Figure 1 Back Terminals Wiring Diagram
4.1 Sensor connection
The default setting for the input type is for K type thermocouple, for different probe type, the parameter Inty
in Table 1.
For thermocouple, connect the positive wire to terminal 9 and the negative wire to terminal 10. For K type
thermocouple, if the wires are red and yellow, the yellow wire is positive. If they are red and other color
(blue, white, green….), the red is positive. If the polarity is reversed, when the temperature goes higher, the
readout will decrease.
For three-wire PT100 probe, if the wire color code is red, red and white (to IEC60751), connect the two red
wires to terminals 9 and 10 respectively, and connect the white wire to terminal 8. For two-wire PT100
probe, connect one wire to terminal 8 and connect the other wire to terminal 9, and short the terminals 9
and 10. The parameter Inty need to be changed to P10.0 (for 0.1 degree display resolution) or P100 (for 1
degree display resolution).
4.2 SSR connection
When the main control output is set to SSR (Outy in Table 1is set to 2 or 3), the SSR output is enabled.
The terminal 6 should be connected to the positive pole of the DC control side of the SSR, the terminal 7
should go to the negative pole of the SSR. When there is no SSR connected to the terminals 6 and 7, there
should be around 8V DC between them when the OUT indicator is on.
4.3 J1, J2 relay connection
J2 relay can be set to PID or on/off control output, or set as an alarm relay (see Outy in Table 1). J1 is for
alarm only. Please note the relays are just a switch, there is no power on them. The power need to be
provided to the load connected to the relays.

Note 4. Psb - Display temperature offset
This feature allows the input value to be changed to agree with an external reference or to compensate for
sensor error. For example, if the measured temperature of the controller is 100 degrees, but the reference
temperature is 98 degrees. By setting the Psb= -2, the PV display of the controller would change to be 98.
To set the negative value for Psb, use the shift key to move the focus digit to the first digit from the left, then
use the down key to change the digit to show the negative symbol.

Note 5. P – Proportional band
The proportional term produces an output value that is proportional to the current error value. A high
proportional gain results in a large change in the output for a given change in the error. If the proportional
gain is too high, the system can become unstable. In contrast, a small gain results in a small output
response to a large input error, and a less responsive or less sensitive controller. If the proportional gain is
too low, the control action may be too small when responding to system disturbances. In a real system,
proportional-only control will leave an offset error in the final steady-state condition. Integral action is
required to eliminate this error.
Note 6. I – Integral time
The contribution from the integral term is proportional to both the magnitude of the error and the duration of
the error. The integral in a PID controller is the sum of the instantaneous error over time and gives the
accumulated offset that should have been corrected previously. The accumulated error is then multiplied by
the integral gain and added to the controller output. The integral term accelerates the movement of the
process towards set point and eliminates the residual steady-state error that occurs with a pure proportional
controller. However, since the integral term responds to accumulated errors from the past, it can cause the
present value to overshoot the set point value.
Note 7. d – Derivation time
The derivative of the process error is calculated by determining the slope of the error over time and
multiplying this rate of change by the derivative gain. The magnitude of the contribution of the derivative
term to the overall control action is termed the derivative gain. Derivative action predicts system behavior
and thus improves settling time and stability of the system. An ideal derivative is not causal, so that
implementations of PID controllers include an additional low pass filtering for the derivative term, to limit the
high frequency gain and noise. Normally dis set to 25% of the Ivalue.
Note 8. SouF – Overshoot suppression factor
Overshooting and undershooting are restricted by the SouF and increase of the parameter can suppress
the overshooting
Note 9. Proportional cycle
It’s the cycle time to switch the output on/off. Within the cycle t time, the output will turn on and off once. For
SSR, in general the cycle time is set to 2 seconds. For mechanical relays, set the cycle time to a higher
value to save the life time of the relay.
Note 10. Filt – digital filter factor
6

GL102B USER’S GUIDE GOLANDERUSA.COM
The filter is to increase the measured temperature display stability, but will delay the response. When Filt is
set to 0, the filter is disabled. 1, 2 and 3 are weak, medium and strong, respectively.
8Auto tune
For PID control mode, if the control with default P, Iand dparameters settings are not able to hold the
target temperature, the built-in auto tune function can find the right PID parameters for the system. When on
heating mode, it will heat up the system to the target temperature then let the system cool down. It will
repeat this process for about 3 times, then the controller will calculate the parameters automatically.
To activate the auto tune function, press and hold the >key until the “AT” indicator starts to blink. When
auto tune process finished, the “AT” indicator will stop blinking. The new values for parameters P, Iand d
are calculated by the controller.
To stop the auto-tuning, press and hold >key for 3 seconds, until “AT” indicator stops blinking. The PID
parameters values will not change.
Please note:
•Auto tune from time to time, there will be a significant temperature overshoot, please lower SV value
to prevent accident.
•The sensor, load (heater…) need to be connected properly, otherwise, the auto tune will not
complete.
•The time for the auto tune depends on the system response time, would be from a few minutes to
hours.
•Only need to run auto tune one time.

Note 11. The SV value can be set by accessing the 0001 menu. Or, when in normal operation mode, use
the UP or DOWN key to change the SV directly.
Note 12. When the J1 (J2) relays are set as alarm, the relay will be controlled by the two parameters AH1
(AH2) and AL1 (AL2). The alarm can be set as high alarm or low alarm.
For high alarm, set AH1 (AH2) > AL1 (AL2). When the temperature increase to AH1 (AH2), the J1 (J2)
relay will be closed (alarm on), when the temperature drops down to AL1 (AL2), the J1 (J2) relay will be
open (alarm off).
For low alarm, set AH1 (AH2) < AL1 (AL2). When the temperature decrease to AH1 (AH2), the J1 (J2)
relay will be closed (alarm on), when the temperature increases to AL1 (AL2), the J1 (J2) relay will be open
(alarm off).

10 Manual Control Mode
User can switch the control mode from PID mode to manual mode. Manual mode allows user to adjust the
output percentage manually. The output will remain the set percentage regardless what the measured
temperature is. For example, if the cycle time is 2 seconds, output percentage is set to 75, then in every 2
seconds, the output will be on for 1.5 seconds and will be off for 0.5 seconds. To switch from PID mode to
manual mode, press and hold the SET key until the AT indicator turns on. The PV window of the controller
will still show the measured temperature, the first digit of the SV window will show a letter “M”, which means
the controller is in manual mode. The right 3 digits of the SV window will show the output percentage. User
can use the UP/DOWN key to change the percentage manually. To switch back to PID mode, press and
hold the SET key until the AT indicator turns off.
11 Examples
11.1 Control a 12V DC fan for BBQ Smoker
The DC fan draws about 0.3A current. Use J2 relay to control the fan directly. To use PID mode to control
the fan, set outy=1, set cycle time ot=15 seconds to save the lifetime of the relay and the fan. Set the SV to
the desired temperature you want to hold, for example, SV=350 °F.

To use a PT100 probe and a heater to keep the temperature to 200°F, keep the output setting for PID
control mode, outy=2; set input type for PT100, Inty=P10.0; set target temperature SV=200.
Note: For 220V heater, change the AC power source to 220V AC, use hot line 1 (L1) and hot line 2 (L2) to
power the heater.
11.4 Control a 220V AC Heater via Contactor
If heater draws more than 3A, the J2 relay could not handle it directly. A 220V coil contactor can be used to
power the heater.
1) To use PID mode to control the heater, set outy=1, set cycle time ot=15 seconds to save the lifetime of
the J2 relay and contactor. Set the SV to the desired temperature you want to hold, for example, SV=350°F.
2) To keep the temperature in a range, for example, 330-350°F, set the output control to on/off mode,
outy=4; keep the cycle time setting ot=2. Set SV=350, Hy=20. The output will be off when temperature goes
above 350°F, and will be on again when temperature drops down to SV-Hy=320 °F.

11.5 Use J1 Relay to Trigger a 12V DC Alarm Buzzer
J1 relay is controlled by parameters AH1 and AL2.
1) High alarm: If you want the buzzer to be on when temperature is higher than 210°F, and to be off when
temperature drops down to 205°F, set AH1=210, AL1=205 (AH>AL).
2) Low alarm: If you want the buzzer to be on when temperature is lower than 5°F, and to be off when
temperature goes back to 10°F, set AH1=5, AL1=10 (AH<AL).
3) When the J2 relay is set to alarm (Outy=0, 2 or 3), the setting is similar to J1 relay.
