锂电电动车控制器线束定义
锂电控制器使用方法
1.将各功能线正确接入车;
2.打开电源,电机慢速转;
3.调整电机方向则拨插学习线；或再拧一次转把（学习线未拔时）
4.方向确认后必须拨掉学习线
5.拧转加速手把,电机正常转动,OK!
锂电控制器的双门锁线用法
说明:子弹壳长带电,实际就是电池的正极电压;
子弹头,门锁电压输入端,这根线只有接入电池电压控制器才可以工作.
***有的车子习惯直接用电池正极粗线接入钥匙开关,这样就
省掉了电门锁线,但是此时必须对插双门锁线.否则控制器不工作!
注：对于不用门锁线的控制器（电池总正极直接接入电锁开关时，原因是当电门长时间关闭后控制器失去记忆电压后，极少数控制器可能在车电门打开时反转，此时只需重新学习一下即可。

）
使用中控制器常见的问题
1.刹车不断电：低电平刹车线接入电池的负极是否可刹车，黄
线常态为4.7-5V。

2.不能变速：检查变速线是否接入牢固，电机霍尔损坏也影响
变速。

当负载电流超过8A时，超速不明显。

检验超速功能是否有效的办法是：将车子架空加速测试。

3.不能助力：拨掉助力总成霍尔插头.测控制器助力红黑线常态
应为4.7-5V,绿线电压应为5V左右.否则不正常.
4.不能定速：检查控制器白色线是否与地线对接,对接后电压为
0V,定速时为0V.不定速为4.7-5V!。

It is shown at start-up of the controller and the VCI07 will revert to this menu after one minute when the keyboard activity stops while displaying a different menu. The following messages are displayed :• Machine status (e.g. standby, blowing down, onload, offload, etc.) • Time and day• Errors - active faults are blinking (e.g. air.

This signal is based on a PI control algorithm and can be used to drive an actuator (e.g. a proportional valve or a frequency inverter). The pressure regulation algorithm will control the actuator in order to maintain the load pressure at all time. If the actuator can not sufficiently cut back, the compressor will rise until it reaches the unload pressure. The compressor will then unload and the PI pressure control algorithm is disabled. As the pressure goes down and reaches the load level again, the compressor loads again and the PI control will take over. (see Table 6, Chap. 3.3.4)09/04Worthington-CreyssensacPage 1062 205 930 11ATTENTION :Do not adjust correctors P and I. They undergo in-factory configuration for compatibility with more than 95% of installations. During the setup, the installer checks the settings.

Every zero passage of the 24VAC main is detected. When 2 consecutive cycles or a power failure of 40ms is detected, the controller will automatically stop the machine. At the same time, all relays are released and 3 horizontal dashes are displayed on the LED display. By stopping the machine during a micro power interruption, sparks on the relay contacts are avoided which will extend the relay lifetime.4 - ContrastThe only possible adjustment is the visual angle of the alphanumeric display. In the factory this angle is already adjusted to its best position. When another angle is wanted it can be changed by removing the black cap at the bottom of the unit. Just behind the aperture a 270 degrees potentiometer is located. Use a screwdriver with a 25mm blade or less to make the adjustment. Do not forget to replace the black cap.5 - MaintenanceThe VCI07 does not need maintenance. When the front panel is dirty, it can be cleaned with a soft cloth drenched in soap water or methanol.6 - Start up and optimising final machine adjustmentsThe machine undergoes in-factory configuration in order to limit the need for adjustments during installation. Therefore, only the pressure thresholds need to be set :- “OnLoad P” = desired regulation pressure (in vari-speed)In order to conserve energy to the maximum, it is advised to lower the regulation pressure to thelowest possible level ( so as to optimize power)- “Offload P” = Delayed stop pressure of the machineFor energy consumption that is less than the minimum capacity , it is advised to set it at + 0,5 barabove the “P load”.In certain rare cases, it may prove useful to adjust the regulation settings (see chapter 7, main operational occurrences).7 -Main occurrencesOccurrences Solutions1. THE MACHINE STOPS AND STARTS AGAIN BUTONLY FOR A SHORT TIME Increase unloading time (for +5 to +20 s) so that the motor doesn’t stop so often (the compressor runs for longer before stopping). If this delay is insufficient, increase the “unloading time” and the minimum unloading time by the same amount (for example : +30s)2. THE MACHINE STOPS, DISPLAYING THE MESSAGE”MOTOR ERROR” Check that there is no mechanical blockage of the motor. See variator instructions : the fault comes from the variator. Identify the fault.Ne pas réinitialiser la machine sans chercher la source du problème.3. THE OIL TEMPERATURE IS TOO HIGH (THEMACHINE STOPS OR AN ALERT IS GIVEN) Lower the pressure to the min. level that the client will need. Decrease the “dry fact” setting by 2 to 10%In the event of failure, proceed more progressively : by consecutive steps of 1 to 2%, testing each time the rise in machine temperature.In this way, machine cooling is steady and total absorbed power is reduced (as is the case with the capacity)4. THERE ARE LARGE FLUCTUATIONS OF PRESSURE(MORE THAN 0,2 BARS) FOR FLOWS IN BETWEEN THE MAXIMUM AND MINIMUM CAPACITYI. Read the variator frequency (see variator instructions) Check that it is higher than the minimum frequency (the capacity is thus higher than the minimum capacity). If this is the case, reduce the integral factor (I factor) so as to reduce fluctuations.Attention : reducing it too much will slow the rise in pressure.5. THE PRESSURE DOES NOT RISE QUICKLYIncrease the P factor.6. THE MACHINE EQUIPPED WITH A DRIER DOESNOT START Wait or reduce the ‘dém séch‘ drier starting time to 0 min for machine starting.7. THE MACHINE STOPS AND ‘‘ERR T. MOTEUR’’ ISDISPLAYED The variable speed motor is overheating (RLR 220V). Check that the machine is not operating at an excessive ambient temperature (> 40 °C)8. THE MACHINE STOPS AND (DRYER FAULT) ISDISPLAYED The drier low temperature threshold has been reached Contact your After Sales Service to check that the drier is not frozen, (if the drier is not frozen, it is possible to maintain the drier low temperature threshold in the drier menu)8 - Dryer ManagementThis controller is compatible with the integral dryer and specific variable speed motor options. Dryer Management- The VCI07 may be configured in three manners to control the dryer:•- - - “no message”•Ale “Alert” (default setting)•ERR “Stop on FAULT”- - -Bottom Message/Top Message/Ale Dryer t. too low Dryer t. too highERR ERR : Dryer t. low ERR : Dryer t. highA start time before compressor starting can be indicated (see Chap. 3.2 “Base” settings).Dryer freezing- The VCI07 indicates a dryer alert when the dryer temperature is less than the bottom threshold value:It displays “Dryer t. too low” and the machine does not stop.The unit may be stopped following an error message by changing its mode with ERR: it displays“ ERR : Dryer t. low ”, the machine stops.Dryer and By-Pass replacementIf the dryer is replaced or has a direct connection (by-pass), it is necessary to disable the dryer functions in the drier menu-accessible through SAV code.The dryer “dew point” temperature acquisition is then disabled, as well as the ON/OFF control.9 - Specific variable speed motorIn certain applications, the motor is equipped with motor temperature control probes.A high motor temperature alarm is activated in order to alert the user about motor overheating.A machine fault – a complete compressor shutdown is triggered when the maximum temperature threshold of the winding is reached (see Operation Incidents).Check the compressor operation ambient temperature and the case internal temperature.____________________________________________________________________________________________________
