The SERIES 989A-12CA-MARR's input 2 was configured for a remote set point, output 3 was configured as a process retransmit, and event input 1 was configured to select the remote set point. The 982A-20A-MARR was configured with a linear input 1 scaled to match the process value on the 989A, while output 3 was set up as a retransmit of a set point.
The SERIES 982A's SPDT switch and operator, and a "local/remote" indicator were housed neatly in a ½ DIN x eight inch enclosure with a bail/handle and supplied with several tilt mount wall rackets. The 989A, the DIN-A-MITE, a DC supply for the 982A, and other accessories were housed in a NEMA enclosure near the process. The two enclosures were connected together by a 30 foot long cord using circular plastic connectors.
The customer was ale to locate the remote equipment on a mezzanine above the process. They were able to see the process temperature and change their process set point from either location by selecting "local/remote" at either end, saving many trips up and down the stairs.
