WOODWARD 8402-319 8402-119 Servo speed governor

– 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.

Connection of the analog outputs

 The following illustration shows the circuit configuration of the analog outputs. Features of the analog outputs: – The analog outputs are not separated electrically. – Load capability of the outputs max. + 5 mA – Resolution of the D/A converter: 12 bits – Range of conversion: –10 V ... +10 V – Resolution 5 mV – If the numerical value in the PLC is changed by the amount of 16, the voltage at the outputs is changed by 5 mV.For further information see volume 2, chapter 5.1 General information on using the analog input and output modules. For 07 KT 92 ”Assignment b” is valid. Output 06,01 (analog output instead of the calibrated 10 V output) With the module 07 KT 92 R101, the terminal 52 was assigned with a fixed and calibrated output voltage of +10 V. Instead of this fixed voltage, the terminal 52 of the module 07 KT 92 R202/262 is assigned with a second analog output (channel No. 06,01). It has the same specifications as channel No. 06,00. If the output 06,01 must have a voltage of +10 V, the user program has to be added by the following instruction: !KW XX,YY = AW 06,01 with KW XX,YY = 32767 When replacing older modules with newer ones it has to be kept in mind that the output AW 06,01 only provides the +10 V voltage while the program is running

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 at 25 C (typ. 3 years). 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.
