Customizing Fault Relay; Timing Movement Travel - Bernard Controls SQX Série Manuel De Mise En Service

Some of the selections have further options, see next page;
(1) (from x% to y%)
Specify contact action range after turning to OK to confirm:
Select x% and turn to OK to confirm.
Use the blue selector to increase or decrease the value.
Select y% and turn to OK to confirm.
Use the blue selector to increase or decrease the value. Turn to
OK to confirm.
(running)
(2)
(opening)
(closing)
Turn to OK to confirm and then specify whether
status to be steady or flashing indication. Turn to OK to confirm.
(3) (bus command)
This function is only applicable if the fieldbus option is active.
In this case, this relay can be used to control a device located
outside the actuator, with commands transmitted from the control room via the fieldbus and then
forwarded via the actuator (refer to documentation relating to bus).

20 CUSTOMIZING FAULT RELAY

Fault signals are sent via a changeover relay which is normally energised and returns to the break
position if power is lost or if the actuator is unavailable.
This relay can be configured applying a list of options.
The equipment is configured at the factory in accordance with
the order. Changes can be made as follows:
Select change in the MENU and turn to OK to confirm
Select signaling in the CHANGE menu and turn to OK to confirm.
Select remote in the SIGNALING menu and turn to OK to confirm.
Select fault relay in the SIGNALING menu and turn to OK to confirm.
Including additional faults
Included faults which cannot be altered are shown without brackets. Options are in brackets and selec-
tions are shown with an asterisk *.
Turn to OK again to cancel selection.

21 TIMING MOVEMENT TRAVEL

INTELLI+ includes a timing module for reducing the actuator's operating speed (for example to protect
a line against pressure surges).
The timing system applies a series of on / off commands to the motor when an open or close command
is transmitted. The time spent operating the valve can be very long. Times can be adjusted in situ.
Settings for the opening and closing directions are separate.
It is also possible to apply timing to just a section of the stroke, with the remainder being completed
at normal speed.
The user just has to specify the total time required for the movement and INTELLI+ calculates
on and off times.
Select change in the MENU and turn to OK to confirm .
Select timer in the CHANGE menu and turn to OK to confirm.
Select timer open time and turn to OK to confirm.
Indicate the total time in which you want to open the valve
and turn to OK to confirm.
Select timer close time and turn to OK to confirm.
Indicate the total time in which you want to close the valve
and turn to OK to confirm.
To cancel the time function: check to ensure timer opening
and closing times are not higher than operating time (Value indi-
cated in the 'data sheet' menu..
To apply timing to one part of travel only:
select temporised zone and turn to OK to confirm.
To start opening timer from a specific position,
select open: start % and turn to OK to confirm.
Use the blue selector to increase or decrease the value until you
obtain the required position between 0 and 100% and then turn
to OK to confirm.
Do the same for the other values to establish a timer-controlled
opening zone and a timer-controlled closing zone.
Check default values when applying timer to entire stroke:
open: start % (0) close: start %
open: end % (100) close: end %
