Monitor Actuator allows the user to monitor the status of IQ control inputs, internal functions and indication outputs with torque and position read outs in real time. The historical event log, recorded in the in-built IQ Datalogger can be "replayed" in the Monitor page for incident and operation analysis. Saved datalogger event logs can be replayed for analysis. Historical events are date and time stamped.
An "event" is a change in status of one or more monitored signals within the actuator, as viewed in the Monitor page. A logged event triggers a torque, position and time stamp in the Datalogger Event log to be recorded.
Warning. It is essential that the computer running IQ Insight indicates the correct, current time. Failure to do so will result in erroneous time stamping.
There a three "modes" in which monitoring can take place:
Real Time - monitoring the IQ for a selectable time during which the IQ "spools" data. This spooled data can be saved to file for analysis.
View File - monitoring a previously saved Datalog Event or "real time" spool data file.
Get Datalog - save the IQ Datalog Event log to file for future analysis.The page controls will change to suit the mode selected.

Monitor Page Controls - Real Time Mode
In the Mode control group, select the Real Time radio button.
Run Time
One Shot - Check the One Shot box to get a "snapshot" of current IQ status. The seconds, minutes and hour selector control will disappear. The one shot time is recorded. Click start to get current status. Click Virtual Display to view actuator display on screen.
Selectable Time - Uncheck the one shot control. Enter the required time for the spool, seconds, minutes or hours by highlighting and over typing.
Save to File - If a one shot or selected period spool is required for future playback and analysis, check the Save To File box. The Select File dialogue will appear. Click Select file and choose the required folder and file name.
If save to file is not required ensure the box is unchecked.
Note a spooled "real time" file is given the extension .spl.Virtual Display - Click Virtual Display control to see the IQ actuator display reproduced on screen.
Start - Click the Start control to begin IQ Spooling. The virtual IQ display will appear - drag it to a convenient screen position or click Hide to suppress it. Restore using the Virtual Display control. Changes in status of control inputs, internal functions including torque, position and indication outputs can viewed in real time on screen. If Save to File was checked status changes will also be saved to file. During the spool, if selectable time was chosen, the timer controls will count down. On reaching zero, spooling will stop.

Monitor Page Controls - View File Mode
In the Mode control group, select the View File radio button to view a previously saved Spool or Datalogger Event file. Refer to Get Datalog and Real Time, Save to File.
Select File - When the View File radio button is selected, the Select File dialogue appears. Click on the Select File control.
In the Select DataLog or Spool File to View dialogue use the Files of type dropdown to select Spooled Data Files (*.spl) or Datalog Files (*.dlg) to select the required file. Once selected the File location and name are displayed in the Select File dialogue. The event counter control, Event Player control and Jump Select control are displayed.Event Counter - the event counter displays the number of events, event 1 being the oldest, the high count being the most recent. The slider can be used to move through the events.
Note. The maximum number of events captured by the IQ Datalogger Event Log is 1024 events. When a new event occurs the oldest event is discarded. Therefore the latest 1024 events are always retained.
Note. Events trigger a torque, position and time stamp. Time cannot be entered in order to view contemporary events.Event Player - The event player forward (single >, forward x 10 >>) and back (single <, back x 10 <<) event controls can be used to step through the captured events. Refer also to Event Counter slider control.
Time - Mark/Clear. Event time can be viewed as elapsed time (since an event was "marked" or in real time.
Elapsed time - Display the required event. Click the Mark control. The time will be zeroed. Use the forward/back, Jump Select or slider controls to move through events. As events are displayed, the time indicated will be the elapsed time since the mark. Time is indicated in Hours: Minutes: Seconds.
Real Time - Click the Mark/Clear control to toggle between real time or elapsed time. Real Time is displayed as date - DD/MM/YY followed by time - hours: minutes: seconds (2 decimal places).
Note. The IQ datalogger does not use a real time clock. A "tick counter" is syncronised with the computers clock to show date and time. This means that no allowance for time zones or daylight saving is necessary, however it does rely on the computers time being current and correct.Replay - Click replay to start the player automatically stepping through logged events. Click Stop to return to player controls.
Jump Select - When a status change to one specific signal is of interest e.g. Torque Trip, all other signal status changes can be filtered out. Click Jump Select. In the Jump Select dialogue, click the required signal then click OK. Use the Back and Next controls to view status changes to the selected signal only. The player and slider controls act normally allowing events leading up to and after, the specific signal change to be analysed.

Page Controls - Get Datalog Mode
To view the IQ Datalog Event log it must first be saved to file. Select the Get Datalog radio button.
Select File - When the Get Datalog radio button is selected, the Select File dialogue appears. Click on the Select File control. The Select/Specify Datalog File to Save dialogue will appear. Enter a file name or, if required, highlight a previously saved file to be overwritten.
Note a Datalogger Event Log file is given the extension .dlgGet Datalog - Once a file has been specified, Click the Get Datalog control. The Datalogger Event File will be downloaded to the specified file. On completion a dialogue will open asking if the file is required for viewing. Click Yes to view, click No to close. A saved file may be opened at any time, refer to View File Mode.

Page Controls - Zero Datalog Data.
This control deletes all data stored in the Datalogger valve torque profile, statistical and Event logs. This control should be used with caution and only after saving data to PC file. Refer to Get Datalog and in Datalogger page, Save.
The Datalogger logs may be zeroed after valve/actuator refurbishment or a change in process conditions (pressure, flow, and temperature) when previous data may be no longer valid. It is important that the stroke constant is set/confirmed before zeroing the Datalog Data. Refer to Datalogger Stroke Constant.
NOTE. The IQ Datalogger Torque and Statistics Logs can only be viewed via the Datalogger Page. Zeroing the Datalogger will delete the Torque and Statistics Logs. It is recommended that Torque and Statistics Log is saved to file before using the Zero Datalog Data Control. Refer also to Datalogger Page.

Page Application Notes
The following notes give guidance on IQ signal status changes viewed in the Monitor page
Event. An event is a change in status of a monitored signal. For example, a simple local close command will result in 2 events being logged:
Event 1 - local close signal applied as the operator rotates the close control knob. Event 2 - local close signal removed as the operator lets go the close control knob. The torque, position and time coinciding with each event are stamped.Control Inputs. Local and remote inputs are represented on screen as pushbuttons. If control is via analogue signal via IQ Option Folomatic or network Option such as Pakscan, a command to move will be viewed as a pushbutton operation.
Indication outputs. The function set for indication outputs will be presented on screen. Contacts S5 to S8 are optional and may not be fitted. Check IQ wiring diagram for inclusion. Contacts S5 - S8 status will be presented regardless of whether they are fitted or not. To configure the function of indication contacts refer to Configuration.
Torque Indication. The IQ uses a unique, patented system for directly measuring torque output using motor shaft thrust. Thrust is converted to a voltage directly proportional to output torque by a piezo resistive transducer. Torque measurement is therefore reactive and will be seen in the monitor page changing with valve load. On stopping, the torque may be seen to decay as the motor shaft thrust decays with relaxation. The torque trip indicator (measured torque equals that set for the torque switch) will capture a trip event even if the event was of such a short duration that the monitor page torque value indicator could not display the actual value.
Alarms. The alarm panel indicates the status of control, valve or actuator alarms. Alarms are represented on the IQ actuator display as Icons, refer to Publication E170E.
Control - OK/Active. An active Emergency Shut Down signal or interlock will raise an alarm. Active ESD or Interlock signals inhibits IQ operation.
Valve - OK/Fault If the actuator trips on torque mid travel due to a tight or obstructed valve, the Valve fault alarm will be raised. The actuator latches the event and will not move in the same direction. If the actuator cannot move a valve, which may cause a stall condition, the valve fault alarm will be raised. Check the status of Torque Trip and Motor Stalled
Actuator - OK/Fault. If the actuator detects an internal fault the alarm will be raised. Check battery, 24V, mains, phase loss and thermostat status. Other actuator conditions responsible for raising this alarm are listed in Diagnostics. Refer to Diagnostics.
