SOLO Temperature Controller
SL4848 Series

SOLO

AutomationDirect’s SOLO is a single loop dual output temperature controller that can control both heating and
cooling simultaneously. There are four types of control modes: PID, ON/OFF, Manual, and Ramp / Soak control.
Depending upon the particular model of controller, the available outputs include relay, voltage pulse, current,
and linear voltage. There are up to three alarm outputs available to allow seventeen alarm types in the initial
setting mode. SOLO can accept various types of thermocouple, RTD, or analog inputs, and has a built in RS-485
interface using Modbus slave (ASCII or RTU) communication protocol.

Other features include:

• 1/16 DIN panel size

• 2 line x 4 character 7-segment LED display for Process Value (PV): Red color, and Set Point (SV): Green color

• Auto Tuning (AT) function with PID control

• Selectable between °C and °F for thermocouple or RTD inputs

• 0 to 50 °C (32 to 122 °F) operating temperature range

• UL, CUL and CE agency approvals

WARNING! Electric shock danger

1. To prevent electric shock, do not touch the AC terminals while the power is supplied to the controller.

This controller is an open-type temperature controller. Make sure to evaluate any dangerous application in
which a serious human injury or serious property damage may occur.

1. Always use recommended solder-less terminals: Fork terminal with insolation (M3 screw, width is 7.0mm, hole
diameter 3.2mm). Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Recommended tightening torque: 0.4 Nm
(4kgfcm). Applicable wire: Solid/twisted wire of 2 mm, 12AWG to 24AWG. Choose AutomationDirect part numbers
BM-00120, BM-00220 or BM-00320 depending on wire size. Be sure to tighten them properly.

2. Protect the controller from dust or foreign objects to prevent controller malfunction.

3. Do not modify or disassemble the controller.

4. Do not connect anything to the “Not used” terminals.

5. Make sure all wires are connected correctly.

6. Do not install and/or use the controller in places subject to: (a) Dust or corrosive gases and liquid (b) High humidity
(c) Vibration and shock (d) EMI / RFI (e) high temperature.

7. Turn power off when wiring or changing a temperature sensor.

8. Be sure to use wires that match the thermocouple types when extending or connecting the thermocouple wires.

9. Use wires with correct resistance when extending or connecting a platinum resistance thermometer (RTD).

10. Keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and

route power wires as far as possible from load wires to prevent interference and induced noise.

11. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity,

dripping water, corrosive materials, airborne dust and electric shock or vibration.

12. Make sure power cables and signals from instruments are all installed properly before energizing the controller,

otherwise serious damage may occur.

13. To prevent electric shock, do not touch the terminals in the controller or try to repair the controller when power

is applied.

14. Use a soft, dry cloth to clean the controller. Do not use acid or alkaline liquids for cleaning.

15. This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required,

install the protection close to the instrument. Recommended fuse rating: Rated voltage 250 V, Rated current 1
A. Fuse type: Time-lag fuse

16. Note: This controller does not provide overcurrent protection. Use of this product requires that suitable overcur -

rent protection device(s) must be added to ensure compliance with all relevant electrical standards and codes.
(Rated 250 V, 15 Amps max). A suitable disconnecting device should be provided near the controller in the
end-use installation.

communication. The user can monitor the temperature changes of the
controllers from the “PV Monitor” Display.

Reset to Factory Default Instructions

Mounting Instructions

SOLO temperature controllers can be mounted through a cutout in an enclosure or panel by using the dimen­sions shown in Section 5. The directions for mounting the controller through a cutout are:

1. Insert the temperature controller through the panel cutout.

2. Slide the M3X0.5 nut into the opening in the top of the mounting bracket and insert the M3X0.5 X 30mm
mounting screw in the mounting bracket.

3. Insert the mounting bracket into the mounting groove at the top and bottom of the controller, and push the
mounting bracket forward until the bracket stops.

4. Tighten top and bottom screws evenly to secure temperature controller in place.

The SOLO temperature controller has three function modes: Initial Setting mode, Operation mode and Regulation
mode. When power is first applied to the temperature controller, the module information splash screen appears.
This screen shows the firmware version on the PV display and the two output types for that particular model on
the SV display. After three seconds, the controller will automatically proceed to the Operation mode main screen.
Press and hold the ; button for three seconds to go into the Initial Setting mode. Press the ; button for less
than three seconds to access the Regulation mode. Press the • button while inside any of the three function
modes to access the individual parameters for each function mode. Use the . and , buttons to change the
individual parameter values. Pressing the ; button saves the parameter values. Press the ; button again
to return the controller to the Operation mode.

1. Access the Initial Setup mode by pressing and holding the ; button for three seconds. In the parameter

inpt

, use the , and . buttons to select the value that corresponds to the thermocouple or RTD type
that will be attached to the controller. See the table below for specifications. Press the ; button to save the
selected value. The controller will display the module information splash screen for three seconds and then
return to the main screen.

2. Press the

;

button for three seconds again. Press the

•

button to access the

tpun

parameter. Use
the , and . buttons to select either C for Centigrade or f for Fahrenheit display. Press the ; button
to save the selected value. The controller will display the module information splash screen for three seconds
and then return to the main screen.

3. Press the

;

button for three seconds again. Press the

•

button repeatedly until the

tp-H

parameter
appears. Use the , and . buttons to set the maximum value of the operational temperature range. In
operation, if the PV value is higher than the TP-H value, the PV display flashes to indicate an error and the
controller outputs shut off. The SV value cannot exceed the TP-H value. Press the ; button to save the
selected value. Press the • button to access the

tp-l

parameter. Use the , and . buttons to set
the minimum value of the operational temperature range. In operation, if the PV value is lower than the TP-L
value, the PV display flashes to indicate an error and the controller outputs shut off. The SV value cannot be set
lower than the TP-L value. Press the ; button twice to save the selected value and return to the controller
main screen.

4. Press the • button repeatedly until the parameter

sp

appears. Use the

,

and

.

buttons to select

either

0

for a whole degree or

1

for a tenth degree temperature display.* Press the ; button twice to save

the selected value and return to the controller main screen.

5. If the input temperature from the thermocouple or RTD needs to be adjusted, press the ; button for less
than 3 seconds. Press the • button repeatedly until the parameter

tpof

appears. Use the , and

.

buttons to adjust a positive or negative offset to the PV value displayed on the controller. Press the ; button
twice to save the selected value and return to the controller main screen.
