# # 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.
O u t 2 Output selection: Select O n O F , #tP , #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 (SP 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.
# # 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 t o 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.
