Bindicator SonoTracker Ultrasonic Liquid Level, Installation & Operation Manual

Page: 65 / 96

Note: The value entered for the 4/0 mA operation point does not have to be smaller than the value entered for
the 20 mA operation point.
Note: See Figure 10c: Transducer Menu, for information on setting the threshold time for echo loss.
43 ADD
This menu is used to add current output channels (up to two) to the displayed vessel. Note that the current
output must be added before the Set parameters can be input.
The top line of the display shows the first available current output. The bottom line shows the slot number of the
Current Output PCB and the channel number for the current output on the Current Output PCB. Pressing the Up
and Down Arrow Keys cycles through all other unassigned current output channels. Pressing the Enter Key adds
the current output channel.44 Delete
This menu allows previously added current outputs to be removed from the displayed channel. The top line of
the display shows an assigned current output number. The bottom line shows the slot number of the Current
Output PCB and the channel number on the Current Output PCB.
To delete a current output, cycle through the current outputs by pressing the Up and Down Arrow Keys until
the one you want to delete is displayed; then press the Enter Key. To prevent accidental deletion, the display
requests verification that you want to delete the current output channel. If the response is Yes, then I/O
CHANNEL DELETED displays to confirm the channel deletion. This current output channel is now available for
use again.
45 TEST
This function allows manual activation of current output channels outside of normal control. The system issues a
warning that the automatic control of current outputs assigned to the currently selected channel is transferred to
manual control, and requests verification for what you want to do.
After the warning message, if more than one 0/4-20 has been assigned for this vessel, a selection of the two 0/4-
20 channels is offered. After you select a 0/4-20 channel, a typical 0/4-20 Test function display looks like this:
Iout 1 :SL 03: Ch1
4mA: (Up/Down)
• Iout02 is the current 0/4-20 channel reference number. All actions performed are with respect to this
number.
• SL 03 is the slot number of the Current Output PCB.
• Ch1 is the channel number on the Current Output PCB. Each Current Output PCB has eight multiplexed
current output channels.
• 0-4mA is the current that is being sent to the 0/4-20 channel being tested. If the current mode is
0-20mA, the test current output ranges from 0 mA to 20 mA in 2 mA steps. If in the 4-20mA mode, the
test current output ranges from 4 mA to 20 mA in 2 mA steps.
• More or Less refers to the increase (More) or decrease (Less) of the output. Pressing the up arrow key
increases the output in 2 mA steps; pressing the down arrow key decreases the output in 2 mA steps.
