Common Parameters 
P2n7– Relay Closures 
The Ultra 4 will record how many times each relay has operated, 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. 
P2n8 – Relay Fail Safe 
The Ultra 4 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 set in P808 
Relay remains in its current state 
 
Data Log parameters 
The data log parameters contain the following information: 
Data Log Setup 
The data logged on to the SD card will depend on the system type currently 
in use, at an interval rate which is set in P129 Sample Interval. 
P129 Sample Interval  
This parameter sets the logging interval a log is sampled from the unit (in 
minutes) and stored on to the SD card.  Default = 5 minutes
