From the RELAY menu, each of the three relays can be
configured for either normal or failsafe operation. The
default is normal, meaning normally open contacts
will close with the event corresponding the relay
designation. If fail safe is selected the relay will be
normally energized and will be de-energized with the
relays designated event or a power failure.

The Controller can be password protected to prevent
the unauthorized editing of setup parameters. When
password protection is enabled, an operator may
still navigate between screens to observe settings
or monitor network status. The unit is shipped with
password protection OFF. Entering a 3 digit (non-
zero) password enables password protection. After
protection is enabled, the user will be prompted to
enter the password when an attempt is made to edit
a setup parameter. After entering the password, a 30
minute time period will be allowed for entries, after
which the user will again be prompted to re-enter the
password. To disable password protection, simply
change the password to all zero's (000).
Selecting FACTORY RESET will revert all user
settings to their factory out of box defaults. A
confirmation screen will ask the user to confirm their
intent since user settings will be lost and you will
need to re-configure each channel. For this reason
record settings in each channel edit screen before
performing a reset.
Pressing a CHx key from the main screen will bring up
a channel summary screen with detailed information
collected from the gas detector assigned to that
channel.
Prior to setting channel parameters, the installer
should verify and record the instrument type, node
address and baud rate for each connected detector.
All detectors must be set for the same baud rate,
either 9600 (default) or 19200, and must have a
unique node address. The BAUD setting in the
MODBUS CONFIG menu must match the settings
of the detectors. The channel setup screen may be
accessed either by selecting CHANNEL CONFIG from
the main menu or by pressing the channel number key
twice at the main screen. For each detector channel
