To protect equipment that may be controlled by Recorder Out, the default condition for Recorder Out when
returning from power up is always OFF unless specifically set otherwise, this includes power up in Unattended
Operation. To enable Recorder Out for use while the sensor is operating in Unattended Operation mode, a special
function must be set. This parameter, UOP Recorder Out State, is circled at left in Figure 3. When set to True,
Recorder Out will function while the sensor is running in Unattended Mode. The parameter can only be changed
when the sensor is operating in Average mode (Figure 3 middle, Mode). While the sensor is in UOP Active mode (In
progress) the function will remain set and the sensor can be repeatedly power cycled without losing the Recorder
Out settings or UOP state. If the sensor is powered up while UOP is not active, UOP Recorder Out State will be
cleared to FALSE and Recorder Out will not operate in Unattended Operation unless the parameter is set again.
Unattended Recorder Out Example
To enable Recorder Out while in Unattended Operation, perform the following.
1. Set the sensor to Preset Average and set your Frequency
2. Set Recorder Out Upper and Lower Limits (See Recorder Out section for info)
3. In the Sensor Window, Under the Mode Dropdown, Set the mode to Recorder Out (Figure 3 middle)
4. Verify Recorder Out functionality
5. Under the Mode Dropdown, Set the mode back to Average (Figure 3 middle)
6. Under Basic Unattended Operation, set UOP Recorder Out State to True (Figure 3 left)
7. In the Sensor Window, Under the Mode Dropdown, Set the mode to UOP (Figure 3 middle)
8. In the Sensor Window, Click Start UOP
9. In the Sensor Window select Do Not Save Data or if Option UOP is installed, data can be stored.
10. Remove and Reconnect power and test to verify
11. To return the sensor to normal operation, connect to the computer, select Halt UOP, (which appeared in
the menu when UOP was started); then set Mode to Normal set UOP Recorder Out State to False.
