===Output voltage selection===
 +
[[File:DPSI-Micro-SingleBat Spannungswahlschalter 640x400.jpg|thumb|left|Voltage selector DPSI Micro SingleBat]]
 +
The output voltage of the DPSI Micro can be selected in two steps: 5.5V/5.9V or 5.9V/7.2V. This can be done by selecting the desired voltage with the voltage selector.
 +
 
 +
Some servos are only approved for 4.8 volts according to their manufacturer's specifications (e.g. fast tail rotor servos for helicopters). Here, an output voltage of 5.5 volts is simply allowable. The manufacturer's values refer to 4-cell NiCad batteries. When fully charged, these batteries carry up to 5.5 volts, too. 4.8 volts are reached, when these batteries are almost discharged.
 +
 
 +
<div class="hint">Hint: Please see specifications of your receiver and servos.</div>
 +
 
 +
<div class="hint">The higher the difference between input and output voltage, the higher the power dissipation, which is converted to heat. In models with many servos it is advisable to select the higher output voltage at the DPSI Micro to limit the power dissipation.</div>
  
==Mounting==
+
<div class="caution">Due to drop out loss in the voltage regulation stages of the DPSI Micro systems, usage of 4-cell battery packs (NiCad / NiMH) is definitely NOT possible and is not permitted!</div>
The DPSI Micro must be fixed at the RC plane's fuselage inner sidewall. DPSI Micro Systems can be switched on and off contactless with an external magnet. So only a small drilling hole with five millimeters of diameter must be drilled into the fuselage. The battery backer can be glued with silicone or fixed with screws directly on the fuselage's inner sidwall.
 
<!--[[File:DPSI-Micro Bohrschablone 640x400.jpg|200px|thumb|left|Aufkleber und Bohrschablone]]
 
Der im Lieferumfang enthaltene Aufkleber dient zum einen als Bohrschablone, zum anderen optional als Anzeige der Schaltpunkte außen am Rumpf. Die Löcher an der Außenseite des Aufklebers sind die Markierungen für die Bohrungen. Diese Anschraubpunkte werden mit einem 3-Millimeter-Bohrer gebohrt. Das Loch in der Mitte ist für die LED gedacht und wird mit einem 5-Millimeter-Bohrer gebohrt.-->
 
  
Now feed the screws through the screwing holes. The screws serve as positioning helps for the self-adhesive foam rubber, which serves as vibration protection. It is pushed over the screws from inside and glued to the fuselage's sidewall. This anti vibration mat is not mandatory, but advisable especially for combustion engines. Possibly small fuselage unevenness is eliminated, too.

The DPSI Micro is now mounted with included M3 screws. The screwing collars enlarge the area of support and inhibit in this way damage to the fuselage. The screwing position of the DPSI Micro housing allows the screws to cut their way themselves. Don't tighten the screws too much, in order not to press the cellular rubber too extensively.

===Switching on and off===
 +
[[File:DPSI-Micro-SingleBat Schaltpositionen 640x400.jpg|thumb|left|Switching on and off position]]
 +
For switching on the DPSI Micro the included magnet must be placed over the switching on position (ON) for approx. one second. The magnet can be placed in a distance up to 8 millimeters. After switching on the selected battery type is indicated by a blink code (see table 2: Blink codes/Battery types)

In general, load capability and capacity of the batteries must be observed. As far as the selection of capacities is concerned, also consider, if you want to recharge the batteries between flights or if you want to operate the model all day long without recharging.
A capacity of 1000mAh usually suffices for a F3A combat model. When using a DualBat system we recommend 2 batteries starting from approx. 600mAh.

===Battery failure===
 
If a battery fails when used for a DPSI Micro, (e.g. cable broken or battery defective), the LED flashes continuously fast (5 Hz). This error type has highest priority. If the outage is removed during operation, the blinking still continues! So it can be determined after landing that the batteries or the connections should be checked.

If the voltage of battery 1 drops below a certain value, this blinking code is output. The capacity of the battery usually suffices for one more flight before recharging is necessary.

If the error is qualified once, it stays active until turning the DPSI Micro off.
 
 
If both batteries of the DPSI Micro - DualBat indicate low voltage, both error codes are output alternatively.
 
 
Low voltage errors have lower priority than battery malfunction errors. Error output for battery malfunctions therefore is interrupted.

Mounting suggestions

DPSI Micro Systems can be switched on and off contactless with an external magnet through the model's fuselage wall or with the transmitter, so they can be fixed at the fuselage inner sidewall. The switching on and off process with the magnet works up to a distance of about 8mm (0.3in) from the DPSI Micro's surface through the fuselage wall. To see the LED from the outside a small hole with 5mm (0.2in) diameter can be drilled in the fuselage wall.

Sticking on the DPSI Micro system

The DPSI Micro can be sticked on with silicone directly on the fuselage's inner sidewall.

Screwing on the DPSI Micro system

The DPSI Micro can be screwed from the outside to the fuselage wall. The required holes can be drilled using the included drilling template.

Both screws can be feed through the drilling holes from the outside. The screws are positioning helps for the self-adhesive foam rubber, which can be used as vibration protection. It is pushed over the screws from inside and glued to the fuselage's sidewall.

The vibration protection is not mandatory, but advisable especially for engine models with higher possible vibrations. Possibly small fuselage unevenness is eliminated, too.

The DPSI Micro can be mounted with two included M3 screws. The screwing collars enlarge the area of support and inhibit in this way damage to the fuselage.

Don't tighten the screws too much, in order not to press the cellular rubber too extensively.

Operating

Output voltage selection

Voltage selector DPSI Micro SingleBat

The output voltage of the DPSI Micro can be selected in two steps: 5.5V/5.9V or 5.9V/7.2V. This can be done by selecting the desired voltage with the voltage selector.

Some servos are only approved for 4.8 volts according to their manufacturer's specifications (e.g. fast tail rotor servos for helicopters). Here, an output voltage of 5.5 volts is simply allowable. The manufacturer's values refer to 4-cell NiCad batteries. When fully charged, these batteries carry up to 5.5 volts, too. 4.8 volts are reached, when these batteries are almost discharged.

Hint: Please see specifications of your receiver and servos.
The higher the difference between input and output voltage, the higher the power dissipation, which is converted to heat. In models with many servos it is advisable to select the higher output voltage at the DPSI Micro to limit the power dissipation.
Due to drop out loss in the voltage regulation stages of the DPSI Micro systems, usage of 4-cell battery packs (NiCad / NiMH) is definitely NOT possible and is not permitted!
Table 3: Recommended output voltage
Application Recommended output voltage
Tail rotor servos, helicopters with quick gyros, servos for 4.8V according to manufacturer's specification 5.5V
Gliders, small motorized models with up to approx. 5 servos 5.5V oder 5.9V
Aerobatic models, jets, models with more than 5 servos 5.9V
Competition models (motorized aerobatic flights) 5.9V

Switching on and off

Switching on and off position

For switching on the DPSI Micro the included magnet must be placed over the switching on position (ON) for approx. one second. The magnet can be placed in a distance up to 8 millimeters. After switching on the selected battery type is indicated by a blink code (see table 2: Blink codes/Battery types)

For switching off the DPSI Micro the magnet must be placed over the switching off position (OFF) for approx. two seconds. The distance can be also up to 8 millimeters. The LED goes off and the receiver system is currentless.



Batteries

Battery types

As far as batteries are concerned, commercially available types are in use: NiCad, NiMH, Lithium-Ion (LiIon) and Lithium-Polymer (LiPo). Independent of the selected output voltage, these batteries are unlimited usable. Load capability should ranch from 3C up to 10C corresponding to the application.

Battery mounting

If the battery is placed in greater distance from the DPSI Micro due to the balance point reasons and so the connection cables are long, it is usefull to twist the wires. So better interference suppression is ensured.

DPSI Micro systems are not reverse polarity protected. Please be sure that the batteries are always connected correctly. The red pole must be connected to plus the black pole to minus.

Recommended battery capacities

In general, load capability and capacity of the batteries must be observed. As far as the selection of capacities is concerned, also consider, if you want to recharge the batteries between flights or if you want to operate the model all day long without recharging.

Table 1: Recommended battery capacities
Application Recommended capacity
F3A models for competitions, small gliders with up to 5 servos 1000mAh
Helicopters with fast tail rotor servos 1500mAh
Aerobatic models and small jets with up to 7 servos 2400mAh
Large gliders with up to 10 servos 3300mAh

Battery programming

Because DPSI Micro uses intelligent voltage monitoring, the used battery type must be programmed once. The programmed type is stored in the micro controller of the DPSI Micro until eventually newly reprogrammed.

Starting programming mode

Programming starts when the voltage selector (see picture 1) is moved from one position to the other within 10 seconds of turning on.

Hint: The voltage difference of the output voltage must be at least 0.5V when switching the voltage selector switch. An (almost) empty 5-cell battery provides only 5.5V, Therefore, the output voltage of the DPSI MICRO does not change when switched between 5.5 and 5.9V and the programming mode is not entered!

Programming

As soon as programming mode starts, the LED is turned on for 3 seconds. Then a 3 second dark phase follows. This indicates "programming mode".

Now blinking codes for the specific battery type will be shown followed by 3 seconds break (see table 3). As soon as the desired type is indicated, the programming mode must be left within 3 seconds in advance of the next blink code. Programming mode is left by putting the sliding switch back to its previous position. The selected battery type is stored.

Table 2: Blink code/Battery types
Blink code Battery type Nominal voltage
1x Blink 5 NiCd/NiMH cells 6.0
2x Blink 6 NiCd/NiMH cells 7.2V
3x Blink 2 LiIon cells 7.2V
4x Blink 2 LiPo cells 7.4V
5x Blink 2 LiFePO4 cells 6.6V
6x Blink 7 NiCd/NiMH cells 8.4V
7x Blink Deactivate tests / no error indication ---

If “7x blink” is selected (all tests disabled) the DPSI Micro does not monitor voltages. No empty batteries or other errors are indicated!

Hint: By default, battery type 2 cell LiPo battery (4x blink) is programmed at delivery.

Error indication low voltage of battery

Error indication

The central LED indicates error types through blinking codes.

If the voltage of battery 1 drops below a certain value, this blinking code is output. The capacity of the battery usually suffices for one more flight before recharging is necessary. Nevertheless, the battery should be recharged anyway if this error code is displayed, assuming the correct battery type is programmed. This error code is repeated in a sequence of 6 seconds. If the error is qualified once, it stays active until turning the DPSI Micro off.

Safety note

The switching off process of DPSI works with a hall effect sensor. Hall effect sensors can be influenced by magnet fields. It is possible that the DPSI switches off when exposed to a very strong magent field (i.g. electric drive). Current-carrying cables generate a magnet field. So please run all cables which are carrying a high current (>100A) with a distance of at least 3cm (1.18in) from the DPSI.
