nitrogen gas generator

.8 remote start/stop control
To use the remote start/stop feature, open the enclosure and locate the wire link marked as ‘RS’ on the PLC (see item
No.1 for reference). Remove the wire link from terminal i0 and move it across to redundant terminal i6 (see item No. 2 for
reference).
In order to control the generator remotely via the start/stop feature you are required to install an additional two connections.
First, an additional wire connection is required into the terminal ‘24V DC output’ (see item No.3 for reference) this must be
wired externally to the input of a switch or relay. Once this connection has been made you will need to add an additional
connection on the output of the switch or relay, this should then be wired back to the PLC into terminal i0 (see item No.4 for
reference).
When the connection is made and the circuit is complete you can then start the generator using the HMI power ON button.
If for any reason this wired connection is broken, i.e. the generator has been remotely switched off, the generator will
automatically commence a shut down procedure, stop cycling and go into standby mode until the connection is reestablished.
Under no circumstances should an external voltage or current be applied to any of these terminals, as damage
to the control system will occur, negating the warranty.
