port is clear. Do not mount the transducer in a
location where foreign material may cover the stroke
port. For information on using the stroke port, refer
to Section 5 – Troubleshooting.
Exhaust Port
The transducer exhausts through a screened port
located beneath the instrument nameplate. Figure
2-1 shows the location of the exhaust port. The
nameplate holds the screen in place. Exhaust will
occur with a reduction in output pressure. The
transducer should not be mounted in a location
where foreign material may clog the exhaust port.
Signal Interruption
Upon loss of input current, or if input current
decreases below 3.3
0.3 mA, the output of the
direct action unit will decrease to less than 0.1 bar
(1 psi).
In the same situation, the output of the reverse
action unit will increase to near supply pressure.
