Time/Current Output 2 N/I Output 1 Alarm 1 Not Needed
N/I = Not Installed
N/A = The output form or the individual output is Not A
vailable or is not used for this output form.
Not Needed =Auxiliary Output is not needed to provide the desired output function and can be used for
another purpose. Auxiliary Output could also be used as a substitute for current Output 1.
