Bus control: Bus control is normally selected. For equipment which also uses a standard hard-
wired system, this configuration allows the user to chose the command mode: either via bus
or hard-wired (see §7.1 and §7.2)
Slave no. Actuator address. All actuators have to have different addresses.
The default address is 2.

28 USING IN CASE OF POWER SUPPLY LOST (WITH BATTERY DEPENDING
ON MODEL)
Depending on the actuator model, the battery option allows to display the position when the power
supply is off. When the power supply is off, the actuator goes into standby mode with very low
power consumption.
Regular tests allow to check the valve position, if the position changed the relays are updated.
- In case of actuator with position feedback the position
is updated.
- In case of fieldbus communication, the fieldbus board
is supplied (5s) to allow the PLC bus controller to read
the new position.
When the power supply is off the display can be read but it cannot possible to navigate into the menu.
To wake up the system and illuminate the display, you must act on the command button blue
as to give an order to close. The “low battery” information can be read at any time on the display
or by remote signalling. The display will be shut down after 30 secondes without activity.
- Temperature: 40°C (For different temperatures (above or below) the life expectancy may be reduced)
Note: even without the battery the
actuator operates without risk
of loss or configuration of its position
