7.1.1 Control key switch
The control key switch is used to put the MCU in the following modes:
“Control” in this position the MCU is in the normal operational mode, automatically controlling
the ballast discharge system if automatic control is fitted.
“Off” in this position the display is blanked and the MCU goes to a quiescent state. Although
the MCU is in a quiescent state some inputs are still monitored and logged in the internal
memory.
NOTE:
Do not attempt to service the equipment in this mode, see section 8.
“Console” in this position the MCU is in normal operational mode but manual control of the
ballast discharge system is provided from the cargo console. There will be no alarms given
and some inputs are still monitored and logged in the internal memory.
