rotork IQT User Manual

7.1 The Setting Procedure
The Rotork IQT range of actuators is the
first that enables commissioning to be
carried out without removing covers.
Setting torque, limit and other functions
is achieved by using the Infra-Red
Setting Tool. The Setting Tool is certified
Intrinsically Safe to allow commissioning
in hazardous areas.
All the commissioning functions are
stored in non-volatile memory in the
actuator. The Setting Tool enables the
user to view all the functions in turn
via the actuator display window. As
each function is viewed its setting can
be checked and, if required, changed
within the bounds of that function.
Commissioning may be carried out with
main power switched on or off. Refer
to page 17 for Power Off Setting.
The setting procedure is divided into
two stages:
1. Basic Settings
Settings for end of travel limit
actions, torque values, limit
positions etc.
2. Configuration Settings
Settings covering the control,
indication and optional
equipment functions.
NOTE: For IQT Battery Failsafe
instructions, see Section 10 page 62.
WARNING:
All IQT actuator functions are
configured before dispatch to
Rotork standard default settings
unless alternatives have been
specified with the order. Should
difficulty be encountered during
commissioning the default
settings can be reinstated,
returning the actuator
configuration to its original
manufactured state. Site
commissioning can then begin
again
(refer to Section 9.18 page 59).
The default function should be used
with caution as settings selected after
manufacture may be essential for the
safe operation of the valve and/or plant.
