(In order to prevent unnecessary trip by occasional factors, a 5-second delay is designed.)

6．手动启动关闭风机功能：按风机键，风机启动，再按风机键，风机关闭。如手动风机启动后没有手动关闭风机，则风机启动约15分钟后自动关闭。

Manual fan starting and stopping function: Pressing the fan button, the fan will start up, pressing the fan button again, the fan will stop. When the fan is manually started, it will stop automatically after about 15 minutes if it is not stopped manually.

7．风机定时检测功能：为避免风机长时期不启动而锈蚀堵转损坏，特设有风机定时检测功能，定时启动时间可自由设定范围为0-199小时，到设定值时风机启动一次，启动时间约2分钟。输入“000”时则取消该功能。

Periodic fan detection function: In order to prevent long time stopping and the consequential corrosion and blockage, a special fan detection function is provided, the selectable scope of the periodic starting time is from 0 to 199 hours, when the time reaches the preset starting value, and the fan will start up automatically and keep running for about 2 minutes. Inputting “000” will cancel the function.

8．控制功能自检：可模拟输入温度值而使温控器作出相应的功能表现。

Control function self diagnose: You can input analog temperature value, and let the thermostat performs corresponding functions.

9．“黑匣子”功能：可记录温控器断电时的变压器三相绕组温度，以及本机的工作状态。 “Back box” function: The thermostat can record the temperature value of the three-phase windings in the transformer in case of power failure.

10．所有温度设置均可通过面板上的轻触键直接设置。为避免闲杂人员随意更改设置，温控器设有密码，只有密码输入正确才能设置，否则只能查看而不能设置，并且温控器发出一声?嘀?的报警声。设置温度范围见下表。

All the temperature values can be set with the touch buttons on the control panel. In order to prevent irrelevant people to change the set values, the thermostat is design to use password, you can set the value only when you input the correct password, otherwise, you can only see the value and cannot change it, if you do not input correct password, the thermostat will gave out an alarm sound. The scope of the setting temperature value is shown in the following table. 温度T 出厂设定温度（℃） 可调温度范围（℃） Temperature T Factory set temperature(℃) Adjustable temperature scope(℃) 风机关闭温度T1 80 0～200 Fan stop temperature T1 风机启动温度T2 100 0～200 Fan start temperature T2 超温报警温度T3 150 0～200 Over heat alarm temperature T3 超温跳闸温度T4 180 0～200 Over heat trip temperature T4 注：1、设置时应遵循T4>T3>T2>T1+4 （4为风机启停的最小回差值） 2、出厂设定温度值可根据用户的需求来设定。 Note：1. To set, follow the procedure: T4>T3>T2>T1+4 （4 is the minimum return difference for fan start and stop）

2. The factory set temperature value can be made according to customers? requirement.

四、温控器工作状态Thermostat working state

1．LED显示变压器三相绕组中温度最大值时，“最大”指示灯亮。

When LED displays the maximum temperature value of the three-phase windings in the

transformer, the “Maximum” indicator lamp is lit.

2．LED巡回显示变压器三相温度值时，“巡回”指示灯亮。

When LED alternately displays the temperature values of the three-phase windings in

the transformer, the “Alternating” indicator lamp is lit.

3．风机运行：“风机”指示灯亮，控制风机继电器触点闭合，风机启动。

Fan Run: “Fan” indicator lamp is lit, the fan relay contact is closed, and the fan is

started.

4．超温报警：“超温”指示灯亮，温控器内发出?嘀嘀?声，超温报警继电器触点闭合。 Overheat alarm: “Overheat” indicator lamp is lit, the thermostat gives an alarm sound,

and the overheat alarm relay contact is closed.

5．超温跳闸：“跳闸”指示灯亮，超温跳闸继电器触点闭合。

Overheat trip: “Trip” indicator lamp is lit, and the overheat trip relay contact is

closed.

6．A、B、C三相传感器故障时相应A、B、C指示灯亮，同时控制风机继电器触点闭合，风机启动及温控器内发出?嘀嘀?声，并且超温报警继电器触点闭合。温控器显示?X-HO? 或?X-LO?，?X?表示故障相位。显示?HO?时为传感器+线断或传感器内部开路。显示?LO?时为传感器G或-线断或传感器内部短路，也可能未接传感器（传感器+，-，G线请参考传感器内部接线图）。

When the sensor of phase A, B or C has a trouble, the corresponding indicator lamp A, B or C is lit, at the same time, the fan control relay contact is closed, the fan is started, the thermostat will give out a alarm sound, and the overheat alarm relay contact is closed. The thermostat displays ?X-HO? or ?X-LO?，?X? indicates trouble phase. When ?HO? is displayed, it indicates sensor + wire broken, or the sensor is internally open. When ?LO? is displayed, it indicates sensor G, or -wire broken, or the sensor is internally short circuited, or the sensor is not connected (about sensor +, -，G wire, please refer to the internal wiring diagram of the sensor). 五、按键功能Functions of the keys

1、功能键：正常工作状态时按此键可进入参数设置状态；参数设置状态时按此键将设

置参数写入，并进入下一参数设置；“黑匣子”记录检查状态时按此键可结束检查记录状态，并进入正常工作状态。功能检测状态时按此键返回正常工作状态。

Function key: During normal work state, pressing this key will enter into parameter setting mode; in parameter setting mode, pressing this key will enter into parameter writing modem and at the same time it will enter into the next parameter setting; in “black box” record checking mode, pressing this key will stop the record checking mode and enter into the normal work state. During function diagnose mode, pressing this key will return back to normal work state.

2、移位/风机键：正常工作状态时按此键可手动启停风机；参数设置状态时按此键可改变设置闪烁位。“黑匣子”记录检查状态时按此键无效。 Shift/Fan key：During normal work state, pressing this key can manually start or stop the fan; in parameter setting mode, pressing this key can change the setting flicker bit. In “black box” record checking mode, this key is unavailable.

3、增加/巡回键：正常工作状态时按此键可切换最高/巡回显示状态。参数设置状态时按此键一次可使设置闪烁位数据增加?1?。依此类推。“黑匣子”记录检查状态时按此键无效。

Increase/Alternating：During normal work state, pressing this key can change to Maximum/Alternating mode; in parameter setting mode, pressing this key once will increase the setting flicker bit by “1”, and the like. In “black box” record checking mode, this key is unavailable.

4、记录键：正常工作状态时按此键可进入“黑匣子”记录检查状态。参数设置状态时按此键无效。“黑匣子”记录检查状态时连续按此键可将全部记录检查完，并进入正常的工作状态；功能检测状态时按此键可将模拟温度值输入温控器，温控器作相应的功能表现（为防止误跳闸，模拟输入温度值大于或等于设定超温跳闸温度值时，温控器不发出跳闸信号，仅面板上跳闸指示灯亮）。

Record key：During normal work state, pressing this key will enter into “black box” record checking mode. In parameter setting mode, this key is unavailable. In “black box” record checking mode, pressing this key repeatedly will check through all the records and then enter into normal work state. in function diagnose mode, pressing this key can input the analogue temperature value into the thermostat, and the thermostat will perform corresponding functions（To avoid mistrip, the analogue temperature value should be larger or equal than the preset trip temperature value, the thermostat will not give out trip signal, only the trip indicator lamp on the control panel is lit）.

5、超高温自动跳闸功能：当三相绕组中有一相达到设定的跳闸温度值时，温控箱接通跳闸输出端子，并提供一个开关信号给远方的控制柜，启动跳闸电路。（为防止因偶然因素触发跳闸特设有约40S延时）

5. Superhigh temperature automatic trip function：If the temperature of one of the three-phase windings reaches the set trip value, the temperature control box will connect the trip output terminal, and provide a switching signal to the remote control cabinet so as to trigger the trip circuit.（In order to prevent accident trip, a delay of 40S is designed）

6、消音键：温控箱内出现消防报警声音时，按此键可消除声音。如果没有发生超温报警或故障时，此键恢复到开机状态。

7、在任何操作状态下，如超过20秒未操作，温控器将自动返回正常工作状态。

No matter in any mode, if there is no operation for more than 20 seconds, the thermostat will automatically return to the normal work state. 六、BWD3K130C电脑通讯功能
