RESERVE POWER PACK - (OPTIONAL)
The actuator can be fitted with an optional ‘Reserve Power
Pack’ consisting of Super Capacitors to allow the actuator to
go to a pre-determined position on power failure.
On power up the super capacitors require a charging period
during which time the actuator electrical operation will be
inhibited. This could take up to two minutes.
NOTE: Electrical operation is inhibited and the LED will
flash during the charging period.
On loss of power supply the actuator will carry out
its designated failsafe function. The LED remains
illuminated until the energy stored in the capacitors
has depleted.
WARNING
Where actuators are supplied with the reserve Power
Pack Assembly please note that the actuator output shaft
may move after removal of the power supply.
Move the Knob Selector to the ‘STOP’ position to prevent
any unwanted electrical movement before carrying out
any maintenance or removal of the unit from the valve.
After disconnection of the actuator power supply wait
until the LED indicator on the top cover assembly has
extinguished before attempting to remove the actuator
from the valve. Under no circumstances attempt to
remove the actuator or adjust the output drive shaft
connection to the valve stem whilst the top cover LED
is illuminated.
The CVA main housing of the actuator and in particular
the power pack contain no user serviceable components
and the top cover assembly must be removed by suitably
qualified personnel only.
DO NOT REMOVE ANY COVER ASSEMBLY TO GAIN
ACCESS TO THE ELECTRICAL COMPARTMENTS WHILST THE
LED LOCATED ON THE SELECTOR KNOB IS ILLUMINATED.
