WARNING
Electrical Consideration / Precautions
The controller is considered “rack and panel mounted equipment” per EN 61010-1, Safety Requirements for
electrical equipment for Measurement, Control and Laboratory Use, Part 1: General Requirements. Conformity
with 2/23/EEC Low Voltage Directive, requires the user to provide adequate protection against a shock hazard.
The user shall install this controller in an enclosure that prevents OPERATOR access to the rear terminals.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN DEATH OR SERIOUS INJURY.
Shielded twisted pair cable is required for all Analog Input & Output, Process Variables,
RTD, Thermocouple, DC volts-mV, low level signal, mA, Alarm Outputs, and Computer
communication interface circuits.
CAUTION
FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PRODUCT DAMAGE.
Power Supply / Wiring Requirements
Applying 240V AC to a controller rated for 12-24VDC will severely damage the controller
and is a fire and smoke hazard.
This controller is suitable for connection to 12 / 24 VDC, power mains.
It is the user responsibility to provide the following
12 / 24 VDC – a switch, fuse (1A, 125A) or a circuit breaker.
The above items should be installed together with UT-1405 for the products electrical protection.
The switch, Fuse or circuit-breaker should be located close to the controller, within easy reach
operator. The switch or Circuit-breaker should be marked as the disconnecting device for the
controller. applying power to Multiple instruments, make sure that sufficient current is supplied,
Otherwise, the instruments may not start up normally due to the voltage drop caused by the in-
rush current.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PRODUCT DAMAGE.
Disposal action of Instruments follows as per country and regional law and rules & regulation also same in
international. Company might be follows as per rules.

Function
Mount Anywhere
Various different configuration levels provide easy access to parameters. There are 4 digit security code
perverts unauthorized changes. Parameters can also be hidden to user to prevent improper configuration
of the unit. There are 4 keys provided for easy configuration and setup.
The UT-1405 product group is Clean Room instruments that must be Flush or Wall mounted. The wiring
terminals must be provided. the UT-1405 is environmentally hardened and, if suitably handled, can be
mounted virtually anywhere in clean room or enclosure wall mounted or Flameproof enclosure or even on
the AHU or Technical Area.

NOTE : All Dimensions are in mm
The UNITECH's “Clean Room Indicator(T+DP) [UT-1405]” has been specially developed keeping process
measurement requirements of Clean rooms parameters like Temperature & DIFF. PRESS. in Pharmaceutical
industries. The Process Monitor can measure these parameters through inbuilt sensors. The Monitor has
LEDs for Alarms. Temp. and DP will display individually and data transfers to any master device on Modbus
RS-485 communication. It also has communication diagnosis LED. The monitor has inbuilt buzzer for audible
Alarm. It has keypad to programming the instrument by end user. It has Stainless steel Modular Face plate,
which is designed as a mounting accessory for monitor suited for Modular wall Clean Room applications
where you need flush mounting mechanism. This instrument enables you to measure parameters.

5. COMMUNICATION [MODBUS RTU] PROTOCOL
5.1 Introduction
The unit can be connected in MODBUS/RTU communication data link protocol to messaging
structure, widely used to establish master - slave communications between devices. Each
device must have unique No. node address. Before starting any communication, choose a
baud rate compatible to the host device. A Modbus data sent from a master to slave tells the
selected slave what to do and what information to send back.
5.2 MODBUS Configuration Basic settings
The Basic settings for RS-485 Modbus protocol are as follows :
Band rate
