Air Measuring Station Pressure Transducer
The rooftop unit provides for a ventilation mode that
can use the optional Air Measuring Station. When us-
ing the optional Air Measuring Station, either one or
two identical pressure transducers are employed. When
using the Minimum AMS or the ¼ - ¾ AMS, two trans-
duc ers are used. Only one transducer is used with the
Full AMS. In any case, the locations of the transducers
are in the return air section mounted on a panel. Both
the pneumatic tubing and control wiring are factory
in stalled. The transducer range is 0 to .25 iwg with an
output range in volts DC as shown in Table 25.

Discharge Pressure Transducer
The optional discharge pressure transducer is located
in common discharge line of the tandem compressors
for each refrigerant circuit. The purpose of this trans-
duc er is to sense and convert the discharge pressure
to a DC voltage. The DC voltage is then sent to the
unit controller where it can control head pressure (with
op tion al low ambient kit), provide compressor unload-
ing, and display discharge pressure on the OptiLogic
dis play panel. The transducer and wiring are factory
in stalled. Whenever an optional transducer package is
supplied, the transducer is wired to a factory supplied
