Table 16 – Fault Actions Parameters

Block Pump Reverse is the default pump reversal action for the (default) faults that make the pump

unavailable. There are three faults which this action does not apply, they are:

• Under-current

• Over-current

• I

T faults

The default pump reversal action for these faults is No Action.

14.9.2 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.

• Navigate to:

• Change this value to the required amount (the default setting is 10 seconds). Note that “Show More

Options” must be enabled to view this setting (section 31.1)

• 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.
