DESCRIPTION
The T48 Controller accepts signals from a variety of temperature sensors
(thermocouple or RTD elements), precisely displays the process temperature,
and provides an accurate output control signal (time proportional or linear DC)
to maintain the process at the desired temperature. The controller’s
comprehensive yet simple programming allows it to meet a wide variety of
application requirements.
The controller operates in the PID control mode for both heating and cooling,
with on-demand auto-tune, which will establish the tuning constants. The PID
tuning constants may be fine-tuned 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 be
programmed to operate in the ON/OFF control mode with adjustable hysteresis.
A second setpoint is available on select models to allow quick selection of a
different setpoint setting.
Dual 4-digit displays allow viewing of the process temperature and setpoint
simultaneously. Front panel indicators inform the operator of the controller and
output status. On many 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, Band IN or OUT, and Heater Current
Break) with adjustable hysteresis. A standby feature suppresses the alarm during
power-up until the temperature 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
temperature 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
temperature 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 Heater Current Monitor provides a direct readout of process heater
current. An alarm can be programmed to signal when the heater has failed. This
provides early warning of system failure before product quality is affected.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION:
Risk of electric shock.

Optional Remote Setpoint input (0/4 to 20 mA) allows for cascade control
loops, where tighter control is required; 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 T48 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 T48 on the line can be programmed from 0 to
99. Data from the T48 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
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 T48 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
temperature limit indicator with alarm outputs is strongly recommended.

BASIC OPERATION
The T48 controls a process temperature by measuring the temperature via an
input probe, 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 temperature at setpoint. The PID control algorithm
incorporates features which provide for high control accuracy and low
temperature overshoot from process disturbances.
A Second Linear DC output is dedicated for retransmission of input
temperature. The output can be scaled and converted independent of the input
and Main Linear DC output. This output is isolated from the input.
SETPOINT FEATURES
FRONT PANEL FEATURES
In the normal operating mode, the unit displays the process temperature
in the upper display. One of the following parameters can be viewed in the
lower display:
- Setpoint
- % Power Output
- Temperature Deviation
- Heater Current
- Temperature symbol (F or C)
- 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.
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 value can be programmed which can be made active by a
user input and/or through the front panel on selected models.
The setpoint ramp feature ramps the setpoint value at start-up or any time a
setpoint change is made, at a user programmable rate. This feature reduces
thermal shock to the process and helps to minimize temperature overshoot.
INPUT FEATURES
A programmable input filter can be used to stabilize readings from a process
with varying or oscillating temperature characteristics, helping to provide better
temperature control. A programmable temperature shift function can be used to
compensate for probe errors or to have multiple T48 units indicate the same
nominal temperature.
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), transfer to
second setpoint, etc.
OUTPUT FEATURES
HARDWARE FEATURES
A fast 100 msec input sampling rate provides quick controller response to a
process disturbance, thus providing excellent temperature control. Measurement
accuracy of 0.3% of span ±1°C or better, provides close process control
conforming to the desired control setpoint value. The T48 accepts a variety of
both thermocouple and RTD temperature probes. An output board contains the
Main Control output, Alarm 1 output, Alarm 2/Cooling output, and/or Linear
DC output. Since the controller is serviceable from the front of the panel, the
output board (on some models) may be easily changed or replaced without
disturbing the wiring behind the panel. No re-programming is required when
changing or replacing the output board for units without the Linear DC output
option. Units with the linear output option require calibration procedure for the
new linear output.
Low-drift, highly stable circuitry ensures years of reliable and accurate
temperature control. The recommended two year re-calibration interval is easily
accomplished via the programming menu.
Programmable output power limits provide protection for processes where
excessive power can cause damage. Automatic sensor probe break detection,
for fail-safe operation, causes the controller to default to a programmed output
power (upscale or downscale burnout). 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 outputs, there are up to three types of ON/OFF
outputs.These outputs can be relay, logic, or triac for control or alarm purposes.
Relay outputs can switch user applied AC or DC voltages. Logic/SSR drive
outputs supply power to external SSR power units. One Logic/SSR Drive output
can control up to four SSR power units at one time. The Triac output supplies
one Amp of AC current for control of an external AC relay or triac device.
AUTO-TUNE
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.
The T48 has an auto-tune feature which, on demand, automatically
determines the PID control parameters for a particular thermal 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 Communications
HEATER CURRENT MONITOR
The T48 provides a direct readout of process heater current. This provides
valuable information regarding single phase heater system integrity. It is
especially useful on extruder and large oven applications where adjacent
controllers mask the effect of a failed heater. The heater break alarm senses two
types of heater system faults:
1) Main control output is “on” and heater current is below alarm value. This
indicates failed heater or failed parts of heater, breaker trip, failed power
control device, etc.
2) Main control output is “off” and heater current is above 10% of alarm value.
This indicates a failed power control device, wiring fault, etc.
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 T48 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.
HEATING AND COOLING SYSTEMS
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 transmission of
temperature or setpoint values.
The T48 is available with dual outputs to provide heating and cooling to those
processes that require them. For example, many extruder applications require
both heating and cooling to maintain accurate extruder barrel and die
temperatures. The T48 is easily configured for these types of applications.

CONFIGURATION PARAMETER MODE
The Configuration Parameter Mode allows the operator to set-up the basic
requirements of the controller. It is divided into sections which group together
related programming steps, such as inputs, outputs, alarms, etc. Upon completion
of each section, the program returns to the Configuration Access Point, allowing
the user to return to the Normal Display Mode.
