PROPER SPEED SENSOR MODULE

 

MOUNTING

 

The LN-9 GMA Speed Sensor Module is a three lead

 

Hall-Effect switch device encased in an externally

 

threaded housing. It is screwed into a mounting plate

 

on the motor side of the wire drive gearbox. See

 

Figure D.1.

 

Proper positioning of this module is critical to operation

 

of the LN-9 GMA wire feed speed control. If the device

 

is not screwed in far enough, the LN-9 GMA motor

 

speed could be unstable or run at full speed with no

 

control. If screwed in too far it will rub a moving part

 

inside the gearbox.

 

The module is properly mounted to the gearbox as

 

shipped from the factory. If the device is ever removed

 

or replaced, proper mounting technique is as follows:

 

1. Be sure all power to the LN-9 GMA is shut off at the

 

power source.

 

2. Check that the module mounting plate is screwed

 

securely to the side of the gearbox and seated

 

flush against the top surface after being tightened.

 

3. Gently screw the module into the mounting plate

 

until it just touches and stops against the rotating

 

part inside the gearbox.

 

4. Back the module out 1/2 turn, then snug the mod-

 

ule locknut without rotating the module position.
