CLOSE INTERLOCK
Bar ON = Close Interlock Active.
(Actuator disabled)
Unauthorised Close electrical operation
can be prevented by interlocking the
actuator (Close) control with an
external interlock contact.
If external interlocks are not required
the interlock function must be selected
OFF.
REMOTE NOT SELECTED
Bar ON = Remote control not selected.
Bar OFF = Remote control selected.
LOCAL CLOSE NOT PRESENT
Bar ON = Local Close signal not present.
Bar OFF = Local Close signal present.
LOCAL OPEN NOT PRESENT
Bar ON = Local Open signal not present.
Bar OFF = Local Open signal present.
THERMOSTAT TRIPPED
Bar ON = Thermostat tripped.
The actuator motor is protected by
thermostats.
Should the motor become overheated
the thermostats will trip and the
actuator will stop. On cooling the
thermostat will automatically reset,
enabling operation. See the actuator
nameplate for the motor rating.
LOCAL STOP NOT SELECTED
Bar ON = Local Stop not selected.
Bar OFF = Local stop selected.
LOCAL NOT SELECTED
Bar ON = Local control not selected.
Bar OFF = Local control selected.

When actuators are supplied for Vandal
Proof applications the local control
knobs are removed to prevent
unauthorised operation.
The local control functions are then
carried out by using the Infra-red
Setting Tool.
LOCAL CONTROLS NOT FITTED
Bar OFF = Local controls fitted
(standard).
Bar ON = Local controls not fitted
(vandal proof).

TORQUE SWITCH TRIPPED
Bar OFF = Torque switch tripped.
When the actuator generates a value of
torque equal to that set for Open
(when opening) or Close (when closing)
it will stop, protecting itself and the
valve from damage. This feature is
known as Over Torque Protection.
Once a torque trip has occurred further
operation IN THE SAME DIRECTION is
prevented.
This ‘‘latching’’ of the event protects the
actuator and valve from repeated
“hammering” against the obstruction
as a response to a maintained control
signal.
To ‘‘de-latch’’ the actuator it must be
reversed.
(For actuator torque adjustment, refer
to [tC ] and [tO] pages 25 and 26)
