Software Interaction
This section presents general operation of SmartStruxure Lite Building Peripherals, as
well as an overview of the different states of a Building Peripheral. This information
should be read in conjunction with the Device Behavior section to gain a full
understanding of the behavior of your Building Peripheral in different stages of
operation.
Scanning for Zigbee Networks
Wireless communication with your Building Peripheral requires the device join a
ZigBee network previously formed by one or more SmartStruxure Lite Managers.
A SmartStruxure Lite Building Peripheral can store in its memory the information
to connect to five different Zigbee networks. Your device discovers the available
networks in its communication range by doing a network scan.
The network scan occurs under one of the following two conditions:
• Automatic scan: when a SmartStruxure Lite Building Peripheral is powered up
and its internal memory contains no network information such as a new Building
Peripheral or device that was never connected to a Zigbee network.
• Manual scan: when the Building Peripheral network scan button is pressed for
more than five seconds and less than 30 seconds to initiate the scan.
If the network scan is unsuccessful and the device cannot find an available Zigbee
network, the device remains disconnected and stays in that state until a manual
network is initiated and a joinable network is found.
9
Joining a Zigbee network
After a successful scan, the Building Peripheral automatically joins the first Zigbee
network stored on its list. When the blue LED on the Building Peripheral stops flashing,
the Building Peripheral has joined a network.
If for some reason it cannot join the first network on the list before reaching a
programmed timeout, the device automatically tries to join the next network. The
device repeats this sequence until it joins a network on its list, or a manual network
scan is initiated to refresh its network list.
Refer to the following two sections for more details:
• “Procedure - Configure Zigbee” on page 10
• “Using Com Log” on page 14
Schneider Electric | II-SSL-SEC-TE-SED-0 -A4.EN.08.2016.v2 August 2016
Procedure - Configure Zigbee
NOTE: This procedure assumes you have already wired electrical power to your
device as per the wiring diagrams. For the purpose of this procedure, a SED-0
Building Peripheral is used. The procedure is identical for the SEC-TE except where
otherwise indicated. Also, ensure Devices tab on left side of Building Expert is
expanded before you start the procedure.

Peripheral for 6 to 30 seconds until LED begins flashing rapidly, Then release
Network Scan button.
The device begins scanning for all Zigbee networks within range and the LED flashes
slowly. When the LED stops blinking and illuminates solid, the Building Peripheral has
joined a network
Schneider Electric | II-SSL-SEC-TE-SED-0 -A4.EN.08.2016.v2 August 2016
Verify Configuration
1. Allow up to 30 seconds to pass, and verify device has joined correct network:
• Case 1: If device has joined correct network, Status field shows Online. Click
Save button.
• Case 2: If device has not joined correct network where more than one ZigBee
network is present, Status field shows Communication Error followed by
numeric error code.
NOTE: In Case 2, you must press network scan button again for approximately 2
seconds to skip to next network in list of stored networks. For each attempt, allow up
to 30 seconds for ZPC object’s status field to update. Once the device is online, click
Save button.

Schneider Electric | II-SSL-SEC-TE-SED-0 -A4.EN.08.2016.v2 August 2016
Using Com Log
In large installations where multiple ZigBee networks may be present, the Building
Expert’s Com Log is a useful, time-saving tool for determining whether your Building
Peripheral has joined the correct network.
To verify whether the Building Peripheral has joined the desired Zigbee network, you
must monitor the Zigbee activity on the Com Log window of the section Manager
where the Building Peripheral should be joining.
The Com Log should be accessed before starting the joining process to ensure you
see the Com Log entry of the device joining the network.
Access Com Log
1. In Devices tab, right-click on your section Manager.
2. Select Show Com Log.
The Com Log shows in a separate window, and the figure below shows a typical
message appearing on Com Log when a Building Peripheral joins the network.
14
The device is identified on the Com Log with an extended_id corresponding to its
MAC address. This address is unique and permanent for each device.
Note: When the device joins the network, the Device Announce message shows on
the Com Log several seconds before its status field on the ZPC object updates. Allow
the status field sufficient time to update to “Online” before clicking the ZPC object’s
Save button.
Schneider Electric | II-SSL-SEC-TE-SED-0 -A4.EN.08.2016.v2 August 2016
Joining Other Networks on the List
If the device joins a network (LED is ON) but does not appear on the Com Log, this
means the device joined a network from a list not detected on the desired network.
The list can contain up to 5 Zigbee networks.
To change the network, press the button on the device and hold it between 1 and
5 seconds. The blue LED flashes until the device joins the next network, and then
remains solid.
Each time you press the button, the device joins the next network on its list and cycles
continuously. If there is only one network available, it constantly attempts to rejoin the
same network.
Other Operation Scenarios
1. SmartStruxure Lite Building Peripheral loses power:
If a Building Peripheral joins a network at least once, it tries to reconnect to the
same network it was last connected to if it loses power and is powered back on.
If you want the device to join another network, you must do a new manual network
scan, since stored networks get deleted on power loss, with the exception of the
last joined network.
2. ZigBee Network goes down:
If the network to which a device is connected is temporarily unavailable, the
device tries to rejoin this network indefinitely. Once the network is back up, the
device rejoins it.
15
Perform one of the following if you want the device to connect to another network:
• Press the button on the device and hold it between 1 and 5 seconds to search for
another network on the list of discovered networks.
• Initiate a network discovery to find available networks.

Endpoint Descriptions
Analog Inputs (AI)
Each analog input is configurable via the ZPC1 object used with devices supplying a
signal in Ohms (thermistor, potentiometer, dry contact) or in Volts (analog temperature
or humidity sensors). By default, all analog inputs are set to Volts.
16
Analog Outputs (AO) – SEC-TE Only
• SEC-TE offers 4 analog outputs.
• Value assigned to the output can be between 0V and 12V. The output value has a
resolution of 12 bits.
Binary Outputs (BO) – SEC-TE Only
• SEC-TE offers (as an option) 5 relays/binary outputs.
• Each relay is rated for 5A at 24VAC.
Schneider Electric | II-SSL-SEC-TE-SED-0 -A4.EN.08.2016.v2 August 2016
Valve Digital Position (AI5) – SED-0 Only
• Current position of the SED-0 valve actuator is stored in AI5.
• Position is stored as a percentage, where 0% represents the valve physically in
position 0, and 100% represents the valve physically in position 1.
You cannot physically reverse polarity of the SED-0 actuator. If required, reversing the
polarity must be done inside your control script.
Valve Set Position (AO1) – SED-0 Only
• Desired valve actuator position is stored and can be edited in object AO1.
• Position must be defined in percentage, where 0% represents the valve physically
in position 0, and 100% represents the valve physically in position 1.
• You cannot physically reverse polarity of the SED-0 actuator. If required, reversing
the polarity must be done inside your control script, AV1 and AV2.
• Objects AV1 and AV2 allow you to store analog values in the SED-0 actuator
memory. These objects are used mainly in the Lua script embedded in the SED-0
valve actuator.
17
Lua Script
The SED-0 and SEC-TE can run a simple Lua script. This script can have a maximum
of 225 characters (including spaces) and is used mostly to create a fail-safe control
sequence when the ZigBee communication with the network is lost, or, to execute
simple control tasks.
Tip: Optimization is the key! Do not hesitate to contact our Support Team to assist you
in the development of an embedded script.
