The end user or the contractor is responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment for the staff.
Maintenance1.1.7
Auma India multi-turn actuators require very little maintenance but they
need to be tested regularly for its correct functioning. After commissioning, check
actuator for damage to paint finish. Do a thorough touch-up to prevent corrosion. Correct
commissioning is a prerequisite for reliable service. Seals made of elastomers are
subject to aging and must therefore regularly be checked and, if necessary, exchanged.
It is also very important that the O-rings at the covers are placed correctly and cable
glands fastened firmly to prevent ingress of dust or water.
We recommend additionally:
If operated seldom, perform a test run about every 6 months. This ensures that the
actuator is always ready to operate. The version of actuators discussed in this manual
have an option for Partial Valve Stroke Test (PVST) to check if the actuator is healthy.
Approximately six months after commissioning and then every year check bolts
between part-turn actuator and valve for tightness. If required, tighten applying
appropriate torques.
The gear housing is filled with lubricant in the factory. This filling lasts for several years
of service.
Corrosions of paint damage parts must be prevented through touch up.
Any device modification requires the consent of the manufacturer.

2. INTRODUCTION
AUMA INDIA has developed a new range of electric actuators with intelligent
integral starter using microcontrollers for weather proof and explosion proof applications
that has the ability to store events and other upgraded features. As a microcontroller is
used, the actuators support both ON-OFF and Regulating Duty Control. The actuator can
also be run in Inching or Non-Inching mode. The important features of these electric
actuators are as follows:
2.1 LCD DISPLAY & LED INDICATION
Options can be selected by using the selector switches, push buttons based on the
instructions displayed on the LCD screen. Information on faults/statuses can be obtained
from the 4 LEDs next to the LCD. The 4 LEDs are configurable as per user requirement
before-hand. LCD screen facilitates easier understanding of status, operation and
parameter setting details. More information regarding this is described in section 3.
2.2 INBUILT FRONT PANEL OPTION SELECTION
Different features/options of the actuator can be configured using software. This is
done using the selector switches, push buttons based on the instructions displayed on the
LCD screen that is present on the front panel. More information regarding this is described
in section 3.
2.3 INTERFACES
This actuator is capable of supporting different types of interfaces like Remote –4
Wire, Remote -2 Wire Make/Break, 4-20 mA Regulating Duty & MODBUS-RTU.
2.4 EMERGENCY STOP - ESD
ESD feature is default configured to run in Close direction on enabling ESD. One needs to enable
ESD and set its behavior in Program Mode for it to function. An ESD via MODBUS option is also
available that needs to be enabled in Program Mode. ESD Operation can be configured for
OPEN/CLOSE/STAY. One can choose to set ESD on TOLR Ignore, TH Ignore, Space heater Fail Ignore,
OFF Ignore. This means that ESD operation would occur irrespective of these faults. One must enable
ESD on program mode and set its behavior (ESD Open/Close). An ESD NO/NC configuration is also

8
available that can be configured in Program mode. ESD feature now can be carried out using an
external 24VDc supply also.
2.5 EVENT STORAGE & DATALOGGING OPTION
This range of actuators comes with an option to store events such as faults, statuses, number of
starts (Open in Local/Remote etc. using a Bluetooth module. The events are stored in a flash
memory and can be read via Bluetooth. The data logged will have a real time stamp and can be
downloaded using a user-friendly application called Auma India Utility Software onto a PC/
Laptop with Bluetooth connection. About 43691 events can be stored at a time using this
module. AIUS is also used in assisting commissioning and diagnosing the actuators. Device Tag is
customer configurable. Remote Operation of actuator through Bluetooth is also available.
The available events are as follows:
Number of Starts (Open and close in specified duration)
Open and close Command with Selector Switch Position
Tripping Torque Profile (Non-Intrusive)
Faults.
oLoss of Phase
o
o24 V Fail
oThermal Switch Trip.
oTorque Switch Trip
oControl Supply Failure
oTOLR
Selector Switch Change.
End Position
ESD
More details of this feature is available in AIUS User Manual ( Doc. No.: 4-AIUS-MANUAL-39396).
2.6 PARTIAL VALVE STROKE TEST (PVST) OPTION
This feature is used in checking correct functioning of valves which are not operated for a
long period. When PVST is triggered the valve moves to particular percentage and come
back to the same end position and gives PVST result. The features are:
PVST can be triggered externally through a switch or via MODBUS.
PVST command can be given through MODBUS using dedicated registers.
PVST Position can be configured in the following two ways.
From Open End
From Close End
PVST Percentage can be set to any of the three options.
5%, 10%, 15%

9
PVST Failure : This failure occurs when the PVST command doesn’t take place after a specified time
(that is specific to actuators based on its RPM and No. of Turns). This failure is indicated by using
any one of the programmable relays present in your module.
2.7 INHIBIT OPTION
Inhibit is an interlock for open close operations. Inhibit Operation can be Enabled or Disabled in
Software (Program Mode). In this module, separate terminals for Inhibit Open and Inhibit Close are
available. Based on this, Open/Close Commands can be inhibited.
2.8 REMOTE SELECTOR SWITCH
This option allows the user to create a selector switch for the actuator in Remote mode. It is mainly
used to lock/unlock the Local operation of the actuator using push buttons through a Remote
command. This is serves as a software lock.
2.9 LOCAL CONTROL STATION (LCS) PRIORITY
When this feature is enabled, the user can control the actuator in remote 4 –wire mode of operation
even when in 4-20mA or MODBUS mode of Operation.
2.10 REMOTE LOCAL STOP
This option is also software configurable and can be enabled in Program Mode. The actuator
should stop running in Remote Mode when STOP key is pressed in the Actuator Front Panel. No
commands should be accepted by the actuator until it is reset.
2.11 TIMER MODE
Timer mode is used to control the valve movement. This mode allows us to open or close the valve
slowly towards the end position after reaching a certain distance with continuous operation.
Configurable Options
Open timer start Valve Position: The user has to set the valve position at which this Timer
mode should go on for Open Command.
Open ON time : This parameter decides the amount of time (in s) the actuator runs in Open
direction before shutting off for Open OFF time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).
Open OFF time: This parameter decides the amount of time (in s) the actuator shuts off
before running in open direction for Open ON time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).

10
Close timer start Valve Position : The user has to set the valve position at which this Timer
mode should go on for Close command.
Close ON time : This parameter decides the amount of time (in s) the actuator runs in Close
direction before shutting off for Close OFF time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).
Close OFF time : This parameter decides the amount of time (in s) the actuator shuts off
before running in open direction for Open ON time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).
