTION – when device screen is blinking or device is restarting for long than 15 minutes – it is propably broken battery. Contact our service for additional help.

ENC should be washed with fresh water, and dried.

There are no obstacles to store your device for prolonged time- however, you should be careful about too-deep battery discharge.

 

ENC’s battery has it’s own, independent discharge protection. And ENC is drawing very small current even when it is switched off – the internal clock must be running, also water immersion sensor (auto-on function), atmospheric pressure detector and some more features are periodically called. When you leave ENC console switched off for long period (i.e. 3 months or more), it may happend that battery is totally drained and you will have to charge it again.

 

This means that you should be periodically (every 3 months) checking your device, and charging it to 80-90%.

 

In case that battery got deeply discharged, and internal protection system engaged- you need to leave your ENC connected to the charger for prolonged time- 3-4h. After 10-20min it should turn on, and charge normally.

Before that, check if ENC was not flooded.

After charging ENC, it does drain the battery very slowly (for automatic depth offset measurements). Discharge during a week-two should be a maximum  few %. Please remember that % display is indicative only, however in case of observing a strong discharge- to 0%… 40%… 70%…. consider:

  • after a shock impact- hit, for example during transport, ENC can turn on by itself and start working.
  • unless the auto OFF function in the menu is active, the console can drain in this way even a whole battery.
  • even when auto OFF is active, with subsequent switching ON, the console can drain the battery substantially.

Above should be accounted for when the console is transported. There is currently no possibility of eliminating this behavior, with simultaneous keeping a good sensitivity/ operability of piezo buttons.

If the console is not powering up after software actualisation, if all conditions from ENC manual were kept – you can try following procedure:

-connect charging cable to the console- without USB power source, only cable itself.

-leave console in safe place for min. 3 h (the best- overnight- 8-12h) with the cable connected, without direct sunlight, in cool spot.

-without moving the console, or touching the buttons- connect the power source.

If the screen will not light up afterward- it may indicate some other problem, the best to contact Seacraft Service.

ENC2 specific

  • My ENC2 does not charge

When you cannot charge your ENC2 console.

  •  Switch off the ENC2
  • Make sure that both cable and socket are clean, not corroded, and no debris is inside.
  • Connect the charging cable to the ENC2 first. Make sure it was pushed to the end.
  • Connect the other end of the charging cable to PC USB port or to the wall charger
  • Observe, if the ENC2 is switched on automatically. If not – the cable or the power source may be broken.

 

When the charging process takes long time, try to rotate the plug inside ENC2 about 45 degrees to the left (counter-clockwise) or to the right (clockwise) few times, during charging. If this helps, the charging cable or the charging port inside ENC may be weared out and require repair in our service.

ENC3 specific

  • I have problem with USB connection

USB connection is possible only using ENC3.

Data transfer is possible only when ENC console is put in the „Send data” mode BEFORE connecting to the PC.

 

When you connect your ENC console to the PC, and data transfer fails.

– Find how to run the „Device Manager”

– Make sure there are no „unknown devices” shown in it, when ENC is not connected (install required drivers). Unknown devices may affect the communication process in an unpredictable way.

– Put the ENC console in communication mode (Menu→Setup→Send data…), then connect the charging cable to the console, and then USB plug into PC.

– Go again to the „Device Manager” and check, if now is there any „Unknown device” (shouldn’t be).

 

When you see „Unknown device” while connecting ENC console to the PC, disconnect it (don’t change the „Send data” mode in ENC) and reconnect again. If there are still „Unknown device” in „Device manager” :

– try to use another USB port

– disconnect (temporally) any other USB devices

If none of this advices helped, try to install manually drivers delivered by our support team.

If this also didn’t help, maybe the USB cable require exchange (broken data lines).

 

 

DPV's general topics

  • I just unpacked my scooter and it does not work.
  • I have problem with opening my scooter's hull- it is very hard.
  • My scooter does not charge to 100% - how does the % calculation work?

Every Seacraft scooter is sent with disconnected main battery connector- for safety reasons

You have to open the unit, and connect the battery.

After trimming, scooter does not to be opened at all- as it is externally charger. However there are some tips which will make opening the body easier:

  • make sure that cap nut is completely removed
  • stand on the noozle- it is strong!- and move gently left/right with the tube, simultaneously pulling it upwards
  • before reassembly, apply dedicated Seacraft seals grease to the o-rings. It is also good to grease internal part of the tube- where it covers the o-rings what will make opening of the body easier.
  • Transport handle attached to the body helps significantly to pull the tube up.

With time, grease on seals is being squeeed away by o-rings compression, what will make it more difficult to open after for example a year of inactivity. Greasing the inner part of the tube ensures that after one harder move, the whole process will be easy even after long closure times.

There will be never a 100% charge displayed- maximum percentage is 99% (due to the displayed numbers limit)

If your scooter shows 96-99% after charging completion, everything is good and it is normal behaviour.

Some information about how Seacraft battery % display algorithm work.

  • Seacraft used enhanced voltage- based algorithm, which accounts battery voltage, it’s internal resistance, and load
  • It provides relativelly precise indication and information about battery charge %- however, some factors may influence it’s display
  • In high temperatures internal cell’s resistance decreases, in cold ones- increases. This leads to behaviour similiar as when loading diving tanks- hot battery will read more %, and after cooling down it can read even few % less.
  • Charging stops automatically when reaching certain battery %. This means that in high temperatures charging will stop earlier.
  • Another factor is scooter’s work. When battery is loaded, it delivers power- what leads to power drain, and voltage drop. If starting scooter immediatelly on high gear, it may cause a sudden battery % drop by few percents

 

Another very important factor is correct setting of battery installed in the DPV– each battery has different charcteristics, and assagning wrong battery type may influence the readings.

Future specific

  • I have problem to trim my unit in fresh water- nose is too light.

Seacraft engine is located- due to unique construction- on the end of the scooter. This locates a big mass on the end of the scooter, which- to achieve neutral trim- need to be countered.

In case you have one of the 2017 series scooters, it may require moving the battery and weights to the absolute tip of axial pipe. In case that you are mounting for example also a ENC navigation console on the scooter, you may want to ask us for new weight mounting system- which allows to move it even closer to the front:

Ghost specific

  • What is buoyancy backup in Ghost1500 and Ghost2000?
  • I cannot discharge the batery- it is my 6th dive, and battery is still over 50%

Ghost 1500 is often chosen by videographers and divers assembling a lot of extra gear onto DPV, becouse it has ~1200g of buyoancy backup in fresh water.

Ghost 2000 has maxed-out battery capacity, still providing ~200g of lift in fresh water.
In salt water (38 promiles salinity) both units will have ~600g buoyancy backup more.

Buoyancy backup determines how much weight (negative buoyancy) can be assembled on the scooter, and still trim it neutral.

You have probably the best scooter on the market. It is normal- do not worry, and… tighten the mask strap.

  • Are the Seacraft SLX3 lights still available?

As all Seacraft products are manufactured in Poland, production cost of SLX3 lights was too high for making them market attractive. Instead we are providing ball mounts, allowing for assembly of any kind of the light, and E/O external cord from the DPV battery- which allows to connect any E/O light head directly to the DPV.
