Introduction

Outlets switching for all units can do in a "System tree" of the Web Interface.

To switch on/off all relays for all units go to the "Main menu" "" >> "System Tree">> Choose a "Relay" element you want to configure and click on it >> A modal window with properties will pop up:

1	Name	Relay-# by default. Can be changed.
2	Group	A group can be selected for visual display in the "Group tree" menu
3	Hardware port	Port 1 = relay 1/outlet 1; port 2 = relay 2/outlet 2 and so on.
4	Current state	Shows current state of the relay
5	Current value	"0" - off "1" - on
6	Initial state	"off" - when the system starts, the relay will be switched off. "on" - when the system starts, the relay will be switched on.
7	New state	"do not change" - no impulse applied "pulse" - switches the relay into the opposite state for a period of time specified in the "pulse duration" field
8	Pulse duration	Measured in seconds. 1-second minimum.

Example: The relay is "Off". Let's say we need to switch it "On" for 30 seconds. In the field "New state" choose "Pulse"; specify "Pulse duration" for 30 sec. Then press "Apply" or "Save". The relay will switch to the "On" state for 30 seconds. Then it will return to the "Off" state.

Outlets switching

To start managing relay switching of VT604 or VT608 units, go to "Main menu" "" >> "Outlets" menu. You should see the outlets:

First, choose which outlets you need to switch to "On" or "Off" state, then press "Apply". The interface window will update itself in a moment:

For the picture above, we've switched "On" Relay-1 (Outlet-1) and Relay-3 (Outlet-2). They are highlighted in green color. Outlet-2 and Outlet-4 are currently off.

It is possible to manage each outlet individually. For that go to " " >> "Group tree" or "System tree" menu >> click on any of the four relays.

The "Pulse" parameter always changes relay's state to an opposite state.
