MODEL UM330
Digital Indicator with Alarms

GS 05F01D02-02E

■General

Model UM330 Digital Indicator with Alarms is a precision
alarm instrument with universal input 1/8DIN. For
excellent monitoring operability, it displays process
variables on a large display. It is also provided with four
alarm setting points (or setting outputs; one is optional). A
retransmission output and 15 V DC loop power supply are
provided as standard. A communication fanction or 24 V
DC loop power supply is available optionally.

■Main Features

• Extra-large digital display allows the indicated values to be
read even from a long distance. LEDs of 20mm height are
used for the process variable display.

• Universal input allows simple setting of the input types
(TC, RTD, DCV) or input measuring range.

• Various communication function are provided.
Communication is possible with personal computer and
programable logic controller.

■Function Specifications

● Signal Computation Function

Measured input computation:

Contact input: Retains and displays maximum and

Bias addition (-100.0 to 100.0% of measured
input range width.), first-order lag filter (time
constant off, 1 to 120 s.)

minimum readings from measured variable.
Resets the maximum and minimum readings.

“E” indicates the
model with expanded
functions.

● Alarm Function

Six different types of alarms are provided. If an alarm
occurs, the alarm lamp indicates it. Four (one is optional) of
the six can be used as relay contact outputs.

Alarm types:

PV high limit, PV low limit, Deenergized on
PV high limit, Deenergized on PV low limit,
Fault diagnosis, and FAIL output

Setting ranges for process variable alarms:

PV alarms; -100.0 to 100.0% of measured input range.
Alarm hysteresis width; 0.0 to 100.0% of measured input

range width.

Delay timer:

0.00 to 99.59 (minute, second)
An alarm is output when the delay timer
expires after the alarm setpoint is reached.
Setting for each alarm is possible.

Fault diagnosis alarm: Input burn out, A/D conversion

error, TC RJC error
FAIL output: Software failure, hardware failure
Stand-by action:

Stand-by action can be set to make PV alarm
OFF during start-up.

● Display and Operation function

PV display:

Parameter display:

Status display: 4 alarm LEDs (AL1, AL2, AL3, AL4)
Operation keys: 쑶 and 쑴 keys: Increase/decrease

SET/ENT key: Sets setpoint data, calls or switches

4-digit digital display for engineering data

SELECT display:

Allows selection and registration of frequently
changed parameters from the operation
parameters during operation. For example, if
the first alarm setpoint is registered in the
SELECT display, the setpoint can easily be
displayed during operation.

Security function:

An operation inhibiting mode using a
password is provided.
