Part No. 4801- 5085 Rev 5-01 Farm Hand Alert Alarm 6
the Alert Alarm can have different high and low limit setpoints. For Water Quantity, the Display
Indicator shows the current setting for the high limit setpoint.
To adjust these settings, press the Mode button until you see the green LED beside the High Limit
on the Display Indicator. Note the Select button next to the sensor or parameter setting you want
to adjust. Press the Select button and you will see the reading begin to flash, indicating that you
can change the setting by using the Plus (+) and Minus (-) buttons. Use the Plus (+) button to raise
the value, and the Minus (-) button to lower the value. Although Sensor 1,2 and 3 limits can be set
individually to the same value, see Section 8.1 for an abbreviated procedure if it is desired to use
the same limits for all three sensors.
The Water Quantity Sensor also has a high limit setpoint. The alarm will sound if the water
quantity goes over the high limit setpoint. These are adjusted as explained above for the
temperature sensors.
Water Total does not have a high limit setpoint and can not be used to trigger an alarm. See
Section 6.2 for a discussion of Water Total.
Low Limit Setpoints
The Low Limit Setpoint for Sensors 1,2 and 3
is the temperature used to control the low side
at which the alarm will sound. For example,
if the Low Limit Setpoint is set to 70 degrees
and the temperature drops to less than 70
degrees, the alarm will sound. Each of the
three temperature sensors in the Alert Alarm
can have different high and low limit setpoints.
The Water Quantity Sensor also has a low limit setpoint. The alarm will sound if the water
quantity goes below the low limit setpoint. These are adjusted as explained above for the
temperature sensors.
Water Total does not have a low limit setpoint and can not be used to trigger an alarm. See
Section 6.2 for a discussion of Water Total.
Reset
For Sensor 1, 2, 3 and Water Quantity, the setting of the Reset enables or disables the Alarm for
each sensor. The sensor can either be enabled (ON) or disabled (OFF). To adjust these settings,
press the mode button until you see the green LED beside “Reset” in the Display Indicator. Press
the Select button next to the sensor or parameter setting you want to adjust, then use the Plus (+)
button to set the value to ON and the Minus (-) button to set the value to OFF.
If Sensor 1, 2, 3 or the Water Quantity sensor are set to OFF, the Channel Display will flash
alternatively between the display reading and the word “OFF”.
As discussed in the next section, Water Total is used to count the total quantity of water recorded
by the water quantity sensor. The Reset button is used to set the water total reading to zero. To
adjust this setting, press the mode button until you see the green LED beside “Reset” in the
Display Indicator. Press the Select button next to the Water Total. To reset the water total to zero,
the Reset must be set to “YES”. Use the Plus (+) button to set the value to “YES” and the Minus (-
) button to set the value to “NO”.
