MASTER CONTROLLER FOR WIND GENERATOR "IASOS III" MODEL H8000
MASTER CONTROLLER performs the following functions:
1. It is powered by the batteries in which the wind generator stores the electricity produced (INPUT 48 DCV).
2. Provides the final output current, from the wind turbine, for use (OUTPUT 220 ACV, 3 Kw).
3. Automatic closes and open the diffusers, according to ambient conditions (wind speed), batteries conditions (maximum permissible voltage), generator rotational speed and user will. In this way it effectively protects the wind turbine. All functions are done automatically with a pneumatic assembly, since the whole assembly also includes an air compressor.
4. Protects electronic and electrical circuits from overheating, as it has an automatic ventilation system (temperature-adjustable).
5. Allows the user, even from a long distance (3 Km), to close or open the diffusers, but also to cancel any automatic operation.
6. Offers digital precision indicators for each function.
is designed to:
INSTRUCTIONS ON USE AND CONNECTIONS DESCRIPTION.
The activity start when trigged one or more of the following five orders, provided that the EMERGENCY order, (can trigged only from remote control), is not already trigged.
1. BUTTON MANUAL CLOSE
3. RPM METER (generator)
4. VOLTAGE DETECTOR (batteries)
5. REMOTE CONTROL
The CLOSE action is connected in parallel with the five orders.
Whoever from the five orders be trigged, then starts the CLOSE action.
First the RELAY 1 be active and locks (self-triggering) with current from contact 8. The CLOSE valve be activated, the light on the BUTTON MANUAL CLOSE lights up and the DIFFUSERS IN MOTION indicator illuminates and sounds at the same time.
With the self-triggering procedure, even if an attempt is made to cancel the CLOSE order, the CLOSE action is not cancelled unless the EMERGENCY switch on the REMOTE CONTROL (D) is pressed.
The action OPEN cannot be activated during CLOSE action. This is because RELAY 1 also triggered RELAY 3, which interrupts any OPEN order.
When the CLOSE position sensor trigged the RELAY 2, that is, the diffusers are now closed, then TIMER 2 be activated, which will interrupt the minus of RELAY 1 at the set time (a few seconds) by essentially interrupting the self-triggering.
So the TIMER 2 will disarm RELAY 1, and with this way, the valve to OPEN will turn off, the light on the BUTTON MANUAL CLOSE switch will turn off, DIFFUSERS IN MOTION will go off and the audible warning will go off. At this stage RELAY 1 has no minus.
The TIMER 2 remains armed as long the CLOSE position sensor give the order.
At this stage:
If any order to close is active, every OPEN order is invalid because of RELAY 3.
If no one order to close is active, then the OPEN order can be executed. If the OPEN action starts, the diffusers will move, and therefore the CLOSE position sensor is not trigged any more. So RELAY 2 will disarm and will disarm the TIMER 2. This will disarm RELAY 1 in turn and it will be ready to accept and execute a CLOSE order.
If for some reason the CLOSE position sensor be anactive, RELAY 2 will disarm and thus disarm TIMER 2 and consequently RELAY 1 will take again minus current .
At this stage, if he receives a order from one of the five ordereds then the same process will start again to close the diffusers.
When one of the five CLOSE orders is active, RELAY 3 is armed to exclude the OPEN activity.
The activity start if one or more of the following three orders be trigged, provided that one of the five CLOSE orders is not trigged and the EMERGENCY REMOTE CONTROL command is not trigged.
1. BUTTON MANUAL OPEN
2. TIMER 1
3. REMOTE CONTROL
The OPEN action is connected in parallel to all three corresponding orders.
Anyone from the three orders give order, then starts the OPEN action, provided that one from the five CLOSE orders is not triggered, and is not triggered the EMERGENCY REMOTE CONTROL order.
When RELAY 3 is triggered, it means that one or more of the CLOSE orders is active and therefore the OPEN process cannot start. When RELAY 3 ceases to be triggered, then the OPEN procedure can be performed with any of the three orders.
If CLOSE command be active, during OPEN action, then OPEN action be cancelled.
During the OPEN process, RELAY 4 be in self-triggered, with current from contact 8. Then OPEN valve activated, the BUTTON MANUAL OPEN light illuminates and the DIFFUSERS IN MOTION indicator lights up and sounds at the same time.
Self-triggered means that even if one or all of the OPEN orders is cancelled, the process is not canceled. The process will be interrupted when the OPEN position sensor be activated, in turn activating RELAY 5, which in turn will activate TIMER 3, then interrupting the minus current in RELAY 5 and interrupting the self-triggering.
However, the minus current of RELAY 4 depends on TIMER 3.
When the OPEN position sensor stimulates RELAY 5, the diffusers are now open. Then TIMER 3 will be activated, which will interrupt the minus current of RELAY 4, at the set time (a few seconds), essentially interrupting the self-stringing.
With this way the TIMER 3 thus disables RELAY 4, the valve OPEN will be switched off, the light on the BUTTON MANUAL OPEN switch will turn off, the DIFFUSERS IN MOTION indicator will turn off and the audible warning will go off.
At this stage RELAY 4 has no minus current.
TIMER 3 stays armed for as long as the sensor for OPEN position is active.
Which means that RELAY 4 does not power the valve OPEN, nor the light
on the BUTTON MANUAL OPEN, because the diffusers are open.
One of the three OPEN ordered.
When the CLOSE position sensor be activate, it stimulates RELAY 2 and thus activates TIMER 1. At the set time, TIMER 1 will give its own command to open the diffusers.
If at this time another OPEN signal is commanded then the diffusers will be moved, the CLOSE position sensor will be disabled, RELAY 2 will be disarmed and TIMER 1 will no longer be triggered and the other orders will be executed.
When the diffusers start to open, at the order of TIMER 1, the CLOSE position sensor will interrupt the operation of RELAY 2 and hence TIMER 1. However, TIMER 1 will already have self-triggered the RELAY 4 and thus the OPEN process will continue.
In essence, TIMER 1 and TIMER 2 are activated simultaneously by RELAY 2.
RELAY 1 executes the CLOSE action.
The RELAY 2 is activated by the CLOSE sensor and activates TIMER 2 to disarm RELAY 1 a few seconds after the diffusers are closed. With this, the diffusers continue to push, for a little longer time, after the CLOSE sensor order to stop. The RELAY 2 also activates TIMER 1 and thus starts timing to attempt to open the diffusers.
The RELAY 3 allows or not the OPEN procedure to be executed, depending on whether a CLOSE order is active.
The RELAY 4 executes the OPEN procedure.
The RELAY 5 is triggered by the OPEN sensor and activates TIMER 3 to disarm RELAY 4 a few seconds after the diffusers have been opened.
The RELAY 6, when triggered by EMERGENCY command from BUTTON D on REMOTE CONTROL, disconnects the power supply to the valves (OPEN OR CLOSE) and any light or sound on the DIFFUSERS IN MOTION indicator.
