DESCRIPTION (Cont’d)
other process conditions. A control point may have its PID gain set values
disabled when implementing the control point.
The optional RS485 multidrop serial communications interface provides the
capability of two-way communication between a TSC unit and other compatible
equipment such as a printer, a programmable controller, or a host computer. In
multipoint applications the address number of each unit on the line can be
programmed from 0-99. Up to thirty-two units can be installed on a single pair
of wires. The Setpoint value, % Output Power, Setpoint Ramp Rate, etc. can be
interrogated or changed by sending the proper command code via serial
communications. Alarm output(s) may also be reset via the serial communications
interface option.
Optional alarm output(s) may be configured to operate as a timed event
output or as a standard alarm output. As an alarm output it may be configured to
activate according to a variety of actions (Absolute HI or LO, Deviation HI or
LO, or Band IN or OUT) with adjustable hysteresis. Also, a standby feature
suppresses the output(s) on power-up until the temperature stabilizes outside the
alarm region. Timed event output(s) allow the controller to activate other
equipment while a programmed profile is running. Each profile can define up to
16 event states (phases), for each output(s).
An optional secondary output is available for processes that require cooling
which provides increased control accuracy and response.
The optional linear 4 to 20 mA or 0 to 10 VDC output signal is available to
interface with final actuators, chart recorders, indicators, or other controllers. The
output signal can be digitally scaled and selected to transmit one of the following:
% Output Power
Measurement Value
Measurement Value Deviation
Setpoint Value
An optional Type 4X/IP65 rated bezel is available for washdown and/or dirty
environments, when properly installed. 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 TSC 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 unit. An independent and redundant
temperature limit indicator with alarm outputs is strongly recommended. The
indicators should have input sensors and AC power feeds independent from
other equipment.
