SLC4075 TouchScreen Gateway Installation & Operating Manual
GENERAL INFORMATION
Introduction
The SELECTRONIX, INC. SLC4075-n, TouchScreen
Gateway (TSGW) is a human-machine interface that
is used with our SUPERSTEP SERIES 4000
controllers and optionally our SLC4060, Process
Gateway (PGW). It provides an interface to building
management systems that use the BACnet, Modbus
protocols or many other supported protocols.
The TSGW, SLC4075-4 is based on the Red Lion
CR1000 Operator Interface, which has a 4.3” TFT, touch
screen color display, while SLC4075-7 has a 7” screen,
and the SLC4075-10 has a 10” screen. References to
TSGW or SLC4075 apply equally all units.
The unit is configured using Red Lion’s Crimson 3.1
software, which is a free download. This unit supports
over 300 protocols which may be mapped to the internal
data points.
The TSGW contains a pre-programmed database and
BACnet/IP and Modbus addresses for the accessible
parameters. The parameters are listed in Table 2, Building
Management Interface Variable Assignment
The SLC4075, CR1000-based units have an SD card slot
for upgrading the database in the field. This allows for
easy field upgrades with operating personnel. It also has
a System Menu mode that enables configuring the
network parameters from the front panel, so initial
commissioning may also be performed by the local
network administrator, also eliminating the need for a PC
configuration download to the unit. An internal battery
maintains the realtime clock. These features may reduce
or completely eliminate the need for the on-site
configuration using the Crimson 3.1 software.
Communication interface is via a 10/100-base-T Ethernet
port, or an asynchronous RS-232/422/485 port. Non-
volatile memory is provided to store configuration and
other vital information.
An optional NEMA 4/IP65 enclosure is available.
Power for the unit TSGW is 24V dc +/- 20%. The power
for the SLC4075-4 is provided by an auxiliary 24V output
of the SLC4060. Power for SLC4075-7 or SLC4075-10
must be provided by an external 24V dc power supply.
Status LEDs on the front page of the touchscreen shows
the individual elements that are activated, along with a
numerical readout of the percent of step command and
load limit, for both the Auxiliary and the BMS control. A
large “AUX/DDC” 2-position switch, duplicated on every
page, allows for convenient status and control of the
equipment. This switch allows control of the SLC4000 by
an external signal when in the “Aux” (Auxiliary) position
OR by an internal PID loop using Direct Digital Control,
“DDC”.
Additional pages provide for detailed information, status,
and ability to change individual configuration and
customization settings.
Classic Lead Lag (CLL) is an optional feature that
provides most of the traditional forms of Lead/Lag control
for multiple boiler configurations. CLL provides several
control profiles along with individual control of cascaded
SLC4000 units. The SLC4060 (PGW) relays or
SLC4000-configured XRelays may be used to control a
circulating pump per boiler, including On and Off delay
control.
SLC4080 provides the capability to add 8 additional
isolated digital inputs, which uses 24 V dc excitation.
The standard SLC4000, using the dedicated input
configuration, provides 8 additional relays outputs.

PID Tuning Procedure
The PID control loop is designed to accommodate a very large range of control installations, and as such may require
adjustments from the default values to provide the desired control characteristics. The following steps provide a guideline
for establishing the correct settings.
1. Start with the actual temperature or pressure well below the high limit so that the recovery rate-of-change, and
overshoot may be monitored. Ideally, the initial starting point is a cold plant.
2. Enter a set point which is above the actual temperature or pressure by the worst-case differential, but still well below
the high limit so that overshoot may be monitored.
3. Start with a typical P = 1000, I = 5, and D=0,
4. Enable the system and observe the following responses:
a. the initial rate of change of the step command output, which drives the step controller or flame controller.
b. the initial rate of change of the actual temperature or pressure.
c. the rate of change of the step command output as the actual temperature approaches the setpoint.
d. the amount and duration of temperature or pressure overshoot.
5. With an SLC4075 firmware version of 2.17+ and an SLC4060 firmware version of 1.70+, the derivative calculation
has improved sensitivity for a slowly changing process variable, such as a steam plant, where the pressure may change
1%-5% in a minute.
a. Enter a D =100 and repeat the response tests, observing the effect when the process variable approaches or
exceeds the set point.
b. Adjust the D value as applicable.
6. An alternative to using a D value for systems with high thermal inertia, is to increase the On Delay timing on the
SLC4000. The On Delay may be adjusted from 1 to 8 minutes. SW2-2 through SW2-4 set the integral minutes from 0
to 7 minutes. RV1 sets the On Delay seconds, which is added to the On Delay minutes.
7. If the output response is too slow, adjust the P value higher or vice versa if the response cause unacceptable overshoot
or results in oscillating instability. The approximate output contribution by the P value is calculated in the example
below:
a. As the actual temperature approaches the setpoint, the P contribution decreases to 0, and any step command output
is due to the accumulated integral.
b. If an unacceptable amount of overshoot occurs, then decrease the P value and set the I value to 0.
c. If the recovery rate with the level of P, An alternative to decreasing the P, enter a D value of 100 and observe the
effect on the rate of change of the process variable. For systems with a high thermal inertia, such as a steam plant,
d. Retest until the P value results in little or no overshoot
e. Adjust the I value by observing the amount of droop below the setpoint and the desired recovery time. If the
actual temperature does not recover within the desired time, slowly increase the I until the recovery time to
setpoint is acceptable.
f. Repeat adjustments until the desired response is achieved.
g. Set the desired setpoint and retest to verify the response.
8. TSGW Version 2.15+ and on includes a Trend graph Page 22 that shows:
a. Step Command %
b. RTD1
c. GPA1 in Engr units
The graph is continually updated on a 60 second time period, which may be helpful in tuning the PID. The logged data
is not saved.

9. New feature with TSGW Version 2.17+ and PGW V1.70+ PID Terms
The PID term’s contribution as a percentage of the step command is displayed on the active PID page. This
provides invaluable information in the PID tuning process.
a. The percentage of step command provides insight when determining the initial value of each of the PID
multipliers, as well as when optimizing the interactive integral and derivative values. It shows the relative
interaction between the PID terms under dynamic conditions.
b. The sum of the PID term percentages may add up to more than 100%, even though each term is individually
limited to 100% output.
i. The Integral term’s range is 0 to 100%
ii. Both Proportional and Derivative terms are limited to +/- 100%.
iii. A negative Proportion term occurs when the process variable is above the set point in heat mode, and
vice versa in cooling mode.
iv. A positive Derivative term occurs during a deceasing change in error in heat mode, and vice versa in
cooling mode.

Steam Boilers or plants with high thermal inertia
Steam Boilers or plants with high thermal inertia
For a plant that has a high thermal inertia, such as a steam plant, the application of heat may be applied more
gently, while maintaining a high Proportional value and low Integral value, by increasing the “On Time Delay” of
the SLC4000 master. The delay is adjusted using RV1 in combination with SW2-2 through SW2-4 for a time
delay between steps, from 1 second to 8 minutes. For an SLC4000-1, this time delay is between the application of
the next 1/7th of the full output. The application of the amount of heat is delayed on an increasing demand, while
allowing the rapid removal of heat as the process variable approaches the setpoint. This maintains the benefit
using a high Proportional and low Integral values, resulting in a slower approach to the set point, but a rapid
removal of heat as the process variable approaches the setpoint, minimizing overshoot. The SLC4000 master has
an “Off Time Delay” set by SW2-5, which sets either a 2 or 5 second delay. Verify that this switch is set to ON
for a 2 second delay. This approach is preferable over using a lower P or using a higher I value, as it minimizes
“Integral windup”, which can occur on either plants with high thermal inertia or loads that can rapidly change.

Classic Lead Lag
Classic Lead Lag (CLL) is an optional feature that provides several different sequencing profiles to match specific control
objectives, in addition to providing the ability to define a custom profile.
•The TSGW controls a special CLL version of our SLC4000 step controller.
•Up to 3 expansion units may be cascaded from the master, allowing direct control for up to 4 boilers with up to 8
relays or 4 fuel-based boilers when SLC4000-1 units are used, which have an analog output.
•The Lead boiler may be changed by a pre-set interval from 1 to 1000 hours (41+ days).
•Each of the 4 primary S4Ks are software enabled and disabled, and provide automatic recognition and re-
configuration when a unit’s online status has changed, either due to the lead unit being changed, a limit string
event, or an operator action.
•Auxiliary pilot relays may be activated when an individual S4K has any active output, suitable for signaling
contactors to operate fans or pumps. The auxiliary relays may be on the Process Gateway (PGW) or on another
SLC4000 configured as an XRly unit. On and Off delays may be individually specified for each of the 4
corresponding relays.
•For more details, see “SLC4000Addendum_ClassicLeadLagFeaturesAndControls.pdf” available at
www.selectronix.us in the Support Section.
