ANALOG RETRANSMISSION OPERATION
The analog retransmission allows the Process Variable to be sent as an analog signal to
an external device. The signal may be either 2 to 10 VDC (option RV) or 4 to 20 mADC
(standard). The output may be changed in the field from one to the other by the toggle
switch located on the top printed circuit board, factory standard is mADC.
Wire the output as shown on page 5.
To set up the analog retransmission, first determine the scale range that the analog signal
will represent. The maximum scale is 9999 counts. In the Secure menu set
P0L
for the
scale value that will be represented by the low end of the analog signal (2 Volts or 4 mA).
Set
P0H
for the scale value that will be represented by the high end of the analog signal
(10 Volts or 20 mA). Operation is automatic. There are no further programming steps
required. The values of
P0L
and
P0H
must be within the programmed scale range. The
scale range is set by the
SCAL
and
SCAH
in the Secure menu.
PUMP RUN TIME OPERATION
The pump run time is indicated in hours of operation since the last time that the run time
meter was reset for a specific pump. The Pump Run Time key on the front of the
unit will display run time for both pumps when depressed. Run time for pump 1 is in the
top display and pump 2 is in the lower display. To reset the pump run time go to the menu
items
P1rn and P2rn in the Secondary Menu. When in the corresponding menu item hold
the ENTER button for approximately two seconds. The display will blank out for
about 1 second and the run time will display 0. These menu items can be locked out by
the
PrSt menu item in the Secure Menu.
