Watlow EHG SL10 User Manual

Series EHG SL10

Integrated Temperature Controller

User’s Guide

The Series EHG SL10 is a powerful instrument that in­tegrates a temperature process controller, high-low tem­perature alert, and power switching with a safety high
limit that meets UL® 1998 and CE 60730 requirements.
The optional display and communications modules can
be easily upgraded in the field to provide a digital dis­play, adjustable control parameters, RS-485 MODBUS
communications and other interface features. The com­pact design, inherent reliability and integrated safety
limit functions make this control a tremendous value.
The control is designed for easy integration with Wat­low heaters providing additional value to simplify the
engineering and component count on new equipment.
CE compliance and UL recognition will reduce time and
costs necessary for global agency testing and validation
for OEMs.

Navigating the Series EHG SL10 with the Front Panel

The three-character display normally shows the process
temperature. To view and change the existing Set Point
value follow the steps below:

1. Press the Mode Key once. The right decimal point

will illuminate when viewing the Set Point value.

2. Press the Up-Arrow or Down-Arrow Key to change

the Set Point.

3. Press the Mode Key again to return to the process

temperature display.

The display will automatically return to showing the
process temperature after three seconds.

To view or change parameter values follow the steps
below:

1. Hold down both the Up-Arrow and Down-Arrow Keys
for five seconds.

This will display the Set Point High Limit prompt.

2. Press the Mode Key to view the other parameter
prompts.

3. Press the Up-Arrow or Down-Arrow Key once to view
a parameter’s value.

4. Press the Up-Arrow or Down-Arrow Key to increase
or decrease that value.

5. Press the Mode Key to again display the prompt and
again to display the next prompt.

6. Press the Mode Key at the Display Build Number
prompt to return to the process value display.

Proportional Control

Some processes need to maintain a temperature or
process value closer to the set point than on-off con­trol can provide. Proportional control provides closer
control by adjusting the output when the temperature
or process value is within a proportional band. When
the value is in the band, the controller adjusts the out­put based on how close the process value is to the set
point.

The closer the process value is to the set point, the
lower the output power. This is similar to backing off
on the gas pedal of a car as you approach a stop sign.
It keeps the temperature or process value from swing­ing as widely as it would with simple on-off control.
However, when the system settles down, the tempera­ture or process value tends to “droop” short of the set
point.

With proportional control the output power level
equals (set point minus process value) divided by the
proportional band value.

Adjust the proportional band with Proportional
[`Pb].

On-Off Control

On-off control switches the output either full on or full
off, depending on the input, set point and hysteresis
values. The hysteresis value indicates the amount the
process value must deviate from the set point to turn on
the output. Increasing the value decreases the number
of times the output will cycle. Decreasing hysteresis im­proves controllability. With hysteresis set to the lowest
value of 3°C or 5°F, the process value would stay closer
to the set point, but the output would switch on and off
more frequently, and may result in the output “ chatter­ing.” Both the control mode ([Cnt] prompt) and hyster­esis ([Hys] prompt) values can be changed either using
the front panel or via Modbus communications.

The heating action switches off when the process

temperature rises above the set point.

Proportional Control

Time

Proportional plus Integral (PI) Control

The droop caused by proportional control can be cor­rected by adding integral control. When the system
settles down, the integral value is tuned to bring the
temperature or process value closer to the set point.
Integral determines the speed of the correction, but
this may increase the overshoot at startup or when
the set point is changed. Too much integral action will
make the system unstable. Integral is cleared when
the process value is outside of the proportional band.

Integral [Int] is measured in minutes per repeat. A
low integral value causes a fast integrating action.

Proportional plus Integral plus Derivative (PID)
Control

Use derivative control to minimize the overshoot in
a PI-controlled system. Derivative [dEu] adjusts the
output based on the rate of change in the temperature
or process value. Too much derivative will make the
system sluggish.

Wiring the Series EHG SL10 Communications Ports

The graphic below reflects the control being held up­right with the display facing the holder. As shown, there
are two jacks on the top of the communications module
(RJ45 like, with 4 pins on each) which can accommodate
either a four or six 6 pin modular plug. Communications
from a PC to any EHG SL10 controller on the network
can be established by connecting it to either of the two
available jacks. The other jack can then be connected to
other EHG SL10 controllers on the network (32 maxi­mum).

Looking at either of the jacks as shown in the graphic
pin identification is from left to right.
