MultiSmart Installation & Operation Manual
14.9.1 Delay Fail (No Flow) Fault Setup
A predefined fault called Pump n Delay Fail fault is available that monitors a digital input and only faults if
the input does not change state after preset time expires after a pump starts. It is typically used as a "No
Flow" fault but can be used in many other applications that require the status of an input to be checked after
a preset time expires after a pump starts running.
The procedure to configure the Delay Fail fault is listed below. The setup is very similar to any of the
predefined faults except the delay period can only be adjusted in the Advanced menu.
1. Set the Delay Fail Source (Digital Input)
Scroll down to Pump 1 Delay Fail
•
Press Assign
•
Scroll down to the required digital input and press Select
•
Press Back and Save
•
2. Modify the Fault Description (Optional)
Scroll down to Pump 1 Delay Fail
•
Press Configure, modify the description as required.
•
NOTE: The Act Delay shown in this screen is not the timed delay, it only delays the displaying of the
already triggered fault. To avoid confusion leave this set to 1 second.
3. Set the Delay Time
This is the period of time that expires before the state of the digital input is checked.
The Show more options in the Advanced section must be enabled before this fault can be viewed.
•
Navigate to:
•
Check the box (bottom left hand corner) and press Save and then press Back.
•
Now navigate to:
•
Change this value to the required amount (the default setting is 10 seconds).
•
Press Save and press Back twice.
•
Repeat the above steps for each pump that requires a Delay Fail fault.
•
NOTE: Use Delay fault 02 not 01 as this is already used for the Contactor Auxiliary Fault.
If the input changes state before the timed period expires, no fault is displayed. The input is continually
monitored while the pump is running so if the input reverts back to it's initial state then a Pump n Delay Fail
fault is displayed (after the delay period expires).
14.9.2 Configuring General Faults
Up to ten (10) General purpose (or custom) faults can be created. A General fault is typically used when
none of the predefined faults are a close match to the required functionality (based on the name of the fault)
however all the predefined faults can be renamed.
Be aware that the predefined faults are always listed in the Advanced menu under the original name so if
the functionality is not similar it can become difficult to locate the renamed fault in the Advanced menu.
