Manual Operation of Proportional Outputs 4.9

To enter the Manual mode, press and release the AUTO/MANUAL key. If the Standby mode
is on in the Enable mode the instrument will enter the Manual mode. The Manual mode
status LED will light to indicate that the Manual mode is in use. Shifting from the Control to
the Manual mode is bumpless. The proportional output(s) will stay at the last value(s)
calculated by the control algorithm. The upper display will show the current process value. If
Output 1 is a proportional output, the lower display will show the Output 1 percentage of
output value and the PO1 status lamp will light. If PO1 is not a proportional output, the lower
display will show the Output 2 percentage of output and the PO2 status lamp will light. If dual
proportional outputs have been selected, press the SCROLL key to toggle the lower display
between the PO1 and the PO2 values. To change the percentage of output value, press the
SCROLL key to display the percentage output value that you desire to adjust. Use the UP or
DOWN key to change the percentage value as desired.
To exit the Manual mode of operation press the AUTO/MANUAL key once more. The Manual
mode status LED will go out. The Auto Transfer to the Control mode function can be selected
in the Program mode to shift the instrument from Manual to Control mode automatically when
the process variable reaches setpoint.
The proportional control output value(s) may change rapidly when returning to the Control
mode. The output change will depend upon the Tune mode selections and the process value
deviation from setpoint at the time of transfer.

Automatic Transfer Function 4.10

Automatic transfer provides automatic shifting from the Manual mode to the Control mode of
operation when the process value reaches setpoint. This feature is selectable in the Program
mode.
