6 Proportional Band1
(PB1) P. Band 1 Defines portion
of input span
in which the
Output 1 power
level is proportional to
the (offset) process
variable value 0.0% (ON/
OFF control)
to 999.9%
of input span.
Default
10.0%
7 Proportional Band 2
(PB2)
2
P. Band2 Defines portion of
input span in which the
Output 2 power level is
proportional to the
(offset) process
variable value 0.0% (ON/
OFF control)
to 999.9%
of input span.
Default
10.0%

Spread Defines the portion of
the proportional band
(PB1 + PB2) over
which both outputs are
active (overlap) or
neither output is active
(deadband) -20% to +20%
(negative value =
deadband, positive
value = overlap)
Default = 0%

only)
-100% to +100%
(Output 1 & Output 2)
Default = 25%
