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 §6.1 and §6.2)
Slave no. Actuator address. All actuators have to have different addresses.
The default address is 2.
Refer to specific documentation for further details on fieldbus interfaces commissionning.
30 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.
- Battery estimated life time in the actuators:
1/3 of time in storage or without power supply (Includes display of 20 s / day during this period)
2/3 of time with power supply
- Temperature: 40°C (For different temperatures (above or below) the life expectancy may be reduced)
- Battery life time: 10 years.
31 ChANGING ThE DIRECTION OF ThE DISPLAY
In case of weatherproof version, the display and the buttons can be rotated each 90°.
Remove the cover of the display (4 screws) and or move the board in the desired position.
Replace the cover in order to put the buttons under the display.

Note: even without the battery the
actuator operates without risk
of loss or configuration of its position
32 FUSE PROTECTION
The INTELLI+ power supply system includes a transformer and a number of fuses.
Primary: 6.3x32 mm - 0.5 A - quick-action fuse (located on the transformer).
Secondary: Internal circuits protected by automatic cut-out (no user action needed) 24V auxiliary
power supply on terminal protected by automatic cut-out (no user action needed)
33 USING IN SEPARATED bOx (OPTION)
INTELLI+ can be provided in separated box to be removed from the actuato up to 50 meters.
BERNARD CONTROLS provides weather proof boxes with two weather proof connection boxes:
one to be used by the customer, the other to be used to connect INTELLI+ to the actuator.
Explosion proof version is also available.
To plan a power wire and a control wire between the actuator and the box. The control wire must
be armoured. Check the wiring before powering up.
The commissioning is the same as the integrated INTELLI+.
34 MAINTENANCE
ST actuators have life-long lubrication and there need no specific maintenance.
However, the condition of the stem and the stem nut should be checked periodically to ensure
that they are clean and properly lubricated.
We recommend establishing a regular programme of test movements on motor drive units which
are rarely used.
In the case of the actuator with the battery option
Depending on the actuator configuration, a «Low Battery» message appears on the display
or remotely when the battery is too low.
You must replace the batteries by this type of battery:
2 batteries OMNICEL ER14505HD Lithium Thionyl Chloride (Li-SOCl2) type.
Other possibilities : MICROBAT ER14505 M or EVE ER14505 M.
For weather-proof SQ ST actuator, you should also choose another type with this requirement:
AA, 2.2Ah, 3.6V, 400mA, -40°/+85°C.
