TPSC = Three Position Step Control

N/A = Not Available – This output algorithm type cannot be performed with this Output 1/2

option.

INU = Installed, Not Used – The installed Output 1/2 option is not used for the configured

output algorithm type.

Not Needed = Auxiliary Output is Not Needed to provide the desired output algorithm and can

be used for another purpose. With the proper configuration, Auxiliary Output
could also be used as a substitute for the Current Output

* To obtain this output algorithm type with these Output 1/2 Options: 1) Configure the

OUTALG selection as “TIME D”; 2) Configure Auxiliary Output for “OUTPUT” and; 3)
Scale the Auxiliary Output as necessary for the desired output algorithm type. For these
