The Control Mode Configuration affects
how the actuator will respond under
conditions of emergency shut down,
local control, remote control interlocks,
and 2-wire remote control. Also
included is an unseating torque switch
bypass function. Unless specified with
order, the control mode configuration
will be set as shown for default
configuration on page 63.
If it is necessary to change the
configuration follow the instructions in
this section.
There are 10 configurable control
functions:
A1 ESD action
A2 ESD contact type
A3 ESD thermostat bypass
A4 ESD override interlock
A5 ESD override local stop
A6 Maintained local control
A7 2-wire remote control
A8 External interlocks
A9 Conditional Control
At Torque switch bypass.
An active ESD signal applied to the
actuator will override any existing or
applied local or remote control signal.
ESD can be configured to override the
transformer thermostat, active
interlocks or local stop selection. Refer
to A3, A4 and A5.
The default action under an active ESD
signal is to stay put [SP].
Press the + or - key to select the
required ESD action:
[CL] Close on ESD
[SP] Stay put on ESD
[OP] Open on ESD
PRESS THE
KEY.
The displayed option will flash
indicating that it has been set.
ESD Set to Close
The default setting for ESD Contact
Type is [nO].
The actuator responds to a remote
control ESD signal derived from a
normally open contact making. For ESD,
where a remote control ESD signal is
derived from a normally closed contact
breaking, the signal being removed,
press the + or - key.
The display will change to [nC].
PRESS THE
KEY.
The displayed option will flash
indicating that it has been set.

Normally Open ESD Contact
Making (Signal Applied)
Note: If Folomatic analogue control is
required A2 must be set to [nO].
The default setting for Motor
Thermostat Bypass is [OF] during ESD.
The thermostats remain in circuit and
enabled during ESD.
The motor thermostats can be bypassed
during ESD as a factory set, hard-wired
option only. Contact Rotork for
information.
Danger: Actuator hazardous area
certification is invalidated while
the thermostats are bypassed.
A3 should be set to reflect the factory
set configuration of thermostat bypass.
During an ESD event:
[A3]=[OF] thermostats enabled
[A3]=[On] thermostats bypassed
