2 Product overview

The automatic transfer switch concept is applied to any application requiring switching from the

primary power line to secondary power line to ensure the supply of loads.

The OMD800 has two sensors to monitor two power lines; both sensors are able to work with single

phase or three-phase lines. This unit can be supplied with an external auxiliary power supply. Monitor-

ing, configuration and control are possible via Modbus RTU connection. The OMD800 has a graphic

display where the user is able to check the settings and get all the information about status of the

OMD800.

Analysing the voltage, frequency and the phase balance. Includes the generator START / STOP

command. Communication via Modbus.

2.1 Typical applications

A. Mains – Generator line

In case of loss of the primary power line, the OMD800 device manages the switching to the emergency

power line equipped with a genset system.

B. Mains a – Mains b

In case of loss of the primary power line, the OMD800 device manages the switching to a secondary

power line used as an emergency source.

Figure 2.3 Mains a – Mains b

Automatic control unit type OMD800 is designed for single and three-phase distribution systems in

diverse applications. OMD800 is supplied from Line 1 and Line 2 and can be used without external

power supply.

Figure 2.4 OMD800 have the capability to monitor two three-phase power lines, both able to work

with single phase, too.

OMD800 has an external auxiliary power supply possibility for guarantying an uninterrupted power

supply for the device in the case where the Line 1 and Line 2 are not available.

From the display, user can choose whether the N-line is connected or not.

3.1 OMD800 switching sequence

3.1.1 Line 1 priority

The switching sequence of OMD800 can be summarized in following steps:

An anomaly occurs on the Line 1

Switching delay

Generator start

Delay on transfer

If Pre-transfer signal active: Pre-trasnfer signal output on,

Pre-transfer I to II delay

Change-over switch (Switch I) to the position O

Dead band I to II delay

Change-over switch (Switch II) to the position II

If Pre-transfer signal active: Pre-transfer signal output off

And the back switching sequence can be summarized in the following steps:

The Line 1 will start the normal functioning

Back switching delay

If Pre-transfer signal active: Pre-transfer output on,

Pre-transfer II to I delay

Change-over switch (Switch II) to the position O

Dead band II to I delay

Change-over switch (Switch I) to the position I

If Pre-transfer signal active: Pre-transfer output o

Generator stop delay

Generator stop
