(totalizer, totalizer with relays, or batcher) and the functions necessary for the particu-
lar application (reset, unlatch, start, etc.), determine the function(s) of each control
input and select an input device appropriate to the function.

1
An RC surge suppressor is recommended across all inductive loads.
2
The transistor is optically isolated and may be connected as a sink (shown), or
a source by wiring the load between terminal 5 and - (minus).
3
A reverse-biased diode (1N 4001 or equiv.) is recommended across all
inductive loads.
