Multiple Receiver Installation
An advantage of the standard 4-20 mA DC output signal produced by the
Series 616 Transmitter is that any number of receivers can be connected
in series in the current loop. Thus, an A-701 Digital Readout, an analog
panel meter, a chart recorder, process controlling equipment or any
combination of these devices can be operated simultaneously. The only
requirement is that each component be equipped for a standard 4-20 mA
input and the proper polarity of the input connections be observed when
inserting the device in the current loop. If any of the units display a
negative or downscale reading, the signal input leads are reversed.
Maintenance
Upon final installation of the Series 616 Differential Pressure Transmitter
and the companion receiver, including the A-701 Digital Readout, no
routine maintenance is required. A periodic check of the system
calibration is recommended following the procedures explained on page
3 under Calibration Check. The Series 616 Transmitter is not field
serviceable and should be returned, freight prepaid, to the factory if
repair is required. Please enclose a description of the problems
encountered plus any available application information. The A-701
should be returned directly to its manufacturer for service. See the A-701
instructions for address.
