we constantly strive to improve our products and services, so we reserve the right to make changes to the prod­ucts and/or publications at any time without notice and without obligation. This publication may also discuss
features that may not be available in certain revisions of the product.

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, drip-

ping 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 overcurrent

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.

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

2. Press the

'

button to access the parameter

out1

. Use the

,

and

.

buttons to set a value

between

)0

and

10)0

to control output #1 directly. If the controller has a discrete output, a value of

2)0

turns the output on 20% of the time. A value of

10)0

would turn the output on 100% of the time. A manually
controlled analog output value is a percentage of the analog signal. For example, if the controller has a 4-20mA
current output, a setting of

)0

would mean that the output would be 4mA. The output would be 20mA with a

setting of

10)0

. Both types of manually controlled outputs are off with a value of 00. Press the

;

button

to save the selected value. For dual output control, press the

Alarm Outputs

Note: ALnH includes AL1H, AL2H and AL3H. ALnL includes AL1L, AL2L and AL3L.

There are up to three groups of alarm outputs (ALA1, ALA2, ALA3*). Each alarm group can be programmed for one of seven­teen different alarm types. To set up the first alarm output, press the

;

button for three seconds. Press the

'

button

repeatedly until the parameter

ALA1

appears. Use the

button to proceed to

ALA2

and/or

ALA3

*

. Follow the same procedure to program these additional

alarms. When the desired alarms are programmed, press the

;

button repeatedly until the controller returns to the main

screen.

The alarm output limits are controlled by the parameters

Alnh

and Alnl, where “n” corresponds to the alarm output group

chosen. After selecting the desired alarm group(s), press the

'

button repeatedly until the parameter Alnh and/or Aln

l

appears. Use the

.

and

,

buttons to enter the high and/or low values for each group of alarm outputs selected. Press

the

;

button to save each selected value. Press the

;

button again to return to the controller main screen.

ALA1 and ALA2 are both SPST resistive load 3A @ 250 VAC, normally open relay outputs. ALA3 uses the same output as
output #2 and is the same type of output.

13

*Note: When output #2 is used, ALA3 is disabled. ALA3 is available only for single output loop control.
