The contact integrator can only be set for multiples of
the totalizer multiplier. For example, if it is desired to
have a sampler take a sample every 10,000 gallons and
the totalizer multiplier is 1,000, then the contact integrator
would be set to 0010.
To set the contact integrator, use the RIGHT arrow key
to move the cursor under the digit to be changed and the
UP or DOWN arrow keys to select the desired value.
After the desired value has been set, press the ENTER
key. The following screen will appear:
INTEGRATOR PULSE WIDTH
ON FOR
0
002 X .0655 SEC.
This screen allows the setting of the pulse width or
duration of the contact integrator. The on time can be set
for multiples of .0655 seconds. For example, if the
contact closure must be at least 100 milliseconds, then the
pulse width must be set for 0002 which would give a time
of 131 milliseconds. If the pulse width must be 30
seconds in duration, then the value would be set at 0459
which would give a time of 30.06 seconds.
Use the RIGHT arrow key to move the cursor under the
digit to be changed and the UP or DOWN arrow keys to
change to the desired value. Press the ENTER key and the
following screen will appear:
SET POINT # 01
ON AT
XX% OFF AT XX%
This screen allows the setting of the set points for low or
high alarms and the dead band. These values are in percent
of the full scale value.
To make the set point a low alarm,
the ON value must be lower than the OFF value.
For
example, if the ON value was 30% and the OFF value was
35% then this set point alarm will be activated below a flow
rate of 30% of full scale and will be deactivated at a flow
rate above 35% of full scale.
To make the set point a high alarm, the ON value
must be higher than the OFF value.
For example, if the
ON value was 60% and the OFF value was 50% then this
set point alarm will be activated at a flow rate above 60%
of full scale and will be deactivated at a flow rate below
50% of full scale.
To set the desired values, use the RIGHT arrow key to
move the line under the ON or OFF values and use the
UP or DOWN arrow keys to change the values. Press the
ENTER key to store the new values. The screen will
advance to the second set point. After the second set point
has been entered the following screen will appear:
RELAY ASSIGNMENT
RELAY 01 =>
ECHO
In this screen the four relays are assigned to the alarm on
which they are to activate. The assignments available are:
EEPRM = Failure of the EEPROM unit
OVRR = Fluid level above max. full scale
4-20 = 4-20 mA output current loop open
CINT = Contact integrator
TOTL = Contact on totalizer increment
PNT#2 = Set point number 2
PNT#1 = Set point number 1
Once the desired alarm has been selected for relay #1,
press the ENTER key to store this assignment. The screen
will then advance through the three remaining relays.
After the last relay assignment has been made the
following screen will appear:
4-20 CURRENT CALIBRATION
PRESS UP TO CHANGE
This screen allows the entry into the calibration screens
for the 4-20 mA current output. Press the UP arrow key
and the following screen will appear:
4-20 M A CALIBRATION
ZERO WORD = XXXX
This screen allows the adjustment of the zero output to
4 mA. The 4-20 mA output can be monitored on the test
jacks on the bottom of the back half of the housing, red
jack positive, black jack negative.
The 4-20 mA output
must be connected to a load for the test points to work.
Use
the RIGHT arrow key to position the line under the digit
to be adjusted. Fine adjustment is made on the right digit
with the adjustment becoming more coarse with each
digit to the left. Use the UP or DOWN arrow keys to
adjust for the correct value. The value of the Zero Word
is for reference only. Press the ENTER key to store the
value. The following screen will appear:
4-20 M A CALIBRATION
SPAN WORD = XXXX
This screen allows the adjustment of span to 20 mA.
The 4-20 mA output can be monitored on the test jacks on
the bottom of the back half of the housing. Use the
RIGHT arrow key to position the line under the digit to
be adjusted. Fine adjustment is made on the right digit
with the adjustment becoming more coarse with each
digit to the left. Use the UP or DOWN arrow keys to
adjust for the correct value. The value of the Span Word
is for reference only. Press the ENTER key to store the
value. The following screen will appear:
4-20 M A CALIBRATION
DEFAULT WORD = XXXX
