1. Wiring
1) Power to the controller. Connect the 85-260V AC power to terminals 9 and
10.
2) Control output connection. Connect terminals 7 and 8 for output.
3) Sensor connection. For thermocouples, connect the positive wire to terminal
4, the negative to terminal 5. For a three-wire RTD with standard DIN color
code, connect the two red wires to terminals 3 and 4, and connect the white
wire to terminal 5. For a two-wire RTD, connect the wires to terminals 4 and 5.
Then, jump a wire between terminals 3 and 4.
2. Set sensor type
Set Sn to 0 for a K type thermocouple (default), 5 for a J type thermocouple,
and 21 for a Pt100 RTD.
3. Switching between automatic and manual mode
Set A-M=1 to active manual mode. Press the A/M key to switch between
automatic and manual mode.
4.Changing the temperature scale from Fahrenheit to Celsius.
Change COOL from 10 to 2 (for heating mode).
5 Setting the controller for cooling control.
For cooling control, set COOL=11 to display Fahrenheit; set COOL=3 to
display Celsius.
6. Setting target temperature (SV)
Press the ▼ or ▲ key once, and then release it. The decimal point on the
lower right corner will start to flash. Press the ▼ or ▲ key to change SV until
the desired value is displayed. The decimal point will stop flashing after no key
is pressed for 3 seconds. You can press the A/M key to move the flashing
decimal point to the desired digit that needs to change. Then press the ▼ or
▲ key to change SV starting from that digit.
7. Auto-tune
You can use the auto-tune function to determine the PID constants
automatically.
There are two ways to start auto-tuning:
1) Set At=2. It will start automatically after 10 seconds.
2) Set At=1. Then during the normal operation, press the A/M key to start the
auto-tune.
The instrument will perform accurate artificial intelligence control after auto
tuning is finished.
7 On/off mode
Set At=0 to active the on/off control mode.
Set the Hysteresis Band parameter Hy to be a desired value.

8. Error Message and trouble shooting

8.1 Display orAL
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.
In this case, the instrument terminates its control function automatically, and
the output value is fixed according to the parameter OUTL. If this happens
when using thermocouple sensor, you can short terminal 4 and 5 with a copper
wire. If the display shows ambient temperature, the thermocouple is defective.
If it still displays orAL, check the input setting, Sn, to make sure it is set to the
right thermocouple type. If the Sn setting is correct, the controller is defective.
For RTD sensors, check the input setting first because most controllers are
shipped with the input set for thermocouples. Then check the wiring. The two
red wires should be connected to terminals 3 and 4. The clear wire should be
connected to terminal 5.
8.2 No heating
When the controller output is set for relay output, the " O U T " LED is
synchronized with output relay. If heat is not output when it is supposed to,
check the OUT LED first. If it is not lit, the controller parameter settings are
wrong. If it is on, check the external switching device (if the relay is pulled-in, or
the SSR's red LED is on). If the external switching device is on, then the
problem is either the external switching device output, its wiring, or the heater.
2011.02
Quick Guide for SYL-2342, 2352
If the external switching device is not on, then the problem is either the
controller output, or the external switch device.
8.3 Poor Accuracy
Please make sure calibration i s done by immersing the probe in liquid.
Comparing the reference in air is not recommended because response time of
the sensor depends on its mass. Some of our sensors have response time
>10 minutes in the air. When the error is larger than 5 °F, the most common
problem is an improper connection between the thermocouple and the
controller. The thermocouple needs to be connected directly to the controller
unless a thermocouple connector and extension wire is used. Copper wire or
a thermocouple extension wire with the wrong polarity connected on the
thermocouple will cause the reading to drift more than 5 °F.
8.4 On on/off mode, although hysteresis is set to 0.3, the unit is running
5 degrees above and below.
If the Hy is very small and temperature changes very quickly, users will need
to consider the delay of the cycle time (the parameter t). For example, if cycle
time is 20 seconds, when the temperature passes the SV+Hy after the
beginning of a 20 seconds cycle, the relay will not act until the start of the next
cycle 20 seconds later. Users may change the cycle time to a smaller value,
such as 2 seconds, to get better precision control.
