9. Relay working modes
9.1. Normal open/ normal closed wiring options
The G033 is equipped with three digital output relays for connection to equipment to be controlled. The relays can be
set up in normal open and normal closed positions. This gives the customer the advantage of having it set as a
failsafe if there is a power loss or for timing the relay to open or close with delays.
Figure 6 Relay positions
Normal open position
– if common and normal open are wired then relay 1 will be off when powered up. To
activate relay 1 either a message or a command must be received from the user or from input 1. This activates
the relay and closes the circuit turning on the output of relay1.
Normal closed position
– if common and normal closed are wired then relay 1 will be active while the G033 is
powered up. This is for fail safe systems where the power going off in the G033 will close relay 1 and activate the
output of relay 1.
It is important to understand that relays wired in ‘normal closed’ position will operate in the opposite way to
‘Normal open’. For example the command to turn the ‘Normal closed’ relay setup OFF will turn the relay ON.
This needs to be taken into account when setting up your designing system.
9.2. Daily timer setting
Daily timer settings are for Relays 1 and 2. They support a daily timer function to control the actions of the output.
This is useful for turning the relays on and off without having to message the device.
The relays will switch to ON/OFF states according to the timer settings.
These relays also support two working modes, self-lock and latching control.
