h) Relay Screen
This screen allows you to set the trip point for when the relay switches. The relay also contains
some hysteresis to stop it ‘chattering’. This is configurable from this screen as well and is
represented as a percentage of full scale of the input channel, with limits of 0.0% (i.e. no
hysteresis) to 10.0%. If the second relay option is factory fitted then the above fields are
duplicated for the second relay and are changed to Trip 1, Hyst 1 & Trip 2, Hyst 2 as
appropriate.
