4, remote control operation (open/stop)
Remote-control operation mode is opposite according to practical application situation to be changed, such as: passive contact non-self-lock-ing controls, is passive
From lock control, the control of active non-self-lock-ing, active contact from lock control etc..It is described herein are as follows: active voltage DC24V trigger-type
Control model；
A, which is far controlled, to be opened: the DC24V relay when No. 1 terminal and No. 2 terminal of the external DC24V trigger voltage Jing Guo terminal plate X1
Device KJ1 coil obtains electric → remote control lock SA2(lock-controlled switch, plays safeguard protection, which is two kinds of orientation states: left-handed 45
To close → forbidding, contact disconnects degree；45 degree of dextrorotation to open → allow, contact closure) be the normally closed point closure of permission state → KJ2 →
KJ1 opened point closure → KA303 and KA303` coil is attracted → KA303` opened point closure → self-locking KA303 and KA303` simultaneously
Coil；KA303 opened point closure → PLC1[I0.5=1] while KA303 normally opened contact closure → PLC2[I0.5=1]；
Input signal, software can voluntarily distinguish and take turns starting 2 groups of pump motors to 2 groups of PLC input port I0.5 of b simultaneously,
(it is proper in order to use every water pump all for why needing 2 groups to take turns starting).Once it is determined that any one after starting group
Group PLC can voluntarily output signal, after system detection arrives the start command starting failure executed, can be automatically within 20 seconds
Another set starting is converted to, and prompt trouble light and backstage record fault condition, I group of Starting mode and this paper on panel
2 nearly control operation b are the same, and II group of Starting mode starts as I group/II group conversion b with herein 3；
C, which is far controlled, to stop: the DC24V relay when No. 3 terminals and No. 4 terminal of the external DC24V trigger voltage Jing Guo terminal plate X1
Device KJ2 coil obtains electric → remote control through permission state and locks the normally closed point disconnection → KA303 and KA303` coil of SA2 → KJ2 while falling
Electricity, 2 groups of PLC input ports [I0.5=0], software execute halt command, I group of stopping process and herein 2 closely control operation c automatically
Equally, II group of stopping process starts as I group/II group conversion b with herein 3.So just complete entire remote control process
A loop control.
5, test is opened certainly
Since Fire Control Cabinet can not often be run, so every month will do one-shot test for pump motor,
To prevent equipment does not have to for a long time and leads to the failures such as dampness, also for checking potential faults in advance.In this equipment man-computer interface
Specific starting time, the dwell time of each of which month, accurate unit are as follows: second can be set on touch screen；
After opening test wherein time satisfaction certainly, system can shift to an earlier date 10 minutes and prompt sound-light alarm per minute a, then hold
Row start command → PLC1[Q0.3=1] → open lockhole switch SA1 certainly to allow position (equally mainly to play guarantor with the above SA2
Shield effect) → KA153 coil obtains electric, two groups of normally opened contacts closures trigger simultaneously respectively inside KA153, execution program later and
