SEQUENCING WITH MULTIPLE SUPERVISOR CONTROLS
entered by a separate password in the Calibration menu to protect from inadvertent
changes. If the password is not equal to zero, cursor to the password line, press the ENTER
key and then enter a value that is four more than the existing number. Press the ENTER
key and the number should go to zero. Repeat process if a keying error occurs that does
not release the password.
Cursor to the line that reads CAL P2. The display will show the (current P2 reading) and the
calibration parameter ( + 7 to -7). Press the ENTER key to adjust the value. The Up
arrow key will increase the reading and the Down arrow key will decrease the reading.
Use these keys to correct the P2 reading, then push the ENTER key. The ENTER key
must be pressed after setting the calibration parameter to make it permanent. Return to the
main display by pressing ESC and check to make sure the pressure is correct.
2.12 CALIBRATION OF P2 PRESSURE TRANSDUCERS – SUPERVISOR II
DELUXE
Because each machine has it's own pressure transducer it is possible that after a long peri-
od of time these can read differently. If this happens the supervisors should be re-calibrat-
ed. This re-calibration is best done when the system is at a stable pressure. Measure the
pressure using an independent gauge then change the calibration parameter for P2 so that
the supervisor reads the same as the gauge. The changing of the calibration parameters is
entered by a special key sequence to protect from inadvertent change. The key sequence
is : Logo , Up arrow , Display ; Lamp Test , Program . The first line
of the display should read CAL P1 , if not push the Display key and try again. If the first line
of the display reads CAL P1 push the Program key, and the first line of the display should
read CAL P2. The second line of the display will show the calibration parameter ( + 7 to -7)
and the current P2 reading corrected by the calibration parameter. The Up arrow key
will increase the reading and the Lamp Test will decrease the reading. Use these keys
to correct the P2 reading, then push the program key. The program key must be pressed
after setting the calibration parameter to make it permanent. Return to the main display and
check to make sure the pressure is correct.
2.13 FULL LOAD FEATURE
The full load feature energizes a solenoid valve on the machine that forces the base
machine/s to full load when being sequenced. Spiral valve machines may also require a
relay that de-energizes the spiral control solenoid valve during full load mode.
