Figure 11 - DIN rail
The mounting procedure is described below:
• Switch off the power supply.
• Attach the module’s rear bracket on the upper DIN rail.
• Press the lower front panel gently until a click confirms that the bracket is fit on the rail.
• Verifying the module is anchored firmly to the rail, although lateral movement is possible.
Figure 12 - Mounted
The module is dismounted from the DIN rail as follows:
• Switch off the power supply.
• If necessary, disconnect the bridge(s) connecting the module to the system bus.
• Holding the module by the front panel, push the upper metal tab downward. The user can
also pull the tab down using for example a screwdriver as shown in
Figure 13 - Dismount
• Pressing the tab, remove the module from the lower DIN rail.
• Once detached, the module can be removed easily.

There are several options to implement the Synchrocheck functionality. The project’s engineers
should analyze them to apply the best solution.
Command from an AB_DO
The close command is transmitted from the relay contacts of an AB_DO.
Figure 16 - Synchrocheck application – Close command by the AB_DO.
In this case, Synchrocheck operates as follows:
The AB_DO module will execute the close command only when the signal CLOSURE_ENA
defined in coreDb is 1, indicating that both lines are in optimal conditions of synchronism.
The direct measurements module triggers the digital output at the same time that activates
CLOSURE_ENA in coreDb. The output signal will remain active, while synchronism conditions are
satisfied or the switch closure has not been detected.
When any synchronism condition fails, the direct measurements module will deactivate the digital
output , so the signal CLOSURE_ENA will be set to 0 in coreDb; therefore, the digital output will not
be activated by the AB_DO.
• Advantages:
o The close command is completely safe, since the commands transmitted from an
AB_DO are supervised. Thus, the generation of unwanted commands due to a
simple failure is not possible.
• Disadvantages:
o The command is conditioned by the bus management delay, database management,
logic programs, etc, so a slight and random delay might occur, even though this delay
is admissible in most cases. There are also configurable time parameters that can be
adjusted to the output activation relay.
o The presence of an AB_DO module is required.
07/05/2020
User Manual – AB_AC
Page 28
R&D Digital Seville
It is important to note that we have to define in coreDb the CLOSURE_ENA signal. We must
always configure the required times for the correct function of this mechanism).
Command from the AB_AC module DO
The close command is transmitted directly from the relay contacts connected to the existing
AB_AC digital output.
Figure 17 - Sychrocheck application – Close command by the AB_AC.
When relay closure conditions are satisfied, the direct measurements module will activate the
digital output which is directly wired to the relay. At the time that any of the conditions of
synchronism fails or the relay is closed, the module will disable this signal.
• Advantages:
o The delays since the synchronism condition is satisfied until the relay is enabled are
minimal. This delay corresponds basically with the relay delay itself, so it is a
determinist delay. This time can be included in the configuration parameters, in order
to advance the output activation to correct for the relay delay.
o An additional AB_DO module is not required.
• Disadvantages:
o The AB_AC digital output does not integrate the sophisticated security method
available in the AB_DO outputs. Although very unlikely, a fail in the transistor when
short-circuited may generate a close command in unwanted situations. When the
output is connected to the digital input, if a fault occurs on the output, an alarm will be
activated, although it is the user who should take appropriate actions.
Combined Command (AB_DO + DO of AB_AC Module)
In this case, the two outputs, AB_DO and AB_AC modules, will be wired serially.
Figure 18 - Synchrocheck application – Close command by the AB_AC and AB_DO.
When optimal synchronism conditions are satisfied, the direct measurements module’s contact will
close and this will activate the signal CLOSURE_ENA in coreDb. Only if a close command is

This is the most recommendable option, especially if there is in the system any AB_DO with a
R
received from the AB_DO during the time when CLOSURE_ENA remains active, the command will
be completed and the switch will close.
While the AB_AC digital output is open, a close command cannot be executed from the AB_DO.
• Advantages:
o The command is very safe, as the condition is transmitted by an AB_DO command.
o The delay between the optimal condition of synchronism and the relay (AB_DO)
triggering is practically zero if the delay introduced by this relay was indicated in its
corresponding configuration parameter.
• Disadvantages:
o The presence of an AB_DO module is required.

To perform the operations described in this chapter, the user must be familiar with the Easergy
4.1 ITB Configuration
Builder tool. Otherwise, please refer to the tool's manual.
In the Workspace of Easergy Builder, create a new RTU using button or pressing right button
of the mouse in an empty area of the RTUs tree:
Figure 19 - Adding new RTU.
Pressing button next to the graphical ITB, you can add, remove or change the I/O modules
included on the default configuration.
The user needs understand some basic concepts about Saitel DR before configuring the
acquisition:
• An ITB is a set of acquisition blocks connected to a CPU (HU).
• An Acquisition Block or AB is a Saitel DR input/output module.
• Each acquisition block is allocated to a unique address in the ITB, the Node Number; this
number identifies both the module and its I/O points. In the case of HU_AF and HU_BI, the HU
has also a node number assigned (In this case, the HU node will take address number 1 and
cannot be changed).
• The procedure AAP (Automatic Addressing Procedure) is performed by the operator every
time an AB module is added, deleted, replaced or moved inside the ITB. It can be launched
manually or automatically by setting switch #3 in the HU module to auto (please, refer to “Saitel
DR Modules Manual”).
Figure 20 - Acquisition modules in a default configuration.
The number between parentheses next to each module's name is the node number. You can
select an AB and use buttons to change its physical position.
When “Auto Address” box is checked (by default), if you reorder, add or delete an AB, all
addresses are automatically recalculated matching their physical position in the rail. Address
number 1 is assigned to the AB closest to the HU module (for HU_AF or HU_BI, address number 1
will be attached to the HU itself).
If “Auto Address” box is unchecked, modules will retain the allocated address, ignoring any
changes made. If rechecked, the following message will appear:

Select an AB (click on the AB image) and use button to remove it.
Use button to add a new AB. Select the type of AB in the following window:
Figure 22 - Adding one (or several) AB.
If “Auto Address” is checked, you can add several AB at one time. This window allows selecting
the quantity of modules to be added. If “Auto Address” in unchecked, you only can add one AB
each time and you have to select the address to be assigned.
To create a new configuration, select RTU in the tree and pulse right button of the mouse or use
button.
Figure 23 - Adding new configuration.
If the field "Create acquisition points defined in the RTU" is marked, all points of the local
acquisition of the acquisition blocks included in the default acquisition configuration associated with
the RTU will be included in coreDb.
For example, if a HUe has an ITB with a AB_AO module, if "Create acquisition points defined in
the RTU", following points are generated:
• 4 digital inputs in Status table.
• 4 analog outputs in Setpoint table.
• The supervision points of each AB module.
At the end of the operation, the new configuration will appear in the RTUs tree. We double-click on
it, and the Easergy Builder tool goes into Configuration mode.

4.2.2 Sychrocheck
This application monitors and controls the status of a switch based on certain conditions of
synchronism.
Figure 30 - AB_AC Synchrocheck application.
When Synchrocheck is used, both analog and digital input/output signals have a special function.
With Synchrocheck, no current inputs are used. With respect to the three voltage inputs, only two
will be used. These two inputs must be connected to the same phase line but at both ends of the
switch. Its state will be controlled by the module, based on the user-defined synchronism
conditions.
The digital output is designed to manage the closure of the switch that interconnects the two
supervised lines, and the digital input to supervise the switch state.
The digital input is continuously checked to verify that the switch state matches the command sent.
If any discordance is detected, the module will activate an alarm to inform the user. The user will be
responsible of acting in accordance with the detected failure.
There will be discordance in case of wrong wiring or a failure in the switch.
Synchrocheck allows selecting between two working modes:
• Doubly Energized (DE mode) for energized lines in the two inputs.

• Single Energized (SE mode) for energized lines in only one input.
Both modes can be enabled at the same time in the same equipment.
(VMIN), the module will be working in SE mode.
In this mode, the device will continuously analyze the RMS voltages, frequencies and phase
differences between both lines. It will allow the switch closure when the phases match and the
voltage and frequency differences are within the configured limits.
It is possible to establish an additional restriction, setting up a low voltage limit, to prevent the
switch closure when one of the lines has a RMS voltage under the configured limit.
In this mode the closure permission command will be sent when the line conditions match the user
requirements. There are three possible situations:
• VRAVSD: VR input line alive and VS input line death.
• VRDVSA: VR input line death and VS input line alive.
• VRDVSD: VR and VS input lines death.
The equipment can be set to work under any combination of these three configurations. A line is
said to be alive when the RMS voltage level is above the configured threshold. Likewise, the line is
said to be death when the RMS voltage level is below the corresponding threshold.
and one to set the death condition. It should be considered that the alive condition threshold
must be always greater or equal to the death condition threshold.

following condition:
TDIG+TSWITCH is the time it takes the digital output to be processed until the corresponding
relay is activated. If this time is too large it is possible that when the closure is enabled, signals
are no longer in sync. This condition is set to avoid such situations. If satisfied, it ensures that
the relay closure will occur under the synchronism condition and when the phase delay between
the two signals is minimal.
In case the configured parameters were too restrictive, and the closure condition could not be
met, the closure command will be sent when the phase difference is lower than the configured
limit.

Apart from these signals, the user should define a set of signals in Easergy Builder, which will have
the AB_AC as destination, in order to configure the operation mode as manual or automatic.
When the automatic mode is selected, the system continuously checks the conditions configured to
order the switch closure. In manual mode, this check is only performed when the ENA value is
active. This is used in maintenance mode, to monitor the system with the assurance that it will not
execute any commands.
The signals to be mapped are:
• SW_ST: Switch status. (0 open / 1 closed).
• AUX_MAN: Selection of manual (0) or automatic (1) operating mode.
