To Enter the Configuration Process
• Hold the magnet to the switch for 3 seconds
• The green LED will go off
• Remove the magnet
• Process begins
The unit will flash the values of the three Field parameters in order, repeatedly.
The pattern begins with
• Field 1’s green LED pulses
• 2 seconds between Field 1 and Field 2
• Field 2’s green LED pulses
• 2 seconds between Field 2 and Field 3
• Field 3’s LED pulses
• 4 seconds between Field 3 and returning to Field 1;
the four (4) second gap helps the user identify Field 1, the starting point of the
sequence, even after the sequences of pulses have repeated several times. The
LCD-8’s default configuration is represented in Figure 6, above.
After changing the parameters of any field, the LCD-8 returns to the display
mode.
To Display the Current Values
Hold the magnet over the magnetic switch for 3 seconds. The green LED turns
off then flashes a brief message (3 short pulses and a long pulse), and return to
normal mode. This can be done even if the parameters have not been changed.
To Change a Field’s Parameters
Hold the magnet to the switch during the pause after that field. The green
LED turns and remains on until the magnet is removed. That sets the value to 1.
Positioning the magnet on again, the LED turns on, then remove the magnet: that
sets that value to 2. Continue in this fashion.
There are two (2) seconds between swipes. After 2 seconds, the LCD-8 main-
tains the entered value and returns to display mode. If a value exceeds parameters,
the green LED flickers briefly and returns to displaying the previous values.
Note: if the magnet is held for 3 seconds during the process of setting a value
(having been released at least once), the green LED flickers briefly and restarts the
display process.
To Abandon the Process with No Changes
Allow the LCD-8 to sit for two (2) minutes. The unit will flash the green LED
quickly for 2 seconds and return to normal operation, displaying a steady green LED.
This can be done at any time in the process.
Note: changes to the operating temperature or the state of the low-
temperature lockout take effect immediately. Changing the hold-on time does
not affect any active hold-on cycles; new values will be used the next time a
hold-on cycle initiates.
