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.
