C. Stroke Times
For stroke times of the Access I Series 39 actuator with solenoid
and control block, consult factory. Times will be measured in
seconds and will represent average times under 50% load
conditions with an air supply pressure of 80 psig. Times will be
per stroke for double-acting actuators. For spring-return actuators,
the opening stroke times may be slightly longer; stroke times for
the closing (spring) stroke will be dependent upon the number of
springs used. Cycle times for customer air supply systems will be
dependent upon customer equipment.
D. Manual Operation
In the event of air failure, the Access I Series 39 actuator can be
cycled manually. This is accomplished by applying a wrench to
the exposed top shaft of the actuator and turning it in the
desired direction.
a WARNING: Care must be taken to ensure that the actuator
is not operated automatically while manual operation is
being performed.
If a routine cycle check is to be performed on an actuator with a
control block, the actuator can be cycled manually by shifting the
spool valve within the control block. This can be done by
pushing the override button in the control block (see figure
below for location of button). Care must be taken to hold the
spool valve in the desired position until the actuator has cycled.
Provided the air supply is still on, the actuator will cycle to its
original position as soon as the manually applied pressure on the
override button is released.
MAINTENANCE
CAUTION: The actuator must be isolated both pneumatically and
electrically before any maintenance activity is begun.
Periodic checks should be performed to make certain that all
fasteners remain tight. Care should be taken when tightening the end
cap retaining bolts since these fasteners are METRIC. All other
fasteners are UNIFIED IMPERIAL.
All actuators are supplied with sufficient lubrication for their normal
working life. If required, recommended lubrication for all standard
actuators is a #1 grease.
Depending upon the conditions under which the actuator must work,
such as extended duty, non-compatible operating media or abnormal
operating conditions, periodic replacement of internal seals is
recommended. Repair kits containing all necessary seals can be
obtained through any authorized Worcester/McCANNA distributor.
On spring-return actuators, the springs may need replacement after
extended duty since springs may fatigue and break. SPRINGS
SHOULD ALWAYS BE REPLACED IN COMPLETE SETS. Spring kits are
available through any authorized Worcester/McCANNA distributor.
SPARE PARTS
The following are recommended spare parts which should be kept on
hand for Series 39 pneumatic actuators:
Repair Kit(s) – Kits contain all necessary seals, bearings and
instructions.
Spring Kit(s) – For Spring-Return Actuators.
