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

HARDWARE FEATURES

The fast 100 msec input sampling rate provides quick controller response to

a process disturbance for excellent process control. Measurement accuracy of

0.15% provides closer process control conforming to the desired control setpoint

value.

The unit will accept either a 0 to 10 VDC or a 4 to 20 mADC input signal.

The A.C. input power is switch selectable, allowing the unit to operate from

either 115 VAC or 230 VAC. Since the controller is serviceable from the front

of the panel, the output modules may be easily changed or replaced without

disturbing the wiring behind the panel and

NO re-programming is required. The

standard model simply requires pressing a

latch to remove the unit. The Type 4X/IP65

rated model utilizes two panel securing

screws and a neoprene gasket to guarantee

a water tight seal, when properly installed.

Low-drift, highly stable circuit design

ensures years of reliable and accurate

process control. The recommended two

year re-calibration interval is easily

accomplished via the programming menu.
