LI5X Process & Temperature Meter Instruction Manual

INTRODUCTION

The LI5X is a multipurpose, easy to use digital panel meter. It accepts

current, voltage, thermocouple, and RTD signals. The four front panel

buttons make the setup and programming an easy task.

The isolated 24 VDC transmitter power (optional) can be used to power

the input transmitter, the 4-20 mA output, or other devices.

The two relays (optional) can be used for alarm indication or process con-

trol applications, such as pump alternation control.

The 4-20 mA isolated output and the Modbus RTU serial communication

options make the LI5X an excellent addition to any system.

ELECTRICAL

NOISE

SUPPRESSION

A suppressor (snubber) should be connected to each relay

contact switching inductive loads, to prevent

disruption to the microprocessor’s operation.

Recommended suppressor value: 0.01 µF/470 Ω, 250 VAC

HIGH OR LOW

ALARM

User may program any alarm for high or low trip point.

RELAY

OPERATION

Automatic (non-latching)

Latching

Pump alternation control

RELAY RESET User selectable via front panel buttons or PC

Automatic reset only (non-latching)

Automatic + manual reset at any time (non-latching)

Manual reset only, at any time (latching)

Manual reset only after alarm condition has cleared (latching)

Automatic reset: Relays will automatically reset when the

input passes the reset point.

Manual reset: Front panel ACK button. Pressing ACK re-

sets all manually resettable relays.

TIME DELAY 0 to 199 seconds, on and off delays

Programmable and independent for each relay

FAIL-SAFE

OPERATION

Programmable

Independent for each relay

AUTO

INITIALIZATION

When power is applied to the meter, relays will reflect the

state of the input to the meter.

Fail-safe operation: relay coil is energized in non-alarm condition. In

case of power failure, relay will go to alarm state.
