*Recommended Cycle Time Settings
Output Type Recommended Setting (seconds)
B (5A/3A) 15 to 120
E (0-20 mA) 0.2
F (4-20 mA) MUST be set to 0.2
G (4-20 mA) MUST be set 0.2
S (pulsed 20 Vdc) 0.2
T (S.S. relay) 15 to 120**
Y (5A/3A) N.C. 15 to 120 (Output 2 only)
** “T” outputs directly driving non-inductive loads (small heaters) can have
cycle times as low as 0.2 seconds.
PID Output Type
Control Menu
As with the Output Menu, the Control Menu will change, depending
upon the Output Type selected.
Note: These parameters are auto-
matically set during the autotune procedure. We do not recommend
altering the value of these control parameters unless your process
requires manual tuning.
Setting Derivative
(Rate) or Integral
(Reset) to
disables that aspect
of PID control.
If BOTH outputs are
set to direct-acting or
BOTH outputs are set
to reverse-acting, then
only one proportional
band selection will be
displayed.
Display Parameter Selection
Proportional Band 1 1...to span of sensor
Proportional Band 2 1...to span of sensor
Derivative Action (Rate) 0 to 2400 seconds
Manual Reset OFF, -100% to 100%
NOTE: The Integral Action (Auto Reset) parameter appears only if OFF
is selected in the Manual Reset parameter.
Integral Action (Auto Reset) 0 to 9600 seconds
