Model CAT100
SECTION 3
OPERATION
3-1 STARTUP PROCEDURE
Once the CAT 100 has been correctly as-
sembled and installed in accordance with
the instructions in Section 2-2 (page 2-6),
the analyzer is ready for operation.
Before operating the system, verify that the
leak checks have been performed and that
the sample handling unit is performing cor-
rectly.
Apply power to the system and verify that
sample gas is flowing.
NOTE
A warm-up time of from 15 to 50 minutes
is required depending on the installed
detector(s).
Analyzer operation can be confirmed by the
illumination of the LED displays through the
glass window on the dome. Upon power up,
the analyzer will perform a self-test routine.
This display will initially show the program
version number, after which the concentra-
tion values or error messages will display.

NOTE
In the case of a battery failure in the ana-
lyzer, the programmed values will revert
to defaults and the display will flash
“batt” on power up. This message will
disappear after activating any pad. The
battery maintains the memory for pro-
grammed parameters when the analyzer
is shut off.
3-2 TOUCHPAD
a. Overview
CAT 100 analyzers intended either to
be used in hazardous area or for out-
door use are provided with a Touch
pad. This version ensures ingress pro-
tection (IP) and resistance against me-
chanical shocks.
The Touch pad design requires special
measures to operate the analyzer in a
safe manner. Due to safety reasons
and to avoid unintended operation, the
infrared sensitivity is adjusted in a way
that the Touch pad may not activate
without using the actuator tool.
b. Elements
Whereas standard front panels are us-
ing keys for operating the analyzer, the
Touch pad uses contactless infrared
technology. This results in a slightly
different design.
Each panel key is replaced by two
drilled holes: One for infrared light out-
let and another for entry (Figure 3-1,
page 3-1).
