Diagnostic Connections

To support diagnostic testing of valve/actuator/positioner/accessory packages, special connectors and hardware are
available. The hardware used includes 1/8 NPT connector bodies and body protectors. If the diagnostic connectors are
ordered for a positioner with gauges, 1/8‐inch stems are also included.
Install the connectors on the 3610J positioner gauge block or bypass block assembly as shown in figure 9. For 3620J
positioners, install the connectors on the 3622 housing as shown in figure 10. Before installing the connectors on the
positioner, apply sealant to the threads. Sealant is provided with the diagnostic connections and hardware.
