The serial number of the S-Bus, M-Bus or Modbus one-phase and three-phase energy meter is printed on the front of the energy meter and it's also possible to read out the serial number over the communication interface.

Until June 2013 the two serial numbers were different one from the other, but each one was unique.

Energy meters produced since June 2013 does have the same serial number on the front of the energy meter and read out over the communication interface.

This change has been implemented in all energy meter with production date 1322 or later.

This applies to one-phase and three-phase energy meters with S-Bus, M-Bus or Modbus communication.

Note also that the format of the serial number has changed for the S-Bus and Modbus (is now ASCII) and due of this it's necessary to use an aditional register to store the serial number.
The new used register was not used on the energy meters with production date < 1322.

In the M-Bus library for the SBC Energy Meters (which can be installed for PG5 1.4, PG5 2.0 and PG5 2.1) the following modifications have been applied.

Modification in the SBC MBus library 2.7.006 (March 2013)

• Added support for PG5 2.1
• Removed the option "BACnet"
  

Modification in the SBC MBus library 2.6.113 (December 2011)

• Added outputs of the FBox: total active power and total reactive power is now provided

Modification in the SBC MBus library 2.6.104 (July 2011)

• A negative reactive power measured by SBC M-Bus Energy Meters was displayed incorrectly
• Support of the new modules PCD2/3.F271(0), F272(0) and F273(0)
  If you use such a module, please configure the "Serial line" in the driver FBox to "M-Bus/F27xx" and ensure you have the firmware 1.16.52 or later on the PCD.
  With older library version, you don’t have this option and you can only use the modules PCD2/3.F270(0) with the mode "RS485/F270".

• With the M-Bus library 2.6.013 the driver sent M-Bus resets repetitively
• With older versions than 2.6.014 the SBC M-Bus Energy Meters were not always correctly connected.

• There exist two libraries for M-Bus:
  - The "full version" from Engiby
    which supports all the M-Bus Energy meters from SBC, but also from other manufacturers
  - the "SBC version"
    which supports only the M-Bus Energy meters from SBC.
• The "SBC version" is available from the support site;
  for the "Engiby version" please contact Engiby in order to obtain the last version. www.engiby.ch 
• Please do install the "SBC version" or the "Engiby version" but not both in parallel; this could lead to inconsistent file combinations.

Due to a firmware problem it isn't possible to use the following S-Bus addresses for the energy meter ALD1, ALE3 and AWD3:

107, 153, 226 and 238.

Symptom
If one of the addresses 107, 153, 226 and 238 is used, the energy meter does not answer to any request of the S-Bus master. Further on it is no longer possible to change the S-Bus addresses of the S-Energy Meter.

Reason
Due to an error in the firmware the S-Bus interface of the Energy Meter does no longer work after one of the above mentioned addresses has been configured. Further on it is not possible to change the address back to another address.

Solution
Please return the concerned device (which has configured one of the addresses 107, 153, 226 or 238) to the repair service of Saia-Burgess Controls AG, with the indication that the S-Bus address can no longer be modified.

This error was fixed since the following firmware versions (first delivered in November 2010):

Remark
The S-Energy meter with Modbus or MBus interface are not concerned.

In case a current transformator and a transfomer ration other than 1 (5:5) is used for measuring the energy with an AWD3 (with Serial-S-Bus interface) the FBox from the library 2.6.156 or older do not correctly display the current.

Symptom
The current displayed in the FBox is not correct if a current transformator is used for measuring the energy with an AWD3 (with Serial-S-Bus interface). Instead of e.g. 50 Ampere, 5.0 Ampere are displayed.
 
Reason
In case a transformer ratio other than 1 is used the AWD does send the current as [Ampere] (if the tratio is 1:1 the current is in the format x.x Ampere.
The FBox library version 2.6.156 (or 2.5.156 for PG5 1.4) and older do not consider this difference.

Solution
This problem will be corrected in the next FBox library version. 

On energy counter AWD3D5WS00C3A00 and AWD3D5WS00C2A00, the cos value on phase 1 ist correct but not on phase 2 and 3. All other values are read correctly.

As the cos phi value can be calculated with the active and reactive power it isn't a major problem!

Correction:
This problem is correct on all modules from production date 1034.
The production date is imprinted on the right side of the housing, below the CE indication.

The S-Bus address of an ALE3 with Serial-S-Bus interface can be configured by the following procedure.

Setting the S-Bus address

• Navigate to the "Tariff 1 total" (the blue bar must be right below "T1total"; it can be moved with the "arrow down")
• Press the button with the "arrow right" (>) during 3 seconds
• Change the address to the value desired
  the "arrow down" increments the address by 10
  the "arrow right" increments the address by 1
• Once the correct address is displayed/set, wait for until the display turns back to the default display (after around 10 to 15 seconds)

Because the energy meters have a slower S-Bus interface the "SASI S-Bus Master" FBox gets red when communicating with energy meters. This red LED can be ignored (or the FBox SEnergyInit can be used; this FBox does not get red on every retry but only if the Energy Meter does not answer at all).

Why  does the "normal" SASI S-Bus Master" FBox get red?
It is possible that an S-Energy Meter does not answer one Serial-S-Bus request from time to time (the retry of this request will be answered in every case). The "normal" SASI Master FBox does indicate such a retry with a red LED (which can be ignored).

What can I do against the red LED?
There are special FBoxes for the S-Energy meters with Serial-S-Bus. These FBoxes for the energy meter will remain green as long as the communication is working correctly (taking into account that a retry can happen from time to time). The performance of the S-Bus is only slightly decreased due to the retry time.



The minimal FBox library version which contains the "SEnergyInit" FBox

• PG5 2.0: 2.6.171 (file "Energy Meter S-Bus_V2_6_171_ml.exe") or newer
• PG5 1.4: 2.5.171 (file "Energy Meter S-Bus_V2_5_171_ml.saiazip") or newer

Please find the adequate FBoxes for PG5 1.4 and 2.0 to read the values of energy meters supporting S-Bus on our support site in section 'energy meters':
sbc-support.ch/Axx/Axx3_SBus.htm.  

Remark
Please note that the SEnergyInit FBox can only be used together with the AWD FBoxes (but not with "common" Send and Receive FBoxes for S-Bus).

In the Adjust window of the FBox for the AWD Energy Counter the display format of the measured current it not identical for all phases. While phase 2 and 3 have the format #.#, the phase 1 is missing the point.

Symptom
In the Adjust window of the FBox for the AWD Energy Counter the display format of the measured current it not identical for all phases. While phase 2 and 3 have the format #.#, the phase 1 is missing the point.
§ix101154§

Solution
This display problem is corrected in version

• 2.5.156 (for PG5 1.4) or
• 2.6.156 (for PG5 2.0)

Please update the library and then replace the FBoxes in your Fupla program.

In the english version of the FBox library for the Energy meters ALE3 with Serial-S-Bus interface the symbol names have been mixed up so that the same value appears as "T1part" and as "T2 part" (partial counter of tariff 1 and 2 are identical, equal to the one from Part2).

Symptom
With the version 2.6.100 (for PG5 2.0) and 2.5.100 (for PG5 1.4) of the FBox library for the Energy meters with Serial-S-Bus interface the output for the "tariff 1 partial" is wrong (contains always the value from the "tariff 2 partial") in the first places FBox of the Fupla. In the screenshot below, the T1part should be 31.7, but it is 0: 
§ix101145§

Reason
Unfortunately the same names have been used twice in the FBox:


Solution
Please download and install the latest library version (listed below) and re-insert he FBox to your Fupla!

• Version 2.6.155 or later for PG5 2.0.110
• Version 2.5.155 or later for PG5 1.4.300

If the current direction is inverted, for example if a PV installation does supply back the current, then the active power and the cosine Phi of the concerned phase on the AWD3/ALE3/ALD1 will have a negative sign.

The current is always displayed without sign (positive).

Behavior of the kWh counter:

In case of a non-bidirectional meter, the meter will display an error on the concerned phase and will not increment nor decrement the kWh counter with the measured power.

In case of a bidirectional meter, the meter will not display an error and will increment the corresponding kWh counter with the measured power.

Yes, the sign of reactive power does indicate the type of reactive power load.

If the reactive power is generated from a capacitive load then the sign will be negative.

If the reactive power is generated from inductive load then the sign will be positive.

Versions ALE3D5F11KC3A00, ALE3D5F10KA2A00 and ALE3D5F10KA3A00 have push buttons. The ALE3D5F10KBXXXX doesn't have them.

For other differencies please see the data sheet in the appropriate section of our website.

The AWD3 and AWD1 energy meters require 5A current transformers.
Since there are a lot of different transformer form factors and ratios, they can't be ordered at SBC. 
They are available from different sources.

An energy meter ALE3 or AWD3 does always show the consumed energy (as physical variable) on the LCD display on its front. It is also possible to temporarily display e.g. the instantaneous power measured, the energy meter will switch back to the display of the consumed energy after 20 seconds.

Can I cange this behavior?
No, it is not possible to change the unit displayed by default. Since the ALE3 and the AWD3 are energy meters, the norm EN 50470-3 is applied for the behavior of the device. This norm specifies that an energy meter must display the consumed energy by default.

The serial number of the S-Bus, M-Bus or Modbus one-phase and three-phase energy meter is printed on the front of the energy meter and it's also possible to read out the serial number over the communication interface.

Until June 2013 the two serial numbers were different one from the other, but each one was unique.
