STEP 6 PROGRAMMING WITHIN THE HIDDEN LOOP
To enter Hidden Loop, press " for 3 seconds.
Note: Parameters shown bold are the only parameters visible in the Hidden Loop with Factory Settings. Setpoint and Output Power are
factory set for the Display Loop. The remaining parameters can be selected for the Hidden Loop within Module 3
Parameter availability is model and programming dependent.
HIDDEN LOOP
When " is pressed and held for three seconds, the controller advances to the Hidden Loop. The Temperature/Process Value is
shown in the top display. The bottom display alternates between the parameter and its selection/value. # or $ is pressed to change
the selection/value for the shown parameter. The new selection/value is activated after " is pressed. When ! is pressed, the
controller returns to the Display Loop and stores changed selection/values to permanent memory. Hidden Loop parameters may be
locked out in Lockout Module 3.#4 . Some parameters are model and programming dependent.

If the Access Code is set from 1 to 125, in Lockout Module
#4 , Access Code will appear here. By entering the proper Code,
access to the Hidden Loop is permitted. With the factory setting
of 0, Access Code will not appear in the Hidden Loop. A
universal code of 111 can be entered to gain access,
independent of the programmed code number.
SETPOINT SELECT

The SPSL function allows the operator to switch from or to,
setpoint 1 and setpoint 2. In the Display Loop, there is no
annunciator indicating the selected Setpoint, however, the
selected Setpoint value is displayed and activated.
SETPOINT RAMP RATE

The setpoint ramp rate can reduce sudden shock to the
process and reduce overshoot on startup or after setpoint
changes, by ramping the setpoint at a controlled rate. R
annunciator flashes while ramping. With the T16, the ramp rate
HIDDEN LOOP
is always in tenths of degrees per minute, regardless of the
resolution chosen for the process display. With the P16, the
ramp rate is in least-significant (display units) digits per minute.
A value of 0.0 or 0 disables setpoint ramping. Once the ramping
setpoint reaches the target setpoint, the setpoint ramp rate

disengages until the setpoint is changed again. If the ramp value
is changed during ramping, the new ramp rate takes effect. If the
setpoint is ramping prior to starting Auto-Tune, the ramping is
suspended during Auto-Tune and then resumed afterward.
Deviation and band alarms are relative to the target setpoint, not
the ramping setpoint. A slow process may not track the
programmed setpoint rate. At power up, the ramping setpoint is
initialized at the ambient temperature/process value.

In Automatic Mode, the percentage of Output Power is
automatically determined by the controller. In Manual/User
Mode, the percentage of Output Power is adjusted manually
while in the Display Loop. The Control Mode can also be
transferred through the F1 Key or User Input. For more
information, see Control Mode Explanations.
