PB
or
GAIN
0.1 % to 999.9 %
or
0.1 to 999.9
[factory setting = 1.0]
PROPORTIONAL BAND or GAIN—Which of these
prompts is displayed depends on the selection made for
control group parameter “PBorGN” (proportional band or
gain). Both proportional band and gain are ways of
expressing the proportional component of control. See
the description of control group parameter “PBorGN” for
details concerning the two terms.
ATTENTION
If control group parameter “OUTALG”
is “RLYD” (relay duplex), “Tcur” (time/current duplex), or
“CurT” (current/time duplex), and you are using the
recorder in a heat/cool application, PB or GAIN is used
for heat control. Cooling control would use PB2 or GAIN
2 described later in this table.
