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 temperat re controller. Make s re to eval ate any dangero s application in
which a serio s h man inj ry or serio s property damage may occ r.
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) EM / RF (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.

5. Optional regulation parameters can be programmed for a second
control output. f this is desired, access the regulation mode again by
pressing the ;button for less than three seconds. Press the '
button until the parameter Coef appears. This value allows the cooling
control to have a different proportional setting than the heating loop. The
heating loop proportional band setting is multiplied by the Coef value to
create a proportional band setting for the cooling loop control. Use the
,and .buttons to change this value if desired. Press the ;
button to save the selected value. Press the 'button to access the
parameter dead. Use the ,and .buttons to enter a deadband
zone value around the setpoint where the output is not effected by the
proportional control value. As long as the PV remains within the deadband
zone the output is not affected by the proportional control. The integral and
derivative controls ignore the deadband setting and may cause the output
to be on within the deadband zone. Press the ;button twice to save
the value and return to the controller main screen.

Manual Control
1. Access the nitial Setup mode by pressing and holding the ;button for three seconds. Press the '
button repeatedly until the parameter Ctrl appears. Use the ,and .buttons to select manu for
manual control. Press the ;button twice to save the selected value and return to the controller main screen.
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. f 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 'button to access the parameter out2.Use
the ,and .buttons to set a value between )0 and 10)0 to control output #2 directly. Press the ;
button twice to save the selected value and return to the controller main screen.

Dual Cooling / Heating Loop with PID Control
1. Access the nitial Setup mode by pressing and holding the ;button for three seconds. Press the '
button repeatedly until the parameter Ctrl appears. Confirm the default value Pid is selected for P D
control. Press the 'button to access the parameter s- C.Use the .button to select 2C1 for
controlling a dual cooling / heating loop. This parameter sets the cooling control to output #1 and the heating
control to output #2. Press the ;button twice to save the value and return to the controller main screen.
2. Press the 'button to access the parameter r-s.Verify that the default value run is selected. Press
the ;button to return to the controller main screen.
3. Refer to Section 12-1 of this Quick Start Guide to set up the P D control parameters.
4. f the temperature controller’s output #1 is discrete, access the regulation mode again by pressing the ;
button for less than three seconds. Press the 'button repeatedly until the parameter Clpd appears. Use
the ,and .buttons to set the time period in seconds for the cooling output. Press the ;button to save
the value. f the temperature controller’s output #2 is discrete, press the 'button repeatedly until the param-
eter Cpd appears. Use the ,and .buttons to enter the cycle period for output #2, the heating output.
Press the ;button twice to save the value and return to the controller main screen.
5. Optional regulation parameters can be programmed for additional dual
loop control. f this is desired, access the regulation mode again by
pressing the ;button for less than three seconds. Press the '
button repeatedly until the parameter Coef appears. This value allows
the heating control to have a different proportional setting than the cooling
loop. The cooling loop proportional band setting is multiplied by the
Coef value to create a proportional band setting for the heating loop
control. Use the ,and .buttons to change this value if desired.
Press the ;button to save the selected value. Press the 'button to
access the parameter dead.Use the ,and .buttons to enter a
deadband zone value around the setpoint where the output is not effected
by the proportional control value. As long as the PV remains within the
deadband zone the output is not affected by the proportional control. The
integral and derivative controls ignore the deadband setting and may
cause the output to be on within the deadband zone. Press the ;button
twice to save the value and return to the controller main screen.

The SL4824 series temperature controller has one alarm output, ALA1. Alarm group ALA1 can be programmed
for one of seventeen different alarm types. To set up the alarm output, press the ;button for three seconds.
Press the 'button repeatedly until the parameter ALA1 appears. Use the .button to choose the set
value for the desired alarm type. Refer to the chart below for alarm type information. Press the ;button to
save the selected value. Press the ;button repeatedly until the controller returns to the main screen.
The alarm output limits are controlled by the parameters Alnand Alnl, where “n” corresponds to the alarm
output group chosen. After setting the alarm type for ALA1, press the 'button repeatedly until the parameter
Alnand/or Alnlappears. Use the .and ,buttons to enter the high and/or low values for alarm
group ALA1. Press the ;button to save each selected value. Press the ;button again to return to the
controller main screen.
ALA1 is a SPST resistive load 3A @ 250 VAC, normally open relay output.
