Illustration of front panel
（1） 4 character red LED：Display of PV。When we want to key-in a value，the position glittered with this value. If display＝HHHH，it means the present value（PV）is higher than 『SCLH』 ；If display＝LLLL，it means the present value（PV）is lower than 『SCLL』。
（2） 4 character green LED：Display of SV。When we want to key-in a value，the position glittered with this value.SV and percent of PID output are changeable。
（3） Display of output1：Light lamped when output1 is ON。
（4） Display of output2：Light lamped when output2 is ON。
（5） Display of output3：Light lamped when output3 is ON。
（6） Display of communication：It’ll check automatically once every second.（Communicate status between FA1761F and FA3861F），if the status is OK，it glittered with lamp。
（7） Function key：We can change the display mode by pressing this key。
（8） Left key：For input position moving。
（9） Up key：Increase value or function select。
（10） Down key：Reduce value or function select。
（11） Unit：Temperature（FA1761F）-℃；Humidity（FA3861F）-﹪。

Installation place
■Place where an ambient temperature is 0 to 40℃，and relative humidity is 80﹪RH or less。
■Place where no water splash and non-condensing develop。
■Place where no direct sunshine exist。
■Place where is clear and dust or corrosive gas are not present。
■Place where is far from noise-generating devices such as heavy duty solenoid switches and phase control SCRs。
Installation method
■Insert the FA1761F/FA3861F unit from through the cutout on the panel。
■Secure two claws of the mounting brackets to the holes on the side panel of the unit。
■Tighten the screws for the mounting brackets to secure the units。
Power line and ground connections
■The power line and ground connections are made at the FA1761F/FA3861F’s terminal board。
■The FA1761F/FA3861F is designed to operate on 100/110VAC or 200/220VAC 50/60Hz power line。
■Make sure to connect the G（ground）terminal to the earth to minimize external interference。
■For AC100V or AC110V。 ■For AC200V or AC220V。

Initial set
This item contains setting range selection、offset adjust、action mode selection（reverse or direct）。
The initial set display is shown from the normal display by simultaneously pressing the two keys： and for a while，at the same time，PID output＝OFF。
Under this status，It will change by pressing key in sequence as below：
| Display | Name | Function |
| SCLL | Scale Low | The low limit value of setting for Temp. or Humi. |
| SCLH | Scale High | The high limit value of setting for Temp. or Humi. |
| oFFS | Offset Adjust | Range：±5.0。 Example：If deviation value＝+1，input value＝-1。 |
| cycL | Cycle Time | Range：1~30 sec.。 |
| LMTL | Limit Low | The low limit value of PID output。 Range：0~30。 |
| LMTH | Limit High | The high limit value of PID output。 Range：70~100。 |
| PID | PID Zone | The cut point of PID zone。（2 parts） |
| SEt | Set Method | AbSo(Absolute)/DeviationdEU1 selection of output2 and output3。
|
| oPEr | Operate Mode | cont(Control)/ALAr(Alarm) selection of output2 and output3。
|
| out1 | Out1 | HigH(High)/Louu(Low) selection of output1。 |
| out2 | Out2 | HigH(High)/Louu(Low) selection of output2。
（When operate mode＝Alarm，it decided automatically） |
| out3 | Out3 | HigH(High)/Louu(Low) selection of output3。
