Unlocking The Features; Selecting "Sp Cnf" Setpoint Configuration Features - Omega DP461-S User Manual

10.2

UNLOCKING THE FEATURES

All setpoint values and features can be set via the front-panel buttons or the
optional serial communications boards (RS-232 or RS-422/485). Control
from the front-panel buttons can be locked out by jumpers on S3A and S3C
on the main board or by setting lockout bits "L3C.2", and "L3C.6" in Lockout
configuration "L3 CNF".
1. Check that main board jumpers S3A and S3C are installed (to permit
memory storage of program and data along with button controls).
NOTE: Jumper S3B should NOT be installed. This jumper is reserved
Note
for factory recalibration!
2. Press the 'MENU' button to see "L1 CNF" and then press the 'MIN'
button to view "L1C.1=0" if "SP 1" is unlocked. If "L1C.1=1", change to
equal "0" by pressing the 'MAX' button.
3. Press the 'MIN' button again to advance to "L1C.2" and set equal to "0"
to unlock "SP 2".
4. Repeat for "L1C.3=0" and "L1C.4=0" to access "SP 3" and "SP 4".
5. Press the 'MENU' button to save these choices and advance to "L2
CNF". Skip over "L2 CNF" by pressing the 'MENU' button and advance
to "L3 CNF".
6. Press the 'MIN' and 'MAX' buttons to set "L3C.2=0", "L3C.3=0",
"L3C.4=0", "L3C.5=0", "L3C.6=0", "L3C.7=0" to gain access to the
programming for the setpoints. All changes are then saved by pressing
the 'MENU' button.

10.3 SELECTING "SP CNF" SETPOINT CONFIGURATION FEATURES

These eight bits select the modes for "SP 1" and "SP 2" (see Section 10.5 for
"SP 3" and "SP 4").
1. Press the 'MENU' button until "SP CNF" is displayed, then press the 'MIN'
button to sequence through the selections. Use the 'MAX' button to
choose alternate choice.
2. "SPC.1=0" makes "SP 1" active ABOVE its level;
"SPC.1=1" sets "SP 1" active BELOW.
3. "SPC.2=0" turns "SP 1" transistor ON when "SP 1" is active.
"SPC.2=1" turns it OFF.
4. "SPC.3=0" compares the "SP 1" level to the UNFILTERED
measurements.
"SPC.3=1" compares "SP 1" to the FILTERED measurements.
5. "SPC.4=0" makes "SP 2" active ABOVE setpoint.
"SPC.4=1" makes "SP 2" active BELOW setpoint.
6. "SPC.5=0" turns "SP 2" transistor ON when "SP 2" is active.
"SPC.5=1" turns it OFF.
