SUPERIOR™ Gas Detector Series SLD
Single & Dual Channel
This manual covers both single and dual channel SUPERIOR Gas Detectors, and applies to all gasses forwhich sensors are available. Some instructions apply only to Dual Channel (two sensors) MODEL SLD-2
detectors, and are so noted. IMPORTANT NOTE: Chemical Injection Technologies, Inc. recommends
the use of an UPS (Uninterruptible Power Supply) connected directly to the main AC power supply andthen running the Series SLD Gas Detector directly from the UPS device. These devices are readily
available wherever computers are sold. They offer complete functioning of all features in the event of
power loss, as well as excellent power surge and lightning protection. An optional internal battery backup
is available, but like all other similar types of instrumentation, these internal backup power supplies only
allow limited functions, to conserve power, and do not offer any surge or lightning protection.

QUICK START GUIDEINSTALLATION:
1). Mount the SUPERIOR Series SLD Controller/Monitor at eye level. Mount the sensor(s) 12" (30.5 cm)
off the floor in the area(s) where the gas level is to be monitored. The SUPERIOR Series SLD is
supplied with 25 ft. (7.6 meters) of 2-wire cable, for each sensor. Sensor(s) may be located up to
1000 ft. (305 meters) from the controller/monitor.
2). Standard cable(s) is attached at the factory. If it is necessary to disconnect a cable, in order to run
through walls or conduit, etc., note the connections so they can be re-connected properly. If in doubt,
consult the wiring and connection diagrams at the back of this manual.
3). Turn on AC power to the controller/monitor. On power-up, a two (2)minute delay is started to allow the sensor device(s) time to stabilize,
which prevents false alarms. First, the countdown timer is

displayed and then the main run screen is displayed.
4). The MAIN RUN SCREEN will display both channels if they are enabled inModel SLD-2, or just the single channel if the unit is Model SLD-1.
Detector is ready to operate. To change or adjust options & settings, see

The display is a backlit LCD (Liquid crystal display) consisting of two(2) lines each containing a maximum of sixteen (16) characters. The
top line displays a selected value along with its engineering units.
The bottom line normally provides function labels for the four (4)pushbuttons located below the functions. The functions are linked tothe specific menu being displayed, and will vary depending on thenecessary operator input. The push buttons are labeled F1, F2, F3,
and F4.

MAIN MENU
1). Press any function button on the Main Run screen and immediately
release. The MAIN MENU will appear for approximately four (4)seconds, and after 4 seconds the display will return to the main run
screen. You may push any of the function buttons again if the MAIN
MENU screen reverts to the main run screen before you choose one of
the function buttons.
ALM =MAIN MENU
ALM LOG TEST CFG

Allows operator to set both the low level (Warning) and high level (Danger) alarm set points,
for each channel. The alarm set points are password protected. Factory default settings
are: DANGER = 1 PPM, WARNING = 3 PPM.
LOG = Allows operator to view the EVENT LOG which records each time the gas level goes above
a set point. It will also log any accesses to the CALIBRATION/PARAMETER programs ifchanges are made. Up to 256 events can be logged . Events cannot be cleared.
TEST = Energizes all relays to test the alarm devices.
CFG = Allows operator, with password access, to calibrate the sensor inputs, and the monitor
analog outputs. It also allows access to the program parameters and “real time” clock time
& date settings.
