EA.3078CTypical system loop diagram SKGeneral descriptionThis 3u high (128.4mm) by 6HP wide (30.14) slim line module is powered by 110/240V AC or 24Vdc obtained via its plug-in edge connector from the rack in which it is located.

4、The power supply circuit within the module is pre-set by soldered links to the specified input voltage and produces the stabilised dc supplies required within the module and for the external transducers associated with it.The module is capable of accepting PZA4 transducers and providing the transduc

5、er excitation output. Factory settings permit variations on current and voltage signal outputs. Adjustable latching or non-latching alarms may operate on the vibration term with either normally open or normally closed contact outputs. All these signal outputs are continuously available via the panel

6、 terminal blocks at the rear of the rack.Buttons on the front panel enables the module to be connected within the racking system to a monitor module located in the same rack or in another suitably- interconnected rack. A single display on the monitor, in conjunction with the front panel buttons on t

7、he signal conditioning module, can read three outputs in turn from any one module in the system at any one time. A SEL button and yellow LED indicator on the signal-conditioning module determines and indicates respectively which module is connected to the monitor.The signals available for routing to

8、 the monitor are a vibration signal together with alarm 1 and 2 set-points associated with that module.Any decimal point required by the monitor display is pre-selected within the signal-conditioning module so that different module types requiring other decimal point locations may share the same dis

9、play.The integrity of the signal conditioning module is self monitored by a green OK LED on the front panel which indicates PSU (power supplies healthy) and TXD (transducer healthy). Red LEDs indicate an alarm situation at vibration high and vibration very high alarm set levels. Latched alarms withi

10、n the module may be reset by means of a R/S button on the front panel.External commandsFacilities exist within the module for resetting latched alarms by external command, by a remote switch connected to the rack terminal blocks. This function by external command is: -a) CALibrate. This disconnects

11、the conditioned transducer signal within the module and connects instead a calibration signal. All compatible modules within the rack system will respond to this command and all their signal outputs will be proportional to the predetermined calibration signal level. If this latter level is above any

12、 alarm set points, then the alarm will operate.b) RESET. This will reset all latched alarms throughout the rack system (unlike the reset switch on an individual module that operates that module only).NOTES1. Specific versions of the MO.9602 (i.e. versions which have been internally configured to a p

13、recise specification) carry suffix letters and numbers on the basic type number which identify the version. An individual specification defines the various input/output parameters for each version. 2. The racking system intended to accept this range of modules is: - Type RA.8113-1C (Standard rack, 1

14、9” x 3u) Type RA.8113-2C (Half rack, 10” x 3u) (See separate handbook for details of rack) 3.

21、ntThe module is factory adjusted to provide correct display and signal outputs. The only adjustments accessible for the operator at the front panel are multi-turn potentiometers to set up the alarm levels.Assuming that the module is located within a type RA.8113 rack which also contains a monitor mo

22、dule type MO.9699 and that external connections have been made as per the relevant drawings, then the following procedure may be followed. With power applied: -1. Check that the green LED for PSU and TXD is illuminated.2. If any of the red LED alarm lamps are on, then depress and release the RESET (

23、R/S) switch on the front panel of the required module.3. Select the required module for display on the monitor module by depressing and releasing the SEL button at the top of front panel and note that the associated yellow LED illuminates and that the counterpart on other modules is off. The vibrati

24、on signal for that module will now be displayed at the monitor.4. If the A1 alarm level display is required at the monitor then depress and hold down the A1 button on the front panel. This level can then be adjusted, while holding down the A1 button, to the required level using the associated multit

25、urn potentiometer. On release of the button the display will return to the vibration signal.5. Alarm A2 can be adjusted in the same way as A1, using the A2 button and associated multiturn potentiometer. Note that for both alarms, the associated LED will light immediately when the signal exceeds the

26、set level but the relevant relay will not change state until after a small delay.6. The Calibrate facility may be checked by operation of an external command by contact closure via the AUX(illary) terminal blocks at the rear of the rack (see rack handbook for details). On the selected module the pre

27、-determined calibration signal level will be displayed at the monitor module. If either of the alarm set levels is adjusted below the calibration signal level, then the associated LED will light and the alarm will operate. When the calibrate function is operated the Calibrate Initiated yellow LED wi

28、ll be lit on the monitor module.7. The Monitor BNC at the bottom of the front panel of the module gives an output equal to the transducer input.8. The Reset (R/S) switch on the front panel of the signal conditioning module will not only reset any latched alarms (A1 or A2) within the module but will

29、also inhibit alarm relay operation while the switch is held depressed. If the incoming signal level is above the alarm set level the front panel LED will remain lit although the associated relay will reset (or be inhibited) whilst the reset button is depressed.9. The reset command can also be given

30、by contact closure via the AUX(illary) terminal blocks at the rear of the rack (see rack handbook for details) when all A1 and A2 alarms throughout the system will be reset (or inhibited). This function could be used to prevent alarms during the calibrate operation. The A3 alarm (PSU integrity) cann

31、ot be inhibited. When the external reset is operated the Reset Initiated yellow LED will be lit on the monitor module.Transducer InstallationTo achieve the best results it is important that the transducer measuring point is in the load zone of the bearing. The load zone is defined as the load carrying part of the bearing housing. It is normally determined by the weight of the supported machine part (i.e. the load is normally on the lowe
