Nor-Cal SDC15 Controller - Manual (Page 106)

■ Polarity of output assign
The polarity of four output assigns (A, B, C, D) used for the output bit function
can be set.
• When the object control output is the relay output or voltage pulse output, and
the operation type of the DO Assignment is set for output bit functions 1 to 4, the
display and setting can be made.
• When the object event output is provided and the operation type of the DO
Assignment is set for output bit functions 1 to 4, the display and setting can be
made.
Handling Precautions
The output relay may be turned ON and OFF repeatedly at a high-
speed depending on the conditions.
To avoid such faulty operation, always strictly observe the following
cautions:
Control output 1: When any of [Output assign A, B, C, D] (ot1.2 to
ot1.5) is set at [49: Control output 1 status], do not set [1: Reverse]
for the same symbol of [Output assign A, B, C, D Polarity].
Event output 1: When any of [Output assign A, B, C, D] (ev1.2 to
ot1.5) is set at [48: Event output 1 status], do not set [1: Reverse] for
the same symbol of [Output assign A, B, C, D Polarity].
