13、al-RAM. KINThis component is dedicated to the transformation of DI Quantities s. It passes to CPU DI quantities, which come from console, relay circuit or other controlling device. ADFThis component is dedicated to the transformation of analogue Quantities s. It adjusts the signals of voltage and cu

14、rrent coming from PT/CT Component and passes to AD for amplitude measurement or to HIS for frequency phase measurement. PT/CTThis component is dedicated to the isolation of voltage and current. It changes output of PT and CT into small signals and passes them to ADF Component. PTs and CTs used in HB

15、PST are all high-accuracy current-output model. KOUT1、KOUT2KOUT1 and KOUT2 Component are all responsible for output of DO Quantities s. The DO Quantities s are output in the form of Empty Connector. They can connect with Lighting Board, DCS or other device. They are self-hold. COKThis component is d

16、edicated to transformation of output signals. This component combines the signals coming from CPU and sends them to Relay Component after photoelectric isolation and amplifying of isolation relays. COK Component holds orders about 5 ms. OUT1、OUT2They are components of output relays. They translate t

17、he orders of COK Component into Closing or Opening signals of relays and output in the form of Empty Connectors. The output current can be up to 5A and can be self-hold.

18、re, it has monitoring circuit of the device switch -power supply. The output of switching-mode-power-supply is +5V，15V and +24V. Any circuit break will lead to a warning. PWRIt is a switching-mode-power-supply component. It changes DC220V or DC110V voltage into +5V，15V and +24V. The embedded Voltage

19、 Delay Circuit can prevent the HBPST from sending error order or signals in the process of power-on and power-off. The switching-mode-power-supply can be for ac or dc use.2.3 Backboard Pinouts2.3.1 Layout of Backboard PinoutsThe layout of backboard pinouts are shown in Diagram 3.2.3.2 Introduction o

If a lighting board is lighting that show working status is abnormal, operation personnel must do with ac

47、cording to working status. After that press RESET key, the lighting board is reset. Equipments Power Lost. Checking equipment DC power supply voltage, including the fuse of equipment cabinet DC power supply input line 、the status of equipment cabinet gas-switch is on 、the status of equipment power s

48、upply part switch is on , if these are normal, please check the +5、+15、-15 and +24V lights in small board of equipment power supply part, do so can make sure which kind voltage is abnormal. If the fault is because of the equipment self (including equipment power supply part), please contact with us

49、immediately. Equipment Locked. This is a total signal that shows the equipment is in locked status because of some causes, the reasons can be checked from lighting Boards status or the “Abnormal Report” menu. The reasons result in equipment locked may be:n Switch Completely. This shows switch has be

50、en completed successfully.n PT Line Break. This shows one or two phases bus voltage is low in the three phase bus of plant self using, the reason may be PT line break. Please check carefully.n Protection Locked. This shows equipment has received exterior “Protection Locked” instruction, means exteri

51、or input “Protection Locked” contact once were closed, please check Protect OK. n Backup Power Supply Lost. If backup power supply lost locked function is used, when backup power supplies the bus of plant self using, such as before generator starting or after generator stopped, in this case, generat

52、or has not output voltage , so work input line PT has not voltage do not satisfy with switch condition, equipment will be locked and send locked signal. In the same way, when generator supply the bus voltage, if the voltage of backup power supply is lower than setting value, the lighting Board will

53、light. But if drop out the backup power lost lock function from “Mode Setting” menu, equipment will not send the signal of backup power lost and the signal equipment locked. n Equipment Abnormal. When the lighting Board is lighting, show equipment self checks some primary parts are wrong, please con

54、tact with us immediately.n Switch Location Abnormal. In many cases, the lighting Board is lighting. Please see 2.3.2, check reason. 4.2 Panel Checking Running Status Indicating Lights. “Working Power” and “Standby Power” indicating lights should have only one is lighting when equipment is normal. “Running” indicating
