5.6 Programming Setpoints for Inputs (Rules)
There are some rules to follow when particular Inputs are pro-
grammed.
1. In the setpoints, Time Delay Neutral (TDN) must be set to
"n/a" when using "Load Decay." Conversely, "Load Decay"
must be set to "n/a" if "TDN" is being used.
2. The voltage unbalance protection can be disabled by the user
simply by setting them to "0".
3. With the Input of the controller programmed to the following
inputs, associated setpoints will also be required to be appro-
priately set.
