0.0 to 250.0 seconds
The Cycle Time is entered in seconds with one tenth of a second
resolution. It is the total time for one on and one off period of an OP1
time proportioning control output. With time proportional control, the
percentage of power is converted into an output on-time relative to the
cycle time value set. (If the controller calculates that 65% power is
required and a cycle time of 10.0 seconds is set, the output will be on for
6.5 seconds and off for 3.5 seconds.) For best control, a cycle time equal
to one-tenth or less, of the natural period of oscillation of the process is
recommended. When OP1 is an analog output, the Cycle Time is the
analog output update time. A Cycle Time selection of 0.0 will disable the
output.
r = Reverse Acting
d = Direct Acting
A = Alarm 3
This determines the action for each Output. When programmed as
r1d2, Output 1 will function in the Reverse mode (heating) and Output 2
will function in the Direct mode (Cooling). When selected as A, OP2 is
configured as the alarm 3 output and the alarm 3 settings will become
accessible in the Alarm module configuration menu and OP2 parameters
will no longer be available.
0.0 to 100.0 %
This parameter may be used to limit controller power at the lower end
due to process disturbances or setpoint changes. Enter the safe output
1 power limit for the process. When the controller is in r or OnOF Control
Mode or Auto Tune, this limit does not apply.
0.0 to 100.0 %
This parameter may be used to limit controller power at the upper end
due to process disturbances or setpoint changes. Enter the safe output
1 power limit for the process. When the controller is in r or OnOF Control
Mode, this limit does not apply.
This parameter sets the power level in the event of an input failure
(open TC/RTD or shorted RTD). Manual (r) Control overrides the
input fail preset.
