1.1 53SL6000 Controller Overview
The 53SL6000 controller is a functionally robust
instrument capable of performing any one of many
control strategies. Typical control strategies that
can be readily implemented are:
•
Single Loop Control with Remote Setpoint
(PID control)
•
Analog Back-up Control
•
Ratio Control (PID control)
•
Auto/Manual Selector
•
Single Station Cascade Control (Dual PID
control)
•
Single Station Override Control (Dual PID
control)
•
Dual Indicator with Re-Transmitted Proc-
ess Variable (PV)
•
Proportional Speed Floating Control (re-
quires the 2DI/2DO option module)
The complexity of learning software languages or
signal interconnection schemes is eliminated, as all
parameter entries are
prompt-driven
to configure
a control strategy. Mnemonic prompts appear on
the display panel to solicit the necessary re-
sponses.
As listed below, a suite of control modifiers and
signal conditioners is provided to supplement every
control strategy.
Control Modifiers:
•
External Reset Feedback
•
Additive Feedforward
•
External/Internal (Safety) Output Tracking
•
Output High/Low/Rate-of-Change Limiting
•
Process Variable/Internal (Safety) Set-
point Tracking
•
Setpoint High/Low/Rate-of-Change
Limiting
Signal Conditioners:
•
Twelve Linear Segment Characterizer
•
Five Third Order Segment Characterizer
•
Third Order Polynomial
•
Flow Compensation
•
Exponentiation
•
Algebraic Component Combinations
•
Logarithmic Extraction
•
Contact Duration-to-Analog
•
Summation
•
Setpoint Programmer
Every control strategy is also supported with a
standard controller I/O complement that includes
two 0/4-20 mA inputs, two digital/contact inputs,
one 0/4-20 mA output, and two contact outputs.
Also available for every control strategy is addi-
tional functionality provided by optional I/O mod-
ules that mount externally at the rear of the
controller for easy upgrade. Available option mod-
ules are as follows:
•
RS-232 Communications Module - provides
personal computer communication port con-
nectivity (can not coexist with the RS-485 mod-
ule).
•
RS-485 Communications Module - provides
datalink connectivity capabilities (can not co-
exist with the RS-232 module).
•
Universal Analog Input Module - provides one
or two isolated inputs that accept RTD, thermo-
couple, millivolt, volt, and frequency inputs.
The thermocouple and RTD inputs are auto-
matically linearized.
•
2DI/2DO Module - provides two additional digi-
tal inputs and two digital outputs. With this
option, a time proportional or three-step output
can be applied to the 2DO relays for propor-
tional speed floating control.
Power dependent transmitters are provided operat-
ing current from a 50 mA (24 V dc) transmitter
power supply located in the controller.
Tuning the 53SL6000 controller is automated with
EasyTune
, the MicroMod algorithm de-
signed to calculate the optimal PID values for pre-
cise analog control responses to process
deviations.
The 53SL6000 controller is easy to install due to its
small size. Installation depth is only 2 7/8 inches
(73 mm) without option modules and 4 21/32
inches (118.1 mm) with option modules. A 1 inch
(25.4 mm) access space is required for rear termi-
nal plug removal and insertion.
An illustration of the 53SL6000 controller that de-
picts the front display panel and the option modules
is provided in Figure 1-1.
