Elektronikon Nano

The Nano replaced the Elektronikon Basic on small frames. If a customer complains the screen is blank but the unit runs, check the display ribbon before condemning the controller — the display and controller are separate boards.

Sensor inputs

Element outlet temperature (PT1000)
Package discharge pressure (4–20 mA)
Dryer PDP input (option)

Fault code lookup

Element Outlet Temperature Shutdown Element discharge over shutdown (typ. 120 °C / 248 °F on oil-injected).

First checks

Oil level and oil cooler cleanliness
Thermostatic bypass valve
Fan operation and cabinet filters
PT1000 loop resistance sanity check

See trigger conditions & affected models →

Motor Overload F21/F22 overload or motor thermistor tripped.

First checks

Reset overloads in starter box
Phase balance and supply voltage
Check for hard-turning element

See trigger conditions & affected models →

Pressure Sensor Error Transducer signal out of 4–20 mA band.

First checks

Connector seated and dry
Loop mA with meter in series
Replace sensor if signal drifts

See trigger conditions & affected models →

Fan Overload Cooling fan motor protector tripped.

First checks

Reset fan overload
Blade free and shroud clear
Ambient temperature

See trigger conditions & affected models →

Service Warning A service timer (oil, filter, separator) expired.

First checks

Do the indicated kit service
Reset only the counter for the work performed

See trigger conditions & affected models →

Emergency Stop E-stop circuit open.

First checks

Release E-stop
Check safety loop continuity

See trigger conditions & affected models →

Fault list is non-exhaustive and firmware-dependent. Always confirm against the controller’s on-screen help or OEM manual.

Sensor pin resistance & signal values

Pin-level resistance and signal values for the sensor types this controller uses. Works offline. De-energise the panel and lift one lead before ohming any element.

Wiring notes

CAN expansion modules auto-address at power-up — add/remove modules only with control power off
Pressure transducer wiring is shielded; land the shield at the controller end only
The Nano joystick doubles as the service-menu navigation — hold to confirm parameter changes

Known issues & field notes

Early firmware would lose the week-timer after extended power loss — update firmware if a unit keeps forgetting schedules
Joystick wear on high-use panels causes phantom menu entries — replace the encoder module

Service parameters sit behind a user-set PIN; factory menu is dealer level.
