Remove the packing list and verify that all equipment has been received. If there are any questions about the shipment, please call OMEGA Customer Service Department at 1-800-6222378 or (203) 359-1660.

Upon receipt of the shipment, inspect the container and equipment for any signs of damage. Take particular note of any evidence of rough handling in transit. Immediately report any damage to the shipping agent.

NOTENOTE

NOTE The carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removing contents, save packing material and carton in the event reshipment is necessary.

Mount the instrument in a location that will not be subject to excessiv e temperature , shoc k , or vibr ation. All models are designed for mounting in an enclosed panel.

Select the position desired for the instr ument on the panel. If more than one instr ument is required, only two units can be mounted closely together, either one above the other or side b y side . When mounted together, the mounting collar will require modification b y removing the inside tab from each collar.

Prepare the panel by cutting and deb urr ing the required opening. From the front of the panel, slide the hous-

ing through the cut out. The housing gaske t should be against the housing flange before installing.

From the rear of the panel slide the mounting collar o ver the housing. Hold the housing with one hand and using the other hand, push the collar e venly against the panel until the spr ing loops are slightly compressed. The ratchets will hold the mounting collar and housing in place.

INPUT SELECTION

To change the input type, remove the instrument from its housing. Grasp the front bezel sides and pull forward to release it from the housing lock. Locate the dip switch on the right pcb. Determine the input type desired and change the dip switch setting as shown to the right.

NOTE : NOTE :

NOTE : Factory default is set for thermocouple inputs.

After changing input selection with the DIP switches, be sure to change the InP menu item (page 9) in the Secure Menu.

NOTE:NOTE:

NOTE: InP menu item factory default is set for type "J" thermocouple, Iron/Constantan

Scaling for thermocouple and RTD inputs is fixed for each range type. See page 8 for scale ends.

Scaling for current and voltage inputs is field adjustable by using SCAL and SCAH in the Secure menu. Program SCAL to the low end value of your transmitter. Program SCAH to the high end value of your transmitter. If the span of your transmitter is less than 100 units (referred to as 'counts' in these instructions), multiply the transmitter span by 10 and change the decimal point position in menu item dP.

For example, if you have a differential pressure transmitter with a range of -0.25 to +0.25 inches of water. SCAL would be programmed to -250, SCAH to +250, and dP to 0.000.

Star t the process and wa it f or it to come to stability. Occasionally check that the Self Tune has completed the lear ning process by INDEXing to Str t in the secondar y menu . If the YES value has changed to no, then the process has been learned. Once lear ning is complete, you may adjust SP2 to either over lap the SP1 band (SP2 value less than z ero), or add some separation betw een them (deadband — SP2 greater than z ero) if required to optimize control.

value at which the alar m is to occur. When setting the alar m value f or a de viation alar m ( ALt = dE), set the alar m to the v alue

equal to the diff erence in v alue betw een the desired alar m and Set Point 1. F or example if a lo w alar m is required to be 5 degrees below SP1, then set ALLo to -5. If a high alar m is required 20 degrees abo ve SP1, then set ALHi to +20. If SP1 is changed, the alar m will continue to hold the same relationship as or iginally set.

The following diag ram show s the action and reset functions for both absolute and de viation alarms.

When “Alar m P o w er Interr upt” ALPi is programmed ON and “Alar m Reset” is prog rammed for Hold, the alarm will automatically reset upon a po w e r failure and subsequent restor ation if no alar m condition is present.

If “Alar m Inhibit” ALiH is selected ON, an alar m condition is suspended upon pow er up until

the process value passes through the alar m set point once. Alar m inhibit can

The simplest example is an output of 0 to 10 VDC from 0 to 200°. In this example POL=0 and POH=200. To Calculate POL and POH for other ranges use the following: K = (Highest desired temperature - Lowest desired temperature) /

(Maximum desired voltage - Minimum desired voltage)

POH = ((10 - Maximum desired voltage) * K) + Highest desired temperature POL = ((Minimum desired voltage - 0) * K) - Lowest desired temperature
