The optional graphic display is intended for on-site visualization of measurement data, lists and alarms of the SINEAX CAM. The operation of the display is performed by means of the keys. Using the keys the user may acknowledge alarms or extreme values as well. Which data can be displayed depends on the version of the device, especially which I/O modules are present and which options are activated.
1. Display structure and operation Generally When first switching on the device the main When changing the display window menu is displayed. On every further start-up the there may be a waiting time, which is last displayed image before the power-down is symbolized by displaying a sand shown.
2. Settings select a parameter group Invoke the line settings in the main menu. This line will be visible only if the selection is shifted downwards. In the menu settings go to the line with the desired parameter group using the keys .
2.3 Settings of the clock The SINEAX CAM has an internal clock, which To handle this problem the SINEAX CAM uses is used as a time reference for alarms, events, internally UTC time only (see below). The user progression of measurements and so on. Due...
3. Security system The device supports a security system which For the display the following functions may be allows to selectively assign rights to different protected using the security system: users. Thereby rights for the changing of - Reset of meters and extreme values measurement or configuration data or the - Settings of display, interface and clock simulation of I/O data may be granted.
4. Display measurements The Measurements menu has more entries as directly can be displayed. Via main menu the menu measurements may Meters: All acquired meter contents of the be invoked. There the following data are measured system and the I/O's. available: I/O, relays: Measurements resp.
4.2 Measurement display of system quantities Present: Contains the instantaneous values of the system Minimum, maximum: Shows all acquired minimum and maximum values with timestamp Reset minimum, maximum: Allows to selectively reset the acquired extreme values Present This predefined assembling of measurements consists of multiple pages.
4.3 Measurement display of harmonics Present: Contains the present harmonic contents as well as THD and TDD Maximum: Contains the acquired maximum values with timestamp Reset maximum: Allows to selectively reset the maximum values Present Each page shows a graphical overview of the present harmonic contents (U or I) and the value for one individual harmonic.
4.4 Display meter contents Meter contents are acquired for both the measured system as well as for analog inputs. For digital inputs it takes place only if the inputs are configured as meter inputs. Meters For each meter the contents for high tariff (HT) and for low tariff (LT) are displayed.
4.6 Measurement display of mean values Mean values may be acquired with two measurement displays are variable. Up to 12 different interval times t1 and t2. The different pages may be displayed. The selection corresponding measured quantities are freely is performed using the keys configurable.
4.7 Measurements for wiring control The wiring check shows measurements for voltage and current of all phases and the direction of energy flow of the currents. If all voltages have almost similar values and the energy flow direction of the currents is equal it may be assumed that the wiring has been performed correctly.
5. Alarms Via the logic module of the SINEAX CAM The acknowledgement resets a possibly complex contexts may be monitored. Out of defined further action, e.g. the switching of a them alarms can be generated, which are relay output. The alarm handling is possible...
6. Lists The option Lists allows to perform a All recordings can be displayed on request, with chronological recording of events, alarms or time stamp and dedicated text. If the security system messages. At a later time it's possible system has been activated for specific displays to understand and analyse each state also the involved user is available.
