Initial Startup

The first time the ULTIMA X5000 is powered on, the analog output goes to the Maintenance Mode setting (default 3.5 mA) and the following will appear on the display while the LEDs cycle from GREEN, to RED, to AMBER, then to GREEN:

•

ULTIMA X5000 Logo with Software Version No.

•

Tachometer countdown

•

MSA Logo

The ULTIMA X5000 will remain in start-up mode in which the fault relay is energized and the analog output is at its maintenance level, 3.5 mA by default. The time the X5000 stays in start-up mode is dependent on the warm up time of the sensor. See Reading Level for each sensor. If a dual sensor configuration is deployed, each sensor is able to exit warm up independently.

A full calibration is recommended after one hour of a sensor being installed, powered up, and acclimated to the environmental conditions. See Calibration for details.
