Programming the Ultrasonic Level Transmitter:
1.
On power-up, a logo is displayed, followed by the preset level/unit
measurement. Changing the level (by float movement)
will be
reflected in the display. If the level is at either of the preset switch
levels S1 or S2 (the upper and lower levels), the display will also be
alternating between the S1 (or S2) status indication with the level
reading. The Switch Active status is also indicated by a flashing
LED.
By rotating the program ring to Position 1 (P1, toward the left) and
then back to Neutral, the program steps to the S1 setting. The level
for activation of the S1 switch is indicated, and may be edited by
turning the program ring to the P2 position (see below). This will
highlight the tenths digit. The digit value is advancing by alternating
the program ring from center to the right P2 position.
Turning the ring to the P1 position accepts that value and moves to
the next digit. Turning the ring to Neutral and then back to P1 will
cycle through all of the digits and then accept the values.
