A flashing decimal point on the lower right corner of the display will appear for 3 minutes after start-up,
calibration, bump, or programming. This is an indicator that the 4-20 mA signal is locked at 3 mA and that all
alarm functions are disabled. Once this flashing indicator clears all functions will return to normal.
Aborting the Set-up Mode is achieved at any time by pressing either the
or
key to select "NORM" and allowing the unit to sit for 5 seconds. Once in
the normal run mode the alarm relays*, audio alarms* and 4-20 mA signal*
will be fully functional in 3 minutes.
Bump Testing
This mode disables the audio* and visual alarms, relay outputs*, and freezes
the analog output* at 3.0 mA for all gases except oxygen, which goes to 16.0
mA. In this mode, the display alternates between "BUMP" and the actual gas
reading every half-second for three minutes.
Once the display returns to the normal operation the audio* and visual alarms,
relay outputs*, and current output* will return to normal operation after an
additional three minutes.
Sensor Type
Identifies sensor type currently installed in instrument.
Low Alarm Set-up
This adjustment affects the low alarm visual indicator, on-board audible
alarm* and low alarm relay contact*.
When in the low alarm mode, the display scrolls "LOW ALARM XXXX"
until either of the internal
or
buttons are pressed to alter the setting, or 3
minutes elapse, at which time the set-up mode is aborted and the unit returns
to normal gas readings. “XXXX” indicates the current set point, and decimals
are automatically placed as needed. If the
or
buttons are pressed during
this 3-minute time, the display reverts to a continuous numeric reading, which
indicates the new alarm setting. Five seconds after the last
or
keystroke,
the scrolling message commences with the newly selected setting.
