SWA-2441B PID TEMPERATURE CONTROLLER INSTRUCTION MANUAL
1. Caution
• This controller is intended to control equipment under normal operating
conditions. If failure or malfunction of the controller may lead to abnormal
operating conditions that may result in personal injury or damage to the
equipment or other property, devices (limit or safety controls) or systems
(alarm or supervisory) intended to warn of or protect against failure or
malfunction of the controller must be incorporated into and maintained as
part of the control system.
• Installing the rubber gasket supplied will protect the controller front panel
from dust and water splash (IP54 rating). Additional protection is needed for
higher IP rating.
• This controller carries a 90-day limited warranty. This warranty is limited to
the controller only.

3. Terminal Assignment
Note: Use a wire or a N.C. switch to jump pin 11 and 12 together to enable the
timer.
3.1 Sensor Connection
Please refer to table 3 for the input sensor type (Sn) setting codes. The initial
setting for input is for a type K thermocouple. Set Sn to the correct sensor code if
another type of sensor is used.
3.1.1 Thermocouple
The thermocouple should be connected to terminals 4 and 5. Make sure that the
polarity is correct. There are two commonly used color codes for the K type
thermocouple. US color code uses yellow (positive) and red (negative). Imported
DIN color code uses red (positive) and green/blue (negative). The temperature
reading will decrease as temperature increases if the connection is reversed.
When using ungrounded thermocouple that is in touch with a large conductive
subject, the electromagnetic field picked up by the sensor tip might be too large
for the controller to handle, the temperature display will change erratically. In that
case, connecting the shield of thermocouple to terminal 5 (circuit ground of the
controller) might solve the problem. Another option is to connect the conductive
subject to terminal 5.
3.1.2 RTD sensor
For a three-wire RTD with standard DIN color code, the two red wires should be
connected to the terminals 4 and 5. The white wire should be connected to
terminal 3. For a two-wire RTD, the wires should be connected to terminals 3 and
4. Jump a wire between terminals 4 and 5. Set controller input type Sn to Pt.
3.2 Power to the Controller
The power cables should be connected to terminals 6 and 7. Polarity does not
matter. It can be powered by 120V or 240VAC power source. Neither a
transformer nor jumper is needed to wire it up. For the sake of consistency with
the wiring example described later, we suggest you connect the neutral wire to
terminal 6 and hot to 7.
3.2.1 Timer Reset terminals
Terminals 11 and 12 are for connecting a reset switch. If you need to start the
timer after controller is powered up, you should short these two terminals
together with a jumper wire. To use the reset function, these terminals should be
connected to a switch. Open the contact of the switch will rest the timer. Close
the contact of the switch will start the timer. Some applications may need a N.O.
