Chapter 1 Introduction
Introduction
The Uni-Tran micro-controller based toxic gas detector provides fast, accurate, continuous and cost effective
monitoring of toxic gases in harsh industrial environments.
Net Safety selects the very best electrochemical sensors from the world's leading manufacturers for use in its broad
line of toxic gas detectors. High performance, proprietary circuits and micro-controller based firmware ensure
accurate and repeatable response in the most severe environments and a reduced need for routine calibrations.
The Uni-Tran control module uses advanced micro-controller technology to provide a user interface that is
comprehensive, yet very simple to use. The full text LED display gives the user complete instructions for routine
operation, calibration and relay configuration; without tools.
Features
< Electrochemical sensor technology
< Low power consumption that works with 12 or 24 Vdc systems
< Easy, non-intrusive one person calibration
< Sensor can be remotely mounted up to 75 feet from the display module
< Scrolling alpha-numeric LED display available in English, French or Spanish
< Gas specific colour coded enclosure
< Microprocessor based smart transmitter
< Conformal coated circuit boards

Chapter 2 Installation and Start Up
What’s in the package
Carefully remove all the components from the packing box(s). Check components against the packing list.
Inspect all components for obvious damage and broken/loose parts. Notify the carrier and distributor
immediately if damage is found or parts are missing.
Location of Sensor(s)
There are no absolute rules for determining the quantity and location of gas detection instruments within a
particular facility. Care should be taken to locate the sensors in areas where gas escape may be expected and
where it is desirable to detect the presence of unwanted gas. Use redundancy where enhanced protection or
reliability is desired. Heavy gases such as H S, CO and SO tend to accumulate in low areas. Seek advice from
experts who know the characteristics of the gas being detected, air movement patterns and the facility. Use
common sense and refer to various publications that discuss general guidelines for your industry.
Unpacking
The UNI-TRAN Premium Plus is made up of two primary components (refer to figure 1). The Enclosure and
relay board are a single assembly to which the sensor is wired. The control module (CPU board / display
board) is a separate plug-in assembly. First, remove the sensor from the white shipping container (not
applicable to ST1210) Remove the lower half of the Sensor Housing by unscrewing it counter clockwise. Plug
the sensor into the upper half of the Sensor Housing. Replace the lower Sensor Housing and tighten the
housing.

WARNING:
Do not attempt to unscrew the “knurled” pull knob. Do not separate the CPU board and
Display board.
NOTE:
Since all modern electronic equipment can be damaged by static electricity discharge, it is
important to take precautions. Discharge static electricity from your body by touching a
grounded metal object before handling the module.
Remove the control module from the housing, by grasping the centre “pull” knob and pulling straight away,
then temporarily store the control module in a clean safe place until after the field wiring has been connected
to the terminal strip located on the relay board.

Mounting
The housing should be oriented so that the sensor is on the underside of the housing. Water will damage
electronic devices. Seal conduit near housing entries to prevent water damage in the enclosure (refer to figure
2, 3, 4 and 5).

Wiring
(refer to figure 7, 8, 9, 10, 11 and 12)
NOTE:
The wiring procedures in this manual are intended to ensure proper functioning of the device
under normal conditions. However, because of the many variations in wiring codes and
regulations, total compliance to these ordinances cannot be guaranteed. Confirm that all
wiring complies with applicable regulations that relate to the installation of electrical
equipment in a hazardous area. If in doubt, consult a qualified official before wiring the
system.
NOTE
The control module (CPU board and Display Board) with cable should never be totally removed
from the Relay board and housing. If it is removed there are bright red alignment markings on the
cable and on the Relay board for you to use when re-inserting the cable into the Relay Board
connector.
NOTE
Since all modern electronic equipment can be damaged by static electricity discharge it is
important to discharge static electricity from your body by touching a grounded metal object before
handling the module.
Refer to figure 1
The transmitter is made up of two assemblies. The enclosure / relay board are a single assembly to which the
input is wired. The control module (CPU board and Display Board) is a separate assembly. To conduct wiring
unscrew the two retaining screws from the front of the display board . (The control module is attached to the
relay board by a cable. Do not detach the cable during wiring). Detach the module from the housing by
grasping the centre (Pull Here) knob and pull straight away. Gently hang the module from the cable while you
conduct wiring.
The use of shielded cable is highly recommended for signal, input, output and power wires to protect against
interference caused by extraneous electrical 'noise'. Relay outputs do not require shielded cable. In
applications where the wiring cable is installed in conduit, the conduit must not be used for wiring to other
electrical equipment. The maximum distance between the sensor and controller is limited by the resistance of
the connecting wiring, which is a function of the gauge of the wire being used. Refer to the manuals on the
sensors used (and transmitters if used) for maximum wiring distances and wiring instructions (refer to
Appendix B).
NOTE:
The controller contains semiconductor devices that are susceptible to damage by electrostatic
discharge. An electrostatic charge can build up on the skin and discharge when an object is
touched. Therefore, use caution when handling, taking care not to touch the terminals or
electronic components. For more information on proper handling, refer to the Appendix A.
Water-proof and explosion-proof conduit seals are recommended to prevent water accumulation within the
enclosure. Seals should be located as close to the device as possible and not more than 18 inches (46 cm)
away. Explosion-proof installations may require an additional seal where conduit enters a
