GENERAL DESCRIPTION

The TLA is a Factory Mutual approved temperature limit alarm, intended to

provide an independent shutdown for thermal processes. The TLA accepts

signals from a variety of temperature sensors (thermocouple or RTD elements),

and its comprehensive programming allows it to meet a wide variety of

application requirements.

Dual 4-digit displays allow viewing of the process temperature and limit

setpoint simultaneously. Front panel indicators inform the operator of the

process and output status. The main limit output and alarm outputs are field

replaceable.

The limit output is selectable for high or low trip activation. If the process

temperature goes above the limit setpoint for a high trip, or below the limit

setpoint for a low trip, the limit relay will de-energize to initiate a process

shutdown. The limit output cannot be reset until the process temperature returns

to the proper operating range; manual reset is required (local or remote). Sensor

failure will initiate a process shutdown.

Relay 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 adjustable

hysteresis. A standby feature suppresses the alarm during power-up until the

process stabilizes outside the alarm region.

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 TLA 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 TLA 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.
