User Manual QT series generation 2.5, ID 2021, rev 3.2, January 14, 2022
A battery test and maintenance plan must be implemented according to the
certification requirements or the class requirements (whichever is the
strictest). For the failsafe product, this implies that the battery must be
completely discharged regularly.
Battery discharge of lead-acid batteries must only take place while the ship
is at port, for example, during system revision shutdowns or as part of ship
maintenance routines. It implies that the actuator is non-operational during
this procedure. The discharge routine may take up to 24 hours, depending
on the battery status when the routine is started.
Reference is made to the
System Integrators Manual CANopen Interface
for
the correct register/index.
1.
Set the actuator in service mode.
2.
Send the command “Start Battery Deep Cycle Test”
3.
The actuator automatically charges the battery to 100%.
4.
The bit “BATTDIS” indicates that the test is performed.
5.
When the battery reaches 0%,
the “BATTDIS” is automatically cleared,
the SOH value is updated, and the battery is recharged.
6.
When the battery has reached the lower limit for SOC, service mode
can be cleared, and the actuator resumes normal operation.
This procedure describes how to change the battery in the failsafe module.
Parts of this procedure also applies to first time installation the Failsafe
actuator as the battery cable must be connected - see steps 12

Description
Illustration
1
Enable service mode either from the actuator control panel, or by rotating the
handwheel of the actuator.
Make sure that the actuator service indicator light is yellow on all actuators that the
battery change procedure is going to be performed on before proceeding to the next
step.
2
Turn off the power going to all actuators that the battery change procedure is going to
be performed on. (Be aware of failsafe triggers for the rest of the loop.)
