Preparing The Key Solenoid Rail - QRS Music Technologies QRS PNO3 Installation Manual

Preparing the Key Solenoid Rail
In this chapter, we determine the throw of the key solenoid plunger in rela on to the piano ac on's key‐tail travel.
We also walk through the process of key solenoid alignment with respect to the piano ac ons keytails. When this
chapter's work has been done, the solenoid rail will have the proper rail height and plunger throw. The moun ng
brackets will be in place and ready for moun ng to the piano.
Tools needed include the 2 op onal rail support brackets a 11/32" nut driver,
two rail bracket moun ng screws, screwdriver, hacksaw, metal file, ruler and a pencil. The piano ac on is on your
workbench and the keys are facing away from you.
The Pianoma on Key Solenoid Rail is shipped assembled.
Its component parts are as follows:
Lost Mo on Adjustment: Plunger‐Tip to Keytail Height
Don't confuse Lost Mo on with the Plunger Throw adjustment!
The Lost Mo on is the space between the ps of the plungers and the bo oms of the keytails.
Raise or lower the Key Solenoid Rail Assembly so that the plunger ps are as close as possible to the keytails
without touching.
