Signalling - Bernard Controls INTEGRAL+ Manual Del Usario

By default, there is no priority given to either opening or closing.
Priority can be used to :
- Allow to reverse the actuator rotation direction during a manoeuvre without having to use the stop
command. In this case, it is necessary to set a priority to the opening or to the closing direction.
- Give priority to one or the other rotation direction : if the actuator receives the open and close
commands simultaneously and if the priority has been given to the opening, the actuator will run
the open position.
LOCAL CONTROL INHIBITED : allows to prevent any local command even if the actuator
local/remote selector button is on «local» position.
AUTO / ON-OFF MODE (positioner versions only) : allows to choose if the actuator has to work
in on-off mode (open or close) or in automatic mode (0-100% proportional positioning).
EMERGENCY COMMAND (ESD, Emergency Shut Down) : this command is hardwired (separate
wiring) and directly connected to the control box main terminal strip.
The ESD is a remote emergency command and has priority over any other command.
The ESD can be set to be an opening or a closing command (refer to NR1088).
To increase further the availability of the actuator in extreme situations, the ESD can also be set
to by-pass the motor thermal protection (refer to NR1088).
The ESD command inhibits any command received by the fieldbus. The ESD remains therefore
active even if the fieldbus communication is lost for any reason.

Signalling made available on the fieldbus are the same as the one delivered by the basic INTEGRAL+,
POSIGAM+ or MODUGAM+ controls.
Proportional position is only for actuator equipped with a positioner or a feedback potentiometer.

PHASE DETECTION : on the 3-phase actuators, the loss of 1 phase can be detected.
END OF TRAVEL - OPEN : activated by the open end of travel limit switch (actuator camblock).
END OF TRAVEL - CLOSED : activated by the closed end of travel limit switch (actuator camblock).
INDICATION RELAY 1 TO 4 :
The information transmitted depends on the INTEGRAL+ board configuration (refer to NR1088).
Configuration possibilities (sum-up) :
Relay 1 End of travel - open position
or Torque switch opening direction
Relay 2
End of travel - closed position
or Torque switch closing direction
Relay 3 End of travel - open position
or Torque switch opening direction
or Local/remote selector on 'local' position
or Local/remote selector on 'remote' position
or Actuator moving (electric motor manoeuvre)
or Actuator opening (electric motor manoeuvre)
Relay 4
End of travel - closed position
or Torque switch closing direction
or ESD command received
or Actuator closing (electric motor manoeuvre)
or Local/remote selector on 'local' position
or Local/remote selector on 'remote' position
FAULT RELAY :
The fault monitoring relay indicates a non-availability of the actuator or an abnormal operation.
The fault monitoring relay is normally energised, and is disenergised in case of fault.
The relay is disenergised upon the following events :
- Loss of main power supply, control voltage, fuse (*)
- Loss of 1 phase (in case of 3 phase supply)
- Tripping of motor thermal protection
- Local/remote selector in position local or off (**)
(*) Note : in case of power off there is no fieldbus communication, nevertheless if a backup supply
is connected the fieldbus interface is supplied and transmits the data main power supply is OFF.
(**) In case of local controls inhibition, selector in position local is not indicated as a fault, because
actuator is still available for the remote commands.
Options which can be choosen for the Fault relay with INTEGRAL+, POSIGAM+ or MODUGAM+.
- Local/remote selector on "local" or on "OFF" is not reported as a fault.
- Open torque switch tripped is a fault.
- Close torque switch tripped is a fault.
