5.2.3 Battery Test
Pressing will the move the valve position towards the close position by using the battery
power. A working battery will have 13V + in the cells, if this falls below 12.4V, there will not be
enough voltage in the battery to drive the valve to the closed position should a power failure occurs.
To test the battery operation, drive the valve to the closed position, then press . The valve
is then opened to the parked position using mains power, and then it is driven to the closed position
using the battery power to test the battery. If the battery cannot drive the valve to the closed position, a
24V fault will appear.
The bottom blowdown module is now commissioned, press and then proceed to commission
the water level probes, see section 2.3.1. After the M.M. has been commissioned for water level
probes and fuel-to-air ratio, the timings and intervals of the bottom blowdown can be set.
