The failsafe module introduces changes to the overall actuator appearance
and function. The following limitations are important to consider during
planning.
• Certified temperature location class is reduced from class D to class A
when the option failsafe is selected.
• The actuator's overall size is increased, see section 11.3.6 Space
requirements on page 67.
• A battery maintenance plan must be established to ensure that the
battery has enough energy to perform the required task(s) and that the
battery SOH is within acceptable levels. See section 11.8 Maintenance on
page 74.
• Storage conditions and charging of batteries in storage. If the actuator
and or battery is not installed and externally powered within a
reasonable time after the reception, a storage and or charging plan
needs to be established. Please refer to section 11.3.5 Storage on page
67.
Note! If the intended storage time is longer than 3 months after reception, please
refer to section 11.3.5 for input on proper storage conditions.
It is important to consider the information below when planning the
installation of the failsafe actuators. Due to it being a solution with a
battery, it cannot sit without external power for an unlimited time due to
self-draining. See Table 11: Battery lifetime below for details on expected
battery lifetime. It is important to both select an installation strategy for the
actuators, and to respect the battery lifetime estimates during the
installation.
Based on this information, Eltorque has made the following input on how
the products can be handled from reception to fully commissioned.
The actuator is shipped with the battery installed in the module, but without
the battery connected to the UPS management card. When received one can
choose between installation method A or B. Installation method A can be
installed in either way 1 or 2.
A. Install the actuator with the battery mounted in the module of the
installed product. This installation method can be divided into two
options:
Caution! Battery warranty may be voided if the battery is damaged and there is no
installation plan available
