Actuator Installation
If installing an actuator on an existing standard single or dual sensor, the actuator front
face should align as shown with the sensor body. (See
sensor shutter on existing equipment requires either a Single Shutter Assembly (PN
784-209-G1) or a Dual Shutter Assembly (PN 784-210-G1).

1
If replacing an actuator assembly, remove the failed assembly.
2
Place the actuator clamp onto the actuator using the grooves on the actuator to
center the clamp.
3
Rotate the shutter module until the holes through the actuator assembly of the
shutter module coincide with the #4-40 tapped holes in the rear side of the standard
crystal sensor assembly.
4
Secure the shutter module to the standard crystal sensor assembly utilizing the
#4-40 hardware provided with the shutter assembly.
5
Position the shutter directly over the center of the crystal opening. Tighten the shutter
cap screw. Make certain the shutter, when activated, does not block deposition of the
evaporant stream onto any portion of the crystal.
In-Vacuum Cable
In-vacuum microdot cable connectors should be hand tightened
only
. To remove the
in-vacuum cable, hold the sensor body microdot connector in place using the flat sides
of the connector, prior to attempting to loosen the in-vacuum cable.
WARNING
If the microdot connector is not held or clamped in place, prior
to removing the microdot cable, the sensor may be damaged.
