RATE—Rate action affects the recorder’s output
whenever the deviation between setpoint and process
variable is changing. It affects it more when the deviation
is changing faster. (This is the “derivative” component of
control.)

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, RATE T is used for
heat control. Cooling control would use RATE2T
described later in this table.

Reset adjusts the recorder’s output taking into
consideration both the size of the deviation (SP-PV) and
the duration of the deviation. (This is the “integral”
component of control.) The amount of corrective action
depends on the value of PB or GAIN.

The reset value specified here determines how many
times proportional action is repeated per minute
(I RPM) or the length (in minutes) of the reset action (I
MIN). For example, if I MIN = .5, it is the same as if I
RPM = 2. The result is the same; two resets are
performed in every minute.

MANRST
–100 to +100 (in % output)
[factory setting = 0]
[factory setting = 0]
MANUAL RESET—This parameter is only applicable if
control group parameter “CTRALG” is “PDMR”
(PD with manual reset). Because a proportional recorder
will not necessarily line out at setpoint, there will be a
deviation (offset) from setpoint. This reset value can be
used to eliminate the offset and lets the PV line out at
setpoint. The controller output is the computed output
plus the value of MANRST.
