VA5 Pro vs. A4404 SAB
The VA5 Pro instrument, the A4404 SAB Signal Analyzer Box and the Virtual Unit application will be described
in this user manual. This chapter should clear up the difference between them.
VA5 Pro
VA5 Pro is a portable vibration analyzer which is based on unique Digital Signal Processing board (DSP)
developed by Adash.
A4404 SAB (Signal Analyzer Box)
A4404 SAB is a pocket size vibration analyzer which contains input connectors for sensors. It uses the same
DSP board as VA5 Pro but it doesn't contain keyboard and screen. It must be connected with computer via
USB. You need to install Virtual Unit application which is the same software used in VA5 Pro. Almost all
functions described in this manual work both in the instrument and in the Virtual Unit. You will be notified when
some difference occurs. Virtual Unit and A4404 SAB peculiarities will be described in a standalone chapter in
the end of the manual.

Before Switching On
General Warnings
Only suitable ICP powered sensors can be connected to the AC signal inputs.
If the measurement without ICP power is required, ICP power must be switched off. You can damage the
external signal source, which is not protected against ICP powering.
AC channels - voltage higher then 18 V (peak) can damage the instrument.
DC channels - voltage higher then 30 V (peak) can damage the instrument.
Always use only original cables designed for connection with sensor.
Long push and hold of POWER button evokes incorrect instrument switching off. Data could be lost.
If you are unsure, contact your distributor or the manufacturer.
Ignoring an
y recommendations mentioned below may cause failure of the device.
Operating with a power higher then 24 V can cause an accident.

Battery Charging
Charge the battery only at 0 - 40°C (30 - 100 °F)!
The POWER socket for external charger is on the top panel. The battery LED diode lights orange during
charging and lights green when fully charged.
The VA5 instrument uses Li-ION (LiON) batteries. This type of battery should not be discharged completely. If
the battery is discharged below certain Voltage, we call it deep discharging. The deep discharging shortens
battery life. The charging of deeply discharged battery takes much longer.
If the instrument is not charged for longer period of time, then the deep discharge can occur. It is caused by self-
discharging of the battery. Another cause of deep discharge can be a situation when the instrument is switched
to the SLEEP mode by the Power Off button (instead of switching off the instrument). When the battery is
deeply discharged, it takes much longer to charge it again. Sometimes the indicator on the charger does not
light when the battery is deeply discharged – it does not mean it is not charging. Please keep the battery
charging even if the indicator does not light, the indicator will start light later.
To avoid deep discharge of the instrument, charge it regularly, even when you don’t use it. We recommend you
to check if it is charged every 3 months.
WHAT TO DO WHEN YOU CANNOT SWITCH ON THE INSTRUMENT/ WHEN THE INSTRUMENT CANNOT
BE CHARGED NORMALLY:
- Discharged battery – battery needs to be charged (charging for approximately 5 hours), the instrument
can be switched on normally with the charger connected
- Deeply discharged battery, when the instrument wasn’t charged for longer period of time – the
instrument needs to be charged completely until the indicator on the charger starts light green. It can
take more than 12 hours. The indicator on the charged does not light from the beginning of charging
process. Sometimes it is not possible to switch on the instrument even with the charger connected.
- Damaged charger – when the charger is connected, the indicator should start to light (green or orange
color), only with deep discharge the indicator does not light immediately.
- Sudden decrease of battery life – the instrument needs to be charged and discharged completely few
times (usually 2-5 times). The battery lifetime should increase this way.
Switching on
The POWER button is in bottom left corner of the front panel. Press the button for a few seconds until a power
LED begins to light. Firstly it blinks orange for a while, then it lights blue. A keyboard backlight blinks for a while.
Switching off
Use a Power Off in main MENU and confirm.
Warning! The POWER button (intended for the switching on) doesn't turn the instrument off. It switches it into a
sleep mode!

16
Sleep Mode
Use the POWER button (described in the "Switch on" chapter) to switch the instrument into a sleep mode. The
screen is off and power consumption is lower in the sleep mode. Use the same POWER button to wake up
again.
Note! You can use any button to wake the instrument up. However notice the button press isn't ignored by the
system even in the sleep mode and the press can cause some unexpected event in the application. The
reaction to the button press is same like not being in the sleep mode.
Auto Switch off
If no button is pushed in 5 minutes from switching on, the instrument will be switched off.
Emergency Switch off
This is not correct method to switch off the instrument. Using it can cause data corruption. Use this method only
in case of emergency (eg. when the system freezes).
Push and hold the POWER button for about 10 seconds. Instrument will switch off.
Capacity Warning
If this warning message appears, you need to get free disc space by removing the measurements, routes or
records, which are not needed.
Connection to the computer
VA5_DISC
All data like projects, measurements, readings, setups and so on are stored to a high capacity hard disk which
is intended for internal purposes only. Furthermore the instrument contains the VA5_DISC, it is flash memory,
which is accessible from external computer. The VA5_DISC is an interface for data. For example, you save a
route from DDS to the VA5_DISC, the instrument copies it automatically to hard disk. Then you measure the
route and then you export the route back to the VA5_DISC. Here you can read it from computer. You don't need
to export all data from internal hard disk. Export only the data which you want to read from computer. A detailed
description how to export will be stated later in chapters about project's control for each module.
Connection
To make a connection between computer and instrument (more precisely VA5_DISC) use the USB cable which
is the standard accessory of VA5 set.
The connection to PC is indicated by icon located on the bottom right corner next to battery icon. For data
download you must be in the main screen.

17
Until you are not on main screen, the VA5_DISC remains to be connected to the instrument processor and you
cannot see it on your PC. The correct connection with PC is announced by the message box.
VAx_DISC
Sometimes you may need higher capacity interface disk than the VA5_DISC (16GB). You can connect any
external disk via USB. In order that the instrument is able to recognize your disk, you must name it as
VAx_DISC. Use a standard USB OTG cable (see bellow) to allow the instrument to act as a host. Connect the
small plug to the USB socket then connect the VAx_DISC to the OTG's socket. When VAx_DISC is connected
the instrument prefers it against VA5_DISC.
Note: The OTG cable is not a standard accessory of VA5 set.

Input Channels
All input sockets are in the top panel.
The input sockets IN1, IN2, IN3, IN4 are used for AC and DC signals. The TRIG input socket is used for trigger
signals, usually tacho. All sockets have several pins. It enables to connect more signals to one socket (see wire
diagrams).
The AC inputs enable to measure max voltage peak +/-12V. The DC channels enable to measure max +/-24V.
IN1 Socket
1 – GND
2 – +5V/0.1A
3 – DC1
4 – NC
5 – SHLD
6 – +20V/5mA
7 – GND
8 – AC1
Warning! Pin 2 of IN1 socket (ultrasound sensor powering) is internally connected with pin 2 of TRIG socket
(tacho sensor powering).
IN2 Socket
1 – GND
2 – AC4
3 – DC2
4 – AC3
5 – SHLD
6 – AC1
7 – GND
8 – AC2
Pay attention to possibility of connecting all four AC channels to IN2.

Standard Cable Wiring
The standard cable, which are the part of the VA5 set, have the sensor signal connected to the pin number 8.
The second sensor wire is connected to the ground (pin 7).
If you want to use the tri-axial sensor, then you have to use the IN2 socket (pins 6,8,4) + ground (pin 7). You
need the special cable for this purpose.
