7.2.9 Position Trip for indication Contacts S1 – S8
(Parameters 82-85 and 90-93)
These parameters select the position for the contact to trip
at if the Intermediate position contact function has been
selected (if available).
7.2.10 ESD Parameters (Parameter 97 - 101)
The ESD signal is used to operate actuators to a pre-
determined state, under shutdown conditions. There are a
number of settings that can be made for this operation.
•
ESD direction (Parameter 97)
This parameter sets the direction of operation in the event
of an ESD signal being applied to the actuator.
•
Parameter ESD Contact (Parameter 98)
This parameter sets the polarity of the ESD contact, either
Normally Open or Normally Closed.
•
ESD Bypasses the actuator interlocks (Parameter 99)
This parameter selects whether an ESD will override the
interlock setting on the actuator.
•
ESD Bypasses the Thermostat trip (Parameter 100)
This parameter selects whether an ESD will continue to
operate in the event of a Thermostat trip.
•
ESD Bypasses Local Stop (Parameter 101)
This parameter selects whether an active ESD will still
operate the actuator even if it is in Local Stop.
7.2.11 Interlock enable (Parameter 102)
This parameter indicates if the interlocks are enabled or
disabled on the actuator.
7.2.12 Open Limit position (Parameter 103)
The DTM decodes this parameter to show the number of
turns that the actuator has been set to.
7.2.13 Interrupter Timer parameters (104 – 108)
The interrupter timer enables pulsed ‘start / stop’ operation as
a response to local or remote control commands. This can be
used to extend the valve stroke time. There are a number of
parameters that can be set up for this.
•
Interrupter Timer start limit (Parameter 104)
This parameter sets up the limit around which the
interrupter timer will operate, whether the open or the
closed limit.
•
Interrupter Timer off time (Parameter 105)
This parameter sets up the time that the interrupter timer
will stop the actuator for.
•
Interrupter Timer on time (Parameter 106)
This parameter sets up the time that the interrupter timer
will start and run the actuator.
•
Interrupter Timer activated when opening if below
xx% (Parameter 107)
This parameter sets the position that the interrupter timer
start to be active when the actuator is travelling in the
open direction.
•
Interrupter Timer activated when closing if above
xx% (Parameter 108)
This parameter sets the position that the interrupter timer
start to be active when the actuator is travelling in the
close direction.
7.2.14 Language used (Parameter 109)
This parameter indicates if the language used in the local
actuator display is the Standard English language or an
alternative one.
7.2.15 IDs and notes (Parameters 111 - 120)
The ‘ID’ parameters contain information about the serial
numbers of the Printed circuits boards inside the actuator.
The Manufacturing notes section contains details of the
manufacture of the actuator i.e. wiring diagram.
The final section ‘General notes’ is available to be written to
for any notes required.
