MultiSmart Installation & Operation Manual
14.8.3 Single-Sensor Mode
The MultiSmart can be configured with less than 10 level sensors – this is called Single Sensor Mode.
Single or three sensor MultiTrode probes or Ball floats may be used.
To configure the MultiSmart for Single Sensor Mode.
1. To Enable Single Sensor Mode go to:
Scroll down to Single Sensor Mode? and check the box. This prevents the "IO Unit 1 Probe Error"
from occurring on the "missing" sensors.
2. To Assign the Sensors go to:
Scroll down and highlight the Primary Probe and press Configure. Now select the probe and press
Config. Unassign sensors not required.
With one of the remaining sensors highlighted, press the Config Sensor button to modify the digital
input or the level represented by that sensor (if necessary).
3. To Verify Digital Input Mode go to:
and press the Advanced button.
For Probes the Mode must be "AC". For ball floats the Mode should be "Digital".
4. To Modify Digital Input Mode go to:
Select the appropriate digital input, expand and scroll down to Mode. Select the correct mode and
press Save.

NOTE:
To avoid an Invalid Input message, the highest level must be assigned to the lowest digital input
used, e.g. for 3 sensors, 100% = Din 2, 50% = Din 3 and 10% = Din 4.
Description
Sets a delay before a probe sensor change is accepted.
Text description of the probe.
Sets the sensitivity of the entire probe in ohms.
Settings for individual sensors in a probe. Normally no need to change these.
Settings for deadband and raw min/max values. Normally no need to change these.
