Instruction Manual

10.2 A 24V DC solenoid valve is switched by J2 relay in On/off mode. The

valve will be on until temperature reaches 105 °F. Then, it will shut off. When

the temperature drops to below 100 °F, it will be on again. The power source

is 24V DC. A K type thermocouple is used as the temperature sensor.

b. Parameter setting. These are the parameters that need to be changed

from the initial value: outy=4 for On/Off mode with J2 relay output; Hy =5

degree, SV=105 °F for the target temperature.

10.3 A BBQ smoker needs to be controlled at 200°F. The power source is

12 V D C . A K type thermocouple is used as the temperature sensor. The

system consists of a 12V DC fan, a K type thermocouple.

b . Parameter setting. These are the parameters that need to be changed

from the initial value: outy=1 for PID mode with relay output; ot= 1 0 , the

reason we set the cycle time at 1 0 is that the fan needs time to start;

SV=250 °F for the target temperature. Following are the tuning parameters

that we found wor k best for this type of application. P=1.2, I=300, d=70,

SouF=0.7

11. Error Message and trouble shooting

11.1 Display EEEE

This is an input error message. The possible reasons are, the sensor is not

connected correctly; the input setting is wrong type; or the sensor is defective.

If this happens when using thermocouple sensor, you can short terminals 9

and 10. If the display shows the ambient temperature, the thermocouple is

defective. If it still displays EEEE, check the input setting, Inty, to make sure it

is set to the right thermocouple type. If Inty setting is correct, the controller is

defective. For RTD sensor, check the input setting first because most

controllers are shipped with input set for thermocouple. Then check the wiring.

The two red wires should be on terminals 9 and 10. The clear wire should be

on terminal 8.

11.2 No heating

When controller output is set for relay output, the "AL2" LED is synchronized

with output relay. When controller output is set for SSR output, the "OUT" LED

is synchronized with SSR control output. If there is no heat when it is

supposed to, check the AL2 or OUT first. If it is not lit, the controller parameter

setting is wrong. If i t is on, check external switching device (if the relay is

pulled-in, or the red LED of the SSR). If the external switching device is on,

then the problem is either the external switching device output, its wiring, or

the heater. If the external switching device is not on, then the problem is either

24V DC

the controller output, or the external switch device.

11.3 Poor Accuracy

Please make sure calibration is done by immersing the probe in liquid.

Comparing with reference in air is not recommended because response time

of sensor depends on its mass. Some of our sensor has response time >10

minutes in the air. When the error is larger than 5°F, the most common

problem is improper connection between the thermocouple and the controller.

The thermocouple needs to be connected directly to the controller unless a

thermocouple connector or an extension wire is used. A copper connector,

copper wire, or thermocouple extension wire with wrong polarity connected on

the thermocouple will cause the reading drift more than 5°F.
