8.1   Remote Alarms

There are two seperate remote alarms for Pressure & Purity and a No volt / dryer control contact(see fig.1) 
 
A1 Terminal :  input (0-24v DC). 
A1 Terminal :   output (0-24v DC) common alarm output for pressure & purity. 
 
A2 Terminal :   input (0-24v DC).
A2 Terminal :   output (0-24v DC) for dryer control only.

8.2   Remote Stop/Start

•  To set up the remote stop start function, remove the link marked as ‘RS’ (remote start fig.1) between the 

live terminal and the PLC (see fig.1). A zero volt switch from the remote control needs to be installed in it’s 
place (see fig.2). 

•  When the connection is made you can start the generator using the HMI screen, the generator will 

operate normally. If the connection is broken, i.e. the generator has been remotely switched off, the 
generator will commence shut down procedure, stop cycling and go into standby mode this can also be 
achieved by using the shutdown feature on the HMI screen, displaying “STANDBY” on the display once 
completed.  

•  Using remote stop / start ensures the correct shut-down sequence is implemented.

8.3   Start Up Procedure

•  Ensure that all isolation valves are fully closed before operating. 

•  Hold down the Start/stop button located on the HMI Screen, this will start the generator. 

•  Slowly open the air inlet valve (page 11/12) and check for any leaks. Continue to open the air inlet valve 

until fully open. 

•  Allow the generator to cycle at least two times. 

•  Slowly open the ‘To buffer tank’ isolation valve (page 10/11) until the buffer tank is at full pressure        

(this will take a few cycles) 

•  Slowly open the ‘From buffer tank’ isolation valve (page 10/11). At this point the generator control system 

will be able to operate fully.

Beware, it can take up to two hours to clean the buffer tank.
