DESCRIPTION

The P48 Controller accepts either a 0 to 10 VDC or a 0/4 to 20 mA DC signal,

precisely displays the input process signal according to the programmable
scaling points, and provides an accurate output control signal (time proportional
or linear DC) to maintain the process at the desired control point. The
controller’s comprehensive yet simple programming allows it to meet a wide
variety of application requirements.

In the PID control mode the controller operates with on-demand auto-tune,
which will establish the tuning constants. The PID tuning constants may be fine­tuned by the operator at any time and then locked out from further modification.
The controller employs a unique overshoot suppression feature, which allows
the quickest response without excessive overshoot. The unit can be transferred
to operate in the manual mode, providing the operator with direct control of the
output. The controller may also operate in the ON/OFF control mode with
adjustable hysteresis. a second setpoint is available to allow quick selection of
a different setpoint setting.

Dual 4-digit displays allow viewing of the process and setpoint simultaneously.
Front panel indicators inform the operator of the controller and output status. On
some models, the main control output and the alarm outputs are field
replaceable.

Optional alarm(s) can be configured to activate according to a variety of
actions (Absolute HI or LO, Deviation HI or LO, and Band IN or OUT) with

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

CAUTION: Risk of electric shock.

adjustable hysteresis. A standby feature suppresses the alarm during power-up
until the process stabilizes outside the alarm region. The second alarm can be
configured as a secondary PID output (heat/cool applications).

Optional Main Linear DC output (10 V or 20 mA) can be used for control or
process re-transmission purposes. Programmable output update time reduces
valve or actuator activity. The output range can be scaled independent of the
input range.

Optional Second Linear DC output (10 V or 20 mA) provides an independent
process re-transmission, while the main Linear DC output is being used for
control. The output range can be scaled independent of the input range.

Optional Remote Setpoint input (0/4 to 20 mA) allows for cascade control
loops; and allows for remotely driven setpoint signal from computers or other
similar equipment. Straightforward end point scaling with independent filtering
and local/remote transfer option expand the controller’s flexibility.

The optional RS485 serial communication interface provides two-way
communication between a P48 and other compatible equipment such as a printer,
PLC, HMI, or a host computer. In multipoint applications (up to thirty-two), the
address number of each P48 on the line can be programmed separately from 0 to

99. Data from the P48 can be interrogated or changed, and alarm output(s) may
be reset by sending the proper command code via serial communications. PC
software, SFCRM, allows for easy configuration of controller parameters. These
settings can be saved to disk for later use or used for multi-controller down
loading. On-line help is provided within the software.

The unit is constructed of a lightweight, high impact plastic case with a tinted
front panel. The front panel meets NEMA 4X/IP65 specifications when properly
installed. Multiple units can be stacked horizontally or vertically. Modern surface­mount 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 P48 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 controller. An independent and redundant
process limit indicator with alarm outputs is strongly recommended.

FRONT PANEL FEATURES

In the normal operating mode, the unit displays the process value in the upper

display. One of the following parameters can be viewed in the lower display:

- Setpoint

- % Power Output

- Process Deviation

- Blank Display

The user scrolls through these parameters by pressing the D button. If
enabled, the control setpoint or power output (manual mode only) can be
directly modified in this mode.

In the normal operating mode, parameters are selected by use of the P button
and modified by use of the UP and DOWN buttons. Parameters are then entered
by the P button, which advances the user to the next parameter. Pressing the D
button immediately returns the controller to the normal operating mode without
changing the currently selected parameter.

HARDWARE FEATURES

A fast 100 msec input sampling rate provides quick controller response to a
process disturbance, thus providing excellent process control. Measurement
accuracy of 0.1% or better, provides close process control conforming to the
desired control setpoint value.

Low-drift, highly stable circuitry ensures years of reliable and accurate
process control. The recommended two year re-calibration interval is easily
accomplished via the programming menu.

REMOTE SETPOINT INPUT

The remote setpoint input facilitates the use of a remote signal to drive the
controller’s setpoint. The remote signal can be scaled independent to that of the
controller’s range. The controller’s response to local/remote setpoint transfers
can be programmed. Also, the remote signal is filtered by use of an adaptive
filter. With this filter, relatively large filtering time constants can be used
without suffering from long settling times. The time constant and filter disable
band are programmable. Additionally, the remote signal can also be velocity
limited (or ramped) to slow the controller’s response to changes in setpoint. This
results in a steady control response with no overshoot.

LINEAR DC ANALOG OUTPUTS

The Main Linear DC output has independent scaling, programmable output
update time and filter (damping) time. These parameters permit flexibility in
process configuration. The output can be set for 0 to 10 V, 0 to 20 mA or 4 to
20 mA ranges and can be configured for control or for re-transmission of input
or setpoint values.

A Second Linear DC output is dedicated for the re-transmission of the
process input signal. The output can be scaled and converted independent of the
input signal and Main Linear DC output. This output is isolated from the input.

SETPOINT FEATURES

The controller setpoint can be protected from out of range values by
programming the setpoint range limit values. Additionally, safeguards from
inadvertent data entry can be programmed.

A second setpoint can be selected by the user input and/or through the front
panel.

The setpoint ramp feature can be used to control the setpoint value at start-up
or any time a setpoint change is made, at a user programmable rate. This feature
reduces shock to the process and helps to minimize overshoot.

INPUT FEATURES

A programmable input filter can be used to stabilize readings from a process
with varying or oscillating process characteristics, helping to provide better
control.

The programmable user input can be used to control a variety of functions,
such as auto/manual transfer of the controller, reset alarm output(s), etc.

BASIC OPERATION

The P48 controls a process by receiving a linear DC signal representing the
process value, then calculating a control output power value by use of a
modified PID control algorithm. The unit controls the system with the new
output power value to keep the process at setpoint. The PID control algorithm
incorporates features which provide for high control accuracy and low
overshoot from process disturbances.

OUTPUT FEATURES

Programmable output power limits provide protection for processes where
excessive power can cause damage. Programmable output cycle time, output
hysteresis, and dampening can reduce output activity without degrading control
accuracy. The main outputs can operate in PID, ON/OFF, or manual control
modes.

CONTROL AND ALARM OUTPUTS

In addition to the Linear DC output, there are up to three relay outputs
available. Relay outputs can switch user applied AC or DC voltages for control
or alarm purposes.

3

AUTO-TUNE

The P48 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 non-volatile memory. The operator may view and modify the
parameters as desired.

Auto-tune may be invoked either at start-up or at setpoint, depending on the
process requirements. An auto-tune programmable dampening factor produces
various levels of process control and response characteristics.

RS485 SERIAL COMMUNICATIONS

The RS485 communications option allows the connection of up to 32 devices
on a single pair of wires with a distance of up to 4,000 feet and a maximum baud
rate of 9600. Since the same pair of wires are used for both transmit and receive,
only one way communication is possible at any given time. The controller has
a programmable response time to allow the host device adequate time to release
the communication line for a transmission.

Selected parameters from the P48 can be interrogated or changed, and alarm
output(s) may be reset by sending the proper command code via serial
communications. It is also possible to invoke Auto-tune through the serial port.
Serial communications used with SFCRM software allows for easy controller
parameter configuration by computer.

DUAL TIME PROPORTIONAL SYSTEMS

The P48 is available with dual time proportional outputs. The dual outputs
can be used for level or heat/cool applications. The A2 output can be configured
for Secondary (cool) control. This allows for dual PID control or ON/OFF
control with unbalanced hysteresis.

CONTROLLER PROGRAMMING

Front Panel Program Disable allows all of the controller’s set-ups to be
locked-out from further operator intervention after the initial set-up.

The following four programming modes allow the controller to adapt to any
required user-interface level:

MULTIPLE UNIT STACKING

The P48 is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the panel
latch with the screws to the sides of the unit. For horizontal stacking, the panel
latch screws should be at the top and bottom of the unit. The minimum
spacing from center line to center line of units is 1.96" (49.8 mm). This
spacing is the same for vertical or horizontal stacking.

Note: When stacking units, provide adequate panel ventilation to ensure that

the maximum operating temperature range is not exceeded.

APPLICATION

WATER PROCESSING APPLICATION

A city water company needs to maintain a steady flow of water for their
customer needs. They have an existing 0 to 10 VDC flow transmitter to
measure the water flow. They need to control the water flow, have a high and
low alarm, and keep a recorded chart of the flow for later reference. The Main
Linear DC output of the P48 can be used to control the position of water
output values per the desired flow setpoint value. The P48 relay outputs can
be programmed to give a high flow alarm and a low flow alarm. With the
Second Linear DC output model, the flow measurement to the P48 can be
converted from 0-10 V to 4-20 mA and retransmitted to a 4-20 mA chart
recorder.
