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 2 PROM device.
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.
