Checking the transducer lowering and hoisting functionality
During normal operation, the transducer is lowered and hoisted from the Operating Panel.
During this functional test, however, the operation is controlled from the Motor Control Unit.
Prerequisites
Before you can do this task, the
following prerequisites must be met:
• The MF90 system is turned off.
• The circuit breaker for the 3-phase
AC power is closed. AC power is
connected.
• The transducer is in its upper position
with the
Upper Limit Switch
(S304)
activated.
You must be equipped with a standard
set of tools. This tool set must comprise
the normal tools for electronic and
electromechanical tasks. Each tool
must be provided in various sizes.
We recommend that all tools are
demagnetized to protect your equipment.
Context
This task serves two purposes.
• You will verify that the transducer can be lowered and hoisted with local control.
• You will find the best way to secure the transducer cable so that it moves freely during
lowering and hoisting.
