• No flammable, explosive gases
• Few mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of -10 to 55 (14 to 131 ) that does not change rapidly, and no icing
• An ambient non-condensing humidity of 35 to 85 %RH
• No large capacity electromagnetic switches or cables through which large current is flowing.
• No water, oil, chemicals or the vapors of these substances can come into direct contact with the controller

Mounting to, and Removal from the Control Panel

How to mount the BCS3

• Mount the controller vertically to a flat, rigid panel. Mountable panel thickness: 1 to 5 mm

1. Insert the controller from the front side of the panel. (Fig. 3.4-1)
2. Insert the mounting frame until it comes into contact with the panel, and fasten with screws. Tighten screws with one rotation upon the screw tips touching the panel.
3. The torque is 0.05 to 0.06 N•m. (Fig. 3.4-2) [Mounting frame screws are included only when Drip-proof/Dust-proof (IP option) is ordered.]

How to remove the mounting frame and the BCS3 (Fig. 3.4-3)

1. Turn the power to the unit OFF, and disconnect all wires before removing the mounting frame and unit.
2. Insert a flat blade screwdriver between the mounting frame and unit .
3. Slowly push the frame upward using the screwdriver , while pushing the unit toward the panel
4. Repeat step (2) and slowly push the frame downward using the screwdriver for the other side. The frame can be removed little by little by repeating these steps.

Wiring

Warning

• Turn the power supply to the instrument OFF before wiring or checking. Working on or touching the terminal with the power switched on may result in severe injury or death due to electrical shock.

Caution

• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be inserted from the left side of the terminal, and fastened with the terminal screw. The torque should be 0.63 N•m.
• To extend a thermocouple’s lead wire, be sure to use a compensating lead wire in accordance with the sensor input specifications. (If any other compensating lead wire is used, a temperature indication error may be caused.)
• Use the 3-wire RTD in accordance with the sensor input specifications of this controller.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It is necessary to install a power switch, circuit breaker and fuse near the controller. (Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• When using a relay contact output type, externally use a relay in accordance with the capacity of the load.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from controller AC sources or load wires.

Terminal Arrangement

• POWER SUPPLY: 100 to 240 V AC
• EV1: Event 1 (A1) output (SA option)
• EV2: Event 2 (A2) output (SA option)
• OUT: Control output
• TC: Thermocouple input
• RTD: RTD input

Lead Wire Solderless Terminal

• Use a solderless terminal with an insulation sleeve in which an M3 screw fits as shown below. The torque should be 0.63 N•m.

Solderless Terminal	Manufacturer	Model	Tightening Torque
Y-type	NICHIFU TERMINAL INDUSTRIES CO., LTD.	TMEX1.25Y-3	0.63 N•m
	J.S.T.MFG.CO.,LTD.	VD1.25-B3A
Ring-type	NICHIFU TERMINAL INDUSTRIES CO., LTD.	TMEX1.25-3
	J.S.T.MFG.CO.,LTD.	V1.25-3

Operation Flowchart

• Indication after the power is turned on After the power is turned ON, the PV Display indicates the input type characters and temperature unit, and the SV Display indicates the input range high limit value for approximately 3 seconds. See (Table 5-1).

• During this time, all outputs and the LED indicators are in OFF status.
• Control will then start, indicating the PV (process variable) on the PV Display, and SV (desired value) on the SV Display.
• While the Control output OFF function is working, the PV Display indicates oFF.
• To cancel the Control output OFF function, press the key for approximately 3 seconds.

Alarm 1 (A1), 2 (A2) Action

A1: Alarm 1

• For Alarm 2 (A2), Read “A2” for “A1”.

Loop Break Alarm

• The alarm will be activated when the PV does not rise as much as, or more than the band within the time it takes to assess the loop break alarm after the output manipulated variable has reached 100% or the output high limit value. The alarm will also be activated when the PV does not fall as much as, or more than the band within the time it takes to assess the loop break alarm after the output manipulated variable has reached 0% or the output low limit value.
• For the Direct (Cooling) control action, read “fall” for “rise” and vice versa.

Characters Used in this Manual:

Operation

• After the unit is mounted to the control panel and wiring is completed, operate the unit following the procedure below.

1. Turn the power supply to the BCS3 ON.
2. Input each set value. Refer to “5. Operation Flowchart”.
3. Turn the load circuit power ON. Control action starts so as to keep the control target at the SV (desired value).

Basic Settings

• Basic setting method for the Main Setting Mode and AT Perform/Cancel are described below. Upper characters indicate setting item characters on the PV Display.
• Lower characters indicate factory default value on the SV Display.

Main Setting Mode (When setting SV to 100 )

Enter the Main Setting Mode.

• Press the key in the PV/SV Display Mode. The unit enters the Main Setting Mode.

Set SV (desired value).

• Set SV with the or key.

Register the SV.

• Register the SV by pressing  the  key. The unit reverts to the PV/SV Display Mode.

Control starts.

• Control starts so as to keep the measuring temperature at 100 .

AT Perform/Cancel (in PID control)

Enter the Sub Setting Mode. 

• Press the key while pressing the key in the PV/SV Display Mode.
• The unit enters the Sub Setting Mode.

Select AT/Auto-reset Perform/Cancel. 

• Select “AT Perform” with thekey or select “AT Cancel” with the key

Confirm AT Perform/Cancel. 

• Press the key. The unit reverts to the PV/SV Display Mode.

AT Perform/Cancel 

• While AT is performing, the AT indicator flashes. It goes off if AT is cancelled.
• In order to decide each P, I, D value automatically, the auto-tuning (AT) process has been made to fluctuate in order to achieve an optimal value.
• Sometimes the auto-tuning (AT) process will not fluctuate if auto-tuning is performed at or near room temperature. Therefore auto-tuning (AT) may not finish normally.
• Auto-reset is available for P or PD control action. Auto-reset is cancelled in approx. 4 minutes. It cannot be released while performing this function.
