V-DOG2 3
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.
