Commissioning
7.1 The Setting Procedure
The Rotork Fluid Systems EH actuators
are designed so that commissioning
may be carried out without removing
any electrical covers.
Setting the internal hydraulic pressure,
limit and other functions is achieved
by using the Infrared 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.
The power supply must be connected
and energised for commissioning
purposes. The setting procedure is
divided into two stages:
1. Basic Settings
Setting end of travel limit actions,
pressure values and limit
positions.
2. Configuration Settings
Settings covering the control,
indication and optional
equipment functions.
All EH actuator functions are
configured before despatch
to Rotork Fluid Systems
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.
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.
