7.7 Fault Log.
The controller will log a minimum of 30 historic fault conditions in non-volatile memory.
This includes faults that have been acknowledged via the operating screen.
Access to the list of stored faults is through the Engineers menu.
Faults can be cleared from the list.
7.8 Uploading the Fault Log.
The Fault log can be upload to a memory stick at any time by simply inserting a standard size
USB memory stick into the USB port found on the reverse of the display unit.
Wait approximately 5 seconds, observe the Status LED on the front panel changing colour
and returning to its previous state, then remove the USB stick. The Fault log outputs a simple
text file. Example below:
Fault 41 of 43
Fault Type - System1 Low Pressure
Date - 09/06/2017
Time - 08:13
7.9 Programmable Outputs.
The PHT controller has three programable digital outputs.
These outputs are designated
Programable output 1 – Physical naming D06
Programable output 2 - Physical naming D07
Programable output 3 - Physical naming D08
These outputs can be programmed with one or as many of the fault options as needed.
Programmable Output 1(DO6), Output 2 (DO7) and Output 3 (DO8).
With PHT-N/D/F/V units the above outputs can programmed to be activated by any combination of
the following faults:
•
Pump 1 Over Current
•
Pump 1 Under Current
•
Pump 2 Over Current
•
Pump 2 Under Current
•
Low Water
