P108 Far Blanking Distance 
This  is  the  distance  (as  a  percentage  of  empty  level  P105)  beyond  the 
empty point that the unit will be able to measure, and by default is pre-set to 
20% of the empty level.  
If the surface being monitored can extend beyond the Empty Level (P105) 
then the far blanking distance can be increased to a maximum of 100% of 
empty level. 
This parameter is always entered as a % of empty level. 
 
 
Relay Parameters 
All relay related parameters are prefixed with a 2**. 
The  second  digit  of  the  three-figure  parameter  number  denotes  the  relay 
number as follows: 
21* parameters for Relay 1  
22* parameters for Relay 2 
23* parameters for Relay 3 
The third digit selects specific parameter for the setting of the relays, which 
can be selected individually and results in the following parameter numbers 
for each relay. 
Relay 1   210 to 219 
Relay 2   220 to 229 
Relay 3   230 to 239
