DESCRIPTION
The PSC is a setpoint controller suitable for time vs. process control
applications. The PSC Controller accepts either a 0 to 10 VDC or a 4 to 20 mA
DC input signal, precisely scales the process signal, according to programmable
scaling points, and provides an accurate output control signal (time proportional
or linear) to maintain a process at the desired control point. A comprehensive set
of easy to use steps allows the controller to satisfy various applications. The user
input can be programmed to perform a variety of controller functions.
Dual 4-digit displays allow viewing of the measured process value and
setpoint or the process and profile status simultaneously. Front panel indicators
inform the operator of controller status and output states. Replaceable output
modules (Relay, logic/SSR drive or Triac) can be fitted to the main control
output, alarm output(s) or timed event output(s), and secondary output.
The PSC has been designed to simplify the set-up and operation of a
controlled setpoint profile program. The setpoint program is easily entered and
controlled through the front panel. Full display capabilities keep the operator
informed of the process value, profile status, output states, and setpoint value.
The controller can operate in the standard PID control mode for both Output
1 and Output 2 with on-demand auto-tune which establishes the PID gain set.
The PID gain set can be fine tuned by the operator at any time or may be locked
from further modification. The unit can be transferred to the manual control
mode providing the operator with direct control of the output.
The PSC features four programs or profile recipes, each with up to eight
ramp/soak segments, which can be easily stored and executed at any time.
Longer profiles can be achieved by linking one or more profiles together,
creating a single profile of up to 32 ramp/soak segments. Process profile
conformity is assured during either soak (hold) phases or both ramp and hold
phases by an adjustable error band parameter. The program repeat function
cycles the profile either continuously or a set number of times. Power-on options
automatically re-start, stop, or resume a running profile. The profile can be
controlled via the front panel buttons, the user input, or the optional serial
communications port.

DESCRIPTION (Cont’d)
Four control points, each having a setpoint and PID parameter set, are
available for instant front panel implementation during batch changeover, or
other process conditions. A control point may have its PID gain set values
disabled when implementing the control point.
The optional RS485 multidrop serial communications interface provides the
capability of two-way communication between a PSC unit and other compatible
equipment such as a printer, a programmable controller, or a host computer. In
multipoint applications the address number of each unit on the line can be
programmed from 0 to 99. Up to thirty-two units can be installed on a single pair
of wires. The Setpoint value, % Output Power, Setpoint Ramp Rate, etc. can be
interrogated or changed by sending the proper command code via serial
communications. Alarm output(s) may also be reset via the serial communications
interface option.
Optional alarm output(s) may be configured to operate as a timed event
output or as a standard alarm output. As an alarm output it may be configured to
activate according to a variety of actions (Absolute HI or LO, Deviation HI or
LO, or Band IN or OUT) with adjustable hysteresis. Also, a standby feature
suppresses the output(s) on power-up until the process stabilizes outside the
alarm region. Timed event output(s) allow the controller to activate other
equipment while a programmed profile is running. Each profile can define up to
16 event states (phases), for each output(s).
An optional secondary output is available for processes that require cooling
which provides increased control accuracy and response.
The optional linear 4 to 20 mA or 0 to 10 VDC output signal is available to
interface with final actuators, chart recorders, indicators, or other controllers. The
output signal can be digitally scaled and selected to transmit one of the following:
% Output Power
Measurement Value
Measurement Value Deviation
Setpoint Value
An optional Type 4X/IP65 rated bezel is available for washdown and/or dirty
environments, when properly installed. Modern surface-mount technology,
extensive testing, plus high immunity to noise interference, makes the controller
extremely reliable in industrial environments.

SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the PSC to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons or
equipment in the event of a fault to the unit. An independent and redundant
process limit indicator with alarm outputs is strongly recommended. The
indicators should have input sensors and AC power feeds independent from
other equipment.

BASIC OPERATION
The PSC controls the process profile of a system by measuring the input
signal, comparing it to the setpoint value of the profile in progress, and
calculates the new output power value by use of a modified PID control
algorithm. The unit controls the system with the new output power value so the
process value conforms to the profile. The PID control algorithm incorporates
features which provide high control accuracy and low disturbance overshoot.
FRONT PANEL FEATURES
In the normal display mode, the unit will display the scaled process value in
the upper display. One of five other parameters may be selected for viewing in
the lower display:
Target setpoint
% Output Power
Profile Status
Profile phase time remaining
Blank the lower display.
The profile status display indicates the active program number with the
current ramp or hold phase of the program. The profile can be started, stopped,
advanced, etc., from the front panel when the profile status display is viewed, if
not locked from access.
The phase time remaining display, shows the time remaining in a ramp or hold
phase and, if not locked from access, may be changed on-line to effect temporary
changes to the profile. Additionally, the target setpoint and % output power
(manual mode only) may also be changed on-line or locked from operator access.
From the normal operating mode, parameters are selected by use of the PAR
button and modified by use of the UP and DOWN buttons. Parameters are then
entered by the PAR button, which advances the user to the next parameter.
Pressing the DSP button immediately returns the controller to the normal
operating mode from any parameter module. The controller configuration and
parameter settings are stored in an internal E

(Detailed in the operator’s manual)
SETPOINT FEATURES
The controller’s setpoint can be protected from out of range values, by
programming the setpoint range limit values. Additionally, safeguards from
inadvertent data entry can also be programmed.
The setpoint ramp feature ramps the setpoint value at start-up or any time a
setpoint change is made, at a user programmable rate, independent of a
programmed profile. This feature reduces shock to the process and also helps to
minimize overshoot.
The active setpoint, which can be a running profile, may also be transmitted
by the linear DC output for slave control loops.
Four control points are available which can be implemented at any time. Each
control point is programmed independently, with each having a setpoint and a
PID gain set value. With gain value changes, the output power control signal
will not “bump” resulting in a smooth control transition.
OUTPUT FEATURES
Programmable output power limits provide protection for processes where
too much power can cause damage. Automatic signal overdrive detection can be
used to define the state of the output channels, when this situation occurs. With
adjustable time proportioning-cycle time and programmable D.C. Linear output,
the controller can satisfy a wide variety of output requirements.
During execution of a profile, two independent timed event outputs are
available to control or signal other equipment. The event outputs use the
alarm channels.
The RS485 Communication option allows the user to access various
controller parameters such as the setpoint, % output power, % proportional
band, etc. The controller may be setup to transmit various parameters at a
programmable automatic print rate.
INPUT FEATURES
AUTO-TUNE
A programmable input filter can be used to stabilize readings from a process
with varying or oscillating characteristics, helping to provide better
process control.
Scaling points allow the controller to display in any engineering unit; flow,
level, pressure temperature, etc. Scaling points are used in conjunction with the
programmable rounding increment to stabilize a jittery or otherwise hard to read
process signal for better indication.
A programmable User Input is available to control a variety of controller
functions, such as profile control, auto/manual transfer, serial communication
print requests, etc.
The model PSC has an auto-tune feature which, on demand, automatically
determines the PID control parameters for a particular process. After completion
of auto-tune, the PID parameters are automatically optimized for that process
and loaded into nonvolatile memory. The operator may view and modify the
parameters as desired.
Auto-tune may be invoked at start-up, while ramping, or at setpoint,
depending on the process requirements. A programmable auto-tune damping
factor produces various levels of process control and response characteristics.
PROFILE PROGRAMMING
Profiles are programmed independently of each other and are separate from the
configuration of other controller parameters. Each profile has parameters for error
band (profile conformity), linking, auto-start and program repeat cycles. Profiles
may be altered during execution, so changes take effect as the profile advances.
4
CONTROLLER PROGRAMMING
The model PSC has been designed to reduce the operator interaction with the
controller while still maintaining a high degree of control accuracy and user
flexibility. Front panel program disable allows all of the controller’s set-ups to be
locked-out from further operator intervention after the initial parameter set-up.
The programming of the controller is divided into four sections:
Hidden Mode
Protected Mode
Unprotected Mode
Configuration Mode
These four programming modes allow the controller to adapt to any required
user-interface level.
OUTPUT VARIATIONS WITH RS485 OPTION
The Dual Alarm or the Secondary with Alarm output, with RS485 option,
does not have independent outputs. In this case, the secondary output and/or

main output (OP1) can be fitted with any output module. Output modules are
shipped separately and must be installed by the user.
