• OUT1 : Limit control output

• A1 : Alarm 1 (A1) output

• TRANSMIT : Transmission output

• EXT.RESET: External reset input

• RS-485 : Serial communication (C5 option)

• DC

: DC current, DC voltage input For DC current input,

onnect 50 shunt

resistor between input

terminals.

• TC : Thermocouple input

• RTD : Resistance temperature detector input

Notice

• The terminal block of the JCD-33A is designed to be wired from the left side. The lead wire must be inserted from the left side of the te rminal, and fa stened by the terminal screw.

• Use a thermocouple and compensating lead wire that correspond to the sensor input

specification of this controller.

• Use the 3-wire RTD which corresponds to the input specification of this controller.

• This controller does not have built-in power switch, circuit breaker or fuse. Therefore, it is

necessary to install them in the circuit near the external controller. (Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)

• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).

• For the OUT1 (Limit control output terminals 5-6), externally use a relay according to the

capacity of the load to protect the built-in relay contact.

• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires

to avoid external interference.

• Do not apply a commercial power source to the sensor connected to the input terminal nor

allow the power source to come into contact with the sensor.

Alarm type

(High limit alarm) : The alarm action is deviation setting from the SV. The alarm is

activated if the PV (process variable) reaches the high limit set value.

(Low limit alarm) : The alarm action is deviation setting from the SV. The alarm is

activated if the PV (process variable) goes under the low limit set value.

(High/Low limits alarm): Combines High limit and Low limit alarm actions. When PV (process variable) reaches high limit set value or goes under the low limit set value, the alarm is activated.

(High/Low limit range alarm): When PV (process variable) is between the high limit set value and low limit set value, the alarm is activated. If PV exceeds the high limit set value or goes under the low limit set value, the alarm output is turned off.

(Process high alarm) Within the scale range of the controller, alarm action points

(Proces s l ow a l a rm ) can be set at random and if the PV (process variable) reaches the randomly set action point, the alarm is activated.

(High limit alarm with standby) When the power to the controller is turned on, even if

(Low li mi t a la r m w it h s t an d by ) the PV (process variable) enters the alarm action range,

(High/L ow l im i t s w it h s t a n db y ) the alarm is not activated. Even if the PV enters the alarm action range due to SV change during running,

the alarm is not activated, either. If the controller is allowed to keep running, once the input exceeds the alarm action point, the standby function will be released.

Sensor correction function

This corrects the input value from the sensor. When a sensor cannot be set at a location where control is desired, the sensor measuring temperature may deviate from the temperature in the controlled location. When controlling with plural controllers, sometimes the measured temperatures (PV) do not concur due to differences in sensor accuracy or dispersion of load capacities. In such a case, the control can be set at the desired temperature by adjusting the input value of sensors.

Energized/Deenergized

When A1/A2 Energized is selected, the A1/A2 output (between terminals 7-8, or 12-13) is conducted (ON) while the A1/A2 output indicator is lit. The A1/A2 output is not conducted (OFF) while the A1/A2 output indicator is not lit.

When A1/A2 Deenergized is selected, the A1/A2 output (between terminals 7-8, or 12-13) is not conducted (OFF) while the A1/A2 output indicator is lit. The A1/A2 output is conducted (ON) while the A1/A2 output indicator is not lit.
