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 K type thermocouple. Set Sn to the right sensor code
if another sensor type 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 3 and 4. The white wire should be connected
to terminal 5. For a two-wire RTD, the wires should be connected to terminals
4 and 5. Jump a wire between terminals 3 and 4. Set controller input type, Sn
to 21.

3.1.3 Linear input (V or mA)
Voltage and mA current signal inputs should be connected between terminals
2 and 5. Terminal 2 is positive.

3.2 Power to the controller

The power cables should be connected to terminals 9 and 10. Polarity does
not matter. It can be powered by 85- 2 6 0 V AC power source. Ne i t h e r 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 hot wire
to terminal 9 and neutral to 10.

3.3 Control output connection

The SSR control output of the controller SYL-2352 provides a 12V DC signal
that can control up to 5 SSRs in parallel. The r e lay o utpu t of the controller
SYL-2342 can be used to turn on a contactor or a solenoid valve. It can drive
a small heater directly if the heater draws less than 10 Ampere when
connected to 120V AC power source. For applications needing two control
outputs, such as one for heating and another for cooling, relays AL1 or AL2
can be used for the second output with on/off control mode. Please see
Figure 11 for details.

3.3.1 Connecting the load through SSR (for SYL-2352)
Connect terminal 7 to the positive input and terminal 8 to the negative input of
the SSR. See Figure 8 and 9 for details.

3.3.2 Connecting the load through a contactor (for SYL-2342)
Assuming the controller is powered by 120V AC and the contactor has a 120V
AC coil, jump a wire between terminals 8 and 9. Connect terminal 7 to one
lead of the coil and terminal 10 to the other lead of the coil. Please see Figure
7 for example.

3.3.3. Connecting the heater (or cooler) directly from the internal relay
Assuming the controller and the load (heater or cooler) are powered by the
same voltage. Jump a wire from terminal 9 to 8. Connect terminal 7 to the one
lead of the load and terminal 10 to the other lead of the load. Please see
Figure 6 and 11 for details.

3.4 For first time users without prior experience with PID con trollers, the
following notes may prevent you from making common mis take s.

3.4.1 Power to the heater does not flow through terminal 9 and 1 0 of the
controller. The controller consumes less than 2 watts of power. It only
provides a control signal to the relay. Therefore, wires in the 18 to 26 gauge
range should be used for providing power to terminals 9 and 10. Thicker wires
may be more difficult to install.

3.4.2 The control relay outputs (for SYL-2342), -AL1 and AL2, are “dry” single
pole switches. They do not provide power by themselves. Please see Figure
6, 7 and 11 for how they are wired when providing a 120V output ( o r when
output voltage is the same as the power source for the controller). If the load
of the relay requires a different voltage than that for the controller, another
power source will be needed. See Figure 10 for examples.

3.4.3 SSR output power does not come from the input of the SSR. The output
of the SSR is a single pole switch between terminals 1 and 2 of the SSR. The
input of the SSR is for control, or triggering the SSR. (Please note we are
talking about the SSR itself, not the SSR control output of the controller).
When switching a North American 240V AC power, the heater will be live
even when the SSR is off. Users should install a double pole mechanical
switch to the power input.

3.4.4. For all controller models listed in this manual, the power is controlled by
regulating the duration of on time for a fixed period of time. It is not controlled
by regulating amplitude of the voltage or current. This is often referred as time
proportional control. e.g. If the cycle rate is set for 100 seconds, a 60% output
means controller will switch on the power for 60 seconds and off for 40
seconds (60/100=60%). Almost all high power control systems use time
proportional control because amplitude proportional control is too expensive
and inefficient.

until the parameter setup menu is displayed (display mode 3). Please refer to

4.3 for how to set the parameters.

4.3 Setup flow chart

While in the parameter setup mode, use ▲ and ▼ to modify a digit and use
A/M to select the digit that needs to be modified. Press the A/M and SET key
at the same time to exit the parameter setup mode. The instrument will
automatically exit if no key is pressed for 10 seconds. Figure 4 is the setup
flow chart.
Pleas e no te t he changed parameter will be automatically registered without
pressing the SET key. If the controller is locked ( see 4.17 ) , only limited
parameters (or no parameters) can be changed.

4.4.1 Alarm parameters

This controller offers four types of alarm, “ALM1”, “ALM2”, “Hy-1”, “Hy-2”.

ALM1: High limit absolute alarm. If the process value is greater th an the
value specified as “ALM1+Hy” (Hy is the Hysteresis Band), then the alarm
will turn on. It will turn off when the process value is less than “ALM1-Hy”.

ALM2: Low limit absolute alarm. If the process value is less than the value
specified as “ALM2-Hy”, then the alarm will turn on, and the alarm will turn
off if the process value is greater than “ALM2+Hy”.

Hy-1: Deviation high alarm. If the temperature is above “SV+Hy-1 +Hy”,
the alarm will turn on, and the alarm will turn off if the process value is less
than “SV+Hy-1 -Hy” (we will discuss the role of Hy in the next section)

Hy-2: Deviation low alarm. If the temperature is below “SV-Hy-2 -Hy”, the
alarm will turn on, and the alarm will turn off if the temperature is greater
than “SV-Hy-2 +Hy”.
