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 H2S, CO and SO2 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.
