LOOP BREAK TIME VALUE SUBMENU:
Press d 7) Display flashes 1
st
digit of previous Loop Value.
Press b & c 8) Press b and c buttons to enter a new Loop Value
(0 to 99.59).
Press d 9) Display shows STRD stored message momentarily and then
advances to R.ADJ Reading Adjust Submenu.
Loop Break Time Value allows the user to determine the time interval in MM:SS
(from zero to 99 minutes and 59 seconds) that the Process Value changes at
least 10 counts or if the Input Type is either RTD or Thermocouple, the value
changes 4° Fahrenheit or 2° Celsius. At the specified time interval, if the process
value change is less than the stated rate, flashing
B.TIM will be displayed, the
output 1 will be de-energized, and Alarm 1 energized. Loop break time will be
disabled when the Process Value (PV) enters the control band.
C.J. READING ADJUST SUBMENU:
Press d 10) Display flashes 1 st digit of previous reading adjust value.
Press b & c 11) Press b and c buttons to enter a new Reading Adjust value
(-1999 to 9999).
Press d 12) Display shows STRD stored message momentarily and then
advances to SP.DV Setpoint Deviation Menu.
Reading Offset Adjust (C.J.) allow the user to fine tune a minor error of the
transducer, however some applications may require a large offset adjust.
(Displayed Process Value = Measured Process Value ± R.ADJ). R.ADJ is
adjustable between -1999 to 9999.
SETPOINT DEVIATION ENABLE/DISABLE SUBMENU:
Press d 13) Display advances to Setpoint Deviation ENBL Enable or DSBL
Disable Submenu and flashes the previous selection.
Press b 14) Scroll through the available selections: ENBL or DSBL.
Press d 15) Display shows STRD stored message momentarily and then
advances to CAL. Menu.
Setpoint Deviation Submenu, if “enabled”, allows changes to Setpoint 1 to be
made automatically to Setpoint 2. This mode is very helpful if the Process Value
changes often. In Setpoint Deviation Mode, set SP2 a certain number of degrees
or counts away from SP1 - this relation remains fixed when SP1 is changed. For
instance: Setting SP1=200 and SP2=20 and enabling
SP.DV means that the
absolute value of SP2=220. Moving SP1 to 300, the absolute value of SP2
becomes 320.
