VMIVME5565 Gas turbine electric card

Connection of the binary outputs The following illustration shows the circuit configuration of the binary outputs. Features of the outputs: – The 16 outputs are arranged in two groups. Within one group, the outputs are not electrically isolated from each other. – The outputs can be loaded with a rated current of 250 mA. – Each group as a whole is electrically isolated from the rest of the device (see also Fig. 3–5). – The outputs use transistors and are short-circuit-proof. – The eight transistors of one group have a common power supply. – The outputs are automatically switched off in case of overload or short-circuit. – A overall error message indicates a short-circuit or an overload which has occurred on one or on several outputs. – An overload is displayed by the red LED K and via error flags in the PLC. – The user can set by means of a system constant whether the overloaded output is to be switched on again automatically by the PLC or whether it is to be switched on again by configuring within the PLC program, e.g. by means of the function blocks CS31QU or CS31CO. The default setting is the automatic reset of the outputs. – The red LED K goes out when the overloaded output is switched on again after eliminating the overload. – The acknowledgement of the error message, i.e. the resetting of the error flags, is done in correspondence with chapter A4.8 (Appendix), Acknowledgement of error messages in the central unit.

Battery and battery replacement

The lithium battery 07 LE 90 can be inserted into the battery compartment in order to – backup data of user program in RAM – backup data of additionally in RAM contained information, e.g. flag statuses – backup of time and date (real-time clock).

The battery lifetime is 1.5 years (typ. 3 years) at 25°C. The battery lifetime is the time during which the device remains operable in order to backup data while the supply voltage of the central unit is switched off. As long as there is a supply voltage available, there is no more load on the battery other than its own leakage current. The following handling notes have to be observed:
Use only lithium batteries approved by ABB.
Replace the battery by a new one at the end of its life.
Never short-circuit the battery! There is danger of overheating and explosion. Avoid accidental short-circuits, therefore do not store batteries in metallic containers or boxes and do not bring it into contact with metallic surfaces.
Never try to charge the battery! Danger of overheating and explosion!
Replace the battery only with the supply voltage switched on! Otherwise you risk data being lost.
Dispose of battery environmentally consciously!
If no battery is built-in or if the battery is exhausted, the red LED ’Battery’ lights up.

Operating modes of the serial interface COM1

 The operating mode of the interface has to be set according to the application in each case: – Programming and test or – Man–machine–communication MMC Active mode: The active mode is used for programming and testing the central unit, i.e. it gives the user access to all the programming and test functions of the central unit.

The special command assigns the value of ”1” to the image of the system constant KW 00,06 located in the operand memory. The PLC evaluates the value of this image and sets the kind of application of COM1 correspondingly.For the direction of reception, an End-of-text character is always necessary. This default End-of-text character (CR) must not appear neither in the message text nor in the user data of the assigned EMAS block. For the passive mode of COM1, the interface parameters can be changed using the SINIT function block. If the changed values are not plausible, the COM1 interface uses the default values. The interface is newly initialized each time the operating mode is switched over. The active-mode parameters are set in the active mode, whereas in the passive mode the parameters established by the SINIT block or the default values are set.
