10. Relay working modes
10.1. Normal open/ normal closed wiring options
The G022P 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 7: 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 G022P is
powered up. This is for fail safe systems where the power going off in the G022P will close relay 1 and activate
the output of relay 1.
Remember, the device processes one command at a time. Each command will have a reply to confirm the
command has been received and executed. You must wait for a reply message before sending another
command.
All SMS text commands must always be sent using CAPITAL letters. Do not add spaces or
any other characters.
10.2. 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 two relays also support two working
modes, self-lock and latching control.
