Operation
Fill timer (INTERVAL)
Note
The INTERVAL function is disabled when the INTERVAL setting is
“0.0”. Adjusting the INTERVAL setting to “0.0” will also terminate
any in-progress functions of the INTERVAL timer.
The INTERVAL setting can be adjusted by placing the control mode rotary
switch in the INTERVAL position and using the RAISE/LOWER toggle
switch to adjust the setting up or down. The display will move slowly at
first and then faster. Once near the desired value which is displayed in
minutes, simply release the switch momentarily and then resume
changing the setpoint at the slower speed. The instrument is shipped from
the factory with a zero interval time.
4.1.7 Select the appropriate units display option
Place the units mode toggle switch in the position desired for the display
output units during operation. The % position displays the percentage of
active sensor length that is immersed in liquid.
4.1.8 Connect the optional analog output signal
If the instrument was purchased with an analog output option, the
auxiliary connector J2 on the rear of the instrument provides a 0-10 VDC
or 4-20 mA analog signal corresponding to 0-100% of liquid level. Refer to
the Appendix for the pinout diagram of connector J2.
