##tP
Time Proportioning Cycle Time. Select
1tP
to
80tP
.
1tP
A setting of
1tP
is recommended for solid state outputs (SSR or 15VDC).
2tP to 80tP
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.
#PuL
Pulsed Time Proportioning Output: Select
1PuL
to
7PuL
.
1PuL
= Linear and
7PuL
= most nonlinear. Changes output
linearity for use in cooling applications or for an 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.
ProP
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 and Alarm Programming code is zero). If your control does
not have a second set point or if the second output is programmed as Alarm, jump to the"tunE"
menu on the following pages.
Out2
Output selection: Select
OnOf
,
2tP
,
2PuL
, or
ProP
.
ONOF
A setting of
ONOF
allows the control to operate as a simple on/off mode. This
setting forces the control to turn off at set point, and on at the set point plus the dif
ferential (
SP2d
). When selected, the
Out2/OnOF
menu item is followed by
####/SP2d
, and the
Pb2
selection in the Secondary menu and the
S2OL
and
S2OH
selections in the Secure menu are suppressed.
SP2d
Set Point On-Off Differential (hysteresis). Select
1
to
9999
(direct acting), or
-1
to
-9999
(reverse acting). This value will be neg
ative for reverse acting set points, and positive for direct acting
outputs. Set the value for the amount of difference between the turn
off point set point) and the turn on point. The drawing on the
previous page (See
SP1d
) shows output behavior for reverse and
direct acting.
