SIL
Under normal operating conditions the COMPACT SY actuator should be inspected for proper functioning and
signs of deterioration every 50,000 cycles or 6 months (whichever comes first). Under severe operating
conditions inspection should be more frequent; detected defects should be repaired promptly.
Severe operating conditions can be defined as:
•Application temperature less than -20 °C (-4 °F)
•Application temperature higher than +80 °C (+176 °F) for standard applications
•Application temperature higher than +110 °C (+230 °F) for HT applications
Habonim recommends a proof test interval of 12 months; in case of Fail to Open ESD system, a partial stroke is
acceptable to confirm that the installation is functioning properly.
For ESD systems with a Fail-To-Close demand, it is necessary to plan a system shut-down; de-energize the
system and inspect the actuator turning to its fully closed position.
It is essential to log-in the following parameters on site QA records as a proof for preserving SIL capabilities:
date, hour, name and signature of the responsible engineer, air pressure on site, time to close the valve, time to
open the valve.
Habonim recommends actuator full maintenance operation every 500,000 cycles or 4 years, whichever comes
first (refer to clause 6 in this IOM for maintenance instructions). The combined corrosion and erosion allowance
for the actuator’s body wall thickness is 1 mm. When this allowance has been eroded or corroded, mechanically
removed or otherwise, the actuator should no longer be used. Inspect the actuator’s wall thickness every time
the actuator is maintained.
Maintenance team must read and understand the Habonim product IOM before starting the operation. In case
of a doubt please consult the Habonim engineering team.
When an actuator has been repaired or any maintenance was performed, check the actuator for proper
function (proof testing). Any failures affecting functional safety should be reported to the Habonim factory.
Client should consult the Habonim factory in order to obtain the product assessment, FMEDA report, and other
associated statistical data to satisfy SIL level.

Storage
The Compact SY actuator has been packaged to provide protection during shipment, however, it can be
damaged in transportation. Prior to storage, inspect the actuator for shipping damage. Keep the actuators in
their original packing box during storage. It is recommended to keep the actuators in a clean and dry
environment until ready for use. The actuator has two air ports, which should be plugged during storage to
prevent liquids or other materials from entering the actuator during storage. If the actuators are to be stored
for a long period of time before installation, it is recommended to cycle them periodically to prevent setting of
the seals. Store the actuators indoors to protect them from humidity and dust.
