opening the failsafe actuator Installation
Configuration of the actuator nodes needs to be done by E3C to ensure all
parameters are as intended. We recommend that Eltorque Qualified Personnel are
present at commissioning of larger systems to ensure correct settings for all
nodes. See
section B.4.vii
for an overview of these parameters.
Before the actuator can be operated, the deep sleep state must be cleared. The
deep sleep state is cleared by connecting with E3C and the clear Service function.
The following section gives an overview of the different states the product can be
in and the way the state can be set.
Refer to Table 21 on page 70 for battery lifetime estimates for the different
states.
This is a non-operative state and the state needs to be cleared to have the
actuator enter an operative state. It is recommended to carefully reviewing table
8-21 before clearing this state.
Caution!
The interface and failsafe module will after disassembly of the nuts still
hang on the stud bolts. Be aware not to lose the nuts.
