1.11 PIN Number
In order to modify anything other than the pump auto/off/manual settings, the operator must enter a 4-digit PIN number.
Once the PIN is correctly entered, the system remains unlocked for 15 minutes, after which the PIN will need to be
entered once again. While unlocked the PIN number can be modified through the configuration settings edit menu.

The system information screen also facilitates changing the serial number – this is done by pressing the OK button.
Note that the PIN number is required to change the serial number.
To enter the PIN number, simply use the left and right buttons to select the digit and the up and down buttons to change
the digit. The default PIN number is 1234.
Note that there is no penalty for entering an incorrect PIN – the HMI will simply return to the previous screen and the
opportunity to enter the PIN will again be presented.
1.9 4-20mA Display Modes
When the APC6 current loop mode is enabled the HMI is able to report the current 4-20mA reading (this is shown on
the inputs menu screen). In addition, it can convert this reading into one of two types of scale: metres or kPa. The
metres scale can be adjusted for a maximum range of 0.1 to 25.0 metres (in 0.1m increments) and the kPa scale can
be adjusted for a maximum range of 10 to 2500kPa in 10kPa increments.
