6.8.3 Simulation of analog outputs via MANUAL mode
Release and activation
✱
Select activation of simulation of the actual value output:
ADMINISTR. LEVEL/PARAMETER LEVEL/ANALOG OUTPUTS/
ANALOG OUTPUT 1 (2, 3)/SIMULATION/ON.
With "On" the output takes on the value of the "Simulation value" parameter.
When the device is in display mode, the word MANUAL appears in the status
line of the display.
Deactivation
✱
ADMINISTR. LEVEL/PARAMETER LEVEL/ANALOG OUTPUTS/
ANALOG OUTPUT 1 (2, 3)/SIMULATION/OFF.
The corresponding output of the device works again.
When the device is in display mode, the word MANUAL disappears from the
status line of the display.
6.9 HOLD mode
In HOLD status the outputs take on the states programmed in the relevant
parameter (controller channel, switching output or analog output).
This function can be used to "freeze" switching outputs and the analog
outputs of the device. This means the current status of the output will be
retained even when the measured value changes. Control is not via the device.
HOLD mode can be activated by pressing the key or by the binary input.
Activation by pressing key
✱
Press and hold the and keys longer than 3 seconds.
Then the outputs of the device respond according to the default settings.
The word HOLD appears in the status line of the display.
If MANUAL mode is activated while HOLD mode is activated, MANUAL mode
takes precedence and MANUAL then appears in the status line of the display!
MANUAL mode can be terminated by pressing the
key.
If HOLD mode is still activated (by the binary input or by keyboard), the device
then returns to HOLD mode!
EXIT
EXIT
If the and keys are pressed for less than 3 seconds, the device goes
into Manual mode.
Then the outputs of the device respond according to the default settings.
