Select a Setpoint OFF pressure value. If the sensor pressure rises
above this value, the rear panel output de-activates (voltage high)
and the Setpoint # clears from the Main screen. The OFF reading
must be a higher pressure than the ON reading or an error (ERR)
warning appears in the rightmost column. Once valid settings are
entered, ERR changes to AUTO.
If a delay is required between the time the sensor detects the
Setpoint OFF pressure value and the output, de-activates (rear
panel, Main screen indicator and serial communication), select a
delay time in seconds. Example: A setting of 1.2 results in a delay
of approximately 1.2 seconds.
Options include:
❑
AUTO indicates the setpoint state is determined by
comparing the pressure to the setpoint limits. This is the
default setting and is used to enable the setpoint.
❑
OFF and ON are override values, which can also be used for
manual testing. Selecting OFF or ON does not clear
pressure/time settings.
