PIN Security

Personal Identification Number (PIN) security prevents unauthorised people from programming the MCULOG control unit. Typically, this is set-up when all the other programming has been completed. As with Bankcards, there is one PIN number.

The factory default is for PIN security to be inactive. To activate, navigate the menu system to the PIN screen and edit a 4-digitpersonal identification number (PIN) that you want. The PIN is edited with the arrow keys and confirmed with the ENTER key; the 4-digit PIN will then be replaced by “- - - -’’to indicate that PIN security is active. (By default, PIN is a 0 if inactive).

Once PIN security is activated, a prompt for the PIN will appear when needed for an activity, such as starting a Wizard. If correctly entered, no further PIN requests are made unless the “Cancel Password” option is selected from the MAIN MENU screen. This menu option appears only after correctly entering the PIN; the option disappears when selected, therefore making the MCULOG secure and prompt for the PIN when needed.

Modes of operation

There are two operating modes for the MCULOG. They are on-lineand off-line.

An open padlock icon indicates the MCULOG is presently in the off-linemode. In this mode, the unit can be programmed providing that you know the security PIN (if set-up). Additionally, the 4-20mA output and all relays are frozen, but the MCULOG continues to log data.

A closed padlock icon indicates that the MCULOG is presently in the on-linemode. In this mode, most of the unit cannot be programmed. However, you will be prompted to go off-line if you attempt to programme whilst in this mode and providing that you know the security PIN (if set-up). Additionally, the 4-20mA output and all relays are not frozen.
