MultiSmart Installation & Operation Manual
14.8.4 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 “Probe 1 Failed Sensor”
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 any 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).
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.
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.
14.8.5 Advanced Probe Configuration
The probe sensitivity, as of version 2.3 can be configured without going to the advanced screen (see section
14.8.3). Extra probe settings, including probe sensitivity can be accessed by navigating to:
Name Description
Delay (ms) Sets a delay before a probe sensor change is accepted.
Description Text description of the probe.
Sets the sensitivity of the entire probe in ohms.
Sensors Settings for individual sensors in a probe. Normally no need to change these.
Value Settings for deadband and raw min/max values. Normally no need to change these.
