Section 1: Partial Stroke Test (PST)
NOTICE
This Manual gives instruction regarding only the Partial Stroke Test function of ICON3000; detailed
and complete information for setting and control of the Electric Actuator ICON3000 are in the
ICON3000 Installation, Operation and Maintenance Manual, VCIOM-14012-EN which is part of the
mandatory instructions documentation.
! WARNING
It is assumed that installation, setting, commissioning, maintenance and repair works on ICON3000
are carried out by qualied personnel and checked by responsible specialists.
Section 1: Partial Stroke Test (PST)
The function Partial Stroke Test (PST) of ICON3000 is used to check the actuator and valve
functionality while they are in service in the pipeline. The test is performed only if the actuator
is fully open or closed.
PST function is available only if the setting of parameter “Restricted, Interlock mode” of ICON3000
is “Advanced.” In the above condition the hardwired inputs B4 and B5 of ICON3000 terminal board
work as input commands to initiate the PST cycle. Firmware version of ICON3000 base card should
be > = 9.00.
The following table shows the operation of the above inputs in function of parameter
“Interlock mode,” in the “VIEW and SETUP menu, Restricted,” (see Installation, Operation and
Maintenance Manual of ICON3000, VCIOM-14012-EN).
Table 1.
The PST cycle (Partial Stroke Test) consists in the following steps:
• To drive the electrical motor to move the valve to the congured position (PST travel)
• To measure the time to reach the congured position (T-PST)
• To stop the motor when congured position is reached and measure the over-travel
% (OV-TR)
• To stay in position for a congured time
• To drive of the motor to move the valve in opposite direction to the initial position
• To measure the time to return to the initial position (T-RET)

Parameters of PST 3
Section 2: Parameters of PST
Section 2: Parameters of Partial Stroke Test
The following parameters are available in the local operator interface of ICON3000, VIEW and SETUP
menu, ACTUATOR SETUP, PST SETUP routine, to set PST function behavior:
1. PST mode: OFF, AUTO, MANUAL
— OFF: PST function disabled
— AUTO: PST cycle carried out automatically and cyclically with time interval set by
the parameter PERIOD and at time set by the parameter HOUR of DAY
— MANUAL: PST cycle carried out on receiving of a remote hardwired PST signal
or by local command available in the “VIEW and SETUP menu, Maintenance
functions” of ICON3000
— MAN-AUTO: both automatic and manual mode initiate the PST function
2. PERIOD: time interval between PST’s in days, congurable from 1 to 1000, in PST mode “AUTO”
3. HOUR of DAY: hour of PST, in hour, congurable from 0 - 23, in PST mode “AUTO”
4. PST TRAVEL: position travel during PST cycle, in % of position, congurable from 5 - 40.
If actuator is fully open it moves from 100% to “100-PST TRAVEL %”, if actuator is fully
closed it moves from 0% to “PST TRAVEL %”
5. MAX T-PST: max time allowed carrying out the PST TRAVEL, measured in % of relevant
BASELINE time, congurable from 1 - 1000%
6. MAX PST T-RET: max time allowed to return to initial position, measured in % of relevant
BASELINE time, congurable from 1 - 1000%
7. PAUSE: time of stay in position of actuator, in seconds, congurable from 2 - 255 seconds
8. MAX PST OV-TR: max position over-travel allowed to actuator during PST cycle, in
percentage of position , congurable from 1 - 100

Command to PST Cycle4
Section 3: Command to PST Cycle
Section 3: Command to Initiate the PST Cycle
PST cycle initiates only if:
• actuator is fully open or closed
• local selector of actuator is in REMOTE or LOCAL
• local STOP, remote STOP (only in the option 4 wires mode) and ESD are not active
The parameter “PST mode” sets the following modes to initiate PST cycle:
• “AUTO”: the PST cycle initiates at the hour set by the parameter HOUR of DAY and when
the time past from the last PST is equal to parameter PERIOD. The test is performed if the
actuator local selector is in LOCAL or REMOTE.
• “MANUAL”: if the ICON3000 local selector is in REMOTE, the PST is performed on receiving
of the hardwired command on the ICON3000 terminal board. Terminal B4 is the input to
perform PST in open direction and terminal B5 is the input to perform PST in close direction.
Refer to relevant electrical diagram for wiring details. If the ICON3000 local selector is in
LOCAL, the PST can be initiated by the command available in the menu “VIEW and SETUP
menu, SETUP, MAINTENANCE routines, PST cmd”.
• “MAN-AUTO”: both conditions described in “AUTO” and “MANUAL” initiate PST action.

Reset of PST Cycle 5
Section 4: Reset of PST Cycle
Section 4: Reset of PST Cycle
PST cycle aborts in the following conditions:
• To move the ICON3000 Local selector to OFF, LOCAL or REMOTE while PST cycle
is in progress
• Alarm of electrical actuator ICON3000
• To press the Local STOP pushbutton
• To press the remote STOP command (only if option “4-wires” is used, see Installation,
Operation and Maintenance Manual of ICON3000, VCIOM-14012-EN, Remote Control)
• ESD command

PST Curves and Baseline6
Section 5: PST Curves and Baseline
Section 5: PST Curves and PST Baseline
During PST cycle the actuator position % and the relevant time are collected in the RAM memory
of ICON3000. At the end of PST cycle the PST prole (position versus time) is memorized in the
permanent memory. The memory contains up to 16 PST proles. When a new set of data is available
the oldest prole is deleted and the new one is stored.
By the command “SET PST REFERENCE”, available in the local operator interface, option “VIEW and
SETUP menu, SETUP, MAINTENANCE” routines, 1 out off 16 “PST curves” can be copied and frozen in
the “PST BASELINE” memory.
The BASELINE curve can also be done by the PST command, available in the “VIEW and SETUP menu,
SETUP, MAINTENANCE, PST cmd” routines. By selecting the option “BASELINE” the PST command
causes the PST cycle execution and the collected data are saved in the PST BASELINE memory.
The “PST BASELINE” can be updated only by a new “SET PST BASELINE” command.By the comparison
between PST BASELINE and PST curves, the ICON3000 can produce status and warning useful in
maintenance operation.
By PC or PDA and A-Manager software tool, the curves can be read from ICON3000 and then
visualized and compared in a graph.

Section 6: PST Report and Warning
Section 6: PST Report and Warning
At the end of PST cycle the new data collected are compared with the BASELINE and the setpoints
“MAX T-PST, MAX PST T-RET, MAX PST OV-TR to produce the following status and warnings:
Table 2.
Warning can be viewed by the local operator interface of ICON3000 or by a PC/PDA connected
via Bluetooth interface. Warnings are also recorded in the warning log registers (see Installation,
Operation and Maintenance Manual of ICON3000, VCIOM-14012-EN, VIEW and SETUP menu,
maintenance routines).
