RTCU AX9i eco Technical Manual V1.01

Power supply

The RTCU AX9i eco unit can be supplied with either 85-265VAC (50/60Hz) or 8-36VDC or both
supply types simultaneously.

The RTCU AX9i eco also contains an internal low capacity backup battery, which will supply the
RTCU if the external power should fail or be disconnected. By default the RTCU AX9i eco is
powered down when a power fail occur. This setting however can be changed. Please consult the
RTCU-IDE on-line help for more information.

When the wakeup/ignition input is activated with a logical high, the RTCU AX9i eco unit will
wake up if it was in power down mode.

There are five different ground labels: External Ground (XGND), Signal Ground (SGND), Digital
Ground (GND), Analog Ground (AGND) and AC power ground (PE). The signal, digital and
analog grounds are filtered from the power ground. The signal, digital and analog grounds are
filtered from the power ground. External ground must only be used as DC power supply return
path. The digital ground is used as ground reference for digital I/O’s, signal ground is used as
ground reference for serial interfaces, and the analog ground is used as a low noise analog ground
reference for the analog inputs.

Dual Supply Note:

The RTCU AX9i eco unit can be supplied with both VAC and VDC at the same time. The unit will
run on the VAC supply if the VDC supply voltage is < +16VDC. If the VDC supply voltage is
higher it will run on the VDC supply.

Please refer to the RTCU on-line help for information on how to check the supply type from within
an application.

DC Supply

The RTCU AX9i eco unit can be supplied with 8-36VDC from an external DC power source.
Positive power is applied to the DCIN pin and ground is connected to the XGND pin.

The DC supply of the RTCU AX9i eco is protected against wrong polarity. If a system ground are
connected to either SGND or AGND a wrong polarity on the supply lines will destroy the internal
GND connection.

Please Note:

Minimum 16VDC supply is necessary for digital inputs 1-4 to work as S0 compliant inputs.

RTCU AX9i eco Technical Manual V1.01

Please Note:

The DC ground of the AX9 series is isolated from the AC ground because of the nature of AC-to­DC converting. As these two grounds are not tied together anywhere in the AX9, the DC ground
may appear as "floating ground" to the outside if the AX9 ground is not connected to the same
reference as the outside, and a potential difference may occur. This difference can interrupt the
behavior of the unit, and in worst case can damage the part of the unit. This must be taken in
consideration when the AX9 series are supplied with AC supply. When the AX9 is supplied with
DC voltage this "potential difference" issue may not be observed, as the DC power supply has
usually the same potential as the rest of the system.

In order to avoid the potential difference the Earth connection on the AC supply rail can be
connected to the terminal that has been labeled “PE”.

For circuitry in situations where significant Earth ground currents can flow isolating the DC
ground from Earth grounds may be desired. In this case the DC ground may be tied together with
the Earth ground through a high impedance connection.

In other situations where a common reference needed the best EMI performance and ESD
immunity can be achieved connecting the DC ground and Earth ground with a low-inductance
connection.

RTCU AX9i eco Technical Manual V1.01

Digital I/O

The RTCU AX9i eco unit has five digital inputs and four normally-open relay outputs.
The outputs are high performance relays with good current handling capabilities.

Digital input 1-4 offers several operation modes. Please refer to the digital input section for
additional information.

Relay outputs

The digital outputs control four relays and they act like a normally-open contact, where one side
must be connected to a source that needs switching and the other contact terminal is the output.
The source can be either VAC or VDC but the maximum switchable voltage and current must not
be exceeded, please refer to specification page.

There are no internal connections to the relay outputs and therefore a source must always be
connected to one of the relay terminals for the output to work. If power is removed or a power-fail
occurs on the RTCU AX9i eco will switch to normally-open.

The RTCU AX9i eco unit offers a very advanced power management, which makes it possible to
have one or more outputs enabled while the RTCU is in low power mode. Please consult the RTCU
IDE on-line help for more information.

Load Noise

If highly inductive loads (such as high power contactors) are connected to the relays it is
recommended to externally connect a clamping diode in parallel with each inductive DC load or
connect an RC snubber circuit in parallel with each inductive AC load.

For DC applications Vishay UF5405-E3/54 or similar is recommended and for AC applications
AMPOHM FE-SP-HDR23-47/100 (47nF/100 ohm) or similar is recommended.

RTCU AX9i eco Technical Manual V1.01

Digital inputs / S0 inputs / wakeup (ignition) input

The five digital inputs are all low-pass filtered (450kHz) and transient-protected. To activate the
inputs, connect a positive voltage between the corresponding input (DINx) and SGND.

Digital input 1-4 can be configured individually as S0 input (IEC62053-31, Class A) and DIN5 can
work as a wakeup (ignition) input.

As default the digital inputs are configured as normal inputs. For placement and configuration of
the hardware jumpers inside the unit, please refer to the configuration guide in Appendix A.

S0 compliant inputs (IEC62053-31, Class A compatible)

In S0 configuration the relevant RTCU AX9i eco input will act as a ‘pulse input device’, and a
current is supplied into the input connector so that a simple switch between SGND and the
appropriate input will activate it. This is used in most electricity metering equipment.

Please note: The RTCU AX9i eco unit must be supplied with a minimum of 16 VDC or AC power
for the S0 mode to work correctly.
S0 is enabled by default and may be disabled by the application to save power.

RTCU AX9i eco Technical Manual V1.01

Wakeup (ignition) input

The DIN5 / wakeup (ignition) input is a special input in that it also functions as the wakeup input.
If the input is activated with a logical high or low (Wait For Event mode only) when the RTCU
AX9i eco is in low-power mode it will wake-up the unit. A power apply will also wake the unit up
if it is in power-down mode or in Wait For Event mode with power Apply and/or ignition selected
for wakeup. The input is de-bounced with a period between 1-2 ms when used as a digital input.
So any logical level applied to this input must be greater than 2 ms to be valid.

The power management allows for the possibility of configuring a wakeup on one or more digital
inputs with individually configured falling- or rising edge detection. Please consult the RTCU IDE
on-line help for more information.

Analog input

The RTCU AX9i eco unit has two analog inputs which can be configured individually to work
either as voltage or current measurement inputs by using the configuration jumper. The range in
voltage mode is 0-10VDC and in current mode it is 0-20mA.
The conversion resolution is 12 bit.

By default the analog inputs are configured as voltage inputs, and are converted to a digital value
with a resolution of 10-bit before being presented to the application (0..1023). The application can
change the resolution to the full 12 bit (0..4095). Please consult the RTCU IDE for further details.

The input signal is connected between AINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise sensitive. Avoid long, unshielded wires and high current, fast changing signals routed
parallel to the analog signals.

1-Wire bus

The 1-Wire bus is available on the angled front row terminals. All 1-Wire communication goes
through a single connection, and all 1-Wire devices connected to this connection retrieves its
power directly from the bus (called parasitic power). For this only two wires are needed – the 1­wire signal and the ground reference – allowing minimal cable installations.

For 1-Wire ID-Button readers, which include a built-in LED, a dedicated output is available for this
purpose. Please consult the RTCU IDE documentation for further information.

DIP switch

Switches

DIP-Switch

The RTCU AX9i eco unit contains four dipswitches, where three of them are available for the
application to use (fourth dipswitch is reserved for GSM antenna switching.) The dipswitches are
located inside the unit (see drawing below or graphical view)

System switch (RST)

The RTCU AX9i eco unit contains a combined reset/diagnostic switch. This switch is accessible
from the inside of the unit (see drawing below or graphical view) It's necessary to use a small object,
for example the tip of a pencil.

By activating the switch shortly the RTCU unit will do a complete reset, as if the power was
removed and reapplied.

If the reset switch is held down for approx. 3 seconds3 the unit will enter recovery mode4 where the
application will not be started. In recovery mode the system will automatically turn on the GSM
module to establish a connection to the GSM network and RTCU Gateway (if configured). This
method will also activate the unit when the unit is in power-down mode.

System switch

RTCU AX9i eco Technical Manual V1.01

Internal Li-Ion battery

The RTCU contains an internal Li-Ion battery for operation even when the external power is absent
making it possible to report power loss etc. Please note that when external power is removed, the
unit will be powered down by default. This setting can be changed as documented in the RTCU
IDE documentation.

The relay outputs will be disabled when a power fail occurs as the internal battery cannot provide
the supply voltage needed.

The battery charging is completely automated and handled internally by the RTCU unit – leaving
no need for user interaction. Different kinds of functions (Battery low, Charger enable, Charging
status, etc.) are available to the user application.

The charge current is relatively high, for a shorter charge time, as specified in the technical
specification. Make sure both power supply and cables can handle the high current.

The battery will be charged whenever a power fail has occurred to establish the capacity thus
making the battery ready for the next power fail. A maintenance charge will start every 20 days
after the last charge. This is to compensate for the battery self-discharge etc.

By default the battery cannot be charged above 45°C or below 0°C. The RTCU offers charging
down to -10 ˚C using a specialized algorithm to protect the battery.

If the temperature is above 45°C the charging will not start and will be postponed until it is below
this threshold.

The temperature has a very high influence on the battery capacity. At 0°C the capacity has
dropped to 60% of the initial capacity and it falls dramatically at lower temperatures.

The battery cycle (numbers of charges and discharges) also influences the capacity. After 300
cycles the capacity has dropped to approximately 80% of the initial capacity.

Warning

Misusing the RTCU unit may cause the built-in battery security circuit to be damaged.

• Do not place the RTCU unit in high temperature locations such as in direct sunlight or near
engines. Using the RTCU unit in this environment may result in loss of battery performance and a
shortened life expectancy.

• Do not expose the unit to water, salt water or allow the battery to get wet.

• Avoid strong impacts and shocks.

For more information regarding the environmental limitations, see “Specifications for RTCU AX9i
eco” below or consult the RTCU AX9i eco datasheet.
