passwords (USB port and keypad), or remotely using the Remote passwords (RS485 and
Ethernet ports). The user can have either Setpoint or Control Level access active, but not
both simultaneously from the same interface. Setpoint and Control passwords must be 3
to 10 alphanumeric characters in length. The Master Level is used for setting and resetting
of passwords, and includes all Setpoint and Control Level access rights. The Master
Password must be 8 to 10 characters in length, containing at least 2 letters and 2 numbers.
The Master Level can define whether the local user is permitted to change Local
Passwords without having to enter the Master Level. The Master Password is encrypted,
and is not viewable from the keypad. If the Master Password is lost, the user should
contact the factory.
After password entry, the access level is maintained until a period of 5 minutes of inactivity
has elapsed, after which the password must be re-entered. A power loss or entering in the
wrong password logs the user out.
Further definition of the access levels is described as follows:
