Hb.U
: Press the UP or DOWN ARROW to select the holdback value
(in display units).
rmP.U
: Press the UP or DOWN ARROW to toggle between ramp
units (SEc, min or Hour). Controller will default to “SEc.”
dwL.U
: Press the UP or DOWN ARROW to toggle between dwell
units (SEc, min or Hour). Controller will default to “SEc.”
Cyc.n
: Press the UP or DOWN ARROW to set the number of
program cycles (1 to 999 or cont). The controller will default to
“cont.”
SEG.n
: Press the UP or DOWN ARROW to select the segment
number (1-8 in 8 segment models, 1-16 in 4x16 models).
tYPE
: Press the UP or DOWN ARROW to select the segment type
[End (end of program), rmP.r = ramp rate (ramp to a specified
setpoint at a set rate), rmp.t = ramp time (ramp to a specified
temperature in a set time), dwEll (to maintain a constant
temperature for a set time), StEP (climb instantaneously from
current to specified temperature), cALL (to call a program as a
subroutine, available only on 4x16 programmable models)]. The
controller will default to “End.” Other parameters used with tYPE
include; tGt target setpoint), Rate (rate of temperature increase)
and dur (time to target setpoint or time to dwell).
End.t
: End segment type: dwELL (dwell continuous), rSEt (reset) and
S OP (End Segment Output power level.
AL LiSt (Alarm List)
IdHi
: Deviation High Alarm.
Atun LiSt
: (Autotune List)
tunE
: One-shot autotune enable.
drA
: Adaptive tune enable.
drA.t
: Adaptive tune trigger level in display units. Range = 1 9999.
