Page 27: Operation
CHAPTER 4 OPERATION LED Control Operation and Status Function The ON/SLEEP state of the Simple Logger II can be determined by press- ing the PRESS button for shorter than 0.5 second. If the instrument is ON, the status of the instrument will be shown by the LEDs. If the instrument is in SLEEP mode, all the status LEDs will light until the PRESS button is released. Once released, the status indication resumes. If the instrument is in its sleep state, it can be woken up by pressing the PRESS button until all LEDs light. At this point, the button can be released to show the status of the instrument. Control of the instrument is performed by pressing and holding the PRESS button until the control LED corresponding to the desired operation lights. Releasing the button when the desired control LED is illuminated results in the corresponding operation being performed. When holding the PRESS button, each LED will light in sequence. Con- tinuing to hold the PRESS button will result in all LEDs being off after the last LED lights. If you continue to hold the button down, the sequence will repeat with the first LED. Releasing the button after the last LED turns off and before the first LED turns on will result in no action being taken by the instrument. This provides a mechanism to cancel (or ignore) the button press. The instrument will go into a sleep state to conserve power before a scheduled recording starts and will wake up shortly before a recording start time. - Page 28 The Control and Status Operation of each LED is as follows: GREEN LED CONTROL Starts a Recording Single-blink Logger is in Standby Mode (and not recording) STATUS Double-blink Logger is in Record Mode ORANGE LED CONTROL Stops a Recording Logger is not in an Overload condition STATUS Single-blink One or more inputs are in an Overload condition YELLOW LED...
-
Page 29: Battery Use
Overload occurs when any input is 10% above its input range. When the battery voltage goes below 1.7 volt the instrument will shut down (termi- nating and saving the recording, if it is recording). • SLEEP mode: The instrument enters the low power state if the button is not pressed for one minute. It will remain in this state until either the button is pressed or the internal clock reaches the start time for a scheduled recording. •... -
Page 30: Recording Data
Recording Data The Simple Logger II must first be configured before a recording can be ® performed (see the DataView Simple Logger II Control Panel Help). ® Once a configuration is written to the instrument, the logger will no longer need to be connected to DataView to start the scheduled recording. ® When data is stored in the memory, the user may download the informa- tion onto a hard-disk. A scheduled recording will still start even if the logger is in sleep mode. 4.3.1 Starting a Recording Session A new recording cannot be started if the memory is full. -
Page 31: Downloading Recorded Data
Downloading Recorded Data Recorded measurements stored in the instrument are transferred to a computer via the DataView Simple Logger II Control Panel, as described in the Help system that comes with the program. Clearing Alarm Indication Clearing alarms can be performed in the STANDBY or RECORD mode. 1. Press and hold the PRESS button. When the ALARM (YELLOW) LED lights up, release the button. The YELLOW LED will blink at a fast rate for a period of five seconds. 2. Press the PRESS button for another 0.5 second to complete the oper- ation. This does not clear any stored alarms, only indications. Stored alarms can only be cleared when memory is erased (see § 4.6). Erasing Data from Memory Erasing data from the instrument’s memory can only be performed while in the STANDBY mode. -
Page 32: Data Storage
If the button is not pressed within five seconds of arming, the erase oper- ation will automatically disarm and memory will be maintained. For this reason, if you do not intend to erase memory, simply wait until the RED LED stops blinking at the fast rate. Erasing the Memory using the Simple Logger II Control Panel: 1. Connect the instrument to the computer, then open the Simple Logger II Control Panel. -
Page 33: Logger Operation
Logger Operation When the instrument is in STANDBY mode, the following occurs (provided there is sufficient battery voltage and no data is stored in the instrument’s memory): • The GREEN LED single-blinks every 5 seconds. (STANDBY mode is active and the logger is not recording). • The RED LED is OFF, indicating there is no data in memory. • The PRESS button is used to Start/Stop a Recording Session. • If the PRESS button is not pressed for a period of one minute, the instrument will enter SLEEP mode and wait for either another button press or the recording start time to arrive (if a recording is scheduled). While in SLEEP mode, the LEDs will not blink. • A button press of 0.5 second will return the unit back to the normal STANDBY mode. 4.8.1 Recording with Memory Cleared When a recording starts, the logger will continue to record until one of the following occurs:... -
Page 34: Memory Filled During Recording Session
The logger memory cannot be erased while in the Record mode. The recording must be stopped first. 4.8.3 Memory Filled During Recording Session (Start/Stop Mode) If the logger is recording using the Start/Stop mode and memory is filled before the Recording Session has finished, the session will end. The following happens after the PRESS button is pushed for 0.5 second: • The GREEN LED single-blinks (standby mode). • The RED LED double-blinks (full memory). At this time: • The memory can be downloaded and erased. • A new recording can be started or scheduled once memory is erased. If in either the XRM or FIFO mode, the recording will continue even after memory becomes full. -
Page 35: Recording Session Has Ended
4.8.5 Recording Session has Ended The logger will be in STANDBY mode if one of the following occurs: • The session terminates due to recording end time being reached. • The recording in START/STOP mode fills the memory. • The user terminates the session by pressing the PRESS button until the STOP (ORANGE) LED lights up and releasing the button before the next LED lights, or issues a Stop Recording command from the Simple Logger II Control Panel. The logger is now ready for a new session or download. Pressing the PRESS button until the START (GREEN) LED lights up and releasing the button before the next LED lights, will start a new session depending on the available memory. Event Logger Operation (Model L404) The Model L404 monitors up to four channels for the occurrence of events and stores information about each event. The rate at which each input is tested for the event status is defined by the sample period. Events that are shorter in duration than the period between sampling can potentially be missed. For this reason the sample period should be chosen to be at least twice the fastest event rate, e.g. an event being monitored is expected to occur no faster than once per minute. The sample period... -
Page 36: Sample Event Capture
The logger will store on event, which means that if there is no change at the input of the instrument, it will not store any data until the next event cycle occurs. This happens when the instrument sees the changes at an input, as previously described. If the expected event rate is 1s, then it would be necessary to set the sample rate faster than once per second in order to capture the events. As mentioned previously, the timing accuracy of the captured event is dependent on the sample rate. The faster the sample rate, the higher the timing accuracy. Minimum duration of an event will need to be the duration of the sample rate such that if the sample rate is 125ms, then the pulse will need to be at least 125ms to be certain that the logger will capture the event. 4.9.1 Sample Event Capture Figure 4-1 The above example assumes that the “Invert display polarity (event displayed as a high)” is selected from the scales tab of the configuration... -
Page 37: Application Examples
4.9.2 Application Example In a processing plant it has been determined that timing on several positions is out of specification. The service staff needs to know the sequence of valve opening and closing, and the duration of each, to correct the problem. The L404 can be connected to four outputs in the process and keep track of the time and duration of each opening and closing, thus providing the technician with the data they need to solve the sequence issue. In the example below we can see that the valve 1 opened and closed several times during a one minute period, but valves 2, 3 and 4 did not respond. Figure 4-2 4.10 Reset Switch Operation CAUTION: Risk of electric shock. Disconnect the unit from any input source before opening the rear cover. -
