P*210, P*220, P*230, P*240, P*250, P*260 - Relay Type 
This parameter defines what type each relay should be, see the table below 
for  available  options,  which  will  be  dependent  on  the  Operational  Mode 
(P100), selected. 
Relay  not  in  use  or  programmed  and  LED 
will always be off. 
Relay  is  programmed  as  an  alarm  relay, 
which  will  de-energise  ON,  and  energise 
OFF. This will ensure an alarm is raised if 
the power fails to the unit. 
Relay is programmed as a pump relay, which 
will energise ON, and de-energise OFF. 
Relay  is  programmed  as  a  control  relay, 
which  will  energise  ON,  and  de-energise 
OFF. 
Relay  is  programmed  as  a  miscellaneous 
relay,  which  will  energise  ON,  and  de-
energise OFF. 
 
Alarms 
P1 and P2 
When P*210, 220, 230, 240, 250, 260 =1 (Alarm) 
The second parameter for each relay determines the function of the alarm.  
P*211, P*221, P*231, P*241, P*251, P*261 - Relay Function 
This parameter defines what function the alarm will respond to as follows. 
Alarm is based on the level in the vessel, and the 
type of level alarm (P*212, 222, 232, 242, 252, 
262) and two setpoints must be set (P*213, 223, 
233, 243, 253, 263 & P*214, 224, 234, 244, 254, 
264). Setpoints are entered in Display Units or % 
of span as referenced to Empty Level.
