t P
Time Proportioning Cycle Time. Select
1 t P
to
8 0 t P
.
1 t P
A setting of
1 t P
is recommended for solid state outputs (SSR or
15 VDC).
2 t P
to
8 0 t P
Time Proportioning Control is adjustable in 1 second
steps. Recommended for mechanical outputs (relays,
solenoids, etc.). For best contact life, a time should be selected
as long as possible without causing the process to wander.
#
P u L
Pulsed Time Proportioning Output: Select
1 P u L
to
7 P u L
.
1 P u L
=
Linear and
7 P u L
= most nonlinear. Changes output linearity for
use in cooling applications or for extremely fast response
processes. At the center of the proportional band, a pulse value
of 1 provides an output of one second on and one second off
(50% output). A pulse value of 2 provides an output of one
second on and two seconds off (33% output). Output at center
of band equals one second on, 2
(pulse value-1)
seconds off.
P r o P
For Current (Code 5) outputs only.
The following menu items apply only if your control is equipped with a second set
point (last digit of model number is not zero). If your control does not have a second
set point, jump to the
t u n E
menu on the next page.

Output selection: Select
O n O F
, #
t P
, #
P u L
, or
ProP
.
O n O F
A setting of
O n O F
allows the control to operate in simple on/off mode.
This setting forces the control to turn off at set point, and on at the set
point plus the differential (
S P 2 d
). When selected, the
O u t 2 / O n O F
menu
item is followed by ####
S P 2 d
, and the
P b 2
selection in the Secondary
menu and the
S 2 O L
and
S 2 O H
selections in the Secure menu are
suppressed.
S P 2 d
Set Point On-Off Differential (hysteresis). Select
1
to
9999
(direct
acting), or -
1
to -
9999
(reverse acting). See
S P 1 d
on the previous
page.
