MENU SELECTIONS
PRIMARY MENU
Press INDEX to advance to the next menu item. Press UP ARROW or DOWN ARROW
to change the value in the display. Press ENTER to retain the value.
SP
Set Point Adjust, Control Point.
SECONDARY MENU
Press UP ARROW & ENTER simultaneously. Press INDEX to advance to the next menu
item. Press UP ARROW or DOWN ARROW to change the value in the display. Press
ENTER to retain the value.
ALLo Alarm Low: The Low Alarm point is usually set below the Set Point.
ALHi Alarm High: The High Alarm Point is usually set above the Set Point.
CY
Cycle Rate and output selection: Select OnOF, 1, 2 to 80 seconds total cycle time.
ONOF A setting of ONOF allows the control to operate as a simple on/off mode.
This setting forces the control to turn off at set point, and on at the set point
plus the differential (SP_d). When selected, the tunE, Pb, rES, OFS, rtE,
and ArUP selections in the Secondary menu and the SPOL and SPOH
selections in the Secure menu are suppressed.
1
A setting of 1 is recommended for solid state outputs (SSR or 5VDC).
2 to 80 Time Proportioning Control is adjustable in 1 sec. steps. Recommended for
mechanical outputs (relays, solenoids, etc.). For best contact life, a time
should be selected that is as long as possible without causing the process
to wander.
SP_d Set Point On-Off Differential. (Only appears if CY is set to ONOF.) Select 1 to 999°F.
This value will be negative for reverse acting set points, and positive for direct acting
outputs. Set the value for the amount of temperature difference between the turn
off point (set point) and the turn on point.
tunE Tuning Choice: Select SELF or Pid.
SELF The Controller will evaluate the Process and select the PID values to
maintain good control. The ramp function (rt) cannot be selected while
SELF tunE is active. The temperature descriptor will flash while SELF tunE
is active. The control will switch to Pid tunE when the tuning function is
complete.
Pid
Manually adjust the PID values. PID control consists of three basic
parameters, Proportional Band (Gain), Reset Time (Integral), and Rate
Time (Derivative).
Pb
Proportional Band (Bandwidth): Select 5 to 5000 °F (3 to 2778 °C).
rES
Automatic Reset Time: Select OFF, 0.1 to 99.9 minutes. Select OFF
to switch to OFS.
OFS Manual Offset Correction: Select OFF, 0.1 to 99.9%. Select OFF to
switch to rES.
rtE
Rate Time. Select OFF, 0.01 to 99.99 minutes (Derivative).

ArUP Anti- Reset Wind-up Feature: Select On or OFF.
On
If ArUP is On the accumulated Reset Offset value will be cleared to 0%
when the process input is not within the Proportional Band.
OFF
If ArUP is OFF, the accumulated Reset Offset Value is retained in memory
when the process input is not within the Proportional Band.
rt
Ramp Time: Select OFF, 00.01 to 99.59 (HH.MM). When value is entered, control
calculates a ramp slope from the current temperature to SP over the time entered.
Changing rt or SP (or pressing ENTER at either menu item) restarts the ramp
function, and re-calculates the slope. The right hand decimal point of the display
will flash while the ramp function is active. Self tunE cannot be selected while the
ramp function is active. Selecting OFF will stop a current ramp and drive the output
as necessary to reach set point
InPC Input Correction: Select ±500 °F (±278 °C). This feature allows the input value to
be changed to agree with an external reference or to compensate for sensor error.
Note: InPC is reset to zero when the input type is changed, or when decimal
position is changed.
FiLt
Digital Filter: Select OFF, 1 to 99. In some cases the time constant of the sensor,
or noise could cause the display to jump enough to be unreadable. A setting of 2
is usually sufficient to provide enough filtering for most cases, (2 represents
approximately a 1 second time constant). When the 0.1 degree resolution is
selected this should be increased to 4. If this value is set too high, controllability
will suffer.
SECURE MENU
Hold UP ARROW & ENTER for 5 Seconds. Press INDEX to advance to the next menu item.
Press UP ARROW or DOWN ARROW to change the value in the display. Press ENTER
to retain the value.
SECr Security Code: See the Security Level Selection and the Password Table in this
manual in order to enter the correct password.
InP
Input Type: Select one of the following. The selections are limited to the input type
you ordered. If you ordered a thermocouple input control, make your selection from
the thermocouple list. If you ordered an RTD input, select from the RTD list.
Thermocouple selections:
J-IC Type “J” Thermocouple, Iron/Constantan (NIST)
CA
Type “K” Thermocouple Chromel/Alumel
t-
Type “T” Thermocouple Copper/Constantan
RTD selection:
P385 100 ohm Platinum (DIN 0.00385
Ω/Ω
/°C), element code PD.
F-C
Select temperature descriptor for Fahrenheit or Celsius.
F
°F descriptor is On and temperature inputs will be displayed in actual
degrees Fahrenheit.
C
°C descriptor is On and temperature inputs will be displayed in actual
degrees Celsius.
dPt
Decimal Point Positioning: Select 0 or 0.0. This only affects the Process Value, SP,
ALLo, ALHi, and InPC.
0
No decimal Point is selected.
0.0
One decimal place is selected. If the Process Value moves outside of the
decimal point range ends (-199.9 to +999.9), the Process Value display will
autorange to whole degree resolution. When the Process Value returns to
the decimal point range, the display will autorange back to tenth degree
resolution.
