SECTION 1 : INTRODUCTION
1.1 Preliminary Comments & Safety Precautions
This manual covers installation, operation and
maintenance of the V-DOG2 AC Voltage & Frequency
Detector to assist the user in operating the V-DOG2.
This manual is for use by authorized and qualified
personnel only.
WARNING
High voltage will cause severe injury or death
1.2 Product Overview
The V-DOG2 control module is a programmable,
multi-function voltage and frequency detector. With
compact size it has the benefit that it can be installed
on the door of a panel and replace traditional relays.
It’s main functions are as follows：
●Programmable through control panel
●Compact size with user-friendly 7-segment display
●User selected cycle-mode or fix-mode displays for
3-phase and single-phase voltages and frequency
●Monitors AC power source for over or under voltage
●Monitors AC power source over or under frequency
●User and Factory set parameters are permanently
saved and will not be lost due to power failure
●Control panel displays power status and fault alarms
1.2.1 Operational Simplicity
From installation to programming and usage, the
V-DOG2 controller is designed with operational
simplicity in mind. The user-friendly front panel
interface simplifies routine operation, programming and
setting.
1.3 Specifications
The wide range of parameter settings in the V-DOG2
control module can supply all the requirements of a
power system. These features can be set through a
user-friendly operating panel interface. All user and
factory settings are permanently saved and will not be
lost due to power failure.
Feature 1：Full phase Over voltage/Under voltage /
Lost phase sensing
The V-DOG2 control module can detect each phase
voltage in the power supply. Users can set their own
over-voltage and under-voltage ranges. (Refer to
setting items 1, 2, 3 & 4 in Table 3.4)
Over Voltage Setting range：110 530 Vac
Over Voltage reset value：-5Vac (not adjustable)
Under Voltage Setting range：80 470 Vac
Under Voltage reset value：+5 Vac (not adjustable)
Feature 2 ：Over Frequency/Under Frequency
Sensing
The controller is able to detect the frequency of the
power supply. Users can set their own over frequency
and under frequency ranges. (Refer to setting items 5,
6 & 7 in Table 3.4)
Over Frequency setting range：51 75 Hz
Over Frequency reset value：1 Hz (not adjustable)
Under Frequency setting range：40 59 Hz
Under Frequency setting value：-1 Hz (not adjustable)
Feature 3：Control Panel Lighting Test
The Control Panel Lighting test provides users with a
convenient view of whether the panel LED indicators
are normal. Press the Setting button on the control
panel and all displays will light at the same time.
SECTION 2 : OPERATOR PANEL
2.1 Overview
This section introduces the hardware architecture and
features of the V-DOG2. The contents are divided into
the following sections :
●Display screen
●Function buttons
●Panel LEDs
2.2 Display screen
The V-DOG2 controller has a four-digit, seven-segment
display for all parameters, setting and messages.
The screen displays：
●Full phase voltage / frequency
●Program setting parameter

2.3 Function Buttons
The front panel uses three membrane switch buttons.
2.3.1 Increase (▲) Button
In normal mode pressing the Increase (▲) button
changes the display to the next phase voltage reading.
When entering system parameters in setting mode
each press of the up (▲) button increases the
displayed parameter by a single unit. If held down the
Increase (▲) button continues to scroll rapidly.
2.3.2 Decrease (▼) Button
In normal mode pressing the Decrease (▼) button
changes the display between voltage, duty time and
frequency.
When entering system parameters in setting mode
every press of the Decrease (▼) button decreases the
displayed parameter by a single unit. If held down the
Decrease (▼) button the displayed parameter will
continue to scroll rapidly.
2.3.3 Setting button - between (▲) & (▼)
When the Setting button is pressed the V-DOG2 will
enter the setting mode and the control LED indicators
will flash for several seconds. In this mode all controller
functions of V-DOG2 will be temporarily halted.
2.4 Panel LED indicators
The red LEDs on the control panel indicate different
power failure conditions. Refer to the following
illustrations for details.

SECTION 3 : OPERATION
3.1 Overview
This section will introduce the operation mode and user
functions of the V-DOG2 control module. It is divided
into two main parts :
● Programming settings mode
● AC voltage correction
This section contains all actual operating and use
situations. The user should first read the previous
sections before reading this section.
3.2 Programming Settings
In the Program Settings mode all parameters can be
set directly on the V-DOG2 operator panel. To enter
the system Program Setting mode hold down the
Setting button for 4 seconds. The “Vr. 01.01”will
appear on the display for 2 seconds displaying the
current version of the program.
Press the Setting button to skip to the next line in the
System Settings Table 3.4 below. Use the increase
button (▲) and the decrease button (▼) to set the
value of each parameter for each step. If you press the
increase button (▲) or decrease button (▼) the
parameter value will increase or decrease by 1. If you
hold down the increase button (▲) or decrease button
(▼) the parameter value will increase or decrease until
the built-in limit is reached.

Press the Setting button to jump to the next line until
“END”is displayed and end the program setting mode.
Or press and hold the Setting button for 4 seconds can
also directly end the program setting mode.
If an error appears during the settings process or you
want to return to factory settings you only need to press
the Increase button (▲), Setting button and Decrease
button (▼) at the same time. Press for 4 seconds until
the letters “Au.Po”appear on the display screen.
Confirm that all settings have been reset to the factory
settings. (For factory setting values refer to System
Settings Table 3.4).
3.3 Voltage Calibration
The voltage value of the V-DOG2 controller is
accurately calibrated at the factory. However, if the
voltage value needs to be modified perform voltage
calibration according to the following procedure.
Step 1：Before carrying out voltage calibration confirm
that the AC power is properly connected.
Step 2：Enter the program setting mode and set item 9
to (01). Then press the Setting button and the word
“VAdJ”appears in the display.
Step 3：Press the Setting button to select the phase
you want to recalibrate.
Step 4：Use a precision multimeter to measure the
voltage value of the phase you want to calibrate.
Step 5：Press the increase button ( ▲) and the
decrease button (▼) to enter the voltage reading from
the meter.
Step 6：It is necessary to press the Setting button to
change to the next phase to be calibrated or until “End”
appears on the screen. To end the program
immediately press and hold the Setting button for 4
seconds to exit the program.
Step 7：If the display shows (FAIL) it means that the
calibration has failed. Press the Setting button to clear
the alarm message and start the operation again
according to step 1.
