316

317

When working with the Crown forklift, the algorithm for controlling the discharging contactor is changed. The state machine used to switch the discharging contactor is described below.

318

319

1) "Discharging off" state.

320

321

In this state, the discharging contactor is **open**.

322

323

If all the conditions are met:

324

325

* the charger is disconnected;

326

* the charging contactor is open;

327

* the “Critical error” is cleared;

328

* the "Undervoltage" error is cleared;

329

* the "Overcurrent" error is cleared;

330

* the "High temperature" error is cleared.

331

332

then the transition to the state "Load connection".

333

334

2) “Load connection” state.

335

336

In this state, the discharging contactor is still open and at the same time the battery voltage is switched to line A2 (see “Relay” status field).

337

338

If, after T = 10 seconds, the difference is |Voltage A2-Voltage A1| < “Delta voltage (tolerance)”, then the transition to the state "Load connected". If after the expiration of the time T the difference |Voltage A2-Voltage A1| > “Delta voltage (tolerance)”, then the transition to the "Crown error".

339

340

3) "Load connected" state.

341

342

In this state, the discharging contactor is **closed**.

343

344

If one of the conditions:

345

346

* the charger is connected;

347

* the “Critical error” is generated;

348

* the "Undervoltage" error is generated;

349

* the "Overcurrent" error is generated;

350

* the "High temperature" error is generated;

351

* Voltage A1 = 0V (load disconnection initiated by the forklift)

352

353

then the transition to the "Discharging Off" state is performed.

354

355

4) “Load disconnection” state.

356

357

In this state, the discharging contactor is still closed and at the same time the battery voltage is not output to the A2 line.

358

359

After T = 10 seconds, the transition to the "Load Off" state if performed.

360

361

5) "Crown error" state.

362

363

In this state, the discharging contactor is **open** and the "Crown error" is generated. If the "Inhibit discharging on the EWS signal" is not set, then after T = 10 seconds, the "Crown error" is cleared and the transition to the "Discharging Off" state is performed.

364
