2.5 Sensor Shutter Function Check

Temporarily connect an air supply — (90-95 PSIG (6.2-6.55 bar) [620-655 kPa];
110 PSIG (7.6 bar) [760 kPa] maximum) — to the actuator air line and test
operation (10-15 cycles). When actuated, shutter movement should be smooth,
rapid, and complete, and should contract completely from the crystal opening.
When deactivated, the shutter should completely cover the crystal opening. If
operation is impaired, lubricate the moving parts, in areas specified on

, with molybdenumdisulfide or its equivalent. If the function check

was successful, make appropriate pneumatic, water, and coax cable connections
using a suitable feedthrough assembly. Consult

section 4.5 on page 4-5

for

information regarding maintenance of the sensor shutter.

WARNING

Do not exceed the maximum pressure rating of 110 PSIG
(7.6 bar) [760 kPa]. Connection to excessive pressure
may result in personal injury or equipment damage.
