COMMS parameter is displayed.  Press up 

 

 

 

6.4 

Alarm Option 

When an alarm board is fitted with free contacts for customer use, the contacts are taken to 
a panel plug on the control panel, wired as indicated: 
 

 

 
 
 
 
 
 
 
 
 
 
The purpose of the 2 amp fuse is to protect the internal circuitry from excess electrical 
current.   
The instrument configuration, and parameters available to the operator, depend on the 
customer requirements. 

6.5 

Remote Input and Output (Analogue Communications) 

When analogue communications are fitted, the contacts are taken to “banana plug” sockets 
on the control panel. 
 
 
 
 
 
 
Controller configuration depends on customer requirements.  
Remote input (when specified) may be switched on and off using the Remote setpoint 
enable parameter in the controller level 2, if this was made available for a particular 
application. In level 2 press page 

 

until ‘REM SP Enable’ is displayed,  press up 

 or down 



to select SP1 (the normal controller setpoint) or SP2 (the remote input setpoint), ‘SPX’ will 

appear in the top left corner of the display. 
Remote output does not require switching on and off. 

6.6 

Program segment output 

When the customer requirement is for program segment output, an extra parameter is 
revealed in the PROG list. For each program segment, after the segment type and settings, 
the parameter EVENT OUTS appears. This has values   

on

 and   

off

. If the value is set to 

on

, then the relay closes during the segment and a small 1 appears in the top left of the 

screen. 
If more than one program segment output is fitted, then there are extra boxes depending on 
how many event outputs there are.
