Common Parameters 
 
P216, P226, P236, P246, P256 - Relay Allocation 
This parameter determines which input the relay will act on. You can set it 
to the transducer (default),  or the optional auxiliary (current) input,  or an 
average of the two. In most cases, this will not need to be changed from the 
default.  
Relay acts on Xducer 1calculated levels. 
Relay acts on Xducer 2 calculated levels. 
Relay acts on optional current input levels 
When Ultra Wizard = 1 Level/Volume or 2 Pump/Differential  
Relay acts on the resulting average levels 
of two signal inputs. 
When Ultra Wizard = 2 Pump/Differential  
5 = Differential of 1 & 2 
Relay  acts  on  the  resulting  differential 
level of two signal inputs. 
 
P217, P227, P 237, P247, P257 - Relay Closures 
The Ultra 5 will record how many times each relay is closed, this parameter 
displays the number of times the relay has activated since the relay has been 
in use. It can be reset with any value. 
P218, P228, P238, P248, P258 - Relay Fail Safe 
Your Ultra 5 has a general fail-safe parameter P808. However, this can be 
overridden so that each individual relay has its own independent fail safe 
mode.  
This parameter determines what the relay will do in the event of the Failsafe 
Time (P809) expiring.  
Relay assumes system default mode P808 
Relay remains in its current state
