A MOV is a Metal Oxide Varistor and is used to protect against overvoltages; I don’t have the Z1 diagram so I cannot tell what its doing in the circuit- if you want to send the diagram to me (email add below) I can have a look at it.

Subject: Z diagram notations
I was looking at the old Z-1 Aeroelectric drawing and saw the notation “MOV” inside an oval box. Anybody know what that means and where the “notes” are for these drawings? Thank you. | Quote: | | http://www.matronics.com/Navigator?AeroElectric-List |

James,
This is a metal oxide varistor, used as a transient suppressor across an inductor. It has been determined that a diode works better for this task, so you will see diodes across the contactor coils in the later “Z” drawings.

Metal Oxide Varistor? Generally used for surge protection.

Your book is waaaayyyy out of date. Suggest you download the
latest Z-figures at:
http://aeroelectric.com/whatsnew.html
The MOV's were an early experiment that was supposed
to effectively tame the magnetic field collapse transient
in relay and contactor coils. It proved not be as efficient
and cost effective as the ordinary diode which you will
find featured in later drawings. In the current drawing
set, Z-1 is replaced by Z-11.
