Conditions
Specifications are valid under the following conditions unless otherwise noted.
The AL-1020 module is mounted in a standard NI SLSC chassis. This chassis should conform to
the NI recommended cooling requirements and use a standard power supply that meets the
specifications provided in the chassis user guide. All aspects of the SLSC chassis should follow
NI guidelines.
Please Note - These specifications only apply to the product as provided by ALIARO.
Modifications to the module may invalidate these.
Caution - Observe all instructions, warnings and cautions in the board
documentation. Using the module in a manner not specified by this document can
damage the module and compromise the built-in safety protection. Return damaged
models to ALIARO for repair.
Overview
The AL-1020 (Power Switch Board) board provides power switching capability (to for example,
test shorts in vehicles) and has fault insertion on all channels that allows users to switch output
between multiple signals.
The AL-1020 board is designed to fit National Instruments (NI) Switch Load Signal Conditioning
(SLSC) system together with corresponding computer interface boards and is delivered with
LabVIEW driver and a Custom Device for VeriStand.
The main purpose of the board is to be used for test and validation of Devices Under Test
(DUTs), testing for both software and hardware failures. This is usually done by incorporating the
board as part of Hardware-In-the-Loop (HIL) test system.
For easy board/system configuration, it is recommended to use the board alongside xMove
Configurator.

Installation
Electromagnetic Compatibility (EMC)
This product is intended for use in industrial locations. Harmful interference may occur in certain
installations, such as if the product is used in residential or commercial areas. This may also
occur when the product is connected to a peripheral device or test object that outputs
electromagnetic noise or other interference.
To minimize interference with radio and television reception and prevent unacceptable
performance degradation, install, and use this product in strict accordance with the instructions
of the product documentation.
Furthermore, any modifications to the product not expressly approved by ALIARO may void your
warranty and your authority to operate it under your local regulatory rules.
Caution
-
To ensure the specified EMC performance,
operate this product only with
Shielded cables and accessories.
Unpacking the module
The AL-1020 board ships in an antistatic box to prevent Electrostatic Discharge (ESD). ESD can
damage the device components. Users should be familiar with the steps to prevent ESD damage
when handling the device.
Warning - Never touch the exposed pins of the connectors.
To prevent ESD damage when handling the device, please take the following precautions:
- Ground yourself before handling. Use a grounding strap or by touching a grounded
object.
- Touch the antistatic package to a grounded metal part before removing the device from
the package. A good example would be the metal part of your computer chassis.
Remove the device from the package and inspect it for damages such as loose components.
Contact ALIARO if the device appears damaged in any way. Do not use a damaged device with
any other components. Store the device in antistatic protection when not in use.

Warning - Do not touch the contacts or remove the I/O boards or cables while the
system is energized. The SLSC chassis and the AL-1020 do not support hot plug-in.
The entire chassis must be powered off when a module is inserted or removed.
Installing the AL-1020
Warning - Do not touch the contacts or remove the I/O boards or cables while the
system is energized.
1. Power off the main DC power source or disconnect the power source from the chassis
before installing any modules or RTIs.
2. Ensure that the chassis is powered off. The POWER LED should be off. If the POWER
LED is not off, do not proceed until it is off.
Please Note - The SLSC chassis and the AL-1020 do not support hot plug-in. The
entire chassis must be powered off when a module is inserted or removed.
3. Loosen the screws on the upper rear panel of the chassis.
4. Position the RTI backplane at the desired slot and insert the securing screws, but do not
fully tighten them.
5. Insert an AL-1020module into the same slot as its corresponding RTI while firmly holding
the RTI in place until the RTI is fully connected to the module.
6. Repeat steps 4 and 5 for all required RTIs.
7. Fully tighten the screws for all RTIs and the upper rear panel of the chassis. Wait until all
RTIs and modules are installed before fully tightening the screws. This ensures the
proper alignment for future connections between modules and RTIs.

Software Installation - SLSC LabVIEW Drivers
When the module is used with LabVIEW or TestStand, the ALIARO drivers need to be installed.
Contact ALIARO support for the most recent version of our drivers: [e-mail]
Software Installation - ALIARO Custom Devices
When the AL-1020 is used with VeriStand, Custom Devices needs to be installed. Contact
ALIARO support for the most recent version of our Custom Devices: [email protected]om
Software Installation - ALIARO xMove Configurator (Optional)
xMove Configurator is a tool for defining and editing VeriStand System definition files for HIL
(Hardware-in-the-loop) test systems. It is specifically aimed at configuring ALIARO SLSC Multi-
Purpose boards and NI modules.
The configurator uses a Predefined System Configuration file containing the system mapping
and a VeriStand System Definition file defining all hardware. It empowers users to configure and
reconfigure User Channels, Aliases and System Mappings for HIL systems.
For more information on xMove Configurator, check the xMove Configurator webpage on
NI.com.
System Check
Finnish the installation by conducting a system check, see the chapter Operation.

Warning - Do not operate the device in an explosive atmosphere or where there may
be flammable gases or fumes. If you must operate the device in such an
environment, it must be in a suitably rated enclosure.
System check using LabVIEW
This chapter requires the LabVIEW Development Environment and installation of the ALIARO
LabVIEW drivers.
To identify hat the cards are correctly inserted and work properly with the right firmware,
LabVIEW provides basic VI scripts to check SLSC cards mounted in chassis:
1. Open LabVIEW and select “Help” in the top menu bar and press “Find Examples…”.
This opens a new window listing pre-made LabVIEW examples.
2. Switch to the “Search” tab and enter keyword “SLSC” and search.
3. In the new filtered table (to the right) find and select VI called “Configuration.vi”. This
VI can locates all cards that are online in a SLSC chassis.
4. To find the newly inserted cards look for the SLSC chassis IP-address (in the table to
the right).
5. Count the card(s) in the table and verify that all installed cards are being located by
the program (this can be 1 to 11 cards per SLSC chassis).
Maintenance
Power off all connected device before attempting any maintenance. After maintenance is
complete, ensure that the device is fully dry and installed correctly, before powering the system
back on.
Warning - Many components within the chassis are susceptible to static discharge
damage. Service the chassis only in a static-free environment. Observe standard
handling precautions for static-sensitive devices while servicing the chassis. Always
wear a grounded wrist strap or equivalent while servicing the chassis.
Clean dust from the chassis exterior and interior as needed, based on the operating
environment. Periodic cleaning increase’s reliability.
Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a soft-bristle brush
for cleaning around components
Calibration
Recommended warm-up time 30 min
Calibration interval Not required, recommended on system level
