3.1. Inspection Items and Cycle

 

The inspection must be performed to maintain a high performance when the positioner is to be operated for a long duration.

Inspections are divided into daily and regular inspections, and the personnel responsible for inspections must carry out inspections according to the basic inspection cycles, as shown in [Table 3-1].

The overhaul should be carried out every 20,000 operating hours.

 

It is required to refer to the following items. If the inspection and adjustment methods are difficult to understand, please contact our after-sales service center (customer support department) for inquiries.
