Procedure 17.
Setting an Unused Sensor to the Disabled Mode
NOTE: This procedure is only applicable for Ultima X Gas Monitors
with more than one sensor.
• The Ultima X Gas Monitor is shipped with the Sensors in the
enabled mode. This means that a sensor missing error condition
occurs if less than three sensors are attached to the instrument.
The Sensor Disabled Mode allows the operator to attach less than
three sensors to an Ultima X MODBUS unit without having an error
condition for the uninstalled sensors. The Ultima X Gas Monitor still
polls the uninstalled sensor for automatic sensor recognition should
the sensor be installed at a later date. An installed sensor cannot
be disabled without removing the sensor module from the Ultima X
Gas Monitor.
To change it, use the Controller to perform the following steps:
1. Press the SEND button.
• The display prompts: SEND?.
2. Press the CAL button.
• The display prompts: Sel Cal Action +
.
3. Press the + or - button until the display prompts: Sensor Disable.
4. Press the ENTER button.
• The display prompts: Sensor Disable>#
5. Select the sensor to disable (1 - 3).
6. Aim the controller at the sensor and ENTER button.
• The Ultima X Gas Monitor Sensor is now changed to disable
the selected sensor. If the sensors module is attached to the
Ultima X gas monitor, the sensor cannot be disabled.
