Manufacturer’s Suggested
Annual Maintenance Protocol
For
High Level Alarm testing using
transducers without a test port*
For the Solar Gauge by Greenleaf Gauge
The EFG-8000 series of liquid level gauges operate as a very simple gauging devise
with level alarm options that require almost no maintenance. Measuring the current liquid
level in the tank and comparing the gauge reading to the charted amount can confirm
normal gauge accuracy. The comparison between the gauge readout and the charted
amount should differ no more than 2%.
The High and Low liquid level alarms are user set points in the gauge programming
as a percent of the total tank capacity. Access to these alarm values may be reviewed by
stepping through the setup program as detailed in the owners' manual*. The Low-level
alarm may be set to "off" at a zero value or any value 5% under the High-level alarm
value. The High-level alarm cannot be turned off and may not exceed 95% of tank
capacity. We strongly recommend against setting the High-level alarm any higher than
90% in normal conditions.
Although , High Level alarms may be observed this is not the preferred method
during filling as the liquid level reaches the set percentage of fill. The preferred method of
a High level alarm activation, provided the tank level is above 50%, is to go into the setup
program and adjust the High level alarm to just below the actual displayed level. This will
trigger a High-level alarm. The last option is to temporarily unscrew the transducer** just
up off the mounting nipple on top of the tank and very gently and slowly pull up on the
beaded chain. This will simulate an actual High-level tank condition and activate the
High-level alarm. Return the Transducer to the original position and secure all wire
fittings.

**A EFG-TXD2- # (# is the size, i.e. A) transducer is available that provides a test port to
pull on the probe without removing the transducer body from the tank nipple. |
