Unpack the control and set it on the bench top where desired. The rubber adhesive feet hold the
unit securely in place.
Plug the power cord from the control into a grounded outlet. The power switch for the control is
located on the front of the unit. Connect the thermocouple (included) to the control along with the
power connection(s) for the load(s).
The 104A PLSM112 and 104A PLSM124 controls can be used with one load. The 104A
PLSM212 and 104A PLSM224 controls can be used with one or two loads. The 104A PLSM312
controls can be used with one, two or three loads. NOTE: The loads do not have to be balanced
but all loads must combine to: 15A max (120V units) or 10A max (240V units).
How to Setup and Operate each Channel
First, connect the heater load and the sensor to the load and sensor receptacles on the front panel. Next, plug the
control line cord into an appropriate 3-wire grounded power receptacle. Push the power switch to the "ON"
position. Wait five seconds for the control unit to energize.
The control is shipped from the factory with the display reading in degrees C. If a display in degrees F is
desirable, press the
UP/DOWN
arrow keys simultaneously for three seconds to access the Setup Page. Press the
Advance
key until the Celsius_Fahrenheit parameter [C-F] is shown in the right display. Press the
UP
arrow key
to change from C to F.
After changing the display, press the
Infinity
key to display the set point temperature and the process
temperature (temperature at the sensor).
To begin the heating application, use the
Up/Down
arrow keys to enter the desired set point temperature. The
PID values in the control need to be set prior to running the system with your
particular heater. The auto-tuning allows the control to adapt PID parameters without those parameters being
manually entered by the user. It also minimizes the amount of temperature overshoot of the set point and
decreases the time required for the process to stabilize.
See page 9 and 10 for instructions on initiating the auto-tune procedure.
Auto-tuning feature allows quick and simple automatic control for the majority of heating applications. This control
is capable of performing other control functions and has a variety of features.
