CONFIGURATION PROTECTION
You can protect the configuration of a parameter cycle and prevent undue changes by setting a protection for the device. To do this,
access the parameter
Protection
(
PROt
), present in the cycle Configuration (
Cfg
) >> Calibration (
Calib
), and determine the level of
protection to be adopted, limiting access to certain cycles, as shown in the table below:
PROTECTIO
N LEVELS
PROTECTED
CYCLES
1
Only the Calibration cycle is protected.
2
All Configuration cycles are blocked. The Operation cycle is unblocked.
3
All cycles are blocked, except for the SP configuration.
4
All cycles and parameters are blocked.

Configuration Protection Levels
Once you have set a protection password for a cycle, you will always need to enter it (or until you remove the protection).
4.4.1
PASSWORD
When accessing a protected cycle, you will need to enter the password in the
Password
(
PASS
) parameter, which is shown in the first of the
protected cycles. If entered correctly, this password allows you to change the parameter settings of this cycle.
If you have not entered any password, you can only view the parameters of the protected cycles.
You can set a password in the Password Change parameter (
PAS.C
), present in cycle Configuration (
Cfg
) >> Calibration (
Calib
). To do
so, simply fill in this parameter with the desired password.
The controllers leave the factory with the password set as 1111.
4.4.2
PASSWORD PROTECTION
The controller has a security system that prevents you from entering multiple passwords to get the right one. Once the controller has
identified the entry of 5 invalid passwords in sequence, it will not allow you to make further attempts for 10 minutes.
4.4.3
MASTER PASSWORD
If you have forgotten your password, you can use the Master Password feature. It is composed by the last three digits of the controller serial
number
plus
the number 9000.
The master password for a device with serial number 07154321, for example, will be 9 3 2 1.

COMMUNICATION INTERFACES
4.5.1
USB INTERFACE
N20K48 Modular Controller
has a USB interface on the bottom of its housing. You must use the USB interface to configure, monitor,
and analyze the device through the
QuickTune
software (see
chapter). You must use a standard micro-
USB cable (not supplied) to connect the device to a PC.
The USB port drivers will be automatically installed during
QuickTune
installation.

4.5.2
BLUETOOTH INTERFACE
N20K48 Modular Controller
has a Bluetooth Low Energy (BLE) interface, compatible with smartphones that have Bluetooth modules with
version
4.1 or higher.
The Bluetooth interface allows you to configure the device through the
QuickTune Mobile
application (see
section).
If you enable the device Bluetooth interface (
CFG
>>
CaLib
>>
BLE.E
→
yes
) and successfully connect the
N20K48 Modular Controller
to the
smartphone, the device display will display the Bluetooth flag.
It is not necessary to add the device to the smartphone. The connection is made automatically by the
QuickTune Mobile
.
The USB interface is NOT electrically isolated from the input and OUTA circuits.
Its purpose is for temporary use during CONFIGURATION AND DIAGNOSIS of the device.
