Mounting the Positioner

CAUTION: Positioner shaft is spring-loaded and

features mechanical stops at each end of stroke.

Failure to follow these procedures carefully may

result in severe damage to positioner. Read through

entire procedure before starting.

1. Attach positioner mounting bracket to actuator using

fasteners supplied with bracket (Figure 4). Tighten

bolts finger-tight only at this time.

2. Install coupler (if required – coupler is not required

for NAMUR mounting) on actuator shaft, making sure

it is centered.
